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.

Lexus GS 300h: Shanghai Motor Show

Offering much better economy than the GS 450h, it offers not only a viable alternative for private buyers looking for a bit of beautifully built Japanese luxury with lower running costs, but also makes the GS a much more appealing option for company car drivers – probably where most of the sales will be made. Lexus are aiming for Co2 emissions below 110g/km for the GS 300h (the IS 300h manages 99g/km) which will give headline economy around 60mpg – a third better than the GS 450h can manage. Power comes from the same hybrid drivetrain as the IS 300h, which means a 2.5 litre petrol mated to an electric motor and delivering 215bhp and o-62mph in around 8.5 seconds.
