Ferrari F150 (2013) first details on hybrid Enzo

After various leaks and rumours over the past few months, Ferrari – via its official customer magazine – has confirmed it will launch a new supercar to succeed the Enzo in 2013. It's been officially named as the Ferrari F150, and it will be powered by a V12 engine bolstered by a F1-style KERS hybrid system.

Citroen Survolt (2010) at the Geneva motor show

Citroen had a genuine surprise at the 2010 Geneva motor show – the sleek Survolt sports car concept. Well, the pair shared the same rotating plinth on Citroen’s stand but that’s about it.

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.
