BMW M62


BMW M62 is a naturally aspirated V8 petrol engine which was produced from 1995 to 2005. A successor to the BMW M60, the M62 features an aluminium engine block and a single row timing chain.
In 1998, a technical update included VANOS 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, hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used Alusil for the block material, however some early M62 engines used Nikasil cylinder coating instead.
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 and a hot wire MAF.

Technical Update

In 1998, a "Technical Update" was applied to the M62, resulting in the M62TU variants. New features include single-VANOS and electronic throttle control. The engine management was updated to Motronic ME7.2.

M62B35

The M62B35 has a bore of and a stroke of.
Applications:
In 1998, the Technical Update was applied, resulting in the M62TUB35. Versions used in the E39 5 Series application have slightly more power than versions used in the E38 7 Series.
Applications:
  • 1998–2001 BMW 7 Series 735i/735iL -
  • 1998–2003 BMW 5 Series 535i -

    M62B44

The M62B44 has a bore of and a stroke of.
Applications:
  • 1996–1998 BMW 5 Series 540i
  • 1996–1998 BMW 7 Series 740i/740iL
  • 1997–1999 BMW 8 Series 840Ci

    M62TUB44

In 1998, the Technical Update was applied, resulting in the M62TUB44. In the United States, power for TU models was increased to.
Applications:
  • 1998–2003 BMW 5 Series 540i
  • 1999–2001 BMW 7 Series 740i/740iL
  • 1999–2003 BMW X5 X5 4.4i

    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 and stroke of. 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:
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.
It has a bore of and a stroke of.
Applications:
  • 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.
It has a bore of and a stroke of.
Applications:
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. It has a bore of and a stroke of.
Applications:
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. It has a bore of and a stroke of.
Applications:
  • 1999-2001 Racing Dynamics R52 Sport

    S62

The BMW S62 engine 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.
The S62 engine produces at 6600 rpm and at 3800 rpm. The redline is 7000 rpm. The bore and stroke are and respectively. This results in a displacement of, compared with the of the largest M62 engine at the time.
Other differences compared to the M62 include:
  • Individual throttle bodies for each of the eight cylinders, which are electronically actuated and have driver-selectable "normal" and "sport" mode throttle response.
  • Compression ratio is 11.0:1, compared with 10.0:1 for the M62
  • A double-row timing chain, compared with the single-row chain used by the M62
  • Hollow camshafts.
  • Engine control unit is a Siemens MSS 52
  • Dual air intakes and mass flow sensors
  • A semi-dry sump oil system, consisting of two additional scavenging pumps which activates during hard cornering
Like the M62, the S62 has an aluminium block and head. The S62 was assembled at BMW's Dingolfing plant.
Applications:
  • 1998–2003 BMW M5
  • 2000–2003 BMW Z8
  • 2005–2010 Ascari KZ1
  • 2006 Ascari A10
