Официальный мануал по двигателю M70 V12
These objectives meant a special challenge for the engineers developing such a large, high performance car. BMW developed a concept for realization of these objectives. An engine developing approx. 200 kW requiring a displacement of approx. 5 litres. Both V-8 and V-12 engines could be applied in this range. RMW deeded in favour of a 60 V 12 eng.ne for the following reasons.
— Limited forces of gravity due to small cylinder units.
— Short flame travel due to small cylinder units and therefore
realization of high compression ratios.
— Small ignition spacing, so that uniform engine torque is
reached.
