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.

A BMW M high performance version of the M62, called the S62 engine, was fitted to BMW's E39 M5 and BMW Z8, and both the Ascari KZ1 and Ascari A10.

## Design

[edit]

Like the BMW M60 engine it replaced, the M62 is a DOHC engine with four valves per cylinder, an aluminum block and aluminum 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

[edit]

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]

### Alpina F3

[edit]

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.[30] It has a bore of 93 mm (3.7 in) and a stroke of 85 mm (3.3 in).

Applications:[18]

* 1996-1998 Alpina B10 V8

### Alpina F4

[edit]

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 its emissions output although power output remained the same.[30] It has a bore of 93 mm (3.7 in) and a stroke of 85 mm (3.3 in).

Applications:[18]

* 1998-2000 Alpina B10 V8

### Alpina F5

[edit]

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.[31][32][33] It has a bore of 93 mm (3.7 in) and a stroke of 89 mm (3.5 in).

Applications:[18]

* 2002-2004 Alpina B10 V8S
* 2002-2003 Alpina Roadster V8

[edit]

Based on the production M62B44 the Racing Dynamics 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 its 7,200 rpm redline.[34] It has a bore of 94 mm (3.7 in) and a stroke of 93.0 mm (3.7 in).

Applications:[18]

* 1999-2001 Racing Dynamics R52 Sport

Chronology
Successor| BMW S65

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).[35]

The S62 engine produces 294 kW (400 PS; 394 hp) at 6600 rpm and 500 N⋅m (369 lb⋅ft) at 3800 rpm.[36] The redline is 7000 rpm.[37][38] 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.[35]

Other differences compared to the M62 include:

* Individual throttle bodies for each of the eight cylinders,[39] which are electronically actuated[40] and have driver-selectable "normal" and "sport" mode throttle response.
* Compression ratio is 11.0:1, compared with 10.0:1 for the M62[41]
* A double-row timing chain, compared with the single-row chain used by the M62[42]
* Hollow camshafts.[35]
* Engine control unit is a Siemens MSS 52[35]
* Dual air intakes and mass flow sensors[43]
* A semi-dry sump oil system, consisting of two additional scavenging pumps which activates during hard cornering[44][45]

Like the M62, the S62 has an aluminium block and head. The S62 was assembled at BMW's Dingolfing plant.[39]

Applications:

* 1998–2003 BMW M5 (E39)
* 2000–2003 BMW Z8
* 2005–2010 Ascari KZ1
* 2006 Ascari A10

## Bentley Arnage

[edit]

The 1998-2000 Bentley Arnage (Green Label) is powered by a Cosworth-developed twin-turbo version of the M62B44.[46] This engine produces 260 kW (349 hp) and 569 N⋅m (420 lb⋅ft).[47]
