Optimised running gear
The
characteristics of Citroën’s first SUV are thoroughly up to brand
standards following the considerable efforts made on the original
vehicle to provide the C-Crosser with the best possible trade-off
between ride comfort and roadholding.
The vehicle is
fitted with MacPherson-type suspension at the front and multi-link
axles combined with a large track and a 20 mm anti-roll bar at the
back, for enhanced vehicle stability and active safety. The multi-link
rear axle and its geometry provide excellent comfort by maintaining
load height. The C-Crosser thus combines a top-flight ride with
impeccable roadholding for segment-leading driving pleasure and
handling.
This achievement is boosted by 18-inch wheels fitted
with special 225/55 R18 Michelin tyres.
The
centering, linearity and elasticity of the steering system have also
been engineered to optimise comfort, whatever the road surface.
The
C-Crosser features hydraulic variable-assistance power steering with a
decreasing-flow pump, thus linking the system to engine speed.
To
round out its road prowess, the C-Crosser has an aluminium roof
weighing 5 kg less than a metal equivalent and lowering the centre of
gravity by 4 mm.

High-performance brakes
The
C-Crosser brakes were developed to respect Citroën standards on brake
pedal feel in terms of bite, pedal pressure and efficiency.
The
C-Crosser’s braking system features ventilated discs with twin-pot
callipers at the front and discs at the rear, combined with ABS and
electronic brakeforce distribution (EBD).
Standard
equipment also includes the Electronic Stability Program (ESP), which
can be deactivated using a button on the fascia band to the left of the
steering wheel. It is coupled with traction control to prevent skidding.
All-wheel drive for safe journeys
With
the C-Crosser’s all-wheel drive system, drivers get to choose from
three transmission settings, depending on road conditions and driving
style: two-wheel drive, four-wheel drive and lock mode, all of which
are selected using a single control behind the gear lever.
- Two-wheel drive:
used on tarmac-surfaced roads, guaranteeing high grip (dry road). The
vehicle has a front-wheel drive 2WD system, which cuts fuel consumption
by reducing the number of parts in movement.
- Four-wheel drive: this is the
recommended setting as the torque split between front and rear axles is
managed automatically. The front wheels turn more than the rear wheels.
Torque is electronically distributed to the rear wheels by an
electronic control unit (ECU) according to grip conditions, for optimal
roadholding in all circumstances.
- LOCK mode: recommended for reduced
grip conditions (snow, sand or mud). In this setting, the ECU sends 1.5
times more torque to the rear wheels than in 4WD mode, increasing
traction through a better front/rear balance.
This “on request” transmission system
is managed by an ECU that automatically varies the torque split between
the front and rear wheels for maximum traction. The ECU factors in
information including:
- vehicle speed,
- steering angle,
- the difference in rotation speed between front and
rear axle,
- the pressure on the accelerator pedal.
With
this new-generation all-wheel drive system, the C-Crosser can run
permanently in 4WD mode with optimal front/rear torque distribution,
providing optimised roadholding in all driving conditions and thus
maximum safety.
