Predecessor BMW M60
Successor BMW N62

The BMW M62 is a naturally aspirated V8 DOHC engine produced from 1995 to 2005.[1] A successor to the M60, the M62 features Alusil cylinder liners[2] and a single row timing chain.[3] In 1998, the "Technical Update" (M62TU) added variable valve timing (VANOS) to the intake camshaft.

The S62 engine is M's high performance version of the M62.

Design[edit]

Like the M60 it replaced, the M62 has double overhead camshafts, 4 valves per cylinder, fracture-split forged connecting rods,[4] and aluminium block and cylinder head. Most of the M62 engines have an Alusil coating for the cylinders,[5] however some early M62 engines used Nikasil instead.[6][7]

The M62 uses a Bosch Motronic M5.2 engine control unit (DME)[8] and a hot wire MAF.[9]

1998 Technical Update[edit]

In 1998, a "Technical Update" was applied to the M62, resulting in the M62TU variants. New features include variable valve timing (single-VANOS, intake camshaft only) and electronic throttle control (called EML by BMW). The engine management (DME) was updated to Motronic ME7.2.[10][11]

The S62 engine (also known as S62B50) is the high-performance variant of the M62, which is fitted to the E39 M5 and the E52 Z8. The S62 was BMW's first V8 engine to have variable valve timing on both the intake and exhaust camshafts (double-VANOS).[22]

The S62 engine produces 294 kW (394 hp) at 6600 rpm and 500 N⋅m (369 lb⋅ft) at 3800 rpm.[23] The redline is 7000 rpm.[24][25] The bore x stroke is 94 mm × 89 mm (3.7 in × 3.5 in) for a total displacement of 4,941 cc (4.9 L; 301.5 cu in), compared with the 4,398 cc (4.4 L; 268.4 cu in) of the largest M62 engine at the time.[22]

Other differences compared to the M62 include:

As per the M62, the S62 has an aluminium block and head. The S62 was assembled at BMW's Dingolfing plant.[26]

Applications:

Bentley Arnage[edit]

The 1998-2000 Bentley Arnage (Green Label) is powered by a Cosworth-developed twin-turbo version of the M62B44.[33] This engine produces 349 bhp (260 kW) and 420 lb⋅ft (569 N⋅m).[34]
