BMW M3 Technology
Vehicle features and options
This chapter describes model-specific equipment, systems, and functions that are currently available, or may become available in the future, even if they are not present in the vehicle.

High-performance engine
General information
With a displacement of 3 liters, the high-performance engine generates a maximum output of 473 hp, or 503 hp with Competition Model, and a maximum torque of .406 lb ft/550 Nm, or 479 lb ft/650 Nm with Competition Model.
With its spontaneous response characteristics, a very wide usable speed range results. The maximum RPM is 7,200 rpm and is electronically controlled. Because of the high engine dynamics, the maximum RPM with the vehicle stationary is reduced.
Warm-up
During the engine warm-up phase, the high-performance engine has a somewhat rougher running behavior because of the emission controls.
During the engine warm-up phase, the cold start occurs at an increased idle speed, which leads to increased acoustics of the exhaust system.

Compound brake
General information
The high-performance brake system has perforated compound brake disks.
Due to the specific design, temporary function-related noise may occur after an extended minor load.
The function-related noises have no effect on the performance, operational reliability, and durability of the brake.
Correct braking
To prevent function-related noises, depress the brakes hard a few times in regular intervals. Ensure that the traffic situation permits the braking.
With moisture on the brake disks, the brake system may be operated dry to prevent noise.
M carbon ceramic brake
General information
The high-performance brake system has perforated carbon ceramic brake disks.
Due to properties of the materials used, braking may be associated with louder function-related noises, e.g., in the event of an extended minor brake load or in wet conditions, just before the vehicle comes to a standstill.
The function-related noises have no effect on the performance, operational reliability, and durability of the brake.
The effects of moisture and road salt from using a car wash, dew formation overnight, driving in rain, etc., may render the braking effect comparable to that of a conventional brake system. If necessary, this reduced braking effect can be compensated for by depressing the brake with greater pedal force.
Correct braking and washing
To prevent function-related noises, depress the brakes hard a few times in regular intervals. Ensure that the traffic situation permits the braking.
With moisture on the brake disks, the brake system may be operated dry to prevent noise.
First clean brake disks and calipers with a steam cleaner or high pressure cleaner before washing the vehicle in an automatic car wash. This prevents salt crystals, for instance, from causing crusty deposits or buildup to form if the vehicle then remains stationary for a period of time. The cleaning effect of automatic car washes is usually not adequate for this in the area around the wheels.
Drivetrain
With this vehicle, particular value was placed on the direct connection from engine to the drivetrain. Due to the torsionally rigid design of the drivetrain, 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 clicking noises. The clicking noises do not impair the operation or the service life of the components.
