2011 Audi R8 GT, an AW first look

Three years after it burst onto the supercar scene, Audi has unveiled a hard-core version of its R8 called the GT. Based on the existing mid-engine R8 V10 and incorporating aerodynamic, weight-saving and mechanical developments used by the company's R8 LMS GT3 race car, Ingolstadt will build just 333 copies of the new 560-hp four-wheel-drive performance flagship. Pricing has not yet been revealed, but given the extent of the changes to the new two-seater, buyers should expect a hefty premium over the R8 V10's $147,000 price tag when the GT goes on sale in North America.

New Range Rover Sport takes on Pikes Peak – and wins

The new Range Rover Sport takes on the Pikes Peak Hillclimb Pikes Peak is an unforgiving Hill Climb, spanning 12.42 miles and 156 corners, rising to 4,300 meters above sea level with oxygen levels at the top down to just 58 per cent of those at sea level, making it incredibly hard for both man and machinery to function. But despite the challenge, Land Rover has taken the new Range Rover Sport up Pikes Peak in a new record time for a production SUV, covering the 12.42 mile course of twists and turns in just 12m 35.61s at an average speed of 59.17mph. You won’t be surprised to learn that Land Rover choose to use the new RRS with the 5.0 litre Supercharged engine for the record run, but apart from fitting a roll cage and harness seatbelts, the Sport had no modifications at all.

Mercedes-Benz axes Maybach

High ranking Mercedes-Benz sources have confirmed to Autoweek that the underperforming Maybach brand will be officially killed off in 2013. The decision to disband Mercedes-Benz’s upper luxury marque comes after a decade of disappointing sales for the Maybach 57 and 62 and a recent decision from the German car maker’s chairman Dieter Zetsche not to push ahead with the development replacement models – the likes of which were tentatively due out in 2014 – owing to what one insider describes as a “positive move to focus greater attention on the Mercedes-Benz brand” . “We’ve come to the conclusion that it is better to cut our losses with Maybach than to continue into an uncertain future with a brand that has failed to live up to original sales expectations," the insider said.
