BMW 5-Series automobile made by BMW Motorsport. First introduced at the Amsterdam Motor Show in 1984, the M5 has been made from various 5-Series versions throughout the years, including the E28, E34, E39 and most recently the E60. Originally, the M5 was hand-built utilizing the 535i chassis and a modified BMW M1 engine. When introduced, it was the fastest production sedan in the world.E28 M5 (1985-1988)

It was the product of demand for an automobile with the carrying capacity of a saloon (sedan), but the overall performance of asports car . It utilized the 535i chassis and an evolution of the engine from theBMW M1 . The M5 was handbuilt by Motorsport technicians and was the fastest production saloon (sedan) in the world.The M5 was offered in four different versions. The first version was the Left Hand Drive (LHD) Euro Spec M5. The second version was the Right Hand Drive (RHD) Spec M5. The third version was the North American Spec (NA or so-called 1988) M5. The fourth version was the South African (ZA) Spec M5. It's worth noting that production of the M5 continued well into Calendar Year 1988, ending in November 1988 which was well after production of the E28 chassis ended in Germany in December 1987.
The LHD, RHD Euro Spec M5s and the ZA spec M5s had the M88/3 powerplant which delivered convert|286|hp|abbr=on
DIN (210kW ) whereas the North American 1988 M5 was equipped with the S38 6-Cylinder engine that had acatalytic converter , which reduced the power output to convert|256|hp|abbr=on DIN (191 kW). The S38 differed from the M88/3 in that it had 9.8:1 compression versus the M88/3's 10.5:1. The S38 also used a dual-row timing chain where the M88/1 used a single-row chain. 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 NA 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 handful of US Models were also equipped with Black interiors
US 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 handful of 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 US M5 kept in BMW North America's Mobile Tradition collection is a 287 series car, a later 1987 build date car.
While every NA-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 atBMW Motorsport inGarching .With a total production of 2,191 the E28 M5 remains the rarest regular production BMW Motorsport car - after the BMW 850CSi (1510 units).

North America started in 1991 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'sDingolfing 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 a tolerance of within 5% of advertised output.The early E34 M5 used an evolution of the 24-valve
I6 found in the E28 M5 and E24 M635CSi/M6. The engine was designated S38B36, with a bore of convert|93.4|mm|in|1|abbr=on and stroke of convert|86|mm|in|1|abbr=on for a total capacity of 3535 ccm. The added stroke is due to a new forged steel crankshaft, though the camshafts were also changed. Compression 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 Motronicfuel injection , equal length stainless steel headers and three way ceramic catalysts. Originally it had a displacement of 3.5 L and produced 315 hp (235 kW), and convert|266|ft.lbf|N.m|abbr=on @ 4750 rpm. Cars sold in North America andSwitzerland , due to a differentcatalytic converter , produced 310 hp (229 kW).In second half of 1991, the engine displacement was increased to 3.8 L with the S38B38, except in North America and South Africa, which continued with the 3.5 L engine. Power was now increased to 340 hp (250 kW) SAE . Also in 1992, a Touring version was introduced in LHD form only 891 cars were made.
The M5 came with an unusual wheel design. From 1989-1992 the M5 featured the M-System wheels. These wheels were 17x8J, but came with a bolted-on wheel cover. 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.

In fact the E39 M5 was almost not built at all; BMW believed that the 286 bhp 540i was powerful enough, but when Jaguar released the XJR (320 hp) and Mercedes-Benz introduced the W210 E55, which had over 350 bhp (354 hp), BMW responded to the competition with a convert|394|bhp|abbr=on 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 L and produced Auto PS|400. The engine featured a 7000 rpm redline, Double-VANOS , which varies the intake and exhaust valves 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:*First gear: 4.23
*Second gear: 2.54
*Third gear: 1.62
*Fourth gear: 1.23
*Fifth gear: 1.00
*Sixth gear: 0.83It 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 utilizing a shorter 3.15:1 ratio and a limited slip differential with 25% maximum locking.
The E39 M5 suspension shared its basic
aluminium -intensiveMacPherson strut /multi-link design of theV8 E39 5 series. However, several changes were made by BMW M. Reduced spring height, 0.9 inch (23 mm) 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 that 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 13.6" in diameter in front and 12.9" 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 were standard.During its 5 years in production, there were some cosmetic changes, these include:
*Revised headlight design incorporating illuminated "Angel Eye" rings
*"Jeweled" "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
*Rear head protection airbags added
*Second-generation M Mobility tire 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).
The E39 M5 is capable of accelerating from 0-62 mph in 5.3 seconds, although many reviewers claim to have achieved this under 5 seconds. It is electronically limited to a top speed of convert|155|mi/h|km/h|0|abbr=on [cite book |title=Deutsche Autos seit 1990, vol.5 |last=Kittler |first=Eberhard |year=2001 |publisher=Motorbuch |location=Stuttgart |isbn=3-613-02128-5 |pages=187] , making it the fastest 4-door sedan in the world at the time it was manufactured. Once delimited, top speeds of an indicated 187mph (180mph actual) are possible.
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.

