The fastest gear changes take place in an astonishing 80 milliseconds. A tap on the paddle, or a flick of the gear lever delivers instantaneous changes - it is 'shift by wire'. SMG II, the latest system on the new M3, offers a significant leap forward with this technology.ĭeclutching and gear shifting is carried out electro-hydraulically following computations made by the engine management system and a new transmission control unit. In 1996, BMW became the first manufacturer to offer a clutchless manual gearbox on a commercial road car and half of E36 M3 owners specified it. BMW anticipate at least 50 per cent of customers will request the SMG II option that is available on both the M3 Coupé and Convertible. With 11 separate programmes which can be operated by two paddles behind the steering wheel, by the traditional gear selector, or a mixture of both, it can also be driven in self-selecting mode where the gear changes take place automatically. Available only on the M3, SMG II is a clutchless manual gearbox drawing on BMW's William F1 transmission technology.

The ACO coincided with Porsche and changed the rules such that the BMW would need an additional 100 lbs of weight and 20% larger air restrictors or make 1000 road going examples. The motivation behind this would be to satisfy homologation regulations which stated at least one road going version needed to be sold.Īfter decimating the competition in the GT class, Porsche complained the BMW car was streching the rules too far. In accordance with the regulations of the Automobil Club de l’Ouest (A.C.O.), which also organizes the Le Mans 24 Hours, BMW Motorsport was planning on building a limited production run of road-ready M3 GTRs. This engine is very different from the V8 found in the M5 and has yet to been seen in any E46 road car. This short-stroke, high-speed unit epitomizes the tradition of M power and is compact enough to fit into the M3. Beneath the beefy silhouette of the M3 GTR beats a powerful heart: a four-litre V8 engine delivering more than 400 bhp.
