BMW explains its tri-turbo diesel engine

BMW has released a promotional video explaining how tri-turbochargers in the new 3.0-liter six cylinder diesel engine

BMW has released a promotional video for the tri-turbo 3.0-liter six cylinder diesel engine.

Although we have already learned a lot about the engine, this clip provides a good overview of the turbochargers. The video explains that “at low revs the first small turbocharger provides fast acceleration”. This is achieved by optimizing variable turbine geometry. The second turbocharger activates at medium revs to increase torque output. The engine’s peak output is 381 PS (280kW/375 bhp) at high revs. Additionally, the engine has a third turbo to boost its torque output of 740 Nm (546lb-ft).

The M550dxDrive sedan can accelerate from 0 to 100 km/h in 4.7 seconds. It averages 6.3 L/100km (44.8% mpg UK/37.3 mpg US), and emits just 165g/km CO2.

We have reported previously that the engine will be standard equipment in the company’s M Performance Automobiles lineup, which includes the M550d/Touring, X5M50d, and X6M50d. The M550d will go on sale in Germany on May 12th, while the X5/X6/M50d will begin arriving at dealers on June 16th.
