Speed. Power. Control. Three things on the
mind of every BMW M engineer. In designing
the M3’s engine, no corners were cut, and no
boundaries were set. Their efforts resulted in a
powerful 4.0-liter V-8 engine, with a dynamic
414-hp output and 295 lb-ft of available
torque, as well as a maximum engine speed
of 8400 rpm. It’s the kind of muscle that will
catapult the M3 Convertible from 0-60 in just
5.1 exhilarating seconds.

To accommo date
the naturally aspirated engine, the M3 hood
features a contoured powerdome and dual
air intakes.
Thanks to the M3 engine block’s special
aluminum/silicon-alloy construction, the
cylinder surface is created by the exposed
hard silicon crystals in the alloy. This
eliminates the need for conventional coated
cylinder bores. For increased structural
stability, the M3 V-8’s crankcase is milled
as a complete forging.
To achieve smooth power distribution
through out the rpm range, the M3’s engine
is tuned to truly track-worthy specifi cations.
BMW’s Double-VANOS technology ensures
pinpoint-accurate valve timing, which allows
for optimal combustion at every rev range,
while lowering emissions.
In keeping with the M3’s racing-inspired
engineering, eight separate throttle but ter-
fl ies operate precisely and independently,
delivering amazingly quick throttle response.
In addition, the engine’s oil supply is carefully
regulated by an advanced wet sump system
to ensure adequate lubrication under any
conditions. The result: breathtaking accel-
eration out of the turns and onto the
straightaways.
An equally innovative engine management
system enhances performance. Ion fl ow
technology monitors the V-8’s combustion
process via the spark plugs, helping to
prevent knocking. How far can revolutionary
