The S62 engine is a high performance version of the M62 engine, with which it shares its basic architecture, including aluminium block. Manufactured by the M-Division at the Dingolfing assembly plant from 1998 to 2003, it was fitted to the E39 M5 and E52 Z8 along with a couple of Ascari's, one of which is still in production.

These engines are also known as S62B50 due to the 4941cc displacement. This was actually the first BMW V8 engine to feature VANOS on both the inlet and outlet camshaft, which are also hollow. As with all previous M-Division engines the S62 was fitted with Individual Throttle Bodies, but these were now electronically controlled which allowed differing throttle responses to be selected; both "normal" and "sport" settings were available for the driver. Bosch Motronic version MSS 52 is used to control fuel injection, ignition timing and other functions. The S62 also uses a double row timing chain as per the M60.
