MG Rover has surprised the industry with the launch of the much-anticipated V8-powered MG ZT 260 V8.

The 4.6-litre super saloon has been re-engineered to be rear-wheel drive and uses the muscular V8 engine that powers the Ford Mustang.

Exterior changes have been minimal, with four tail pipes and a V8 badge being the most obvious difference from lower power versions, but MG Rover claims the real distinction will be in the performance: the V8 version reaches 155mph and 0-60mph in barely six seconds.

Rob Oldaker, MG Rover Group's product development director, said: 'The MG ZT 260 V8 demonstrates our commitment to deliver cars of true pedigree and character. Our choice of a big, torquey engine has been vindicated as this is a deceptively quick and efficient cross-country car.'

The ZT 260 V8 will start with a price tag of £27,995 on-the road for the saloon and £28,995 for the ZT-T estate.
