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.

Bentley designers talk 'Intelligent Details' in movie shot on iPhone

Bentley has released a short documentary featuring director of design, Luc Donckerwolke, and SangYup Lee, its new head of exterior design, taking a ride around New York City in the back of a pair of Mulsannes. Called 'Intelligent Details,' the film sees Donckerwolke and Lee talking about how one of the challenges of designing a successful Bentley interior is to match the car's performance with the expectation of its integrated technology. And to make sure you get the message loud and clear, not only does the video show the Mulsanne's optional smartly integrated iPads, which emerge from the front seat backs at the touch of a button, the whole movie itself was shot on an iPhone 5S (albeit 'enhanced' by some extremely expensive-looking lenses and rigs), then cut together on one of the car's in-built tablets.
