BMW M3 engineering

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 62 and

Engine oil temperature on page 63.

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.

Refer also to Corrosion on brake rotors on

page 107.

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.
