RCA Citroen/Exa Double Challenge project

Second year students at the Royal College of Art in London revealed a series of projects at their interim degree show last week. Developed in collaboration with French automaker Citroen and the Exa Corporation, a leading supplier of aerodynamic software, the Double Challenge project asked students to design an ultra-compact model that could establish a unique Citroën e-vehicle aesthetic for the future, all while adhering to certain aerodynamic criteria that would not only reduce energy consumption and ensure stability at speed, but also visually communicate efficiency through its design. The project, which kicked off in October last year, was closely followed by representatives from Citroen and Exa, who examined each of the projects and chose a winner, Heikki Juvonen, at the event last week.

Mercedes SLS GT3 race car leaks early

Just before Christmas we reported on a new Corsa-based SUV on the way from Vauxhall and Opel which looks like it’s going to be the Opel Mocha (and, we assume, the Vauxhall Mocha too). But in this new ‘One World’ for cars, where North America actually gets the sort of cars they would once have derided as too small to consider, the Mocha is also going on sale in the US.
