The BMW M550d was arguably the best model in the last-generation 5-Series lineup. Created to bridge the gap between the normal 5-Series and the all-out M5, the M550d had a triple-turbo diesel inline-six that made gobs of torque. It was even offered in a wagon body style! It was perfect for those who wanted to fly under the radar while still having some fun-though it was never offered in America. The engine now makes 400 horsepower and 560 lb.-ft.
2018 BMW M550d xDrive Touring Review
Exterior and Interior
The M550d xDrive will come standard with a stiffer M sport suspension, active steering, an M aerodynamics package, and even M sport brakes. The wheels are 19-inch alloys with a staggered tire setup; 245/40 at the front, and 275/35 at the rear. In addition to the Touring body style, buyers can also opt for the more traditional sedan look-though we’re not sure why anyone would do that.
Inside it’s business as usual, with a leather M Sport steering wheel and BMW Connected, which includes live online services and sat-nav updates. This is in addition to the various assistance systems, which BMW says takes the 5 Series “one step further towards automated driving”. Leather or Alcantara sports seats feature on the options list.
Under the Hood
Responsible for the performance of the new 2017 BMW M550d is the world’s most powerful six-cylinder diesel in series-production. Four turbochargers pressurize the 3.0-liter in-line cylinder, allowing not only impressive response in the low speed range, but also a tremendous top performance at high speeds.
The power is transferred using ZF’s tried-and-tested eight-speed automatic transmission and a special rear-wheel drive xDrive, which adapts to the current driving situation with a fully variable force distribution. For maximum agility, the BMW M550d 2017 is also equipped as standard with the integral-steering linkage steering, which is also available for all other variants of the 5 Series G30/ G31 and supports the driving behavior with counter-steering or equal-steering.
Prices and Available
BMW say the M550d saloon will be available from July and the Touring at the end of the year, but we’ve not yet had confirmation the M550d is coming to the UK. Last year’s new 750d didn’t, but we can’t see BMW declining to offer the new M550d in its UK showrooms.
