The Ford Expedition is a full-size SUV built by the Ford Motor Company. Introduced in 1996 for the 1997 model year as a replacement to the Ford Bronco, it was previously slotted between the smaller Ford Explorer and the larger Ford Excursion, but as of the 2005 model year, it is Ford's largest and last truck-based, off-road and tow capable SUV. It has usually shared a platform and design with the Ford F-150 pickup truck. Ford currently offers the standard regular-sized model and the larger EL/Max model, succeeding the Excursion which was discontinued in 2005. It is the second Ford vehicle to use the Expedition name, as it was part of the Explorer Sport's trim models during the 1995 model year. All Expeditions were originally built in Wayne, Michigan. In 2009, Ford shifted its current third generation (2007–present) model production to Louisville, Kentucky when Ford converted the Wayne assembly plant to begin further production of the Focus. A fourth generation will arrive to dealers in 2014 or 2015.

Vehicle background

The Expedition offered up to nine passenger seating in model years before 2007 (with a front bench seat option); 2007–present offer 2 bucket seats in the first row.[2] It is equipped with a V8 engine. It is similar to the Lincoln Navigator, especially for the 2007–present model in Limited or King Ranch high end trims; both of which were introduced for the 2005 model year. With the 2011 model year Ford made changes in the base level department, with the newly designated XL trim a standard and upgrading the XLT to second level and replacing the Eddie Bauer trim that was phased out from the entire Ford vehicle lineup. As of 2010, over 1,545,241 Expeditions (both standard and EL/Max) have been sold since its introduction. A specially modified Special Service Vehicle version is also available from Ford for law enforcement agencies, fire departments, and EMS agencies.

Known internally at Ford as the UN93, the first generation Ford Expedition was developed under the UN93 program.[3] The all-new full-size SUV was introduced in late 1996 as a 1997 model, replacing the aging two-door Ford Bronco in Ford’s vehicle lineup. Expedition featured optional three row seating, first row captains chair luxury seating, available second row captains chair luxury seating, genuine premium leather seating surfaces (imitation leather was not available for Expeditions) illuminated running boards, heated side view mirrors, power moon roof, dual zone climate control and Ford’s premium Mach audio sound system with rear subwoofer. Many of these features were standard on the top-of-the-line Expedition Eddie Bauer. Expedition XLT served as the entry level model.

Expedition was available with automatic ControlTrac four-wheel drive with two-speed dual range BorgWarner 4406 transfer gearbox and intelligent locking center multi-disc differential. ControlTrac was first introduced on the 1995 Ford Explorer, although the Expedition received its own transfer gearbox designed for high torque output. The system included four driver selectable modes: Two High, Auto, Four High (lock) and Four Low (lock). Two High mode and Auto mode with auto-lock wasn’t available on the Explorer’s system.[4]

The Expedition’s mechanicals consisted of a short & long arm (SLA) independent front suspension, multi-link rear live axle and speed sensitive power assisted steering. Optional equipment included off road under body skid plate protection, Traction-Lok rear limited-slip differential and a heavy-duty trailer tow package.

Expedition was also available with an adaptive, electronically controlled pneumatic air-ride suspension system that would raise and lower the vehicle depending on road and load conditions. The system also included a kneel down mode which would lower the Expedition down to allow easier ingress and egress as well as loading cargo.[5] Similar to how a camel kneels down to allow a rider to climb aboard.

Engine choices consisted of a standard 4.6 liter Triton V8 or an optional 5.4 liter Triton V8. The first generation Expedition was rated as a Low Emission Vehicle (LEV).[6] The latter engine combined with the heavy-duty trailer tow package and appropriate axle ratio can achieve a towing capacity of 8,100 lbs (3,674 kg).[7][8]

The F150 and Expedition benefit from shared parts bin especially with collision parts.

Safety and security

Initially, a two-air bag supplementary restraint system (SRS) with two-way occupant protection was standard on Expedition. The system included adaptive dual front air bags for front seat occupants. The air bags would adjust deployment force depending on crash severity. Other features also included SecuriLock with smart key and engine immobilizer, security approach lamps, four-wheel anti-lock braking system (ABS), side intrusion door beams, post crash fuel pump shut-off and three-point safety belts for all rows of seating with tension and locking retractors.

An optional four-air bag supplementary restraint system (SRS) with four-way occupant protection became available for the 2000–2002 model years. Dual front seat side impact air bags were added (bundled with the ultrasonic rear park assist) for upper torso protection. The side impact air bags can be identified by an oval badge reading "Air bag" attached to the outboard front seat bolsters.

2002 model Expeditions introduced the BeltMinder system which would detect when the driver didn’t have his/her safety belt secured. An audible alarm would sound, in the form of a warning chime, until the driver’s safety belt was fastened.

Model year changes

1998

No major cosmetic or mechanical changes. A new exterior color was added, Wedgewood blue.

1999–2002 cosmetic facelift

1999

For the 1999 model year, the Expedition received a facelift very similar to that of the 1999 Ford F-150. Included in the update was a new front grille which now dropped lower in the center, grille work (that contained the Ford oval badge), as well as an all-new front bumper that now incorporated the fog lamps into the lower valance and larger center air intake. Both the 4.6 liter and 5.4 liter V8 engines received updates including more power and torque. The Two High mode for automatic ControlTrac four-wheel drive equipped Expeditions was dropped leaving only Auto, Four High (lock) and Four Low (lock) modes. The dashboard also received an updated radio and A.C.

