High performance V8 engine
The high-revving V8 engine draws a maximum 
power of 420 hp/309 kW and a peak torque of 
295 lb ft/400 Nm from a displacement of 
244 cu in/4 liters. Its spontaneous response 
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.
Warming up the engine
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.
For further information on warming up the 
engine, refer to Tachometer on page

Compound brake
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-
ble during braking. However, this does not 
affect the brake's performance, safe operation 
or stability under load.
Braking correctly
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.

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.
