Vehicle features and options Compound brake
This chapter describes model-specific equip-
ment, systems, and functions that are currently
available, or may become available in the fu-
ture, even if they are not present in the vehicle.
General information
The high-performance brake system has per-
forated compound brake disks.
Due to the specific design, temporary function-
related noise may occur after an extended mi-
nor load.
Additional information:
Vehicle equipment, refer to page 8.
The function-related noises have no effect on
the performance, operational reliability, and
durability of the brake.
High-performance engine
General information
Correct braking
With a displacement of 3 liters, the high-per-
formance engine generates a maximum out-
put of 453 hp and a maximum torque of
406 lb ft/550 Nm.
To prevent function-related noises, depress
the brakes hard a few times in regular inter-
vals. Ensure that the traffic situation permits
the braking.
With its spontaneous response characteristics,
a very wide usable rotational speed range re-
sults. 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.
With moisture on the brake disks, the brake
system may be operated dry to prevent noise.
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.
Warm-up
During the engine warm-up phase, the high-
performance engine has a somewhat rougher
running behavior because of the emission con-
trols.
During the engine warm-up phase, the cold
start occurs at an increased idle speed, which
leads to increased acoustics of the exhaust
system.
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.
