Active dynamics control
A system that allows the driver to change
the handling and performance
characteristics of the vehicle.
Airbrake
The Airbrake is a moveable wing that
enhances the vehicle's driving stability and
braking performance by increasing rear
downforce.
Anti-lock braking system (ABS)
The ABS prevents the wheels from locking
when you brake. This allows the vehicle to
be steered during braking manoeuvres.
Automatic driver recognition cards
A card which must be on the person entering
the vehicle or the tracker system signals that
the vehicle is being moved without
authorisation.
Brake assist system
The brake assist system operates in
emergency braking situations. If you depress
the brake pedal quickly, the brake assist
system automatically increases the force
being applied to the brakes and thus
shortens the stopping distance.
Brake disc wiping
Brake disc wiping operates when the
windscreen wipers are switched on. It
prevents moisture build up on the brake
discs during periods of heavy rain, by
applying the brakes momentarily, so that the
pads touch the discs.
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 vehicle is
starting to understeer through a corner, the
inside rear brake is gently applied. This helps
to increase the yaw rate of the vehicle,
making the vehicle feel more resistant to
understeer. The lateral ‘g’ 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 vehicle to become unstable. In this
situation, brake steer will again gently apply
the brake on the inside rear wheel, thereby
restoring traction and stability.
Cylinder cut
Cylinder cut operates during automatic
upshifts in Sport and Track powertrain
modes and manual upshifts in Comfort
powertrain mode.
When calling for an upshift under hard
acceleration, fuel is interrupted (cut) in a
defined number of engine cylinders. This
rapidly decrease the engine torque and
engine speed, allowing faster upshifts to be
achieved. This will make the upshift more
audibly noticeable than a normal upshift.
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, enabling more rapid
braking.
Electronic stability control (ESC)
ESC monitors driving stability and traction
between the tyres and the road surface.
