The BMW M6x range of engines are a line of V8 DOHC piston engines which were produced from 1992 to 2005. The first version, the M60, was the first V8 engine BMW had produced for 25 years. This was replaced by the M62. Together, the engines were used in various BMW models (E31, E32, E34, E38 & E39) and were also sold to other manufacturers to use in their cars.

The M60 was in development from as early as 1984. One of the the main aims of the development process was to reduce the size and weight of the engine, and CAD was used extensively to aid this.

As a Motorsport engine, the M62 was designated S62, and saw action in the E39 M5 and the roadster Z8.

Versions

All M6x engines consisted of aluminium cylinder blocks and cylinder heads and then plastic inlet manifolds. They were also DOHC with four valves per cylinder.

M60

The M60 engine was driven by a dual-row timing chain. Valves had hydraulic lash adjustment to reduce maintenance, and the camshaft chain drive was self-adjusting. There was no distributor, each cylinder having its own ignition coil. Fuel injection and ignition are controlled by the Bosch Motronic 3.3 system. There was a 3.0l and a 4.0l version of this engine. It's worth noting that these engines used the famous Nikasil cylinder bore linings.

M62

Added to the BMW range in 1996, the M62 was largely the same as the M60 with just a few revisions. The timing chain was now a single-row timing chain, Alusil replaced the Nikasil cylinder liners, and in 1998 VANOS was added.

There was 4 different capacities of the M62 offered, two of which were later available with VANOS. The VANOS engines were given the designation of M62TU.
