The BMW M5 is a high performance version of the BMW 5-Series executive car built by the Motorsport division of BMW. First introduced at the Amsterdam Motor Show in 1984, the first incarnation of the M5 was hand-built utilizing the 535i chassis and a modified BMW M1 engine, being the fastest production sedan in the world at the time of its introduction. Subsequent iterations of the M5 have been built from each generation of the 5-Series platform, including the E34, E39, E60/E61, and most recently, F10, with the first orders to be delivered in late 2011.

Due to the longevity of its nameplate and undisputed position at the top of BMW's midsize lineup, the M5 remains one of the best known sport sedans, despite competition from Mercedes-AMG and Audi quattro GmbH.

History of development

The M5 was preceded in 1980 by the M535i, the third road-going automobile to emerge from the BMW Motorsport workshop. While the BMW 3.0 CSL and M1 had been limited-production, purpose-built sports cars, the M535i was a reworked 5-series sedan fitted with the BMW M30B35 engine.

Successor	E34 M5

The first BMW M5, based on the E28 5 Series, made its debut at Amsterdam Motor Show in February 1984. It was the product of demand for an automobile with the carrying capacity of a saloon (sedan), but the overall performance of a sports car. It utilized the 535i chassis and an evolution of the engine from the BMW M1. At its launch, the E28 M5 was the fastest production sedan in the world.

The first generation M5 was hand-built in Preußenstrasse/Munich prior to the 1986 Motorsport factory summer vacation. Thereafter, M5 production was moved to Daimlerstraße in Garching where the remainder were built by hand. In May 1987, the keys to the 1000th car were presented to Mr. and Mrs. Krampertz from Eichenau near Munich by Wolfgang Peter Flohr, the director of BMW Motorsport GmbH. It is worth noting that production of the M5 continued until November 1988, well after production of the E28 chassis ended in Germany in December 1987.

The M5 was produced in four different versions based on intended export locations. These were the left-hand drive (LHD) Euro spec, the right-hand drive (RHD) UK spec, the LHD North American (NA) spec for the United States and Canada, and the RHD South African (ZA) spec.

The LHD, RHD Euro Spec M5s and the ZA spec M5s had the M88/3 powerplant which delivered 286 PS (210 kW; 282 hp) whereas the North American 1988 M5 was equipped with a variant of the M88/3 called the S38 B35 which was equipped with a catalytic converter, which, combined with slightly lower compression of 9.8:1 versus 10.5:1 for the M88/3 reduced the power output to 256 hp (191 kW; 260 PS). The S38 also differed from the M88/3 in that it had a dual-row timing chain as compared to the M88/3's single row timing chain. The S38 B35 was used in the NA-Spec E28 M5 and E24 M6. Late production catalyst equipped versions (117 examples) of the European M635CSi were also equipped with the S38 B35. Initially 500 were to be made for the US Market, BMW later increased production to as many as 1,370 units for the US and Canadian markets, although the generally accepted figure is 1,244 units sold.

The North American spec models are unique, in that technically they were all finished in Schwarz (Black) with Natur (Tan) interiors. The otherwise virtually identical Canadian spec M5s were also available with Black interiors as an option, however a limited number of US Models were also equipped with Black interiors

Rear view of US-spec M5

United States Vehicle Identification Numbers (VINs) range from 2791000-2792000 and 2875000-2875320. Car # 2791000 is not known to have been built, and not all VINs are known to have been used. The first few cars built in November and December 1986 were issued Federal compliance labels showing a 1/87 build date. As has been speculated earlier, physical confirmation of the VIN of the United States M5 kept in BMW North America's Mobile Tradition collection is a 287 series car, a later 1987 build date car.

While every North American spec E28 M5 was a 1988 model year car, production of North American specification M5s commenced in November 1986 and ended in November 1987. Excepting 96 units that were assembled in kit form at BMW's Plant in Rosslyn, South Africa, all E28 M5s were assembled by hand at BMW Motorsport in Garching, Germany.

