IMPECCABLE ROAD MANNERS
   The C4 boasts impeccable road manners, with its McPherson type suspension at the front and flexible transverse beam at the rear, associated with ABS, emergency braking assistance and ESP. Braking performance is among the best in the segment, with excellent ABS and ESP control comfort.

MODERN, INNOVATIVE EQUIPMENT FOR RELAXED DRIVING
   The C4 features a range of modern, efficient driving aids designed for easy, relaxed driving.

• The lane departure warning system is a major step forward in driving safety. At speeds of over 80 kph, this system warns the driver if the car crosses a continuous or broken lane marking, if the indicator has not been activated. A vibrating mechanism mounted in the car seat is triggered on the side corresponding to the direction of vehicle drift, enabling the driver – who may have suffered a moment’s distraction – to take corrective action in time.

• Xenon dual-function, directional headlamps (dipped and full beam), generally reserved for vehicles further up the market, provide improved lighting for cornering.
• The C4 also features equipment more rarely found in this segment, such as a cruise control, a speed limiter, front and rear parking assistance with manoeuvres displayed on the multifunction screen, and a low tyre-pressure warning system.

NEW FEATURES FOR PROTECTING PASSENGERS AND PEDESTRIANS

With its array of equipment and features, the C4 sets high standards in active and passive safety.
• In particular, the C4 boasts the world’s first shape-optimised driver airbag. This feature, which relies on the fixed central section of the steering wheel, improves driver protection.
• Also, its design reflects efforts to protect pedestrians in the event of frontal impact The C4 is designed to limit the consequences of possible pedestrian impact (impact absorbers on the upper and lower part of the front end, aluminium bonnet with an inner panel perforated in the centre to absorb energy more effectively, etc.).

 A NEW EXPRESSION OF ONBOARD COMFORT
The interior design of the C4 places the emphasis on relaxation, with: • discreet, high-tech interior styling, reflected in the understated dashboard design,
• innovations for simplicity and ergonomics.
   For example, the multifunctional fixed-centred controls  steering wheel brings the main comfort functions (audio system, telephone, etc.) and driving aids (speed limiter, cruise control, etc.) within easy reach. This ergonomic feature, which places the emphasis on easy-to-use controls, promotes driving pleasure.
   The steering wheel is associated with a new driving information display unit. Vehicle speed, speed limiter and cruise control settings, etc. are displayed on a translucent strip in the centre of the dashboard. The display contrast adjusts instantly to ambient light conditions to ensure a clear read-out at all times.
   All these advanced functions create a relaxed atmosphere in the passenger compartment, further enhanced by the scented air freshener styled to match the interior, and the laminated side windows for acoustic comfort. In terms of practical features, the C4 features a host of stowage compartments including a boot foldaway partition to hold objects firmly in place.

 A COUPÉ AND A SALOON: DIFFERENT STYLES, SAME INTERIOR SPACE

   The C4 Saloon and the C4 Coupé each have their own distinctive style. However, they share the same generous interior space, contributing to the comfort of the passenger compartment.
  The saloon has rounded forms, while the coupé favours a sharper line. Both vehicles share smooth, fluid lines for outstanding aerodynamics, one of Citroën’s traditional strengths (Cd of 0.28 for the coupé and 0.29 for the saloon). The two vehicles also share the same interior space. Knee room for passengers at the rear is among the best in the segment (17 cm when the seat is pushed back to the maximum).
   By offering a saloon and coupé, Citroën is pursuing the strategy initiated in the supermini segment, where it has three complementary offers (C2, C3, and C3 Pluriel), each with distinctive styling to address wide-ranging customer tastes.
