The Citroen C4 - Best in Class Drag Coefficient | Part TwoPublished 20 November 2004
Highly aerodynamic, with a best in class drag coefficient of 0.28 for the coupe the same as for the Porsche 911 Carrera - the C4 also has plenty of room inside, where there are numerous useful touches including a brilliantly practical foldout boot partition that divides the boot into four separate compartments.
On the inside, where the C4’s impressive design continues, customers will discover remarkably high levels of refinement and quality. The attention paid to detail includes impressive touches like the damped push-open drawers on the dashboard and an abundance of soft-touch trim that helps to create a refined environment.
One of the first things to notice is the neat and tidy dashboard look. The unique design of the steering wheel, which features a fixed central hub around which are located key controls, not only frees up the dashboard but ensures that most of the essential controls are placed close to the driver’s fingertips. Using such a wheel design has also enabled Citroen to introduce a world safety first, allowing the shape of the driver’s airbag to more closely match that of the driver’s body.
The dashboard also features an innovative, easy-to-read translucent digital display, which is perfectly readable in all light conditions, including bright sunshine, thanks to its sophisticated technology that adjusts to the prevalent lighting conditions. Citroen’s C4 really is full of useful new features. Helping to ensure that the cabin is always a pleasant place to be, models equipped with air conditioning also boast a built-in air freshener.
Customers can select from a choice of nine scents and, by simply slotting a cartridge into the diffuser next to the air vent, can ensure that their car matches their mood.
The new C4 is the first in the sector to offer a Lane Departure Warning System (LDWS). A major advance in active safety, this clever device uses sensors to detect if the car is drifting across lanes, maybe because of driver tiredness or a loss of concentration. If the indicators have not been activated and the car’s speed is above 50mph, the system alerts the driver via a vibrating mechanism in the seats.
Additional technologies normally reserved for far more expensive cars include cruise control and speed limiter - standard across the C4 range - as well the availability of Xenon Dual Function Directional headlamps. This advanced headlamp design, which operates on both dipped and main beam settings, significantly improves the field of vision during night time driving.