With a total production of 2,191 units, the E28 M5 remains among the rarest regular production BMW Motorsport cars - after the BMW M1 (456 units), BMW E34 M5 Touring (891 units), and the BMW 850CSi (1510 units).

Specification

• (European) - 286 PS (210 kW; 282 hp) M88/3 Engine with 10.5:1 Compression. European-Spec M5s were available with a myriad of options unavailable on USA-Spec M5s such as Water Buffalo leather and a Glass Moonroof. LHD cars were equipped with 185TR390 Metric Wheels made by Mahle with 220-55VR390 Michelin TRX tires. RHD Cars were equipped with 16x7.5 BBS wheels with 225-50VR16 Tires - these wheels were not shared with any other model. Air Conditioning was standard on UK Supplied M5s and optional on LHD M5s. It is also notable that very early European-Spec LHD M5s had VINs that started with "WBA" instead of the "WBS" designation to indicate BMW Motorsport. it is estimated that no more than 15 M5s were produced with a "WBA" VIN. European-Spec M5s were available in various colors and with or without leather upholstery. At least one UK specification car is known to have been produced with comfort seats.

• (USA/Canada) - (256 bhp (191 kW) in USA/Canada units) S38B35 Engine with 9.8:1 Compression. All US-Specification M5s were comprehensively optioned. Leather Door Panels, Leather Center Console, Full Trunk Carpeting, Air Conditioning, Power Windows, Power Sunroof, Power Seats, Cruise Control, On-Board Computer, Central Locking and Shadowline Trim were standard. The only option on a US-Specification M5 was electrically heated front seats which were standard equipment on Canadian-Market cars. All North American specification M5s were finished in "Schwarz" or Jet Black. Officially US Specification cars were only available with Natur (Tan) leather interiors, however Black was offered in Canada and a handful of US-Bound cars were built with black interiors.

Performance

At the time of sale, BMW quoted the following 0-60 mph times to give the impression that the E28 M5 did not outperform the more expensive and heavier E24 M635csi.

M88/3 engine from 1985 E28 M5

• (Euro) - 282 PS (210 kW) - 0-60 mph - 6.2 s - Top Speed: 153 mph (246 km/h)
• (USA) - 256 hp (191 kW) - 0-60 mph - 6.5 s - Top Speed: 148 mph (238 km/h)

Tuners

• Whilst BMW Motorsport did not build any special versions of the E28 M5, the German tuner Hartge produced the Hartge H35S-24, a 330 PS (243 kW; 325 bhp) version of the E28 M5. Main modifications over and above the standard E28 M5 were revised cams, a modified exhaust, modified Bosch Motronic ECU programming, and a revised (and lowered) suspension setup.
• Alpina limited their tuning efforts to the older M30 engine powered models. The Alpina B7 Turbo produced 250 kW (340 PS; 335 bhp) with 0-60 mph times of 4.7 sec and a top speed of 270 km/h (168 mph).

The E34 M5 is a continuation of BMW's M5 series, based on the 5-series. It was produced from 1988 to 1995, although sales in North America started in 1990 and ended in 1993. It was produced at BMW M GmbH in Garching, Germany and like the previous M5, was entirely hand-built. It utilized the 535i chassis which was produced at BMW's Dingolfing plant. Assembly was done either by a single M employee or a team of M employees and generally took about two weeks. It is rumored that the test drivers of the E34 M5 could determine who or what team made each specific M5, due to characteristic quirks of the handbuilt nature of the E34 M5. The engines were also built by hand by BMW M technicians. All of the E34 M5 powerplants were built to 5% of advertised output.

The early E34 M5 used an evolution of the 24-valve straight-6 found in the E28 M5 and E24 M635CSi/M6. The engine was designated S38B36, with a bore of 93.4 mm (3.677 in) and stroke of 86 mm (3.386 in) for a total capacity of 3,535 cc (215.7 cu in). The added stroke is due to a new forged steel crankshaft, though the camshafts were also changed. Compression ratio was up slightly (10:1 versus 9.8:1). Other adjustments made included an electronically controlled butterfly valve in the intake plenum, which provided better low rpm and mid-range power. The engine also featured an improved flywheel, Bosch Motronic fuel injection, equal length stainless steel exhaust headers, and three way ceramic catalysts. Originally it had a displacement of 3.6 litres, and produced 232 kW (315 PS; 311 bhp), and 360 N⋅m (266 lbf⋅ft) at 4750 rpm. Cars sold in North America and Switzerland, due to a different catalytic converter, produced 229 kW (311 PS; 307 bhp).

