The Acura MDX, or Honda MDX as known in Japan and Australia (only the first generation was imported), is a mid-size luxury crossover SUV produced by the Japanese automaker Acura since the 2000. The MDX was the first crossover SUV to have third-row seating. The alphanumeric moniker stands for "Multi-Dimensional luxury". It was introduced as a 2001 model, replacing the slow-selling U.S.-only body-on-frame SLX, based on the Isuzu Trooper. In Japan, it filled a gap when the Honda Horizon (also based on the Trooper) was discontinued in 1999. In 2003, the Honda MDX went on sale in Japan and Australia. For 2009, Acura added a crossover to slot above the MDX, called the ZDX, similar in appearance to the BMW X6.

Derived from Honda's Global mid-size platform which underpins cars like the Honda Accord, Acura TL, TSX and Odyssey, it is powered by a J35A3 3.5 L SOHC 24 valve V6 with VTEC. 2001-2002 3.5 V6 models produce 240 hp (180 kW) and 245 lb·ft (332 N·m) of torque from 3000 to 5000 rpm. 2003-2006 3471 cc (3.5 in x 3.6 in) model engine produces 265 hp (198 kW) and 253 lb·ft (343 N·m) . Curb weight is 4,451 lb (2,019 kg), with a 106.3 in (2,700 mm) wheelbase and 8 in (200 mm) of ground clearance. The cargo floor can flip up to provide two additional seats. The vehicle is designed to hold 7 passengers, but the third row seats are small.It is related to the honda odyssey mini van.
The vehicle features an automatic four wheel drive system (named VTM-4) that engages during off the line acceleration as well as when wheel slippage is detected. Additionally, the system offers a lock mode which can be activated and operated at low speeds and provides permanent 4wd and the equivalent of a locked rear differential; designed for climbing steep hills and getting out of stuck situations. To reduce drivetrain noise and increase fuel efficiency, the system runs as front wheel drive during normal cruising. The VTM-4 AWD system in the MDX is identical to the VTM-4 systems in the Honda Pilot and Honda Ridgeline. It is different than the real time AWD system in the Honda CR-V in that it can lock and it attempts to predict when traction will be lost and apply power to all four wheels before slippage occurs (by monitoring throttle inputs). The Honda CR-V system waits for slippage to occur and then sends power back.
2003 and later models use a revised 5-speed automatic transmission. The 2001 and 2002 models use a 5 speed automatic transmission which suffered a significant numbers of transmission problems that were similar to the problems with the Acura CL and TL. However, they did not get the benefit of the free extended warranty that the Acura CL and TL received, though the company often paid for the required parts. The 2003 and later models also received a number of structural and suspension modifications to help improve ride and handling. As of the Summer 2010 edition, Consumer Reports shows a drastic increase in reliability in the "Transmission, Major" category, going from far below average reliability on 01-03 models to above and well above average reliability on 04+ models. However, according to forum MDXers.org a significant portion of 05-06 owners have complained of harsh shifting and Acura has begun issuing recall letters in order to re-flash the computer which change transmission shift points and torque converter settings. Owners are reporting smoother shifting but some loss of MPG due to using lower gears.
The navigation system and DVD entertainment system options were mutually exclusive in the 2002 model. Both could be ordered at the same time since the 2003 model. The navigation option comes with a rear view video camera since the 2003 model. Since 2005 the navigation system featured information from Zagat about restaurants and other points of interest. The 2003 model was rated as Ultra Low Emission Vehicle. The United States Environmental Protection Agency estimates 23 mpg-US (10 L/100 km; 28 mpg-imp) highway and 17 mpg-US (14 L/100 km; 20 mpg-imp) city.
The 2001-2006 MDXs sometimes offered better fuel economy than competing SUVs and crossovers of similar size, interior volume, and weight (such as the Ford Explorer and BMW X5 for example) due to the front-wheel drive basis, at the expense of handling and road feel.
