The G30 5-Series gets a major power boost after BMW recently revealed the diesel-powered M550d xDrive. It's the company's latest M Performance model that the company claims has the 'most powerful six-cylinder turbo-diesel in the segment'.

Available in both Sedan and Touring body styles, the M550d xDrive is driven by a 3.0-liter TwinPower Turbo inline-six. Compared to the previous engine which gets three turbochargers, the new motor has a total of four turbos. Two low-pressure turbines replace the large capacity third turbo.

With it, the 3.0-liter mill is capable of producing 400 PS at 4400 rpm along with a mighty 760 Nm of pulling power at 2000 rpm. This makes the 2017 M550d xDrive produce 19 PS and 20 Nm more than the older model. Power is then sent to all four wheels via an 8-speed automatic gearbox. 0 – 100 km/h is achieved in 4.4 seconds (4.6 seconds for the Touring) while top speed is electronically limited to 250 km/h.

Helping the M550d xDrive take on the corners are the M Sports suspension and the integral active steering system. It gets a 10mm reduction in ride height and delivers sharper handling according to BMW. 19-inch lightweight double-spoke alloy 664M wheels come as standard and are finished in Cerium Gray. The front axle gets 245/40 tires while the rear axle is equipped with 275/35 rubber.

As for its exterior, it comes with an M aerodynamic package which gives it a sportier appearance. On the other hand, the side mirror covers, radiator grill frame, and front and rear bumper elements are finished in Cerium Gray that contrast the bodywork. Also worth noting are the M Performance twin tailpipe exhaust pipes painted dark chrome and the brake calipers finished in metallic blue.

Inside, more M goodies make their way inside the diesel-powered Autobahn stormer. These include the pedals, footrest, steering wheel, optional M sport seats with Dakota leather or Alcantara upholstery and M Sports badging on the steering wheel.