In second half of 1991, the engine displacement was increased to 3.8 litres with the S38B38, except in North America and South Africa, which continued with the 3.5 litre engine, because that one had emission controls fitted. Power was now increased to 250 kW (340 PS; 335 bhp). Also in 1992, a five-door Touring version (estate/wagon) was introduced in LHD form, with 891 cars made.

The E34 M5 Touring was the world's fastest wagon when it was introduced. It was BMW M Division's first wagon, but at the same time the last hand built M car made. Its 3.8L straight six was also the largest displacement six-cylinder engine of BMW's modern era. While none of these wagons were imported to North America, several have been imported since 1995 and have become a cult car among BMW Touring Enthusiasts. Only with the advent of the Audi/ Porsche RS2 Avant would the M5 Touring be challenged by another Q-ship station wagon.

The M5 came with an unusual wheel design. From 1988-1992 the M5 featured the M-System wheels. These wheels were 8Jx17J, but came with directional bolted-on wheel covers. Under the cover was a black 5-spoke alloy wheel. The press was critical of the design, often claiming it gave the M5 the appearance of having "white-wall" tires. In 1992 BMW changed the design and a new cover was produced – the M-System II. The original intent of the M-System cover was to direct more air to the brake assembly to increase cooling. The cover actually integrated a fin assembly behind the cover. The M-System II covers, known as the "throwing stars" did not have as much capability to direct air to the brake assemblies. In May 1994, the M5 came with M Parallel wheels that did away with the cover.

Special versions

There were four special editions of the E34 M5. The Cecotto, Winkelhock and 20 Jahre editions which were offered as LHD Euro specification models while the RHD UK Limited edition was only sold in the United Kingdom.

E34 M5 Cecotto Edition

In 1991, BMW asked two race drivers to design their "ideal" version of the E34 M5. Johnny Cecotto was one of the drivers and he wanted a host of luxury items fitted on the M5. Including Nappa leather trim for the steering wheel and heated seats. A total of 22 Cecotto E34 M5s were produced with options of having either Lagoon Green metallic (266) and Mauritius Blue metallic paint (287).

E34 M5 Winkelhock Edition

The other racing driver was touring car ace Joachim Winkelhock. He wanted a lightweight E34 M5 and so some luxury items were removed. His ideal lightweight version M5 featured a smaller battery and the US-spec 81L fuel tank as well as reduced sound deadening and the deletion of some non essential interior items such as rear head rests and vanity mirrors. Recaro front seats and a suede 385 mm M-Technic II steering wheel, shift knob & parking brake lever. The seat design, suede-covered appointments & red seatbelts were similar to those on the Sport Evo E30 M3. A total of 51 Winkelhock E34 M5s were produced with the options of having Jet Black (668) with contrasting lower body panels in Sterling Silver metallic paint (244).

E34 M5 20 Jahre Motorsport Edition

To celebrate BMW Motorsport 20th anniversary, BMW had built 20 specially equipped Euro-spec M5s in late 1992. These, based on the 3.8 L engine were only in Mugello Red (274) and had a number of aesthetic trim upgrades such as carbon fiber dash panels and special rear view mirrors. Unique seat center & door trim fabric was matched with Alcantara. Alcantara was also used on the steering wheel, shift lever & parking brake lever. Red seatbelts with "BMW Motorsport" were also included.

