Audi's Cross Cabriolet design study, an impressive-looking open-top car with all-terrain ability, is wowing the crowds at the Los Angeles Auto Show.

With dimensions close to those of the A5, the four-seater Cross Cabriolet features a 3.0-litre V6 turbo-diesel engine with a 0 to 62mph time of 7.2 seconds, top speed 149mph, and a combined fuel cycle return of 38.6mpg.

When the going gets tough, the four-wheel drive Audi concept can raise its body height at the touch of a button - electric motors are fitted under each wheel's spring plate.
