BMW M62
Template:Infobox automobile engine
BMW M62 is a naturally aspirated V8 petrol engine which was produced from 1995 to 2005.<ref>Template:Cite web</ref> A successor to the BMW M60, the M62 features an aluminium engine block<ref>Template:Cite web</ref> and a single row timing chain.<ref name="usautoparts">Template:Cite web</ref>
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,<ref>Template:Cite web</ref> hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used Alusil for the block material,<ref>Template:Cite web</ref> however some early M62 engines used Nikasil cylinder coating instead.<ref name="bmw-planet">Template:Cite web</ref><ref name="bmw-planet2">Template:Cite web</ref>
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")<ref>Template:Cite web</ref> and a hot wire MAF.<ref>Template:Cite web</ref>
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.<ref>Template:Cite book</ref><ref>Template:Cite web</ref>

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.<ref name="Alpina">Template:Cite web</ref> It has a bore of Template:Convert and a stroke of Template:Convert.

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).<ref name=usautopartsS62 />
The S62 engine produces Template:Cvt at 6600 rpm and Template:Convert at 3800 rpm.<ref>Template:Cite web</ref> The redline is 7000 rpm.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> The bore and stroke are Template:Convert and Template:Convert respectively. This results in a displacement of Template:Convert, compared with the Template:Convert of the largest M62 engine at the time.<ref name=usautopartsS62>Template:Cite web</ref>
Other differences compared to the M62 include:
- Individual throttle bodies for each of the eight cylinders,<ref name="bmwmcars1"/> which are electronically actuated<ref>Template:Cite web</ref> and have driver-selectable "normal" and "sport" mode throttle response.
- Compression ratio is 11.0:1, compared with 10.0:1 for the M62<ref>Template:Cite web</ref>
- A double-row timing chain, compared with the single-row chain used by the M62<ref>Template:Cite web</ref>
- Hollow camshafts.<ref name=usautopartsS62 />
- Engine control unit is a Siemens MSS 52<ref name=usautopartsS62 />
- Dual air intakes and mass flow sensors<ref>Template:Cite web</ref>
- A semi-dry sump oil system, consisting of two additional scavenging pumps which activates during hard cornering<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
Like the M62, the S62 has an aluminium block and head. The S62 was assembled at BMW's Dingolfing plant.<ref name="bmwmcars1">Template:Cite web</ref>