E34 M5 UK Limited Edition

To commemorate the end of right-hand drive E34 M5 production, 50 examples of the E34 M5 Limited Edition were assembled between March and June 1995 in one of two unique color and trim combinations: Rosso Red metallic (369) with a Champagne extended leather interior and natural poplar wood trim (15 built) or Orinoco metallic (406) with a Bicolor Petrol and Mint extended leather interior and graphite bird's-eye maple wood trim (35 built). Each E34 M5 Limited Edition is equipped with the three-spoke sport steering wheel, Shadowline trim, power sunroof, power front seats, headlight washers and manual air conditioning. A numbered plaque appears on the center console. (Source: bmwmregistry)

Additionally, 20 M5 Touring models were assembled for distribution in Italy. These were finished in either Sterling Silver over Marine Blue leather, or British Racing Green over Tobacco leather. All were made in 1995. It is debated as to whether or not these cars constitute a true special edition as they were ordered directly by a group of Italian BMW dealers.

These are not to be confused with the Alpina B10 E34 models which are manufactured by Alpina although there are performance similarities but there are significant differences in approach.

Motorsport

The M5 has never been a popular choice for motorsport due to its size and weight. However, VDS Racing Adventures have used an E34 M5 in endurance racing, where weight and nimbleness is less important than in sprint racing. The car features many one-off components, including a wide-arch fibreglass bodykit, but the engine is based on the 3.8-litre S38 straight-six and is almost standard, producing approximately 350 PS (260 kW; 350 hp). It has also raced in the Belgium Belcar Championship, where it was runner up in 2001.

An E34 M5 was raced in the Australian 1992 Bathurst 12 Hour Production Car endurance race, placing 2nd overall, and 1st in its class. It was driven by former F1 champion Alan Jones, Neville Crichton, and BMW Touring car driver Tony Longhurst.

2002 BMW M5 Interior (US spec)

2002 BMW M5 5.0 S62 Motor

Unlike its predecessors, the E39 M5 was not handbuilt at the BMW M GmbH factory; in order to increase production, it was produced on the same assembly line as the normal E39 5-series at the Dingolfing factory in Germany. In fact, the E39 M5 was almost not built at all; BMW believed that the 210 kW (286 PS; 282 bhp) 540i was powerful enough, but when Jaguar released the 272 kW (370 PS; 365 bhp) XJR, and Mercedes-Benz introduced the W210 E55, which had over 260 kW (354 PS; 349 bhp) BMW responded to the competition with a 294 kW (400 PS; 394 bhp) M5.

Introduced in 1998 at the Geneva Motor Show, production did not begin until late October of that year. A total of 20,482 E39 M5s were made from 1999 to 2003. BMW M produced three versions of the E39 M5, the European LHD and RHD versions, and the North American specification version.

The E39 M5 had a highly tuned V8 engine based on the M62 engine called the S62, which displaced 4.9 litres and produced 294 kW (400 PS; 394 bhp). The engine featured a 7,000 rpm redline, Double-VANOS, which varies the intake and exhaust valves timings for both cylinder banks, and individual throttle butterflies for each of the cylinders, allowing for a much faster engine response time.

All E39 M5s were equipped with a Getrag Type D six-speed manual transmission which provided the following gearing ratios:

• 1st gear: 4.23
• 2nd gear: 2.53
• 3rd gear: 1.67
• 4th gear: 1.23
• 5th gear: 1.00
• 6th gear: 0.83

It is the same transmission used in the E39 540i, but some changes were made to cope with the extra power the S62 engine produced. A reinforced clutch, rear differential utilising a shorter 3.15:1 ratio, and a limited slip differential with 25% maximum locking.

The E39 M5 suspension shared its basic aluminium-intensive MacPherson strut/multi-link design of the V8 engined E39 5 series. However, several changes were made by BMW M. Reduced spring height, 23 mm (0.9 in) lower. A specific shock valving, thicker front and rear anti-roll bars, polyurethane auxiliary springs, and steel balljoints.