In the 2003 model, the engine was improved to produce 20 hp (15 kW) more power than the 2002 model and wheel designs were updated. The 2004 model received an additional 5 hp (4 kW). The 2004 model is credited for a top speed of 137mph, and a 0-60 time of 7.1 seconds. The 2004 model features dual tail pipes instead of the single pipe in earlier models, side curtain airbags, new head lights and tail lights, and new wheels. Some chrome trimmings on the 2004 model use matte finish to distinguish from the polished shiny finish on earlier models. Little changed for the MDX during the 2006 model year with a few minor revisions to the vehicle's chrome and faux wood interior trim which could now be had with a dark grey wood (as opposed to reddish wood on earlier models), and also a black dash and steering wheel in tan interiors.

On April 11, 2006, Acura unveiled the 2007 Acura MD-X Concept during the New York International Auto Show, showing to the public an indication about the exterior styling of the upcoming completely redesigned MDX. The second-generation MDX was released on October 17, 2006 in the U.S.
The second generation model's body has a wider track and longer wheelbase than the previous MDX, but visibility to the rear has worsened from the prior generation. The redesigned Acura MDX's unit-body was engineered with Honda's Advanced Compatibility Engineering (ACE) body structure designed to absorb energy from a collision. The suspension was tuned at Germany's Nürburgring race track. The engine was upgraded to a 3.7 liter V6 tuned for 300 hp (224 kW) at 6,000 rpm and 270 lb·ft (366 N·m) of torque at 5,000 rpm. It accelerates from 0-60 mph in 6.5 seconds and is estimated by the EPA to consume 16 miles per US gallon (15 L/100 km; 19 mpg-imp) in the city and 21 miles per US gallon (11 L/100 km; 25 mpg-imp) on the highway. It is one of the most powerful engines Honda has produced to date. The "VTM-4" all-wheel drive system on the previous generation was replaced by the new SH-AWD "Super Handling All-Wheel Drive" previously debuted on the 2005 Acura RL. This AWD system is one of the most advanced in its class, featuring an active rear differential often found on high performance cars. The MDX is able to tow 5,000 lb (2,300 kg).
Like all Acuras, the MDX comes with a high level of standard equipment, including a power moonroof, leather interior, and high intensity discharge (Xenon) low beam headlights. For the 2007 through 2009 model years, three option packages were available: Sport, Technology and Entertainment.
- The Technology Package includes the Acura/Alpine DVD-based satellite GPS navigation system with AcuraLink satellite communications with real-time traffic reporting (XM NavTraffic), a 410-watt Acura/ELS DTS Surround audio system with XM Satellite Radio, rearview camera, and a remote powered liftgate, operated either from the key's remote, inside the car or directly from the lift gate.
- The Sport Package featured active suspension dampers (co-developed by Honda and Beijing West Industries that dynamically improves handling according to road conditions with a button in the center stack to switch to Sport/Comfort modes. This Comfort/Sport mode uses magneto rheological dampers, which change their characteristics when a magnetic field is introduced (usually in milliseconds). The Sport package also includes unique 5-spoke aluminum-alloy wheels, perforated leather seats and the items in the Technology package.
- The Entertainment Package offers a flip-down 9-inch (230 mm) LCD screen with 2 wireless Dolby Digital headphones, second-row heated outboard seats, and a unique center-stack silver trim. The Entertainment Package is only available on Sport or Technology Package models as compared to the 1st Generation MDX where the Entertainment Package was available as a standalone package on Touring Models.
All Canadian Acura MDX models, aside from the heated front seats, also get the second-row heated outboard seats as standard equipment as well. A feature unique to Canadian MDX models are headlight washers. In terms of packages, Canadian MDX models get only two: Technology and Elite. The Technology package corresponds essentially to the US model's Technology package while the Elite package is an amalgamation of the US model's Sport and Entertainment packages. However, AcuraLink real-time traffic reporting through XM NavTraffic is unavailable for Canadian MDX models.
Like the first generation model, the new generation is manufactured exclusively by Honda of Canada Manufacturing Ltd. in Alliston, Ontario, Canada. But along with the 2007 RDX, the new MDX was the first Acura model to pass the Acura Quality Line, a special quality control and verification process separate from the other Honda vehicles.
