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 do not cause any im‐
pairment of the operation or the service life of
the components.