Like all V8-powered E39 models, the E39 M5 was equipped with a recirculating ball steering system. Overall steering ratio was reduced to 14.7 from 17.9. It featured a Servotronic vehicle-speed-sensitive power assist which provides two levels of resistance controlled via console mounted Sport button. The Sport button also adjusted the electronic throttle butterflies for faster throttle response. The E39 M5 is equipped with four-wheel vented disc brakes measuring 345 mm (13.58 in) in diameter in front and 328 mm (12.91 in) in diameter in the rear. On European-specification models, the rotors are of a "floating" two-piece design for reduced risk of cone distortion. Their lower unsprung weight improves ride quality and traction on bumpy surfaces as well. Anti-lock brakes, EML (fly-by-wire) throttle control and Dynamic Stability Control (DSC) were standard.

During its five years in production, there were some cosmetic changes in 2001 to include:

• Revised headlights incorporating illuminated "Corona Ring" design (incandescent plastic rings surrounding the headlights, often incorrectly and nonsensically referred to as "Angel Eyes" despite BMW themselves clearly making reference to them as "Corona Rings," named for the outer plasma "atmosphere" of the sun visible during a solar eclipse.)
• Jewel tone Celis tail light design
• Park Distance Control sensors in the front bumper (previously in rear only)
• Thicker three-spoke M steering wheel identical to the one fitted to the E46 M3
• Grey instrument panel
• Improved solar sensor for standard automatic climate control
• Revised navigation/audio unit with larger (6.5-inch) monitor (Standard on US Spec 2001-2003)
• Rear head protection airbags added
• Second-generation M Mobility tyre repair system in place of earlier version
• Available M Audio System with special tweeters, Kevlar/carbon coaxial speakers and two subwoofers behind the rear console
• Alcantara headliner included with Extended Leather interior (previously only included with Complete Leather)

For the subsequent two model years, changes were limited to the addition of new exterior colors (from 9/01 production) and the upgrade to a DVD-based navigation system (from 9/02 production).

Performance The official BMW of North America statement (mentioned in the 2003 brochure) for the acceleration time from 0-60 mph is 4.8s. Official statements from BMW are typically conservative and many reviewers claim to have achieved this under 4.5 seconds and the less restricted European version is routinely clocked at 4.2. It is electronically limited to a top speed of 250 km/h (155 mph), making it the fastest 4-door saloon in the world at the time it was manufactured and just .1 (1/10) of a second off the 0-60 time of the latest M5 model.

E39 M5 Touring

Although an E39 M5 Touring was considered, and at least one prototype was constructed (in Titanium Silver with a Black Exclusive leather interior), BMW M decided not to produce an E39 M5 Touring due to financial considerations. In February 2010, as part of BMW's 25th Anniversary of the M5, they revealed this prototype M5 touring along with an E34 M5 Cabriolet, which also was never produced.

Flexible electronics design

Since the start of production the entire in-car entertainment system (Radio Function, Navigation System, Television and Telecommunications systems) is based on a very flexible automotive computer system. As a result the E39 models can all be easily upgraded with the newest BMW technologies including BMW's Bluetooth System, the DVD based Navigation system, as well as BMW's CD changers that play MP3s

The E60 M5 was introduced in 2005. It has a 4,999 cc (305.1 cu in) BMW V10 S85 engine redlining at 8250 rpm, and developing a peak output of 507 PS (373 kW; 500 bhp) and 520 N⋅m (380 lb⋅ft) of torque. Unlike some other BMW engines which utilise Valvetronic to infinitely vary valve lift to eliminate the throttle plate, this engine has individual throttle bodies per cylinder. The E60 M5 was the world's first production sedan to feature a V10 petrol engine.

Other key features include a stiffened aluminum chassis and a 7-speed SMG III sequential manual gearbox, also known as a single-clutch automated manual transmission. Front fog lights are unavailable for the M5, as the amount of air required to cool the brakes under spirited driving applications requires the spaces under the bumper, normally occupied by fog lights in other E60 cars, to be reallocated for air cooling ducts.

Despite the criticism of the Chris Bangle-designed chassis, the difficult iDrive interface, and the lack of smoothness of the SMG III transmission, the E60 M5 was the most successful M5, despite being on the market for one year shorter than the E39 M5. During its five year run, 20,548 units were built composing of 19,523 saloons and 1025 wagons. 8800 were sold in the U.S., all of the sedan variety. Great Britain and Ireland claimed 1776 examples, followed by BMW's home market of Germany with 1647 units, and 1357 were sold in Japan. Italian enthusiasts claimed 512 units, and 339 examples were sold in Australia.

