BMW has officiated the 2017 M550d xDrive, fitted with the most powerful diesel engine ever offered in a BMW 5 Series. The diesel-powered M550d joins its petrol-powered M550i sibling as the most powerful G30 5 Series in BMW's lineup.
The new 2017 BMW M550d xDrive is available in two body styles, sedan or touring. Both are powered by a 3.0-litre inline-six turbodiesel with four turbochargers, which made its first appearance on the 2016 BMW M750d xDrive. BMW says that the new M550d xDrive delivers 400 hp and 760 Nm to all four wheels via its xDrive all-wheel drive system. In comparison, the same engine in the M750d churns out an extre 40 Nm. By default, power delivery is biased to the rear wheels.
The Munich-based company said that the 2017 BMW M550d xDrive is available exclusively with an 8-speed automatic, allowing the new model to complete the century sprint in just 4.4 seconds. The heavier touring variant completes the same sprint in 4.6 seconds. Both models are electronically-limited to 250 km/h. In terms of fuel consumption, the M550d xDrive sedan returns 5.9 L/100 km, whilst the touring returns 6.2 L/100 km, both based on the ECE test cycle.
As the BMW M550d xDrive is largely similar to the M550i variant, it receives 19-inch BMW Double Spoke 664 M alloy wheels finished in Cerium Grey wrapped in 245/40R19 rubbers at front and 275/35R19 at the rear as standard. The side mirror housing, radiator grille housing, bumper elements and side air vents are also finished in Cerium Grey.
Completing the overall package is the standard M sports suspension, Integral Active Steering, M aerodynamics package, exhaust system with M Performance specific twin tailpipe trims in dark chrome and M sports brake with brake calipers finished in blue metallic with M engraving.
BMW has yet to annouce the official prices of the new 2017 M550d xDrive.
