Chevrolet Corvette Stingray Convertible (2013) first official pictures

You wait ages for a new Corvette, and then six weeks after the new Stingray bows in at the 2013 Detroit atuo show, its soft-top sister is revealed at the Geneva motor show. The latest C7-generation Corvette drop-top uses the same mechanical package (big V8 up front, power sent to the rear wheels) as its fixed-head sister but adds an electrically-folding soft-top roof that you can lower remotely via pushing a button on the key fob. You can also drop the roof while on the move, at speed of up to 31mph.

Ferrari video of the next Enzo's HY-KERS hybrid

Ferrari has issued video of its new HY-KERS hybrid system bound for the new Enzo successor due later in 2012. It mates a V12 petrol engine with a brace of electric motors - one to drive the car's ancillary systems like cooling and power assistance, and the larger one to drive the rear wheels. This teaser video doesn't give away any incredible performance figures, but it does afford a glimpse into Maranello's thinking for its new hypercar.

Mercedes GLA goes subterranean

FOR SUV owners looking to test their cars’ off-road credentials, the obvious place to put them to the test probably isn’t nearly 200 metres underground. But that’s exactly where the new Mercedes GLA found itself as it descended into Winsford Rock Salt Mine, 620 feet beneath the Cheshire countryside. The working mine, which supplies much of the UK’s gritting salt for wintry roads, played host to four standard (apart from extra driving lights) GLA models, which were lowered down into the mine nose first before being let loose in the 130-mile network of tunnels.