Powertrain

The BMW M5, along with the E63/64 BMW M6, were designed to use the new Getrag SMG III single-clutch seven speed semi-automatic transmission. Gerd Richter, the head of BMW M, defended the decision to use a single-clutch sequential manual gearbox rather than a twin-clutch unit, saying "True, the dual-clutch system has a smoother automatic mode, and it performs seamless upshifts. For a 7-series, this may be the way to go. But an M car should always combine efficiency with emotion. That's why there are six shift speeds to choose from, from velvet glove to iron fist. That's why we cut the torque into seven slices. That's why we added special features like a hill holder, a designated drive program for steep climbs and descents, and a downshift assistant, which briefly dips the clutch to avoid destabilizing wheel spin." The SMG III transmission, while responsive at the track, has been criticized for its general lack of smoothness in everyday driving, and by 2010 it was considered outdated as most manufacturers were using dual clutch transmissions instead. Based on suggestions from the motoring press, BMW announced in October 2006 that a 6-speed conventional manual transmission would be available in North America, this became the base transmission in these markets while SMG III is an option. The 6-speed manual M5 was marginally slower, since the dynamic stability control could not be disengaged unlike the SMG version. This however, was changed with the release of a Service Bulletin in November of 2007 for a retrofit allowing DSC to be disabled as well as the function being implemented into the introduction of the 2008 model year M5 as well as the M6. The SMG III includes the "Launch Control" feature. However, the US spec vehicles have a reduced RPM to prevent vehicle damage and abuse.

The M5 features several Formula One inspired engine and transmission controls. There is launch control which allows maximum performance standing starts automatically. The Getrag SMG III single-clutch semi-automatic transmission has the option of changing to either automated or manual, as well as the speed at which shifts are completed (there are 11 shift programmes in total forming what BMW calls Drivelogic). Manual shifting can be done with either a console shifter, or the steering wheel mounted shift paddles, both of which are fitted to all SMG M5s. The console shifter is the type used on manumatic transmissions; tipping it backward (toward the "+") shifts up, while a forward tip (toward the "-") shifts down. The shifter can be moved to the left to access neutral and reverse. The car also features a "power" button on the navigation panel (labeled "M") which offers access to three modes: P400 (limiting the engine to 400 PS (294 kW; 395 bhp) for daily driving use), P500 (unleashes the full 507 PS (373 kW; 500 bhp)), and P500 S (for full power and sharper throttle response, selectable only from the "M Drive Settings" in the iDrive menu). P400 is the default start-up mode, the P500 modes are preselected using iDrive and then activated from P500 S using the "M" button.

Performance

The E60 M5 took the title of the most powerful midsize sport sedan when released, Along with direct competitors the Audi RS6 (C5) and the Mercedes-Benz E55 AMG, all three vehicles are quoted by their manufacturers to reach 0-to-62-mph in a time of 4.7 seconds.

The M5 was temporarily overtaken by several more powerful rivals, specifically the Mercedes-Benz E63 AMG (507 bhp (378 kW; 514 PS)), Audi RS6 (C6) (426 kW (579 PS; 571 bhp)), and the second generation Cadillac CTS-V (556 bhp (415 kW; 564 PS)) which bested the M5's Nürburgring lap time.

E61 M5 Touring (2007–2010)

E61 M5 Touring

The E61 M5 Touring was introduced in 2007, only the second M version of the 5-Series Touring after the E34. It shares the same drivetrain with its saloon sibling, and serves as a rival to the Audi RS6 Avant and Mercedes-Benz E63 AMG Estate. The Touring was never offered for sale in North America.

The E61 M5 Touring weights slightly less than 2,000 kg (4,409 lb) and from the factory can reach 175 mph (282 km/h), even though the car is electronically limited to 155 mph (249 km/h) . Jeremy Clarkson, of Top Gear, said of the "M5 is one of the most exciting cars made today. Only now, because this is an estate, your dog can come too.”

