The RS6 is due to return to Audi's product line-up next year, with prices starting at around £77,000 for the practical 189mph super-estate.

Powered by a 4.0-litre twin turbo V8 TFSI engine, the new RS6 not only has a smaller engine than the previous, 5.0-litre twin-turbo V10 engined RS6, but it also has 28bhp less power.
But despite the smaller engine, the RS6 has more torque, up to 700Nm, and performance figures are much improved over the old old-V10 powered model, which tipped the scales at over two tonnes.

Audi claim that the new RS6 will be able to get from 0-62 in just 3.9-seconds, and go on to a top speed limited to 189mph – but only if you opt for the optional dynamic packages, otherwise the car is limited to either 174mph or 155mph.

Cylinder deactivation, which can shut down half of the cylinders under normal loads, and start-stop technology have also improved the car's economy by a claimed 40 per cent. Audi say the new RS6, which is 100kg lighter than the previous model, can achieve a combined figure of 28.8mpg, emitting 229g/km of CO2.



The new RS6 will also be the first RS model to feature air-suspension, but for die-hard fans, standard, steel suspension can be specified. A sports exhaust system is also available, and the RS6 features small valves in the exhaust system, allowing the driver to make the engine more vocal at the touch of a button.

The new RS6 will be available to order from Spring 2013 with the first deliveries due in the summer.
