Brake-steer
Brake steer offers the benefits of a torque
vectoring differential, but is integrated into the
braking system reducing weight and providing
excellent speed of response.
If the system detects that the car is starting to
understeer through a corner, the inside rear
brake is gently applied. This helps to increase
the yaw rate of the car, making the car feel
more resistant to understeer. The lateral āgā
force is also increased giving better handling
characteristics.
If the driver uses too much throttle exiting a
corner, the inside rear wheel increases speed,
which without brake steer could cause the car
to become unstable. In this situation, brake
steer will again gently apply the brake on the
inside rear wheel, thereby restoring traction
and stability.
Electronic brake pre-fill
If the accelerator pedal is suddenly released,
the electronic brake pre-fill function
immediately brings the brake pads into contact
with the discs, ensuring rapid braking.
Electronic Stability Control
Electronic Stability Control monitors driving
stability and traction between the tyres and the
road surface.
Electronic Stability Control detects when a
wheel starts to spin or the vehicle starts to skid
and stabilises the vehicle by braking individual
wheels, and/or limiting the engine power
output. This also assists when pulling away on
wet or slippery road surfaces and stabilises the
vehicle when braking.
Electronic Stability Control operation is
indicated by the warning light flashing.
NOTE: The Electronic Stability Control
warning light is permanently illuminated
when Track mode is selected on the Handling
Control.
WARNING: If the Electronic Stability
Control warning light flashes, do not
deactivate Electronic Stability Control.
Adapt your driving style to suit road and
traffic conditions.
Electronic Stability Control cannot reduce
the risk of an accident if you drive too fast.
Electronic Stability Control is unable to
override the laws of physics.
NOTE: Electronic Stability Control only
functions properly if wheels with the
recommended specification tyres are used.
Electronic Stability Control is activated
automatically as soon as the engine is running.
