BMW M62
Template:Infobox automobile engine
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
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
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
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 Script error: No such module "convert". and a stroke of Script error: No such module "convert"..
Applications:[18]
- 1996-1998 Alpina B10 V8
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 its emissions output although power output remained the same.[30] It has a bore of Script error: No such module "convert". and a stroke of Script error: No such module "convert"..

Racing Dynamics R52
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 Script error: No such module "convert". and a stroke of Script error: No such module "convert"..
Applications:[18]
- 1999-2001 Racing Dynamics R52 Sport
S62
Template:Infobox automobile engine
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 Template:Cvt at 6600 rpm and Script error: No such module "convert". at 3800 rpm.[36] The redline is 7000 rpm.[37][38] The bore and stroke are Script error: No such module "convert". and Script error: No such module "convert". respectively. This results in a displacement of Script error: No such module "convert"., compared with the Script error: No such module "convert". 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
The 1998-2000 Bentley Arnage (Green Label) is powered by a Cosworth-developed twin-turbo version of the M62B44.[46] This engine produces Script error: No such module "convert". and Script error: No such module "convert"..[47]
