2 Answers
The differences between the BMW M550i and M5 are as follows: 1. Different Powertrains: The BMW M5 is equipped with an M TwinPower Turbo S63 4.4-liter V8 twin-turbo twin-scroll gasoline engine, delivering a maximum output of 600 horsepower (DIN) and a robust torque of 750 Newton-meters. The BMW M550i, on the other hand, features a 4.4-liter V8 gasoline twin-turbo twin-scroll engine, producing 530 horsepower and 750 Newton-meters of maximum torque. 2. Different Chassis Configurations: The BMW M550i comes with an xDrive intelligent all-wheel-drive system and an M Sport differential, which can distribute 100% of the engine's power to the front and rear axles based on road conditions, and allocate torque between the rear wheels for optimal traction. The BMW M5 features teardrop-shaped M mirrors designed with aerodynamics in mind to reduce drag coefficient. The body structure is constructed using lightweight CFRP (carbon fiber reinforced plastic) composite materials, which are stronger than steel. The front double-wishbone and rear multi-link suspension components are forged from aluminum alloy.
Speaking of the difference between the BMW M550i and the M5, as a long-time BMW owner who has driven many models, I think the most obvious distinction lies in performance. The M550i is quite powerful, but it feels more like a high-end version of the 5 Series, equipped with a V8 engine producing around 500 horsepower—fast in acceleration but leaning toward daily comfort. On the other hand, the M5 is a true M-series beast, featuring a high-performance engine with power soaring above 600 horsepower, 0-60 mph in under 3 seconds, paired with a reinforced chassis and an all-wheel-drive system that delivers a full-on track experience. The M5 feels more aggressive to drive, with sharper brake response, though it might feel a bit stiff for daily use and consumes significantly more fuel. Price-wise, the M550i is much cheaper than the M5, making it better suited for those who love BMWs but don’t chase extreme driving. In short, the M550i is for practicality, while the M5 is a speed enthusiast’s dream machine.
