Maybach Zeppelin comes over the horizon

The Maybach Zeppelin - an even bigger waste of money than the standard Maybach Maybach has not exactly been an unmitigated success for Mercedes.

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.
