Audi Sport quattro Concept

Celebrating 30 years of the Sport Quattro, Audi has revealed its spiritual successor ahead of its debut at next week's Frankfurt motor show. The broad concept – which measures in at 4,602mm long, 1,964mm wide, 1,386mm high sitting on a wheelbase of 2,784mm – features a number of the same design cues we saw on the 2010 quattro concept, the 1983 Sport quattro and the original Ur-quattro. These include the angular, flat C-pillars and the rectangular headlamps and rear lamps.

BMW M3 coupe gets stripped down to go club racing

BMW's M division is back in the business of building specialty street-legal race cars with a new lightweight version of the M3 called the GTS. The lightweight coupe, set to go on sale in early 2010 at a yet-undisclosed price, was conceived as a limited-edition model primarily for club-based racing in much the same way that Porsche builds the 911 GT3 Clubsport. But in a clear effort to link its track-based activities with the production-car side of its business, BMW's M division is offering the new car with a homologation package that will allow customers to register the M3 GTS for street use.

Mercedes GLA 45 AMG on video ahead of Detroit debut

Mercedes GLA 45 AMG (pictured) on video ahead of Detroit deut What promises to be the best performing car in the compact SUV/Crossover segment – the Mercedes GLA 45 AMG – was officially revealed this week ahead of its debut at the Detroit Auto Show. With the same 355 bhp, 2.0 litre turbo engine as the A 45 and CLA 45 AMG – and with 4WD – the GLA 45 AMG offers stunning performance in a high-riding compact shape that promises to embarrass all but the most extreme performance SUVs on the market. Now, ahead of next week’s debut, Mercedes AMG has released new video of the GLA 45 AMG which does a decent job of highlighting the cosmetic tweaks and purposeful stance the GLA has.
