The M5 built as a touring car.
The M5 entered its second generation in 1988, the straight-six power unit originally displacing 3.6 and subsequently 3.8 litres, with output increasing first to 315 and then to 340 hp. Another change was that the engines no longer bore the “M” in their internal production code, but rather an “S” designating the origin of BMW Motorsport GmbH power units from now on. The customer is able to determine the difference at a glance, the letters “BMW” now being replaced by “M Power” on the valve cover, just as on the M3 four-cylinder. The M5 was initially introduced as a saloon and then at the beginning of 1992 as a touring to create a unique synthesis of a thoroughbred sports car and a sophisticated transport vehicle.
When the next 3 Series was set to make its appearance in 1990, Motorsport GmbH was already working on the new BMW M3 which was launched on the market in 1992. But the new car was no longer adorned by striking spoilers and widely flared wheel arches, like its predecessor. Instead, the new M3 – reflecting the signs of the times – came in a more discreet look and was recognisable to the connoisseur only through specific details – one of which, of course, being the unmistakable sound generated by the three-litre six-cylinder four-valve power unit developing maximum output of 286 hp. This M3 six-cylinder was also BMW’s first engine with VANOS variable valve timing, an infinitely adjustable system varying the intake camshaft as required. This system patented by BMW M boosts torque above all at low and medium engine speeds.
Another unique feature on this car seen for the first time was the introduction of engine management developed by BMW and with a capacity of 20 million instructions per second.
BMW M5 (1984-1988)
During the first half of 1981, BMW presented the second generation of the BMW 5 Series to the public. The new styling contours of the predecessor so typical of BMW were retained but the aerodynamic properties of the vehicle were enhanced by raising the rear end. The BMW M5 was developed as a new, independent car by BMW Motorsport GmbH based on the BMW 5 Series. The visual appearance only differs from standard 5 Series models in inconspicuous details. The high-power engine from the BMW M635CSi was used to power the car.