2000

Available features on 2000 model Expeditions were expanded to include a hidden radio antenna (integrated into the rear quarter panel window glass) power adjustable accelerator and brake pedals, Gentex auto dimming electrochromatic rear view mirrors, lane departure indicators on side view mirrors (before on the glass) and ultrasonic rear park assist /backup sensors. The lower front bumper valance and illuminated running boards were changed over to Arizona beige to complement the standard Arizona beige exterior body trim on Eddie Bauer models.

2001

New trim packages became available for Expedition XLT and Expedition Eddie Bauer models. XLT versions could be optioned with the XLT No Boundaries package which included monochromatic Solid black paint work with chrome grille and special alloy wheels. Eddie Bauer versions could be optioned with the Eddie Bauer Premier package which included either monochromatic Arizona beige or Solid black paint work with painted alloy wheels and upgraded premium leather seating.

2002

No major cosmetic or mechanical changes. Last year model for the UN93. This was also the last model year for XLT No Boundaries and Eddie Bauer Premier trims.

The redesigned second-generation Ford Expedition was developed under the U222 program code name.[3][10] The new Expedition was introduced in 2002 for the 2003 model year and featured a new four-wheel independent long-travel suspension system, becoming the first full-size body-on-frame sport utility vehicle to use a fully independent suspension.

The new independent rear suspension (IRS) was perceived as being controversial by some at the time of its introduction.[11] A misconception was that the Expedition’s towing and off-road capabilities would be reduced, in comparison to the previous generation’s rear live axle. Nevertheless, underbody obstacle clearance improved by half an inch, and up to two inches under the axle differentials.[12] The new suspension reduces rear unsprung mass by 110 pounds, and allows for a full 9.4 inches of suspension travel (how much the wheels can travel up or down) improving its ability to traverse uneven terrain for improved control and ride quality.[13][14] The four-wheel independent long-travel suspension itself is a purpose-built version of race suspensions found on off-road desert race vehicles.[15]

Towing capacity increased by 800 lbs (363 kg) for a high towing capacity of 8,900 lbs (4,037 kg) when properly equipped with the appropriate axle ratio and heavy-duty trailer tow package.[16] Payload capacity was increased up to 1,614 lbs (732 kg). Expedition also gained a hydroformed fully boxed frame providing a 70 percent improvement in torsional stiffness.

Along with the high towing capability came all-new steering, braking and electronic systems to help the Expedition better control and maneuver long heavy trailers. Adaptive variable assist power rack-and-pinion steering was introduced along with the largest brake rotors in the segment at that time (13.5 inches up front, 13 inches in back) with brake calipers 100 percent stiffer than the previous generation Expedition. The four-speed 4R70W automatic transmission received all-new control software to allow the transmission to automatically adjust to the demands of towing, using new computer logic that recognizes changes in load and road conditions.[16]

The automatic ControlTrac four-wheel drive system remained available, with an uprated two-speed dual range BorgWarner 4416 transfer gearbox. The new transfer gearbox featured an intelligent locking center multi-disc differential that could now "torque bias" in Auto mode. A new dedicated microprocessor with new control software was added allowing the system to detect different terrain and surface conditions to predict traction loss before it happens. Two High mode was also reintroduced. Four-wheel electronic traction control was now available as an option, and simulated front and rear differential locks.[15]

The V8 engines offered on the previous generation were carried over, but not without major changes and improvements. Both the 4.6 and 5.4-liter Triton V8 engines received further refinements in design and overall efficiency. Expedition qualified as an Ultra Low Emission Vehicle (ULEV) and was certified under the Environmental Protection Agency Tier 2 regulations one year earlier than required.[17] The 4.6-liter engine received an all-new redesigned cast aluminium engine block optimized for weight reduction and NVH improvements. The 5.4-liter engine received an all-new redesigned cast-iron engine block with computer designed ribbing and bracing, along with thicker side skirts and reinforcement at the oil pan flange. The new engine block helped reduce engine vibration and unwanted noise while providing refined performance.[17]

Both engines featured piston skirts coated with a teflon-based friction-reducing material, and fitted with low-tension, low oil consumption rings. In addition, a new fail-safe cooling mode provided protection even in the case of a catastrophic coolant loss (such as a punctured radiator). In the event of coolant loss, the engine control unit shuts off fuel to alternate cylinders to reduce the risk of engine damage from overheating. The valves continue to operate, in order to pump cooling air through the cylinders. The cooling system was designed to maintain an ideal engine temperature even when subjected to a prolonged 15 percent gradient in 46°C (115°F) weather. A returnless fuel supply system helped to reduce evaporative emissions by providing consistent pressure to the fuel injectors through a high-pressure pump.[17]

New active hydraulic engine mounts were introduced to prevent the powertrain from inducing vibrations into the chassis. By optimizing these engine mounts, the engine block can act as a mass damper, absorbing chassis resonance, improving ride comfort.[17]

Expedition’s passenger cabin was better sealed than before, in an effort to eliminate intrusive outside noise from reaching the occupants. Wind, powertrain, road and vehicle body noise was reduced by improving interior acoustics through new damping materials, a total of 10 shear-style isolating body mounts, heavier sealing of body and panels, redesigned rubber door seals, and extensive use of interior structural acoustic foam in the upper B-pillars, upper and lower D-pillars and floor pan. Road noise was reduced by 2 decibels, body air leakage reduced by 56 percent, chances for sealant noise disturbances reduced from 15 percent to less than 0.5 percent and wind noise measured at 80 mph (130 km/h) was reduced from 35 sones to a world class level of 29 sones.[17]

The Expedition also received a thorough exterior and interior cosmetic redesign. Expedition featured an all-new front fascia, grille work, headlamps, body trim, rear fascia, tail lamps and liftgate. Interior fit and finish were improved with an all-new interior featuring new dash, door panels, genuine aluminium trim, and plush carpeting. Premium perforated leather seating surfaces were standard on Expedition Eddie Bauer (optional on Expedition XLT). Expedition FX4 models featured all of Expedition's optional off road equipment as standard equipment. Expedition’s drag coefficient was 0.41 Cd.[18]

