What makes the M5 so fast?

The BMW M5's speed comes from a combination of factors. The current generation uses a twin-turbocharged 4.4-liter V8 engine producing around 600 horsepower, paired with an 8-speed automatic transmission and BMW's M xDrive all-wheel drive system, which puts power to the ground with minimal wheelspin. The all-wheel drive allows brutal acceleration from a standstill, helping it reach 60 mph in around 3.1 seconds. Beyond raw power, the M5 benefits from precise chassis tuning, adaptive suspension, and weight reduction measures that keep it agile despite being a full-size sedan. The combination of high output, advanced traction management, and aerodynamic refinement is what allows it to perform at supercar levels while remaining a practical four-door car.
