The less-powerful BMW wants to outperform the Audi.
BMW and Audi fight for the same class of customers who want performance and luxury offered in a tightly engineered package. The two brands are notorious for trolling each other, but the battle for real superiority is often won on the track. Last year, Carwow discovered that the BMW M5 is quicker than the Audi RS6 Avant in a drag race, so it decided to see how the BMW M550i would stack up against the Audi super wagon.
The M550 is a step below the full-blown M model in BMW’s lineup, but it packs a potent powertrain. Under the hood is the same twin-turbocharged 4.4-liter V8 that powers the M5, though it’s tuned to make 530 horsepower (395 kilowatts) and 553 pound-feet (750 Newton-meters) of torque in the M550i. That’s less than the 600 hp (447 kW) and 590 lb-ft (800 Nm) of torque from the Audi’s twin-turbo 4.0-liter V8. However, the BMW is lighter by 352 pounds (160 kilograms).
