Citroen's future-looking Cactus concept

Exterior
While the styling cues are obviously drawn from the existing Citroen range (those slim LED headlights are lifted from the new C4 Picasso, the rounded bumpers look very C3 Picasso and the 3D-effect 'light tunnel' taillights are almost straight from the DS3 Cabrio) the look is much cleaner and more pared-down than has been the Citroen norm of late. It's rather refreshingly simple, we'd say and bodes well for Citroen's future style.

Citroen calls the design "pure and functional" and an interesting innovation is the design of the bubble-wrap like bumps in contrast grey on the sides and corners of the car. Called Air Bumps, they actually really are like bubble wrap for your car and can deflect by as much as 2cm without marking or denting, saving your paint and panel work in tight car parks or when other careless drivers nudge up against you. The days of door dings may well be over. Citroen will put the Air Bumps into production on the showroom C4 Cactus, and has patented the technology. They'll be available in a contrast colour or in a more disguising shade to blend in with the body.

Interior
The cabin is, in style, as pared back as the exterior, with all the dials and most of the buttons replaced by two TFT screens, a seven-inch one in front of the driver for the instrument cluster and a larger eight-inch screen in the centre that controls the infotainment and many of the climate controls. So many functions are taken over by these screens that there are actually only five physical switches on the dashboard, a level of simplicity that Citroen wants to carry forward into the production model. While the idea has been to make the cabin simpler and user-friendly, it's not actually skimping on equipment, another indication that Citroen doesn't want to go down the Dacia route. Air conditioning and satnav will be standard or optional, depending on the model and the gearbox is a 'robotised manual' EGS unit, controlled by push-buttons on the dash and steering wheel paddles.

Another interesting feature that may well make it through to the production model is the bench front seat. Actually, it's not really a bench seat at all - it still only seats two people - but Citroen believes that such a design creates for a friendlier environment, where the passenger and driver feel equal in the cabin and not separated.

Those clamshell doors won't be on the showroom C4 Cactus though - expect to see conventional doors on the production version.

Mechanicals
The show car uses Citroen's HybridAir concept, which combines a HDi diesel engine with a powerful air pump. This compresses air under high pressure in a tank, which can then be released to add extra power when needed, such as overtaking. Citroen claims that the car can manage 94mpg with this innovative drivetrain, which will go on sale eventually, but the C4 Cactus will make its debut with conventional petrol and HDi diesel engines.

Anything else?
The Citroen C4 Cactus is surprisingly compact. It's actually between a Nissan Qashqai and Juke in length, and in spite of the rough-road-friendly 21cm ride height, the car is actually the same height overall as a Citroen DS3.
