BMW is renowned for pushing back automotive boundaries and the new BMW X5 M and X6 M are two models that set a new benchmark.
As the first xDrive four-wheel drive cars, the BMW X5 M and the X6 M are a journey into new territory for BMW, while the twin-turbocharged 555 hp V8 engine heralds the launch of the most powerful road-going M car the company has ever launched.
The new range flagships to the X5 and X6 portfolio are both powered by the same 4,395cc twin turbocharged V8 engine producing a maximum power output of 555 hp at 6,000 rpm. Such prodigious performance equates to a zero-100 km/h time of 4.7 seconds, comparable to the critically acclaimed BMW M3.
Both the turbochargers and the catalytic converter are located within the vee of the powerplant. This arrangement results in an engine that breathes better and operates at a higher efficiency due to the shorter exit manifold.
Transmitting the power to the road in the X5 M and the X6 M is a drivetrain incorporating a new six-speed M Sport Automatic transmission, the class-leading xDrive four-wheel drive system and Dynamic Performance Control, all refined by M GmbH engineers to suit the new high performance vehicles.
Enhancing the package is the specification of Dynamic Performance Control on both vehicles. Dynamic Performance Control is a new style of differential, that first appeared on the BMW X6, which diverts power to the driven wheels rather than brakes the spinning wheel.
The X5 M and X6 M customer can fine-tune the chassis of their new vehicle for greater enjoyment. The customer can configure the Electronic Damper Control, Head-Up Display, Dynamic Stability Control setting and the degree of assistance from the Servotronic steering system.
