BMW M60

The BMW M60 was a naturally aspirated V8 petrol engine produced from 1992 to 1996, and it was the first V8 BMW had built in more than 25 years. A V8 prototype for the E23 7 Series never reached production, and development of the M60 began in 1984. It has double overhead camshafts and four valves per cylinder driven by a dual-row timing chain, with Bosch Motronic 3.3 control and coil-on-plug ignition. To save weight it used aluminium for both block and head, magnesium valve covers and a plastic intake manifold, and it was the first BMW car engine with split connecting rods, made as one sintered piece and then fractured for an exact fit. The 3.0 litre M60B30 and 4.0 litre M60B40 powered the E34 5 Series, E32 and E38 7 Series and E31 8 Series, and the M62 replaced it.
