Renault Alpine A110-50: Official & on video

Renault Alpine A110-50 - it's official The Renault Alpine A110-50 – based on the Mégane Trophy platform with a Renault DeZir body – is officially revealed. We had our doubts that the Renault Alpine A110-50 photo we published earlier this week was real, but it seems it was; which goes to show we should really lock up our scepticism more securely. And now, as promised, Renault has revealed their first Alpine in almost twenty years in the A110-50, a car that has the underpinnings of the Megane Trophy and a body that seems to owe most of its DNA to the electric Renault DeZir Concept.

Porsche celebrates 50 years of the 911 at Pebble Beach

As one of the most accomplished road-going supercars ever created, it's easy to see why the 911 is also a consummate champion in the motorsport arena – and to celebrate that fact, at Pebble Beach 2013 there was a huge array of road and race 911s, courtesy of Porsche itself along with a stack of private owners.Click through the gallery to see our pick of these great cars...

Ariel Atom 3.5 (2012) first official pictures

It's difficult for Ariel to come up with a mid-life refresh for its cars - there simply aren't that many bits to fiddle with in the first place. Still, the boys from Somerset must have succeeded, because what we have here is the freshly updated Ariel Atom 3.5. As the name suggests, it's a development of the Ariel Atom 3, with a crop of minor visual  tweaks and some mechanical changes too, keeping Caterham and BAC looking over their shoulders.
