Watch 'The Million Dollar Mustang' part one: Shelby GT350 R

“The Million Dollar Mustang” is not about how much these great cars go for at auctions in today's heady times, but about what made them worth so much in the first place. Nearly five years in the making, the documentary starts out talking about the Ford Mustang in general, how they sold 22,000 of them on the first sales day and then sold a million of them in the first two years and things like that -- the notion that the Mustang was a revolution in American car design and in the American consciousness. Then it starts to narrow its focus more and pretty soon the bulk of the piece is all about the Shelby GT350 R.

Porsche Cayenne S Diesel: The V8 diesel Cayenne arrives

Porsche has revealed the 2013 Cayenne S Diesel with a 4.2 litre V8 diesel offering 378bhp, 626lb/ft of torque and 0-62mph in 5.7 seconds. Back in April we reported that the Porsche Cayenne S Diesel was on its way with a V8 diesel engine to take on the BMW M50d and the upcoming offerings from Land Rover with a 2014 4.4 litre Range Rover Sport seeming a likely possibility. Now Porsche has caught up and revealed the Cayenne S diesel, which gets the 4.2 litre diesel V8 with a healthy 378bhp and a very useful 626lb/ft of torque, enough to scoot the Cayenne S Diesel to 62mph in 5.7 seconds – a bit slower than the M50d, but all that torque should make it feel at least as lively.

An evolution of the Microbus concept unveiled ten years ago, the Bulli is Volkswagen's T1 renaissance. The Bulli is yet another electric concept that graced the floor in Geneva, boasting a range of around 300 km to a single charge from its 85 kW motor. The two tone exterior, complete with oversized VW emblem is a direct nod to the T1.
