Audi RS7 to lap Hockenheim – DRIVERLESS

Audi are taking an RS7 round Hockenheim completely autonomously Every car maker – from Mercedes to Volvo and Ford – is working hard to make autonomous driving a reality, and it looks like we’re just a few years away from seeing cars being driven by computers, with the driver relegated to passenger in many daily driving tasks. Now it’s Audi’s turn to demonstrate the progress they’re making with autonomous technology by taking an RS7 round the Grand Prix track at Hockenheim without a driver having control. It’s arguable that taking a driverless car round a track – even at race speed – is far less of a technological task than having a car running driverless through a cityscape with all its variables, but it’s an impressive demonstration nonetheless.

Super-rare Rolls-Royce Silver Shadow II Shooting Break up for auction

And this example could be yours for a snip – it’s going up for auction with Bonhams at the Beaulieu Sale on 7 September 2013 with an estimated price of £12,000 to £16,000.

Volkswagen XL1

This, remarkably, is the production version of the Volkswagen XL1, the most fuel-efficient production car in the world, a car we'll see in Geneva in a little over a week. Barely changed from the concept version shown at the Qatar motor show two years ago, the production XL1 is the first production result of VW's 1-liter project – to design a car that uses less than 1l/100km (282.5mpg imperial) – that started with the lozenge-shaped, tandem-seat 2003 1L and the later L1 of 2009. The XL1 actually beats that by sipping just 0.9 liters with CO2 emissions of 21g/km.
