• 2018 BMW M550i xDrive: Understated Monster, Fastest 5 Series Yet [Video]

    BMW’s M550i xDrive is the M car that’s not a M car

    On the mountain roads in rural Oregon, TFL’s Roman Mica discovered that the new M550i has the guts to be a super sports sedan.

    Here’s why this 550i deserves an M badge:

    • A 4.4-liter twin turbo V8 that pumps out 456 horsepower, 480 lb-ft. torque and is mated to an 8-speed transmission.
    • xDrive AWD with a rear-wheel bias to distribute all that juice to all four tires.
    • 0-60 mph time of 3.9 seconds (according to BMW) and a governed top speed of 155 mph, although we think 180 mph would be easy to hit with this car.
    • Sport-tuned suspension

    And here’s why this BMW doesn’t warrant M5 classification

    • No additional aerodynamic body work or spoilers.
    • No fat tires.
    • A comparatively quiet and relaxed ride.
    • A less-than-visceral exhaust note that grabs your soul and takes it for a ride.

    In short, TFL’s Roman Mica thinks it may be the most under-the-radar speed machine BMW’s put out yet. And those who drive it will know that subdued, luxurious looks can be deceiving.

    1. As the driver of a 2016 550i M Sport, I can tell you that the new 2018 must be brutally fast if it’s that much improved over mine. I look forward to upgrading in a few years.

      1. I had a 2012 BMW 528 2.0L Turbo, and after four visits to the dealership for engine and turbo issues over the four years I owned it I will never own a BMW again no matter what it is.

        I traded it in on a Lexus GS 350 last year and I am so so so glad that I did.
