Bentley SUV EXP 9 F: The Genesis +video

The Bentley SUV EXP 9 F arrives at Geneva Bentley has sent us video explaining the EXP 9 F SUV Concept, and we’ve talked to UK owners and dealers about the new SUV. There’s no doubt Bentley are serious about producing the EXP 9 F – or a variation of it – as Bentley’s first SUV (but perhaps not their first ‘Truck’) simply because the market demands it. But the EXP 9 F that arrived at Geneva this week really wasn’t what anyone was expecting; it seems to have the nose of the Mulsanne bolted on to a very square body with a big hatch at the back and looks more like a truck than a sporty or luxury SUV.

Porsche Panamera Sport Turismo concept (2012)

This is the new Porsche Panamera Sport Turismo concept car, unveiled on the eve of the 2012 Paris motor show. We hear that we won’t see a Sport Turismo version of the current Panamera, but this concept instead previews the facelift treatment that will be applied to Porsche’s four-door saloon as part of a mid-life refresh in 2013. And beyond that the Sport Turismo showcases a second bodystyle than will join the range when the Mk2 Panamera appears in late 2015.