For 2008 the MDX received a new auto-dimming rearview mirror. The 2009 MDX had added more upgrades to the navigation system and there are two new colors added. The power tailgate, previously available only with the Entertainment package, is now included with Technology and Sport packages.
The 2010 MDX got a facelift, adopting Acura's new "Power Plenum" grille that debuted on its 2009 model year sedans. The most important upgrades to the 2010 model are a new 6-speed SportShift automatic transmission. An Advance package is now available that includes Adaptive Cruise Control, blind spot monitor, Active Damper Suspension, circle-see assist, Tire Pressure Activation, Blind Spot Attention, 19 inch wheels and tires, Ventilated seats and paddle shifters. Non-navigation equipped MDX models now have a rear view camera monitor located in the rear view mirror.
The redesigned MDX overtook the TL as Acura's top seller in the United States. In the 2012 model year, 50,854 units of the MDX were sold, making it the nameplate's top seller, while the Acura TL at 33,572 units was second. It is also Acura's best-selling vehicle in Canada since the vehicle was redesigned.

The 2014 MDX Prototype was unveiled at the 2013 North American International Auto Show, the production version was revealed at the New York Auto Show. Production began on May 2, 2013; vehicle assembly shifted from Ontario, Canada to Lincoln, Alabama. US sales began on June 20.
The MDX is now powered by a 3.5-liter direct injected Earth Dreams V6 with Variable Cylinder Management. EPA-estimated fuel economy is improved with all-wheel drive (SH-AWD) models rated at 18/27/21 mpg (city/highway/combined) and FWD models rated at 20/28/23 mpg.
The interior reduced button clutter by adding a 7-inch touchscreen with haptic feedback, an additional 8-inch screen is also standard. To reduce interior noise an acoustic (acoustic PVB) windshield, acoustic front door glass and thicker rear glass are used as well as triple sealed door openings. Advance package models include further noise reduction using a thicker carpet base layer and front fender liners. The seating H-point has been reduced and the steering gear ratio is 9% quicker for a more sporty feel. The MDX rides lower reducing its center of gravity.
According to Acura the exterior is more aerodynamic reducing drag by 16% with the new model lapping Nürburgring 8 seconds faster than its predecessor. The headlights are Acura's Jewel Eye LED Headlights (first introduced on the RLX). Each headlamp uses five separate LED sources with three used for low-beam lighting and two for high-beam lighting. LED bumper mounted fog lamps are offered as a dealer installed option.
Structure rigidity is improved and weight reduced through increased use of high-strength steel. Overall, 64% of the total vehicle body mass is high strength steel (HSS), aluminum and magnesium. HSS makes up 59% of vehicle body mass; 1,500 MPa yield strength steel makes up 7%. A single ring-like hot stamped HSS component reinforces the A-pillar, roof rail, B-pillar, and lower floor rail encircling the front doors for improved crash protection. Acura states that after conducting a simulated IIHS 25% small offset frontal crash test the front doors will open with normal force.
In terms of safety the MDX adds a standard driver's knee airbag, optional Lane Keeping Assist System and Collision Mitigation Braking System. The Adaptive Cruise Control now comes with stop and go functionality.
Unlike in previous model years, the navigation system now prevents the driver and front seat passenger from entering destinations manually while the vehicle is in motion. Destinations can be entered only by voice control while in motion. Each element of the address (street, city, house number) must be entered in a separate operation, and voice control is not available to the front seat passenger because the microphone is directional, and pointed at the driver.
On August 19, 2013, the 2014 MDX was in a comparison test by Edmunds with the 2013 Lexus RX and 2014 Infiniti QX60. The MDX beat out its competition with the RX in 3rd and QX60 in 2nd. Edmunds said "The 2014 Acura MDX just had too many 'bests' to be denied: the best handling, the best front seats, the quickest acceleration, the largest max cargo capacity and the potential for the best fuel economy. And without question, it's the driver's SUV of the trio."
The new MDX is currently outselling its predecessors, setting all-time monthly sales records.
