RenaultSport Clio 200: Paris 2012

Renault has unveiled the Clio RenaultSport 200 at the Paris Motor Show with a 1.6 litre turbo engine delivering 200bhp. The latest version of the Clio RS forgoes its naturally aspirated 2.0 litre engine for a turbo 1.6 litre delivering the same 200bhp but more torque – up more than 10 per cent. What dropping the 1.6 turbo has done to the Clio is make it more economical – Renault say it is 25 per cent more fuel efficient and, obviously, emissions drop comparably.

New Audi RS6 to get 572bhp V8

The 2013 Audi RS6 looks set to swap its V10 for the new Audi V8 with the wick turned up to 572bhp – the same as the old V10. Most of the new A6 range has now arrived in showrooms – including the S6 and Avant – but what’s still missing is a new RS6, the Audi that used to have the heart of a Lamborghini. But as we reported in April, the 2013 RS6 is well on the way but it will be losing its Lamborghini V10 with its 5.2 litres and 572bhp and will instead get the Audi/Bentley twin-turbo 4.0 litre V8.
