BMW M550d xDrive

The M550d is part of the M Performance Automobiles, a new BMW subsidiary, first batch of sporty cars that fill the gap between the full-fat M cars and normal BMWs.

They are aimed at those who want a normal Bimmer, but with a bit more spice. These super diesel models are also quite economical. The 5-series sedan version does 0 to 100 km/h in 4.7 seconds but it’s almost impossible to make it do less than 44 mpg.

That’s thanks to the new tri-turbo straight-six diesel engine under the bonnet that churns out 380hp and 750 nm of torque. The BMW M550d xDrive and BMW M550d xDrive Touring benefit, among other things, from the pace-setting efficiency of an eight-speed Sports automatic transmission with long high gears. As far as we can see it only has one major problem and that’s the starting price of 80,000 Euro which is a lot!


The sporting focus of the BMW M550d xDrive and BMW M550d xDrive Touring is highlighted by bespoke modifications to power transfer, chassis and design components. These upgrades bear the signature of BMW M GmbH, which uses its development expertise to mould the two models into extraordinarily harmonious overall packages. The outstanding power of the tri-turbo straight-six diesel engine is translated into thrilling driving dynamics with impressive precision. This allows the 5-Series-based BMW M Performance Automobiles to offer the driver not only supreme diesel power, but also remarkably agile handling and predictable, controllable responses when exploring their dynamic limits.

The BMW M Performance Automobiles come as standard with BMW xDrive to channel the engine’s power variably and as the situation demands between the front and rear wheels. The electronically controlled all-wheel-drive system works using a bespoke control strategy, which allows the threat of understeer in extremely dynamic driving situations to be counteracted by adjustments to the power split, without the DSC (Dynamic Stability Control) system linked up to xDrive having to intervene. The system’s M-specific tuning accentuates the traditional rear-wheel bias of BMW cars when it comes to power distribution.

The all-wheel-drive system of the BMW M550d xDrive and BMW M550d xDrive Touring sends more drive to the rear axle on the entry into a corner, delivering exceptionally precise cornering and impressive directional stability. In addition, the likewise standard Performance Control divides power between the rear wheels to maximise the cars’ sports performance. Carefully judged braking of the rear wheel nearest the inside of the bend coupled with a simultaneous increase in drive power ensure the car responds to the driver’s steering commands instantaneously and with high precision. The driver can even use the self-steering response typical of M cars to execute controlled drifts through dynamically taken corners.
