The new BMW M5 has a total system output of 717 horsepower and 738 pound-feet of torque. This is achieved through a combination of a twin-turbocharged 4.4-liter V-8 engine, which produces 577 horsepower, and an electric motor, which adds another 194 horsepower1.
The new BMW M5 has six-piston calipers on 16.1-inch discs at the front, and single-piston floating calipers with 15.7-inch discs at the rear. Optional M Carbon ceramic brakes increase the front disc size to 16.5 inches and reduce weight by 55 pounds.
The xDrive system in the M5 has a unique feature that allows drivers to switch to rear-wheel drive. This can be done by selecting the Dynamic mode or by turning off the stability control, providing an even more unfiltered performance experience. Additionally, the system works in conjunction with an electronically controlled differential lock for the rear axle, which can send power left or right as needed for improved cornering and confidence.
