Audi's 305km/h Sport Quattro concept

Just days before the Frankfurt Motor Show Audi has revealed its headline act – the new 305km/h Sport Quattro concept.

Built to celebrate the 30th anniversary of the original Sport Quattro, this recreation boasts a stonking 522kW/800Nm petrol-electric drivetrain comprising a twin-turbo 4.0-litre V8 and small plug-in electric motor.

Channelled through an eight-speed automatic gearbox to all four wheels, Audi claims the Sport Quattro shoots from 0-100km/h in just 3.7 seconds – making it quicker than the brand’s current halo sportscar, the Audi R8 V10.

Styled by a team of in-house designers, the Quattro weighs in at a fairly hefty 1850kg and is expected to fetch more than $250,000 when it goes on sale in limited numbers at the end of 2015.