Three-row seating was standard with all-new manual fold-flat stow away third row seats. No longer did owners have to remove the third rows seats for more storage. The third row could simply "disappear" into the floor. Power assisted PowerFold fold-flat third row seating was available as an optional extra.[16] Available features included in-dash CD-ROM based navigation system, DVD based rear entertainment system, ultrasonic rear park assist/back up sensors, power moon roof, power adjustable accelerator and brake pedals (introduced on the first generation Expedition), Gentex auto dimming electrochromatic rear view mirror, lane departure indicators on side-view mirrors, second-row captain's chair luxury seating, premium audiophile sound system with in-dash six-disc CD changer and rear subwoofer[19] and four-wheel independent pneumatic air-ride suspension system.

Safety and security

Like the generation before, a two-air bag supplementary restraint system (SRS) with two-way occupant protection was standard on Expedition. Adaptive dual front air bags for front seat occupants now included the Personal Safety System (PSS). PSS would tailor air bag deployment for driver and first passenger and included occupant classification, seat position, crash severity, safety belt pretensioner, load limiting retractor and safety belt buckle usage sensors.

An optional four-air bag supplementary restraint system (SRS) with six-way occupant protection was also available. This new protection system included the new SafetyCanopy head, upper torso and rollover protection side curtain air bags which would deploy along the A, B and C-pillars down to the vehicle’s belt line. SafetyCanopy could remain inflated after deployment for extended protection. SafetyCanopy replaced the front seat side impact air bags featured on the first generation Expedition.

Other features included side intrusion door beams, security approach lamps, SecuriLock with smart key and engine immobilizer, BeltMinder, three-point safety belts for all rows of seating, post-crash fuel pump shut-off, tire pressure monitoring system (TPMS) and four-wheel, four-sensor, four-channel anti-lock braking system (ABS) with electronic brakeforce distribution (EBD) and emergency brake assist (EBA). AdvanceTrac electronic stability control with traction control system was introduced as an optional extra. The electronic traction and stability mitigation system would expand to include roll stability control (RSC) for the 2005 model year.

Model year changes

2003

Before the 2003 model year ended, Ford updated the running boards on Expeditions equipped with the Eddie Bauer trim. Earlier in the model year, Eddie Bauer models had received standard black running boards. Toward the end of the model year, Arizona beige running boards were re-introduced to complement the Arizona beige body work which came standard on Eddie Bauer. Body colored running boards had previously been offered on the first-generation Expedition from 2000 to 2002.

2004

No major cosmetic or mechanical changes. The Expedition Eddie Bauer Premier model is reintroduced after being absent from the 2003 model trim line-up. Monochromatic paint work with blacked-out headlamps and special alloy wheels were standard on Eddie Bauer Premier versions. A new Expedition XLT Sport model is added with Dark Shadow grey exterior body trim. The FX4 trim level was renamed NBX.[21]

2005

Expedition received new roof rails which replaced the traditional sliding cross-bar roof racks. A new high end Limited trim level replaced the Eddie Bauer Premier model (though the regular Eddie Bauer was still available) and featured chrome accented roof rails, chrome-clad aluminium wheels, PowerFold power assisted stowable side view mirrors and chrome tipped exhaust. An upper high end King Ranch trim level with Castano leather seating was also introduced. The base 4.6 liter Triton V8 engine was dropped for the 2005 model year as the 5.4-liter Triton V8 was made standard on all Expeditions and updated with 24-valve technology and variable valve timing. Along with the 2005 model V8 engine update, the Expedition also received a significantly updated version of the four-speed 4R70W automatic transmission.

The new four-speed automatic transmission, now called 4R75E, featured fully electronic Smart Shift technology. A turbine speed sensor improved transmission control and provided the basis for the fully electronic shift scheduling. The transmission's microprocessor speeds were improved for better responsiveness and precision of the control system. The transmission was continuously learning, and would calculate the torque in the next gear and schedule shift points based on the Expedition’s projected performance in the next gear.[22] For 2005 model Expeditions the 4R75E transmission is designated by the letter "B" on the manufacturers safety compliance certification label, located in the driver’s side door jamb. For 2006 model Expeditions, the 4R75E transmission is designated by the letter "Q".

2006

No major cosmetic or mechanical changes. Last year model for the U222. The Gentex auto dimming rear view mirrors were updated. Two new exterior colors were added later on within the model year. They were Pewter metallic and Dark Copper metallic. Medium Flint grey interior was also added to Limited models later on within the model year. Chrome tipped exhaust was made standard on King Ranch models. 2006 would be the last year model for the NBX trim. The ultrasonic rear park assist and SafetyCanopy side curtain airbags were offered as standalone options.[23]

Russian Москва-Чукотка (Moscow-Chukotka) overland expedition

On April 12, 2006, three second generation Ford Expedition Eddie Bauer full-size sport utility vehicles successfully completed an unsupported 32 day off road overland expedition. The heavy-duty 4x4s journeyed nearly 30,000 kilometres across North Asia, the arctic tundra and at times, uncharted territory. The expedition team was made up of six members (two in each vehicle) which included the expedition leaders: Alexey Mikhailov and Alexander Borodin; technical director: Andrey Rodionov and professional off road drivers: Sergey Goryachev, Victor Parshikov and Alexey Simakin. The expeditionary trip was exactly 28,000 kilometres or about 17,398 miles round trip (there and back collectively). The planned route resulted in the SUVs primarily traveling on permafrost and herded the Ford Expeditions across the Arctic Circle twice. The expeditionary team visited landmarks such as the spot where American aviator Carl Ben Eielson was lost, and the birthplace of Russian explorer Semyon Dezhnev. The northernmost point on the route was latitude 69°42′ North (Pevek). The easternmost point visited was longitude 169°40’ West (Cape Dezhnev). The Ford Expeditions endured unforgiving terrain, constant frigid temperatures down to -36 °C (-32 °F), whiteouts and a violent polar cyclone that engulfed the expeditionary team toward the end of the expedition, resulting in the team stopping the vehicles. They remained inside the SUVs for protection during the storm’s nighttime onslaught as temperatures dropped and winds wailed against the vehicle windows. 200 kilograms (440 pounds) of snow were removed from each of the Ford Expeditions after the tail end of the storm swept across them again the following day.