Prerelease information

The new M5 uses the S63 biturbo 4.4 Litre V8 with twin scroll turbocharging technology that is found in the BMW X5 M and X6 M, and the version in the M5 is expected to have an output of 560 hp (418 kW) and 502 ft⋅lb (681 J) of torque. Turbocharging the M5 has not gone unnoticed, with long time fans of the M series being disappointed that BMW seems to be moving away from traditionally high displacement naturally aspirated high-revving engines. Increasingly stringent international CO2 emissions and fuel consumption regulations are cited as the cause of death of the outgoing model's V10 engine, and the F10 M5 will cut CO2 emissions by 25%. The other advantage of turbocharging is that it generates considerably more low-end torque.

While the X5 M and X6 M currently have a 6-speed automatic transmission with Steptronic transmission, a dual clutch transmission will be used on the F10 M5, dropping the Getrag SMG III single-clutch 7-speed semi-automatic transmission used in the previous E60 M5. A manual gearbox option has been confirmed for the US market only.

The F10 M5 will be further influenced by BMW's EfficientDynamics program to lower the weight of the car. This will improve fuel consumption and enhance performance. BMW has partnered with carbon fiber manufacturers SGL group and Biermann has further speculated that carbon fiber will be employed substantially in the structure and shell to vastly reduce weight from the previous E60 model. Hybrid systems have been ruled out of the F10 M5's line up of gadgets because of the extra weight they will add to the car.

Official information

On June 15. 2011. BMW released official press informations about new M5.official info Most of internet unofficial informations are correct, car is powered by upgraded S63 engine which produces 560 hp and 680 Nm of torque. The high-revving V8 produces its 560 hp from 6000 to 7000 rpm, and redlines at 7200 rpm. Maximum torque is available from 1500 to 5750 rpm. Acceleration to 100 km/h (62 mph) is 4.4 seconds and top speed is limited to 250 km/h (155 mph), however it can be 305 km/h (190 mph) with M-Drivers-Package. Car weight is 1945 kg which is 90 kilograms more than previous model. Average fuel consumption is claimed to be 9.9 litres which is 31% less compared to 5.0 litres from V10 powered M5. Car is built on a modified F10 platform, wheelbase is shorter while body is 11 millimeters longer than standard 5 series. Other details mentioned in the report include an Active M-Differential with torque vectoring between the rear wheels and optional 20-inch light alloy wheels fitted with 265/35/20 front and 295/30/20 rear Michelin Pilot Super Sport tires. While the car’s official world debut isn’t set to occur until September at the Frankfurt Auto Show and later in North America at the LA Autoshow on November 18, the new 2012 BMW M5 has already made an appearance at the M Festival at the Nurburgring 24 Hours endurance race in Germany on June 23, the Goodwood Festival of Speed, and has been shown to select members of the M Driving Experience at the Salzburg Ring in Austria. The new M5 was reported a lap time of 7:55 around the Nurburgring race track which matches the ’Ring time of the Ferrari F430.

Engine is officially dubbed the S63tu. It has revised compression, higher lift camshafts, valvetronic intake technology for added response and higher boost at 22PSI compared to the S63 unit found in the X5/X6M. The compression has also been raised and the pistons have been strengthened to cope with the added boost and compression. Redline has been raised to 7200 and continues to build power up to redline, compared to other turbo cars that tend to die on the top end. The brake calipers will be colored blue and standard for all M5s at release. 19 inch multi spoke wheels are standard and 20 inch spilt 5 spoke wheels will also be available at launch.

First reviews

The F10 M5 is praised by journalists, admiring the car's performace and handling. Day-to-day driving is also supposedly much better than the E60 M5, with the gearbox and fuel economy cited specifically for their improvements over the old model. Concerns have been raised regarding the steering feel and weight, however the car has, once again, received overall praise for being the best performing super saloon currently on the market; an accolade retained throughout the five model generations.
