BMW M3

However, such rumors have yet to be substantiated, and the issue won't be definitively settled until BMW officially releases the new "3" convertible. The highest performance bike is the Firebolt XB12R and Lighting XB12S with an 1203cc engine that develops a claimed 103 horsepower (77 KW). Some believe the E90 convertible may be a retractable hardtop, similar to the Mercedes-Benz SLK. The Blast is the only model to use a 492 cc, 34 hp single-cylinder engine. It is rumored that the next-generation M3 will have a 425 hp (315 kW) 4.0 L V8, and there is much speculation as to whether or not it will be marketed in coupe or convertible form as the M4. Earlier models included the RR1000, RR1200, RS1200 West wind, RSS West wind, S2 & S2T Thunderbolt, S1 Lighting, M2 Cyclone, S3 & S3T Thunderbolt and the X1 Lighting. BMW was expected to announce an all-new M3 based on the E90 platform at the 2005 Frankfurt Motor Show (to be released in 2007), but this did not happen. Current production models, as of December 2005, are the Blast, Firebolt, Lightning, Lightning CityX and Ulysses XB12X.

The available SMG transmission, a Formula 1-style elctrohydraulic manual gearbox with no clutch pedal and steering wheel-mounted paddle shifters, is also a highlight. These features help create a leaner and more agile sport motorcyle compared to the previous generations. This was the highest specific output naturally aspirated engine ever made by BMW, producing 343 PS (333 SAE net hp (252 kW) in North America) and 365 N·m (262 ft·lbf) of torque. The ZTL front wheel is very innovative, but some see it as more marketing fluff than actual substance. The 2001 E46 M3 appeared worldwide with the new 3.2 L S54B32 engine. Two of the notable innovations are the use of the hollow frame as a fuel tank and the hollow rear swing-arm to hold the engine oil. The US-Spec E36 M3 was named Best-Handling Car by Car and Driver in 1997. Buell claims that what differentiates their motorcycles from their Harley-Davidson origins is the "Trilogy of Tech": mass centralization, low unsprung weight and frame rigidity.

Production of the sedan was halted in 1998, while the other models continued until 1999. It also incorporated, but did not invent, the inside-out front brake and "fuel in frame technology." (first for the industry). Starting in model year 1997, it was also available as a sedan with a convertible in 1998. In 2003, Buell introduced a whole new engine--so efficient it passed emission tests well into 2006. The 1996-1999 model years had displacement bumped up to 3.2 L, with 240 hp (176 kW) and 320 N·m (236 ft·lbf) which is the same engine used in the early M Roadster and M Coupe. In 1995 the engines were upgraded with Buell engineered parts and further upgraded in 1998. The reasons for the tamer car were largely due to excessive costs for the US market with the original engine and possible difficulty in getting the Euro engine to pass emission tests. These engines were originally built from Harley-Davidson XR1000 Sportster engines, after the 1000s were depleted Erik Buell used a basic 1200 Harley-Davidson Sportster engine.

The first E36 M3 to be imported to the United States was the 1995 model, which got a tamer 3.0 L engine with 240 hp (176 kW) and 305 N·m (225 ft·lbf) (S50B30US) and a different suspension. Most Buell motorcycles use four-stroke V-twin engines. The 3.2 Euro is also known as the M3 "Evolution" or "Evo". Buells typically employ radical frame designs and unconventional suspension systems that, along with the relatively high output Sportster engine, culminate in a nimble and atypical, however much less powerful and somewhat more expensive alternative to the Japanese sport bikes. These models are often described as the "Euro" models to differentiate them from the models sold in the US which were quite different. Buell started with a stock Harley-Davidson "Sportster" engine, then highly modified it and bolted it to a frame of his own design. The new SMG gearbox was also offered as an option. Mr.

For the 1996 model year the M3 was upgraded to a new 3.2 L, 321 hp (236 kW) engine (S52B30),a six speed gearbox and the M5's larger brakes. Buell motorcycles were first built in 1983 by a partnership between Harley-Davidson and Buell. This E36 coupe model got the 3.0 L S50B30 straight-6 engine, which produced 286 hp (210 kW). The company is the only significant manufacturer of "Sporting Motorcycles" in the United States. The replacement for the original M3 appeared at the 1992 Paris Auto Show. Since 1998 it has been a wholly-owned subsidiary of Harley-Davidson.
In 2004, Sports Car International named this car number six on the list of Top Sports Cars of the 1980s. The Buell Motorcycle Company is an American motorcycle manufacturer based in East Troy, Wisconsin and founded by ex Harley-Davidson engineer Erik Buell.

The E30 M3 is also a multiple winner of Macau Grand Prix, 24 Hours Nürburgring and Spa 24 Hours. The M3 was (and is) a successful racer, winning the Deutsche Tourenwagen Meisterschaft, European Touring Car Championship and even the one-off world title in 1987. Production of the original M3 (E30 coupe) ended in 1991. Evo III) some of which featured less weight, improved aerodynamics, and more power to keep the car competitive in racing folowing homologation rules.

Special editions and later homologation specials included the Evo I, Evo II and Sport Evo (AKA. The M3 had larger brakes and shared wheel bearings with the E28 5-Series. It also had three times the caster angle of any other E30. The M3 was equipped with flared fenders to accommodate a wider track with wider and taller wheels and tires.

The E30 M3 differed from the rest of the E30 lineup in many ways. 786 cabriolets were also produced. The first version produced 195 hp (143 kW), and later versions upped displacement to 2.5 L and 238 hp (175 kW). One of the main reasons for production of the road car was to homologate the M3 for Group A Touring Car racing, as an answer to the "2.3-16V"-model of the Mercedes-Benz W201 which was introduced in 1983.

Based on the 1986 E30 3-Series body, the first M3 was first introduced with a 2.3 L S14 engine, derived from the M10 straight-4. . The first M3 was based on the 1986's E30 range, and there has been an M version of every 3-Series since. The BMW M3 is a sports version of the popular compact BMW 3-Series automobile, made by BMW Motorsport.
