BMW M4 technology
High-performance engine

The high-performance engine gets a maximum power of 317 kW and maximum torque of 550 Nm from a displacement of 3 liters. With its spontaneous response behavior, a speed range of wide utility results. The maximum engine speed is 7,600 rpm and is electronically controlled. Because of the high engine dynamics, the maximum engine speed with the vehicle stationary is progressively deactivated after a short time.
Warm-up
During the engine warm-up phase, the high-performance engine has a somewhat rougher running behavior because of the emission controls.
When the engine is cold, the exhaust system has a slightly metallic undertone due to the nature of the system.
For more information about the warm-up procedure: Engine speed and engine oil temperature.
M carbon ceramic brake

The high-performance braking system has perforated carbon-ceramic brake disks and is designed for use on racetracks.
Due to properties of the materials used, braking may be associated with louder function noises, particularly in wet conditions, just before the vehicle comes to a stop. However, this has no effect on the performance, operational reliability and durability of the brake.
The effects of moisture and road salt, from using a carwash or dew formation overnight for example, may render the braking effect comparable to that of a conventional braking system. This may be perceived as reduced braking effect and can be compensated for if necessary by pressing the brake pedal harder.
Before washing the vehicle in an automatic carwash or wash tunnel, clean the brake discs and brake calipers with a steam jet or high-pressure washer as well, to prevent encrustations and dirt buildups, caused by salt crystals, for example, if the car is immobile afterwards. The cleaning effect of automatic carwashes or wash tunnels is usually not adequate for this in the area around the wheels.
To do this, also follow the instructions in Washing the vehicle and Braking safely.
Drive train
With this vehicle, particular value was placed on the direct connection from engine to the drive train. Due to the torsionally rigid design of the drive train, as is typical in a sports car, the transmission of the torque also gives acoustic feedback.
When there are load changes, this may result in clacker noises. They do not cause any impairment of the operation or the service life of the components.
Driving on racetracks
Requirements
Before driving on a racetrack:
Participation in BMW Driver Experience Training.
Check engine oil fill level and replenish as necessary.
Have vehicle checked at a service center.
Hints
Racetrack operation leads to increased wear. The vehicle is not designed for motorsports competitive use. This wear is not covered by the warranty.
The standard brake linings and the wear indicators are not designed for racetrack operation. For more information and advice, contact your service center.
