Mercedes E-class Cabriolet at Detroit motor show 2010

Here's our first look at the new Mercedes E-class Cabriolet, unveiled at the 2010 Detroit Auto show. It's the fourth addition to the E-class range, and as with the latest E-class Coupe, the new drop-top replaces the old CLK. The new E-class Cabriolet shuns a hard-top and continues to favour the more traditional folding fabric arrangement - the hood can be opened or closed in 20 seconds at speeds of up to 25mph.

Porsche Cayman R (2010) first official pictures

This is the new 2010 Porsche Cayman R, the lightest and most powerful version yet of Stuttgart’s mid-engined sports car, and the closest it’s ever been allowed to get to the hallowed 911. Over and above the Cayman S, the Cayman R has a mere 10bhp more, taking the total to 325bhp – the torque figure is unchanged at 272lb ft. Much more impressive (and important) are the weight reductions: the Cayman R is 55kg lighter than the Cayman S.