The Ford Expeditions were off-the-shelf production versions equipped with the automatic ControlTrac four-wheel drive system. Two of the SUVs were charged with towing dual axle utility trailers during the journey. The SUVs were lightly modified with front end guards along with front and rear utility bumpers, winches, safari roof racks, high-powered off road lights and extra belly plating for the engines. Because the trip would venture far from civilization, the vehicles were also equipped with gas stoves and high capacity auxiliary fuel tanks (mounted in the rear cargo bay) for when petrol/gas stations became nonexistent. The SUVs still retained their factory stock engines, transmissions, four-wheel drive systems, suspensions, even their factory 17x7 alloy five-spoke wheels. Two of the Ford Expeditions were equipped with caterpillar track systems supplied by Mattracks. The rubber track systems were used when off road conditions became too demanding for conventional tires. Whether directly or non directly related, the rear stabilizer bar failed on the two Expeditions fitted with the Mattracks system. The third Expedition, without the Mattracks, suffered no such problems. The problem was ruled most likely to be a combination of both overloading and extreme off-road conditions. While the issue was fixed and the SUVs continued on with the expedition, the Mattracks however, continued to be problematic. The 5.4-liter Triton V8 engines were sometimes forced to run on poor-quality petrol/gas from unknown sources when high-quality fuel could not be found.[24][25]

The 2007 model year saw the introduction of a new third generation Expedition, developed under the U324 program code name, which was a heavily updated version of the second generation Expedition. Most of the improvements made to the new Expedition were mechanical in nature, though the SUV also received a sheet metal refresh, redesigned interior with upgraded materials and further fit & finish refinements. A new long wheelbase Expedition EL/Max was developed under the U354 program and was introduced as a replacement for the discontinued Ford Excursion.

Expedition’s front end now featured Ford’s signature three-bar grille to complement the SUV's truck DNA relation to the F-150 and Super Duty pickups. New complex stepped style multifaceted headlamps, side view mirrors with updated LED lane departure indicators, sleeker body work and redesigned tail lamps were also added. The interior received a new dash with F-150-like center stack, center console, redesigned first row captains chair luxury seating, door panels and interior trim. The column shifter was replaced by a floor shifter on the center console.

To further reduce outside noise intrusion for quieter, more isolated ride comfort, new SoundScreen laminated acoustic and solar tinted windshield[26] was added with thicker laminated side window glass.

Expedition gained a modified version of the half-ton P2 platform from the F-150, designated the T1 platform. This new platform provides 10 percent more torsional rigidity than the previous generation, and incorporates the four-wheel independent long-travel suspension system (introduced on the second generation) with a redesigned five-link rear suspension and new lower control arms. As with previous model years, the suspension system could be had with adaptive pneumatic air-ride springs.

Additionally, the Expedition is powered by the same 5.4 liter Triton V8 engine, rated at 300 hp (220 kW) and 365 lbf·ft (495 N·m) of torque from the previous generation. When properly equipped with the heavy-duty trailer tow package the SUV can tow up to 9,200 lbs (4,130 kg). Expedition is classed under the Tier 2, Bin 5 / ULEV 2 Ultra Low Emission Vehicle environmental classification.[27]

Ford’s new 6-speed 6R75 automatic transmission with dual overdrive gears was introduced. The transmission featured push-button overdrive lock-out, electronic shift scheduling, adaptive shift algorithms and a mechatronic transmission control module (TCM) that would save adaptive shift data in keep alive memory (KAM). This safeguarded against complete data loss in case of a power failure (such as disconnecting the battery). In the event of a power failure, the mechatronic unit would simply read the last saved data entry from the system’s memory, thus, the transmission did not have to completely relearn the owner’s driving style.

Off road geometry figures for approach, departure and ramp breakover angles are 22°, 21° and 18° respectively.[28] Minimum running (lowest point) ground clearance is 8.7 inches (220 mm). Underbody (overall) ground clearance is 9.1 inches (230 mm).[29]

Selectable automatic ControlTrac four-wheel drive remains available with a two-speed dual range BorgWarner 4417 transfer gearbox and intelligent locking center multi-disc differential. Four-wheel electronic traction control is standard and off road underbody skid plate armor is optional. A new default off road program with throttle response recalibration was added, and is automatically activated when Four Low (lock) mode is selected. Expedition can achieve an off road crawl ratio of 41.06:1 with a low range ratio of 2.64:1 and rear axle ratio of 3.73:1.

The new SUV was unveiled at the Houston Auto Show rather than at Detroit, Los Angeles, or New York where most new models are, as 20 percent of all Expedition sales are in Texas. The third generation Expedition went on sale in August 2006. The first 2007 Expedition to roll off a Ford assembly line was donated by Ford to the Peter family of Jamaica, Queens, New York as part of an episode of the ABC series Extreme Makeover: Home Edition that aired May 7, 2006.

