“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The “Electronic Q2” system uses the braking system to create an
effect similar to a limited slip differential.
The front braking circuit, when accelerating around a corner, acts
on the inside wheel to increase the drive to the outside wheel (in-
creased load), dynamically and continuously distributing the torque
between the front drive wheels according to driving and road con-
ditions.
The system, combined with Mc Pherson front suspension, allows
particularly effective, sporty driving.
DST SYSTEM (Dynamic Steering Torque)
This function integrates Dual Pinion active steering into the opera-
tion of VDC. For particular manoeuvres, VDC controls the steering
to actuate a steering torque and assist the driver in the best pos-
sible way. The system operates the brakes and steering in a coor-
dinated manner to increase the suspension and safety level of the
car as a whole. The steering provides addition torque on the steer-
ing wheel.
RAB SYSTEM (Ready Alert Brake)
(“Dynamic” mode only)
By pre-approaching the brake pads (front and rear) after rapid ac-
celerator release, this function provides prompter braking and re-
duces stopping distance.
BRAKE ASSIST
(emergency braking assistance)
The system, which cannot be turned off, recognises emergency
braking (on the basis of the brake pedal operating speed) and
speeding up the response of the braking system. The Brake
Assist function is deactivated in the event of VDC system fault.
MSR SYSTEM
(Motor Schleppmoment Regelung)
This system is an integral part of the ABS, that intervenes, if there
is a sudden change to a lower gear, restoring torque to the engine,
thereby preventing excessive drive at the drive wheels which, es-
pecially in poor grip conditions, could lead to a loss in stability.
CBC SYSTEM (Cornering Braking Control)
This system improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking round bends when the ABS intervenes. This improves stop-
ping distances and above all vehicle stability when cornering.
