BMW 5-series is in line for the company's new triturbo diesel engine

Details leaked from a dealer conference held in Holland this week suggest that BMW's upcoming 550dX will be the first recipient of the German carmaker's new high-tech triturbo 3.0-liter inline six-cylinder diesel engine. The new engine, which also is destined for the new X5 xDrive50d and X6 xDrive50d models, is claimed to produce 376 hp and more than 516 lb-ft of torque--some 70 hp and more than 74 lb-ft more than the most powerful version of BMW's existing twin-turbocharged 3.0-liter inline six-cylinder diesel engine, as found in the X5 xDrive40d. The radical new engine, which is rumored to use two traditional exhaust-blown turbochargers in combination with an electrically driven turbocharger to add low-end response, is planned to be offered exclusively with an eight-speed automatic gearbox and four-wheel drive.

Citroen DS3 WRC (2010): Loeb's new company wheels

This is the new Citroën DS3 WRC, just unveiled at the 2010 Paris motor show. And it’s the car that everyone interested in world rallying has been waiting for – it’s Sébastien Loeb’s wheels for the 2011 World Rally Championship. Okay, we know it’s not as highly anticipated as the Mini Countryman WRC, but the reason we’re excited is that this could be the car to end Loeb’s reign – the Frenchman has won the last six WRC titles, will almost certainly take his seventh this year, but having an all-new car will hopefully reset the field and give Ford’s Fiesta RS WRC a chance.
