Audi RS7 Sportback (2013) first official pictures

This is the new Audi RS7 Sportback, just unveiled at the 2013 Detroit auto show. It's an A7 Sportback given the hardcore RS treatment, meaning a 552bhp and 516lb ft 4.0-litre bi-turbo V8 that will sprint the RS7 to 62mph in 3.9sec. That's faster than the latest Porsche 911 – it seems life just got a bit harder for the Mercedes CLS63 AMG and BMW M6 Gran Coupe.

Patrick Long and the Porsche GT3 RS 4.0: Caffeine Delivery System

If you were Porsche's only North American factory driver, and if you'd won at the 24 Hours of Le Mans, you might feel as if you had every right to be a less-than-swell character. After all, those bona fides unquestionably position you as one of the finer shoes on the planet. Patrick Long, however, is a nice dude.

Range Rover Sport RS caught on video at Nurburgring

Range Rover Sport RS caught on video at Nurburgring The new Range Rover Sport is only just starting to fin its way on toi the road after its debut at the Geneva Motor Show in March, but Land Rover are already planning a more potent version – the Range Rover Sport RS. The ‘RRSRS’ is Land Rover’s answer to cars like the Porsche Cayenne Turbo S and comes equipped with the same supercharged V8 as the new XJR, XFR-S and XKR-S, offering around 542bhp, which should give the already very able Range Rover Sport proper supercar performance – something in the region of 4.5 seconds 0-60mph seems likely. Despite the Range Rover Sport RS blatting round the Nurburgring with a fair degree of swirly camouflage, you can already see it’s getting a new front bumper with bigger intakes and a redesign to the back bumper too.
