High performance V8 engine
Compound brake
The high-revving V8 engine draws a maximum
power of 420 hp/309 kW and a peak torque of
Your BMW M3 is equipped with a high-perfor-
mance brake system with perforated com-
pound brake discs.

Due to special design features of the perforated
compound brake discs, operating noise is audi-

affect the brake's performance, safe operation
or stability under load.
results in a very wide effective rpm range. The
maximum engine speed lies at 8,400 rpm and is
electronically controlled. Due to the high engine
dynamics, the maximum engine speed is lim-
ited to 7,000 rpm when the vehicle is standing.
Braking correctly
Warming up the engine
To keep the brake system in optimal condition,
it is advisable to apply the brakes at regular
intervals as appropriate for the character of the
vehicle.
During the warm-up phase, the high-perfor-
mance V8 engine runs a little more roughly due
to its emissions control system.
For technical reasons, the exhaust system
sounds slightly metallic when the engine is
cold.
Refer also to Corrosion on brake rotors on
page 117.
For further information on warming up the
engine, refer to Tachometer on page 68 and
Engine oil temperature on page 69.
Drive train
In your BMW M3, special emphasis was placed
on the direct connection between the engine
and drive. The torsionally rigid execution of the
drive train results in acoustic feedback of the
torque, as is typical in sports cars. Clacking
sounds can arise during load changes. They do
not impair functionality or shorten the lifespan
of any component.
