CAR tech: how to eliminate turbo lag

CAR has tested a new breed of experimental super-diesel that literally leaves current technology standing and may banish turbo lag forever. We drove an Audi A6 3.0-litre V6 prototype fitted with an electric bi-turbo system which delivers a massive dose of torque from idle. The effect is radical, firing the saloon off the line like an R8 when the driver floors the throttle.

The Hamster wrecks his Morgan!

Richard Hammond has wrecked his Morgan Aeromax in a prang in Gloucestershire The Hamster was apparently on his way back from a flying lesson (look out for the Hamster and Captain Slow in flying washing machines in the next series of Top Gear, then) when a car braked sharply at a roundabout at Over, in Gloucestershire. The resulting four car shunt – with the Hamster at the back – ended up with much swapping of details, but no injuries. And Hammond came off least worse being at the back.

New Jeep Grand Cherokee facelift to get European debut at Geneva

The new Jeep Grand Cherokee will arrive at the Geneva Motor Show in EU guise in March ahead of a launch in the UK and Europe in the third quarter 2013. In all the ways that matter, the Jeep Grand Cherokee (which will be a 2014 model by the time it arrives in showrooms in the UK) for Europe is the same as that for North America, although it will have different engines, and just about all the shortcomings of the current Grand Cherokee have been addressed by the facelift. That means the cheap in places interior gets a good makeover to make the Grand Cherokee a more convincing place to be for European tastes, and the Atari-like Infotainment centre gets a proper makeover too to make it more 21st, and less 20th, century.