weight = convert|1830|kg|lb|0|abbr=onThe E60 M5 was introduced in 2005. It has a naturally aspirated 5.0 L BMW V10 S85 engine redlining at 8250 rpm and developing a peak output of 500 SAE hp (507 PS, 373 kW) with convert|383|ft.lbf|N.m|abbr=on of torque. Unlike some other BMW engines which utilize Valvetronic to infinitely vary valve lift to eliminate the throttle plate, this engine has 1 individual throttle body per cylinder. This gives it quicker response. Other key features include a stiffened aluminum chassis and a 7-speed SMG III
manual transmission .The BMW M5, along with the new M6, were designed to use the new SMG III
electrohydraulic manual transmission . The transmission, while responsive at the track, has been criticized for its general lack of smoothness in everyday driving. In October 2006 BMW announced that a 6-speed manual transmission would be available in North America based on suggestions from the motoring press. Unfortunately, this gearbox reduces acceleration performance slightly. The 6-speed manual M5 was marginally slower, since the stability control cannot be disengaged as per theSMG version. The SMG III includes the "Launch Control" feature, which allows maximum performancestanding start s automatically. However, the US spec vehicles have a reduced rpm to prevent vehicle damage and abuse.The M5 features several F1 inspired engine and transmission controls including launch control,
dynamic stability control , and the option of changing to either automated or manual as well as the speed at which shifts are completed (there are 11 shift programs in total forming what BMW calls Drivelogic). Manual shifting can be done with either a floor shifter or the steering column-mounted shift paddles (another F1-inspired feature), both of which are fitted to all SMG M5s. The floor 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 steering wheel (labeled "M") which offers access to three modes: P400 (limiting the engine to convert|400|hp|abbr=on for daily driving use), P500 (unleashes the full 507 hp) 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 i-Drive and then activated from P400 using the "M" button.Other than a firm ride, the E60's criticisms are excessive fuel consumption, and the general design criticisms of the
Chris Bangle E60 body. Recent developments by Audi, specifically the production of the more powerful RS6(572 bhp), rivalling the M5, have inspired BMW to go back to the drawing board. The 2009 M5's power output is expected to hit the 600+ bhp mark,up from its current 507 bhp.Frontal fog lights are unavailable for the E60 M5: The amount of air required by the engine forces the space normally occupied by the front fog lights under the bumper to be reallocated for air intakes.

Furthermore, the new M5 also features theVANOS variable valve timing system, and EMC (engine management system ) which sports the most powerful computer processor currently approved for automobiles, the MS S65 processor. This processor also controls and measures many other now 'standard' safety and performance systems such as the DSC (dynamic stability control)), which incorporatestraction control as well as various other mechanical and electronic systems.The M5 also includes more then 18 different transmission settings.Tuners
*BMW Motorsport has not yet produced any special variants of the E60. However, German tuner
Hartge has created a modified version without the electronic speed limiter; it also features upgraded wheels and tires to cope with high speed.
*Hamann "Edition Race" — Tuner Hamann produces several E60 variants, but the most exotic is "Edition Race," with a wide body-kit, larger wheels and tires, a tuned engine (including removal of the speed limiter), and customized interior details. It has a top speed of about convert|192|mi/h|km/h|abbr=on (down from the stock +convert|206|mi/h|km/h|abbr=on due to the drag from the wider tires).
