Video: Watch a Mini Countryman do a backflip

We've seen a backflip on a snowmobile, we've seen the double backflip from Travis Pastrana on his dirtbike, and we saw Rhys Millen almost land a backflip in his off-road truck on New Year's Eve. Apparently, Mini thought it would cap the fad's run by flipping a car. Extreme sportsman, freestyle skier and rally driver Guerlain Chicherit made the attempt at the winter sports resort of Tignes in France.

Tech secrets of the Land Rover Discovery Vision Concept

Land Rover's Discovery is celebrating its 25th year in 2014, but the brand is already looking to the future. The Discovery Vision Concept, unveiled in New York earlier this week, gives a taste of the design language of the next Discovery (which is due next year), as well as an extended family of Discovery models. It also previews some eye-popping new technology that could be used on future Land Rovers and Range Rovers.

BMW X4 Leaks

We have the first official photos of the BMW X4 SUV – the ‘Lifestyle’ version of the X3 – which we expect to debut at the Shanghai Motor Show this month. We have the first leaked images of the X4 that show a BMW X3 with the same sort of treatment as the X5 got to turn it in to the X6, and create what BMW like to call an SAC – a Sports Activity Coupe. Apart from the changes to the body – and less room in the back – you can expect the X4 to offer much the same under the skin as the X3 – albeit at a premium price – which will mean – for the UK at least – will mean everything from an X4 xDrive 18d SE through to an X4 xDrive 35d M Sport.