Safety and security

Safety and security features continue to build from the first and second generations.

A six-air bag supplementary restraint system (SRS) with ten-way occupant protection is standard on Expedition.[30] The system consists of adaptive dual front air bags with Personal Safety System (PSS) and SafetyCanopy head and rollover protection side curtain air bags. The SafetyCanopy air bag system was redesigned to include third row seating and features multi-chamber inflation, roll-fold technology and extended inflation after deployment. SafetyCanopy will deploy along the A, B, C and D-pillars down to the vehicle’s belt line. New dual front seat side impact air bags for dedicated upper torso protection were reintroduced, similar to the ones used on the first generation Expedition. The seat side air bags are denoted by a small identification tag reading "Air bag" stitched onto the outboard front seat bolsters.

Other safety features include side intrusion door beams, security approach lamps, SecuriLock with smart key and engine immobilizer, BeltMinder, three-point safety belts for all rows of seating, post crash fuel pump shut-off, tire pressure monitoring system (TPMS), AdvanceTrac electronic stability control (ESC) with roll stability control (RSC), traction control system (TCS), and four-wheel, four-sensor, four-channel anti-lock braking system (ABS) with electronic brakeforce distribution (EBD) and emergency brake assist (EBA). 911 Assist, perimeter alarm and SOS Post-Crash Alert features were added for 2009-onward models.

SOS Post-Crash Alert will activate the Expedition’s horn and continuously flash the hazard/caution lights as well as the lane departure indicators on the side view mirrors after a collision.

911 Assist system will be ready to assist in placing a call to a local 911 emergency operator in the event of air bag deployment. When a phone is properly paired, turned on and connected to SYNC (which happens every time the driver enters the vehicle with his/her cell phone), 911 Assist will provide a 10 second window to allow the driver or passenger to decide whether to cancel the call. If not manually cancelled within the 10 second window, 911 Assist will place the emergency call. A pre-recorded message will play when the call is answered, occupants in the Expedition will then be able to communicate directly with the 911 operator. Once the call is connected, 911 operators can respond to the situation exactly as they would with any 911 call. Emergency services can even determine the medical priority and dispatch the appropriate assistance based on the situation. If vehicle occupants are non-responsive, for example, the location of the vehicle can be determined through voice signal triangulation or by phones with a GPS location feature.[31]

Model year changes

2008

For the 2008 model year, power deployable/retractable running boards became available, along with a rear view backup camera system. The camera, which is mounted under the Expedition’s center liftgate appliqué, utilizes the Gentex auto dimming rear view mirror’s picture-in-mirror technology to display what it sees. Expedition King Ranch was also reintroduced after being absent from the 2007 model year trim line-up. Expedition XLT models now get body colored lower body work, replacing the previous black plastic trim.

2009

In July 2008, Ford's Wayne, Michigan plant started production on the 2009 models until December 2008.[33] In January 2009 production of the Expedition was relocated to the Kentucky Truck Assembly in Louisville along with its sister SUV, the Lincoln Navigator, and the Ford F-Series Super Duty. That plant used to build the Ford Excursion until 2005.[34]

Expedition's 6-speed 6R75 automatic was replaced by an improved version, the 6-speed 6R80 automatic. 6R80 features more robust internals, new software logic and a tow/haul mode (replaces the overdrive lock-out) that utilizes new uphill/downhill gradient shift logic for improved performance while towing or hauling heavy loads. The 6-speed automatic can compensate for altitude, grade/slope and present load conditions. The system also reduces the transmission’s tendency to "hunt" for the right gear(s) and provides engine braking when descending hills. The front bench seating option has been discontinued for the 2009 model year, and the chrome "Expedition" name plate badges have been removed from the left and right front doors. The chrome "Expedition" name plate badge on the rear liftgate remains.

Additional features included the now standard FlexFuel capability, which can take gasoline, E85 (85% ethanol/15% gasoline), or any combination of the two, and the newly installed EasyFuel capless fuel-filler system. The 5.4 liter V8/FlexFuel feature also upgraded its torque power to 310 hp (231 kW) and 365 lb⋅ft (495 N⋅m). The 2009 model year also boosted its maximum towing capacity to 9,200 lb (4,200 kg) for the 4x2 version, and up to 9,000 lb (4,100 kg) for the 4×4 version.

The new entertainment features added to the 2009 model year included the optional Ford SYNC, and an all-new DVD-based voice-activated, multi-entertainment/navigational system with liquid crystal touch display. The rearview camera system is now integrated to show the video feed through the navigation screen instead for the rearview mirror, however, the rearview mirror is still used to show images on Expedition’s not equipped with the navigation system. The new navigation system features up to 10 gigabytes of storage space for more than 2400 songs, a jukebox function, a screened photo display, iPod/Zune capability for downloading and recharging, ripping CDs, and integrated compatibility for cellphones and Bluetooth; the newly compatible Sirius Travel Link, which allow drivers to access traffic, weather, sports, and local movie listings; and a "Route Guidance" mode for road and street information. The steering wheel also has a tilt feature and radio controls, including Ford SYNC buttons, allowing the driver to press the button and use voice commands to activate the system, which became standard on Eddie Bauer, Limited, and King Ranch. The tilt w/radio control feature was optional on the XLT during its Wayne plant built orders, but after production moved to Louisville it became standard. For accessory purposes, a HD radio can be installed upon request at a Ford dealership in the United States.

