Audi RS6: Video review

Fancy blasting from 0-62mph in just 4.5 seconds? Then hop into Audi's RS6 and hold onto your hat. The enormous power delivered by the twin-turbocharged V10 engine is matched by the car's fantastic grip, and the four-wheel drive gives fabulous traction in wet weather.

Quality, safety and luxury equipment are all top notch, too.

The downside? All that power means an insatiable thirst for fuel, and huge bills for insurance and company car tax will really sting.
