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.

Art installation moves 100,000 toy cars an hour

IT'S NO PICASSO, but this installation by conceptual artist Chris Burden certainly has the potential to be moving. Called Metropolis II, this amazing construction took Chris and his chief engineer four years to design and create and expands significantly on Metropolis I - the latest version has 18 roadways including one six-lane carriageway. It also has a rail network with HO-scale model trains, and running at capacity it pumps 100,000 cars around its network at a scale speed of 230mph.

Channel 4′s 4Car to close
