The S62 engine (also known as S62B50) is a high-performance variant of the M62 which is fitted to the E39 M5 and E52 Z8. It is enlarged with a bore of 94 mm (3.7 in), a stroke of 89 mm (3.5 in) and a displacement of 4,941 cc (302 cu in).[9] It shares its basic architecture, including aluminium block, with the M62 engines.[9]
Previous M5 engines were assembled at M division headquarters in Garching, Germany but the S62 M5 engines were assembled at the Dingolfing assembly plant.[10]
Eight individual throttle bodies (one per cylinder) control the airflow into the engine,[10] these throttle bodies are electronically actuated (often referred to as "drive-by-wire"),[11] with a setting for the driver to select "normal" or "sport" mode throttle response. Bosch Motronic version MSS 52 is used to control fuel injection, ignition timing and other functions.[9]
Variable valve timing is used for both the intake and exhaust camshafts; the S62 was the first BMW V8 engine to incorporate this feature.[9] The compression ratio is 11.0:1 and hollow camshafts are used.[9] While the M62 engine uses a single-row timing chain, the S62 uses a double-row timing chain.
The S62 engine produces 294 kW (394 hp) at 6600 rpm and 500 N·m (369 lb·ft) at 3800 rpm.[12] The redline is 7000 rpm[WIKI]
