This elegant beast comes equipped with the powerful and strong 4.4-liter, twin-turbo V8 premium unleaded engine which transfers around 423 hp of max power and 553 lb-ft of max torque to its wheel. The powerhouse is the same as the last year’s one and it still makes the BMW M550i xDrive a hell of a beast and to match its power and torque figures, BMW grants it with an 8-speed Sport automatic transmission.
The xDrive all-wheel-drive system maintains a proper amount of power in every wheel of the car and with the aid of transmission & drivetrain system, the engine accelerates the car from standstill to 60 mph within just 3.6 seconds whereas the M550i xDrive completes the quarter-mile sprint in 11.8 seconds.

How does the 2021 BMW M550i xDrive handle?
BMW has always been known for its raw performance and sporty driving dynamics, which it certainly shows through its 523 hp engine and the 0 to 60 mph acceleration timing of 3.6 seconds. This sports sedan beats many exotic supercars in terms of driveability and it also comes at a very reasonable price tag too. The steering wheel is very responsive to high-speed maneuvering and keeps the vehicle stable on curves.
The suspension system of BMW M550i xDrive is on a stiffer side and it’s necessary too, to handle all the power its engine produces and it also keeps the body roll to the minimum at high speeds. Due to a stiffer suspension setup, the BMW M550i doesn’t seem to handle well on rough roads and doesn’t absorb bumps very well. FRont seats are very comfortable though but rear seats feel a bit cramped for tall passengers.
