BMW reveals M diesel range

BMW has confirmed plans to launch M-division developed performance diesel cars in Europe by the end of this year.

Known as the BMW M Performance Automobiles, the new family will at first consist of a quartet of models – the BMW M550d xDrive Sedan, BMW M550d xDrive Touring, BMW X5 M50d and BMW X6 M50d – and are all powered by a newly developed six-cylinder in-line diesel engine that features three turbochargers providing maximum output of 381hp and peak torque of 740Nm.

The new six-cylinder is BMW’s most powerful diesel ever fitted to its models. The 2,993cc unit makes use of three turbochargers, and the size, arrangement and interplay strategy of the turbos have been designed to guarantee maximum power delivery across a wide rev band, says BMW. The system comprises two relatively small turbochargers and one large turbo, which join forces precisely to deliver the amount of power required. According to the driving situation, the low moment of inertia of the small turbochargers is exploited to the full to deliver razor-sharp responses, while the link-up with the large turbo is maximized to generate as much charge pressure as possible.

BMW says this innovative and unique multi-stage turbocharging concept represents an efficient method of boosting output. In addition, the efficiency of the new diesel engine is further optimized by innovations including a new development stage in common-rail direct injection technology, featuring piezo injectors working with maximum pressure of 2,200bar.

The BMW M550d xDrive Sedan accelerates from 0 to 62mph in 4.7 seconds, while the BMW M550d xDrive Touring covers the same sprint in 4.9 seconds. In the EU test cycle, the Sedan records fuel consumption of 44.8mpg, while the Touring comes in at 44.1mpg. CO2 emissions are 165 grams per kilometer for the BMW M550d xDrive Sedan and 169 g/km for the BMW M550d xDrive Touring.

The BMW X5 M50d accelerates from 0 to 62mph in 5.4 seconds, whereas the BMW X6 M50d does the same distance in 5.3 seconds, with average fuel consumption in the EU test cycle standing at 37.7mpg for the Sports Activity Vehicle and 36.7mpg for the Sports Activity Coupé. CO2 emissions are 199 grams per kilometer for the BMW X5 M50d and 204 g/km for the BMW X6 M50d.

Channeling such power is an eight-speed sports automatic transmission with enhanced gearshift dynamics and the xDrive all-wheel-drive system - tuned to suit the individual model and emphasize the traditional rear-wheel set-up of BMW cars.
