Holden VF Commodore Calais V Concept

Holden has unveiled its new Calais V luxury sports concept, previewing the future design director of the carmaker's VF Commodore, which will be sold in the US as the Chevrolet SS. The halo car of GM's Australian arm is a clear evolution of the outgoing model, with an emphasis on greater percieved quality in order to appeal on a global scale. "You'll notice that the hood is more prominent, with a centre crease that emphasises performance potential and two raking spears sweeping in from the A-pillars," says Richard Ferlazzo Holden Chief Designer - Creative Design.

Future Audis may time traffic lights for you

Here's a trick efficiency-chasing hypermilers have been using for years: spotting the cycles of stoplights from 100 to 200 yards out and letting the car coast up to the light just before it turns green, then carrying on without ever letting the car come to a complete stop. These hypermilers, along with professional truck drivers, do this because they know that accelerating from a standstill burns the greatest amount of fuel, and because letting a car coast up to the light with the automatic transmission downshifting by itself is easier on the transmission than stomping on the brakes right beneath the stoplight. Oh, and it's easier on the brake pads as well.

McLaren P1 concept

The McLaren P1 concept – the company's flagship hypercar model – will make its world debut at the Paris motor show next week ahead of the production model some time next year. These first images reveal an exterior that's more expressive in its surfacing and graphics than the existing MP4-12C, with a particular motif made of McLaren's 'tick' logo through the DRG. Its bodywork also appears to be layered over the underlying carbon structure that appears around the nose, rear and door panel, which hint at the diagonal bar that ran through the F1's doors, although here it dives downwards rather than creating a wedge.
