The new 2018 BMW M550i xDrive lives up to the reputation of BMW being a driver’s car. The 2018 BMW M550i won’t leave you wanting more. The M550i is the quintessential BMW and good enough that you might not want to splurge for the M5.
The 2018 BMW M550i xDrive, which despite the badging isn’t a full-size M-car, but is, in fact, the top 5 Series you can purchase without going all of the way to the top shelf M5. Here you receive a lower, stiffer suspension, a sport exhaust, and beefier M Sport brakes, so it is more than just a name. It is actually faster zero to 60 mph than the outgoing M5 was.

2018 BMW M550i xDrive Standard Features
The M550i boasts incredible engine driving performance and efficiency. In this section, you’ll find the various engine, transmission, and aerodynamic features that make the 2018 BMW M550i xDrive one of the best driving sedans on the road today.
Performance and Efficiency Features
First, there’s the glorious engine. And for the 2018 4.4-liter BMW M Performance TwinPower Turbo V-8, 32-valve 456-hp engine. That means this M-Sport variant of the normal 5-series has two turbos with variable valve control (Double-VANOS and Valvetronic) paired with a cutting-edge direct injection system.
Here are some more features:
- Air Curtains and Air Breather system – provides an effective reduction in drag around the wheels.
- Sport exhaust system– A robust and aggressive-sounding upgraded exhaust system with dual outlets.
- Active kidney grille – Main benefits are engine cooling and aerodynamics.
- Electronic throttle control – No mechanical linkage, the accelerator pedal is electronically connected to the throttle.
- Auto Start-Stop function – Turns off the motor each time the vehicle comes to a complete halt – such as at traffic lights – and restarts it automatically. A reduction in fuel consumption is the result.
- Electronically controlled engine cooling (map cooling) – An optimal operating temperature is set according to “maps” stored in the Motronic Engine Control Module
- Brake Energy Regeneration – A system that only charges the battery when the vehicle is coasting, braking, or decelerating.
- Driving Dynamics Control with ECO PRO, COMFORT, and SPORT modes – boosts engine response from the accelerator, before changing gear and tightening the steering and chassis.
- 8-speed Sport Automatic transmission – Mated with Sport and Manual shift modes, steering wheel-mounted paddle shifters, and Launch Control
Handling, Ride, and Braking Features
While the 2018 BMW M550i sDrive sedan can carve canyons and rip around a racetrack, most of its time is spent on normal roads under normal driving conditions.

- Electromechanical parking brake – comprises the parking brake, starting-off aid, and emergency braking functions.
