Fifth Gear

Tiff's on the limit in a very special Porsche 911 the 500bhp RS 4.0 of which a limited production run of only 600 will be made. Vicki test drives the maddest hybrid we have ever seen in the one of a kind Honda CRV tweaked by tuning company Mugen which cost 150K. Johnny's in Portugal to test the new Renault hybrid car the Fluence.
