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.

Honda recalls CR-V to fix control-arm problem

Official: Mercedes SLS AMG Black Series

The new Mercedes-Benz SLS AMG Black Series has been revealed ahead of going on sale in the Summer of 2013. The SLS Black Series gets the usual mix for a Mercedes Black Series model – more power and less weight – and uses the same 6.2 litre V8 as the regular SLS but with the wick turned up to 622 horses from the regular, but hardly wanting, 583 thanks to a new air intake, cams, boost tweaks and better cooling. The oily tweaks for more power – and some weight shedding (70kg) – means the SLS Black can get to 62mph in 3.6 seconds – 0.2 seconds quicker than the regular SLS – and top out at 196mph (due to the extra downforce).
