for the S14 inline-4 engine and the S70/2 V12 engine. A version of this engine was later used in the South African version of the 745i, of which 209 examples were built between 1984 and 1986, as well as the E24 M6/M635CSi and E28 M5. The engine has six separate throttle bodies, twin-cams, 4 valves per cylinder, and generates a power output of at 6,500 rpm and of torque at 5,000 rpm in the road version, giving the car a top speed of . The engine was mated to a 5-speed manual transmission made by ZF Friedrichshafen equipped with a 40% locking limited slip differential. Steering, suspension and brakes The M1 has an unassisted rack and pinion steering, double-wishbone suspension system with adjustable coil springs and Bilstein gas filled dampers. The road car had softer suspension bushings to have better ride quality and tractability. The ventilated brakes of the car measured at the front and at the rear and were constructed from steel. The M1 used special Campagnolo alloy wheels measuring 7x16-inches at the front and 8x16-inches at the rear fitted with Pirelli P7 tyres (having sizes of 205/55 VR15 at the front and 225/50 VR15s at the rear). Interior The M1 has a half-leather and half-cloth interior. Its motorsport roots meant that the car had a basic interior layout with many parts sourced from other BMW models. The interior had amenities such as air conditioning, power windows and a stereo but had unadjustable seats and only had a left-hand-drive configuration. Production The fibre glass body of the M1 was manufactured by Italian firm Italina Resina which was located in Modena, Italy. The chassis was manufactured by another Modenese firm, Marchesi. The body of the car was completed by Italdesign at their manufacturing facility located in Turin along with the interior. The partly finished cars were then delivered to German specialist manufacturer Baur where final assembly took place by hand. The hand-built M88/1 engines were supplied by BMW from Munich to be installed in the cars. The completed cars were shipped to BMW Motorsport in Munich for final inspection and delivery. Only 453 production cars were built, making it one of BMW's rarest models. Out of the 453, 399 were road going units while 53 were made for motorsport. Accolades The M1 had various successes in motorsports. In 2004, Sports Car International placed the car at number ten on their