2010

No major cosmetic or mechanical changes. For the 2010 model year optional packages have now been renamed (to Rapid Specificated Order Codes) and upgraded (100s for XLT, 200s for Eddie Bauer, 300s for Limited, 400s for King Ranch) for the newer models. It has also announced that the 2010 models will now feature Ford's MyKey and trailer sway control as a standard on all trims.[35] The 2010 models were ranked 6th among the top 11 affordable large size SUVs in "US News & World Report.[36] There was talk about making a diesel version of the Expedition for the 2010 model year, but never made it to the planning stage.[37] Rain-sensing windshield wipers were added as an optional extra for Eddie Bauer but standard on the Limited and King Ranch versions.

2011

No major cosmetic or mechanical changes. HD Radio became a standard on all trims, including the navigation system, along with a dual DVD system that is now placed at the headrest area. Another change that was made was in the entry-level trim department, with the Expedition offering the newly designated standard XL entry level with lower black cladding, while the XLT level trim was upgraded along with a new XLT Premium trim with gold cladding, replacing the Eddie Bauer level trim. Also, silver cladding was added as an exterior trim as part of a newly optional XLT Premium Sport Appearance Package. Both Limited and King Ranch trims recive new paint and interior trim. The limited trim also has a chrome grille for a change.[38]

2012

Ford Expedition 2012

No major cosmetic or mechanical changes. The second heated row seating option was added to XLT Premium and the front park assists became a standard feature on the Limited and King Ranch trims.[39]

2013

No major cosmetic changes; however the XL trim and XLT Sport options were dropped, leaving only the XLT, XLT Premium, Limited, and King Ranch trims. The only changes made to the 2013 models (which went on sale in August 2012) are an integrated trailer brake controller that is now included with the Heavy-Duty Trailer Tow Package, a new internal shift control module which allows the six-speed automatic transmission to tailor shifts to engine demand, 10 equipment levels, three new colors (Blue Jeans Metallic, Kodiak Brown Metallic and Ruby Red Metallic Tinted Clearcoat), new 20-inch chrome-clad aluminum wheels, and a dual-head restraint DVD system, which will be available on both the Limited and King Ranch trims. The latter trim will also feature chrome roof racks and side mirrors. Another notable change can be found on the driver's instrumental panel, with the temperature and fuel gauge trading sides.[40]

Fourth Generation (2016)

On January 14, 2013, Ford announced plans for a redesigned version of the Expedition, its first since the 2007 model year. The all new Expedition will stay body-on-frame (BOF) and retain its heavy-duty truck underpinnings, as well as V-8 power for towing and hauling needs.[41]

The new full-size SUV will receive the 5.0 liter 32-valve Ti-VCT V-8 engine which features an aluminium engine block, flex fuel capability, and twin independent variable camshaft timing. Power output for the V-8 is rated around 360 horsepower and 380 lb-ft of torque. The 3.7 liter 32-valve Ti-VCT V-6 could be offered as the entry-level engine making the 5.0 liter V-8 the premium option. The 3.5 liter 32-valve EcoBoost V-6 could also be offered but is more likely to see use in the Navigator.[42]

The Expedition could receive the 10-speed automatic transmission Ford is currently developing, but the SUV may use the current 6-speed automatic transmission until the 10-speed gearbox is ready.[43] When completed, the fourth generation Expedition will go on sale as a 2014 or 2015 model and will stay close to the F-150 in styling, and other features like the previous generations were.[44]

For the 2007 model year, an extended-wheelbase version of the Expedition called the Expedition EL (for "extended length") was introduced in the United States. In Canada and Mexico it is badged as an Expedition Max because of confusion with the Canada-sold Acura EL, which was replaced in 2005 by the Acura CSX (the Expedition Max name continues to be used in Canada). At first it was supposed to be called the Everest but Ford changed their minds at the last minute.[45] However, Ford now uses the Everest name for its SUVs in Asia. As with the standard size Expedition, the EL/Max version continued to have the same features from the 2007 to 2011 model year, but for the 2012 model year it added a cargo organizer as an exclusive feature.[46]

The EL/Max replaced the discontinued Excursion and is expected to compete more effectively with the Chevrolet Suburban/GMC Yukon XL. While both GM and Ford vehicles are similar in size (as both Suburban/Yukon XL 1500s and EL vehicles are packaged as half-tons), there is a difference in the pricing range, as the sale price for the EL model Expedition is lower than the sale price of the Suburban/Yukon XL's. Another difference is that while Chevrolet and GMC offer different engine sizes for their Suburban/Yukon XL models (5.3L, 6.0L and 6.2L), the EL/Max only comes with a 5.4L/V8 engine, just like its standard-size sibling and does not have a 3/4 ton version like the Suburban/Yukon XL has.

Outside North America, including the U.S. territories of Puerto Rico, U.S. Virgin Islands, and Guam, the Expedition EL is also imported to and sold in the Middle East and the Philippines, where in the latter the EL version is the only type of Expedition that is imported and sold there. Coincidentally, the Philippines is also where Ford also sells the Everest SUV.

The Expedition EL is about 14.8 in (39 cm) longer than the standard Expedition for a total of approximately 222 in (18.5 feet or 563 cm), and has a 131 in (333 cm) wheelbase, producing 24 ft³ of additional cargo space over the standard 119 in (302 cm) wheelbase model. The EL/Max versions also carries the same updated (2007–present) features as noted above, save for the Eddie Bauer version (18" machine-aluminum wheels). And while they are larger in size, its maximum towing capacity is 8,900 lb (4,000 kg) on the 4x2 version and 8,700 lb (3,900 kg) on the 4×4 version, about 300 lb (140 kg) short of the regular sized Expedition. They also received a 5-star rating from the NHTSA.[47] The Expedition EL was also ranked 9th among the top 15 "Best Family Haulers", according to a June 2009 consumers favorite survey conducted by Edmunds.[48]

Just like the standard sized Expedition, the Expedition EL originally came in 4 trim lines: XLT, Eddie Bauer, Limited and the King Ranch series during the 2007-2010 model year. After the 2011 model year was introduced, the trims expanded to 5, with the XLT and XLT Premium levels replacing the Eddie Bauer level and the newly designated standard XL entry level taking the XLT's place. The XL, XL Premium and XL Sport levels were dropped after the 2012 model year. The Expedition EL can be distinguished by its longer rear-quarter windows and the aft wheel well trim not cutting into the rear passenger doors.

