Citroen C-Buggy

Citroen will show their latest concept in Spain at the Madrid Motor Show next week. Chopping the roof off last year's C-AirPlay brings the concept closer the Smart Crossblade seen in 2001, and proposes a potential direction for a more leisure-orientated supermini. Just as open-cars are philosophically opposed to closed ones, Citroen has carried this equation through to the trim as well: the gray exterior of the C-Buggy contrasts with the white of the C-AirPlay, while the green interior inverts its forbear?s rouge.

2013 Audi A3 sketches revealed

2013 Audi A3 Hatch - there's also a saloon in the gallery below We’ve already had something of a glimpse of part of the next generation Audi A3 with the reveal at Geneva last month of the Audi A3 Concept. That Audi A3 Concept – which came complete with 400bhp and a boot – was really a look at the next generation RS3 in saloon guise – an Audi A3 that will go down a storm in an America quickly realising the joys of something smaller and swift. But now, for whatever reason, Audi has decided to release sketches of the 2013 Audi A3 in both saloon and hatchback form, together with a single sketch of the interior.

Video: Fiat creates café racer 500 for SEMA

Fiat is preparing a café racer-style 500 for this week's SEMA show by stripping down an Abarth version to take it "down to the essence of what you need to drive a car." The café racer philosophy of ‘more speed, less comfort' was born around the 1960s British 'biker scene and while initially focussed on increasing performance, quickly developed into a culture as concered with 'the show' as 'the go'. "It takes something like this to really get noticed at SEMA," says Craig Buoncompago, Project Manager at Fiat Product Design. "The Café Racer is really going to be one special car that you guys should really come and see." The 500's roof has been chopped, while also shorn of its door handles and being fitted with hot rod billet rims.
