Citroen C-Cactus concept's green secrets

By Tim Pollard Motor Shows 17 September 2007 12:52 Citroen C-Cactus: the lowdown Citroen’s C-Cactus concept car on show at Frankfurt signals the start of a programme to investigate simplifying the construction of its cars –stripping out unnecessary weight, complexity and emissions from its everyday hatchbacks and saloons.

Citroen DS Wild Rubis SUV Concept: Official (+ Video)

Revealed this morning, the DS Wild Rubis Concept is a proper full-size SUV from the French car maker which, we assume, is being targeted primarily at China. Citroen’s history in recent years with full size cars has been poor, with no one but the French themselves buying them in any sort of reasonable numbers.

Renault Alpine A110-50

As we reported earlier this week, the Renault Alpine A110-50 prototype will be shown at the 2012 Monaco Grand Prix this weekend. Designed by Yann Jarsalle and Concept and Show Car Director Axel Breun the A110-50 effectively relaunches the historic Alpine brand despite being essentially a reworked version of the Renault-branded DeZir concept unveiled at the 2010 Paris Motor Show. As well as the addition of various Alpine design cues – the stylized yellow spot lamp pods, central hood flute and blue and orange colorway – the car is built on the platform of the RenaultSport Megane Trophy racecar and so therefore requires cooling provisions for its mid-mounted engine.