Availability

The standard size Expedition are sold in the United States, Canada, Mexico, the U.S. territories of Puerto Rico, American Samoa, the CMNI, U.S. Virgin Islands, and Guam, the Philippines, the Middle East, Central America, the Caribbean, South America (except Argentina, Brazil and Venezuela), Asia (Cambodia, Laos, Mongolia and South Korea), Africa (Algeria, Angola, Cape Verde, Egypt, Gabon, Ghana, Libya, Madagascar, Morocco, Nigeria and Senegal), and Europe (Armenia, Kazakhstan, and Kyrgyzstan).[49]

For the Expedition EL/Max, all five versions (XL, XLT/Eddie Bauer, XLT Platinum, Limited and King Ranch) are available in the United States. From the 2007 to 2010 model years, The EL/Max level trims were limited to only 3 versions for Canada and The Middle East, two for Mexico, and one for the Philippines. Canada's Expedition Max offered the Eddie Bauer, Limited and King Ranch trims, Mexico's Expedition Max in Limited and King Ranch trims, and the Middle East's EL level trims in XLT, Eddie Bauer and Limited. The Philippines' lone Expedition EL level trim was the Eddie Bauer model from 2007 to 2010. After the 2011 model year Ford made changes in the international exportation of the EL/Max trims. As a result of the changes, the Limited trim became the only version available in Canada and Mexico as Eddie Bauer (in Canada) and King Ranch trims (in both Canada and Mexico) were discontinued, while the Philippines and the Middle East replaced the Eddie Bauer with the XLT trim. The Middle East also started to get all of the 5 US level base trims, including the new XL trims that took the XLT's place and the King Ranch trim.

Four-wheel drive system

Selectable automatic Control Trac four-wheel drive designed by BorgWarner is standard on all 4WD Expeditions. There are four modes: Two High mode, Auto mode, Four High mode and Four Low mode. Each mode can be selected via a rotary control dial on the dash.

The Expedition's system uses a two-speed dual range BorgWarner transfer gearbox with a software controlled variable intelligent locking center multi-disc differential. The four-wheel drive system does not use a planetary or bevel geared center differential, which are typically found in permanent four-wheel drive systems where torque is permanently supplied to all four wheels.

Below is the operational behavior mode-by-mode for the current version of ControlTrac four-wheel drive used in the third generation (2007–present) Expedition.

Note that older versions still work in similar fashion, but will not be equipped with default off road program and may not be equipped with AdvanceTrac.

Selectable Automatic ControlTrac Four-Wheel Drive[50]
Mode Drive type Operation
Two High (2H) Rear-wheel drive Torque is routed to the rear-wheels only, with high range gearing. Imitates rear-wheel drive and is more economical for on road driving.
Auto (4A) All-wheel drive
(unlocked, variable)
Software does all the work. All 100 percent of the engine’s torque is sent rearward until traction loss is anticipated or detected. The intelligent locking center multi-disc differential can "torque bias" redirecting any percentage of supplied torque to the front drive wheels while still allowing the front and rear drive shafts to turn at different rotational speeds. If severe traction loss is detected at the rear-wheels, up to 100 percent of the engine’s torque can be sent forward to the front-wheels. High range gearing is used. For use in all-weather on road (dry, wet or slippery pavement) conditions or light off road conditions.
Four High (4H) All-wheel drive
(locked)
The intelligent locking center multi-disc differential is locked providing a permanent 50:50 torque distribution.[51] The front and rear drive shafts are mechanically locked together forcing them to turn together with absolute zero rotational speed difference. Front drive wheels pull at the same rate the rear drive wheels push. High range gearing is used. Not for use on pavement, only for off road conditions. If Four High mode is used on pavement, torque windup and drivetrain binding can occur resulting in catastrophic driveline failure.
Four Low (4L) All-wheel drive
(locked)
Similar to Four High mode in operation, the permanent 50:50 torque distribution is maintained; however, low range off road reduction gearing is engaged. A default off road program is automatically selected and remaps (reprograms) the electronic throttle control, traction control system (engine control), and turns off AdvanceTrac’s electronic stability control and roll stability control safety systems for off road use.[15][52] Four-wheel electronic traction control (brake control) continues to function as normal.[15] Not for use on pavement, only for off road conditions. If Four Low mode is used on pavement, torque windup and drivetrain binding can occur resulting in catastrophic driveline failure.

4WD Expeditions come with standard dual front frame-mounted closed-loop recovery hooks and available off-road under body protection. Steel plates are placed over vital areas with a composite shield for the fuel tank. Expedition 4x4s are tested alongside the F-150 and Super Duty trucks at Ford’s California and Arizona proving grounds. Expedition is put through the same durability tests and evaluations to meet the same durability standards as its pickup truck brethren.[53]

Traction Control

Ford Expeditions, whether they are rear-wheel drive or all-wheel drive come from the factory with conventional open-type differentials with a choice of axle ratios. Traction control systems, both mechanical and electronic, were offered as options if needed. Only until recently has traction assist become standard on all Expeditions.

