The all-new BMW XM is fitted with a newly developed plug-in hybrid drivetrain. The M HYBRID system in the BMW XM consists of a new 483-hp V8 engine with M TwinPower Turbo technology and a 194-hp electric motor integrated into the eight-speed M Steptronic transmission. Together, they generate a maximum system output of 644 hp at 5,400 RPM and 590 ft-lbs of torque between 1,600 and 5,000 RPM.

Power is channeled to the road via the M xDrive all-wheel-drive system. The combination of an electric motor and eight-cylinder engine produces immense, instantaneously available power sustained throughout the rev range. The M HYBRID system also enables purely electric driving with an anticipated range of 30 miles (estimated range of up to 30 miles according to preliminary BMW AG tests based on the EPA’s test procedure standards).

The BMW XM shares its drive concept of an eight-cylinder combustion engine supported by an electric motor with the newly developed endurance racing car from BMW M Motorsport. The BMW M Hybrid V8 will go racing in the IMSA WeatherTech SportsCar Championship in North America in 2023 at venues including Daytona. The following season, it will power BMW M Motorsport’s return to the FIA World Endurance Championship (WEC) and the 24 Hours of Le Mans.

The extensively updated, 4.4-liter engine utilizes the thermodynamic benefits of a cross-bank exhaust manifold. A reinforced crankshaft drive, further developed turbocharging – mounted close to the exhaust manifold and with an electrically controlled blow-off valve – plus a new vane-type oil pump and a weight-minimized plastic oil sump all play a role in increasing the engine’s efficiency. An optimized oil separation process with variable impactor enhances the engine’s emissions performance.

The VALVETRONIC fully variable valve control now includes a switchable rocker arm on the exhaust side, which allows the engines exhaust valves to be shut entirely. This way, when the driver releases the accelerator, a higher proportion of the braking energy can be fed into the high-voltage battery by means of recuperation.

BMW GEN5 electric motor.
The V8 engine in the BMW XM is supported by an electric motor which, like the plug-in hybrid system’s power electronics and high-voltage battery, is a product of fifth-generation BMW eDrive technology. The permanently excited synchronous motor is integrated into the eight-speed M Steptronic transmission and helps to provide quick throttle response.

The electric motor contributes up to 194 hp to the maximum system output of 644 hp. The maximum system torque produced by the combination of electric motor and combustion engine is 590 lb-ft. A pre-gearing stage is used to increase the maximum torque produced by the electric motor to 332 lb-ft at the transmission input. This innovation enables the electric motor integrated into the transmission housing to generate substantial levels of power that could normally only be achieved using a far larger unit. Developed by BMW, the extra gearing stage between the electric motor’s rotor and the transmission’s input shaft gives a boost to the M HYBRID system’s torque delivery. This torque is instantly on tap when pulling away and makes a clear difference both when accelerating off the line and passing at speed on the highway.

Aided by the grip of M xDrive and a sophisticated launch control system, the BMW XM accelerates from 0 to 60 mph in just 4.1 seconds. Top speed is electronically limited to 155 mph, or 168 mph if the optional M Driver’s Package is specified. The top speed in pure electric mode is 87 mph.

BMW XM Label Red.
Following the launch of the BMW XM in the first quarter of 2023, BMW M will reveal a special model in the BMW XM line-up: the BMW XM Label Red. The BMW XM Label Red will be the first in a series of BMW XM Label models, and available for a limited period of time. This special model will feature over 735 bhp and 735 lb-ft of torque, unique paint, wheel, upholstery, and trim selections, and an MSRP starting over $185,000. Production of the BMW XM Label Red is expected to begin in the Summer of 2023. Details on how to order the BMW XM Label Red will be available at a later date.
