Vauxhall has announced the arrival of a new Aussie musclecar - the VXR8 - and it is more powerful and exciting than even the legendary Monaro.

The £34,995 saloon, based on Australia's Holden HSV Clubsport R8, goes on sale in July, powered by the same 6.0-litre V8 as the outgoing Monaro.

The engine now develops 420 horsepower, giving it enough grunt to sprint from 0-60mph in just 4.9 seconds.

It will also be the first VXR model to be offered with an automatic gearbox.