Mechanical traction control (1997–2006)

Both first and second generation Ford Expeditions (UN93 and U222) were offered with an optional Traction-Lok rear limited-slip differential (LSD) with a choice of axle ratios. When rear-wheel slip (spin) was detected, a simple clutch pack inside the differential would engage to transfer torque between the rear-wheels to whichever rear-wheel had better traction. The clutch packs inside the LSD tend to be weak, and they will wear over time, gradually losing their ability to transfer torque. Eventually, if they are not replaced, the LSD will function like an open-type differential.[54] Furthermore, the front differential on four-wheel drive models was always an open-type differential, with no way to control wayward torque flow caused by traction loss. Both these problems were remedied with the arrival of AdvanceTrac electronic stability control for the 2003 model year. 2006 was the last model year for the Traction-Lok limited-slip differential.

Electronic traction control (2003–present)

AdvanceTrac electronic stability control was introduced for the 2003 model year as an optional extra on the second generation Ford Expedition (U222). Bundled with the electronic stability control system is four-wheel electronic traction control (functions at all wheels) for Expeditions with four-wheel drive.[15] Two-wheel drive Expeditions only receive two-wheel electronic traction control (functions at rear wheels). AdvanceTrac was made standard equipment on all third generation Expeditions (U324).

The traction control system uses the Expedition's four-wheel, four-sensor, four-channel anti-lock braking system (ABS) to apply and release the disc brakes on any drive wheel that has lost traction. The ABS brakes aggressively clamp down on the slipping drive wheel or wheels, "brake locking" the differential, which can transfer up to 100 percent of supplied torque to the opposing drive wheel with better traction. By ABS "brake locking" both the front and rear differentials, the traction control system can simulate front and rear differential locks allowing a four-wheel drive Expedition to keep moving, even if only one wheel has traction, no matter which wheel it is. The system will also allow the Expedition to keep moving even if two of its drive wheels (one front, one rear) are airborne, completely off the ground.[16][15]

Using the ABS brakes rather than mechanical limited-slip or locking devices inside the axle differentials gives quicker response, more seamless performance, and enhanced durability.[16][15]

Towing capability

When first introduced in 1996, the Expedition competed directly with both the Chevrolet Tahoe and GMC Yukon in the full-size half-ton SUV towing segment. New competitors to the towing segment emerged soon thereafter which include the Dodge Durango (which was discontinued in 2009, but reintroduced in 2011), Nissan Armada and Toyota Sequoia. Product research conducted by Ford indicated that 92 percent of Expedition owners use the SUV for vacations. Some 60 percent use it to transport outdoor sports equipment, while 40 percent of Expedition owners use the vehicle for towing.[55] The half-ton Expedition EL/Max competes with the half-ton Chevrolet Suburban 1500 and GMC Yukon XL 1500 in the towing segment.

Since its introduction, the Expedition’s braked trailer towing capacity has grown from 8,100 lbs (3,674 kg or 4.05 tons) to a current rating of 9,200 lbs (4,173 kg or 4.6 tons) when properly equipped. The list of towing features is also ever growing. Towing features common to all generations of the Expedition include: smallest possible turning radius for increased trailer maneuverability, large side view mirrors to improve rearward visibility, rearward-facing lane departure indicators which are helpful to other motorist when the Expedition is towing a long trailer providing added visual safety, heavy-duty flashers,[56] heavy-duty large robust disc brakes to withstand prolonged braking while towing and an available heavy-duty trailer tow package which includes necessary additions for heavy-duty towing.

Heavy-duty trailer tow package

Expeditions equipped with the heavy-duty trailer tow package are prepped and readied for towing at the factory. The package includes a heavy-duty V-5 rated Class IV (Class 4) trailer hitch with weight distribution capability, heavy-duty radiator, heavy-duty auxiliary transmission fluid cooler, hitch mounted 4 and 7-pin trailer electrics connector and factory prewiring for an electronic trailer brake controller module. The brake controller wiring harness is located under the dash on the driver’s side for easy installment of the brake controller module.

Expeditions are also offered with an adaptive pneumatic air-ride suspension system with self leveling, payload leveling and trailer load leveling capability. The electronically controlled pneumatic suspension can automatically detect when a heavy trailer is coupled, such as a travel trailer, and level the load. Additional sensors placed on the left and right sides of the SUV also monitor and compensate for any listing caused by improper cargo loading. This keeps the Expedition running straight and level while towing, and at night helps to keep the Expedition’s headlamps from blinding oncoming traffic.

As of the 2010 model year, the Expedition received trailer sway control (TSC) as standard equipment. TSC builds on the AdvanceTrac electronic stability control system to detect trailer oscillations and corrects it via asymmetrical breaking and reducing engine power until the Expedition and its trailer are both back under control.[57]

For the 2013 model year, an electronic trailer brake controller module is now equipped at the factory, included with the heavy-duty trailer tow package. The trailer brake controller is fully integrated into the Expedition’s four-wheel, four-sensor, four-channel anti-lock braking system (ABS), and trailer sway control (TSC).[58]

Special Service Vehicle

A 2nd-Generation Ford Expedition Special Service Vehicle used by the Pennsylvania State Police.

To compete with large police SUVs that are sold by other automobile companies, primarily the Chevrolet Suburban, Ford has made a special version of the Expedition available to law enforcement agencies, fire departments, and EMS agencies. Ford calls it the Expedition Special Service Vehicle (SSV). The only differences between the standard Expedition and the Special Service Vehicle Expedition are provisions for emergency services related equipment such as radios, lightbars and sirens. There are also options designated fleet only such as custom two-tone paint arrangements that are available to the Expedition Special Service Vehicle The Ford Expedition is a popular choice among other Full-Size SUVs by border patrol, and other all-terrain law enforcement because of its overall better reliability compared to other rivals, like the Chevrolet Tahoe. [59][60][61][62]

Funkmaster Flex edition
