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.
