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.

Mazda Miata roadster passes 900,000-built milestone

Design Review: Audi Nuvolari quattro concept

Hot on the heels of the Pikes Peak study at Detroit in January, Audi today unveiled the Nuvolari quattro four-wheel drive concept vehicle at the Geneva Motor Show. In contrast to the Pikes Peak crossover SUV concept, with the Nuvolari, Audi's designers have created a classic, high-powered 2+2 GT coupe.   It's certainly powerful: a 5.0-litre V10 biturbo with FSI direct fuel injection with 600ps and a 0-100km/h time of 4.1 seconds means it's the most powerful roadgoing Audi engine ever developed.
