BMW M62 is a naturally aspirated V8 petrol engine which was produced from 1995 to 2005.[1] A successor to the BMW M60, the M62 features an aluminium engine block[2] and a single row timing chain.[3]

In 1998, a Technical Update included VANOS (variable valve timing) for the intake camshafts.

The S62 engine is the BMW M high performance version of the M62, which was released in the E39 M5, BMW Z8, Ascari KZ1, and the Ascari A10.

Design

Like the BMW M60 engine it replaced, the M62 is a DOHC engine with four valves per cylinder, an aluminium block and aluminium heads. The M62 has fracture-split forged connecting rods,[4] hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used Alusil for the block material,[5] however some early M62 engines used Nikasil cylinder coating instead.[6][7]

Alusil technology integrates silicon throughout the aluminum cast so that liners or treated bores within this block family are not needed.

The M62 uses a Bosch Motronic 5.2 engine control unit (also called "DME")[8] and a hot wire MAF.[9]

Technical Update

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

M62B35

The M62B35 has a bore of 84 mm (3.3 in) and a stroke of 78.9 mm (3.1 in).[3]

Applications:[18]

M62TUB35

In 1998, the Technical Update was applied, resulting in the M62TUB35.[3] Versions used in the E39 5 Series application have slightly more power than versions used in the E38 7 Series.

Applications:[18]

M62B44

The M62B44 has a bore of 92 mm (3.6 in) and a stroke of 82.7 mm (3.26 in).

Applications:[18]

M62TUB44

Technical Update version (M62TUB44)

In 1998, the Technical Update was applied, resulting in the M62TUB44. In the United States, power for 2001-2003 540i models was increased to 216 kW (290 hp).[19][20]

Applications:[18]

M62TUB46

The M62TUB46 is based on the M62TUB44. Revisions include full metal vanos hubs. 10.5mm lift intake and exhaust camshafts. Stronger valve springs. Bore of 93 mm (3.7 in)Stroke of 85 mm (3.3 in). Underdriven crank shaft drive pulley. Two-piece oil scraper ring instead of three-pieces. 93 mm pistons with reduced height due to the increased stroke.

Applications:[18]

Alpina F3

The Alpina F3 was developed by Alpina and based on the M62B44 engine. Released late in 1996 it used a modified M62B44 block supplied to Alpina from BMW featuring a bore of 93mm. It also featured a modified cylinder head, different intake camshafts, a crankshaft with increased stroke along with different pistons, a different air intake manifold and exhaust manifolds as well as custom engine programming.[22] It has a bore of 93 mm (3.7 in) and a stroke of 85 mm (3.3 in).

Applications:[18]

Alpina F4

Following with updates to the regular production M62B44 the F4 was a revised version of the Alpina F3 engine and featured variable valve timing on the intake camshafts, an electronically controlled throttle body and a slight increase in power. The Alpina F4 received a revision into the F4/1 in late 2000 which slightly increased fuel efficiency while decreasing it's emissions output although power output remained the same.[22] It has a bore of 93 mm (3.7 in) and a stroke of 85 mm (3.3 in).

Applications:[18]

Alpina F5

The F5 was Alpina's final iteration of the M62B44 engine, it featured all the same technology as the F4/1 but with an increased displacement due to an increased stroke thanks to a modified crankshaft. The increased stroke necessitated an oil pan with additional clearance as well as revised intake camshafts and exhaust camshafts from the M62B46 production engine.[23][24][25] It has a bore of 93 mm (3.7 in) and a stroke of 89 mm (3.5 in).

Applications:[18]

Racing Dynamics R52

Based on the production M62B44 the Racing Dyamics R52 engine featured a billet crankshaft, special pistons with stock connecting rods and a modified cylinder head which work together to raise the compression ratio to 11.3:1. It also features custom tubular exhaust manifolds, different camshafts and a modified engine computer which lets the engine spin to it's 7,200 rpm redline.[26] It has a bore of 94 mm (3.7 in) and a stroke of 88.8 mm (3.5 in).

Applications:[18]

The BMW S62 engine (full model code 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 double-VANOS (variable valve timing on the intake and exhaust camshafts).[27]

The S62 engine produces 294 kW (400 PS; 394 hp) at 6600 rpm and 500 N⋅m (369 lb⋅ft) at 3800 rpm.[28] The redline is 7000 rpm.[29][30] The bore and stroke are 94 mm (3.7 in) and 89 mm (3.5 in) respectively. This results in a displacement of 4,941 cc (301.5 cu in), compared with the 4,398 cc (268.4 cu in) of the largest M62 engine at the time.[27]

Other differences compared to the M62 include:

Like the M62, the S62 has an aluminium block and head. The S62 was assembled at BMW's Dingolfing plant.[31]

Applications:

Bentley Arnage

The 1998-2000 Bentley Arnage (Green Label) is powered by a Cosworth-developed twin-turbo version of the M62B44.[38] This engine produces 260 kW (349 hp) and 569 N⋅m (420 lb⋅ft).[39]
