THE M HYBRID SYSTEM.
From race track to the road: 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 BMW M Hybrid V8 from BMW M Motorsport. The M HYBRID system in the BMW XM consists of a new V8 engine with M TwinPower Turbo technology and an electric motor integrated into the eight-speed M Steptronic transmission. Power is channelled to the road via the all-wheel-drive system M xDrive.
The powertrain delivers maximum output of 480 kW (653 hp) – generated by the combination of a combustion engine with up to 360 kW (489 hp) and an electric drive system with up to 145 kW (197 hp). Added to which, the first-ever plug-in hybrid model from BMW M GmbH also enables pure-electric driving over a range of 82 to 88 kilometres (51 - 55 miles) in the WLTP cycle. "You can assume that we will also find the drive in this or a similar form in other automobiles from BMW M GmbH", announces Franciscus van Meel, CEO of BMW M GmbH.
The BMW XM is the first electrified M automobile in the high-performance segment from BMW M GmbH, and more electrified models will follow the XM. Moreover, we are already working on the first all-electric high-performance model from BMW M GmbH.
NEW V8 ENGINE.
The BMW XM's new engine is a classically high-revving V8 with cutting-edge M TwinPower Turbo technology. The 650 Nm (479 lb-ft) of peak torque generated by the combustion engine alone is on tap between 1,600 and 5,000 rpm, and the V8 produces its maximum output of 360 kW (489 hp) at 5,400 rpm.
ELECTRIC MOTOR DELIVERS INSTANTANEOUS EMPATHIC POWER DELIVERY.
The V8 engine in the BMW XM is supported by an electric motor which is a product of fifth-generation BMW eDrive technology. The permanently excited synchronous motor is integrated into the eight-speed M Steptronic transmission and, in hallmark electric motor style, responds to just slight movements of the accelerator with emphatic power delivery. This takes the agility and dynamism of a high-performance car from BMW M to a new level.
The maximum system torque produced by the combination of electric motor and combustion engine is 800 Nm 590 lb-ft (engine with up to 650 Nm (479 lb-ft), electric motor with up to 280 Nm (206 lb-ft)). A pre-gearing stage is used to increase the maximum torque produced by the electric motor to 450 Nm (332 lb-ft) at the transmission input. This innovation enables the electric motor integrated into the transmission housing in a compact, weight-saving design to generate amounts of effective propulsive power that could normally only be achieved using a far larger unit. "Rarely have a concept vehicle and the resulting production vehicle been so close together. Of course, certain things are exaggerated in a show car, but the two vehicles are 90 percent similar", says Franciscus van Meel, CEO of BMW M GmbH.

THE SPORTS EXHAUST SYSTEM OF THE BMW XM.
THE SPORTS EXHAUST SYSTEM OF THE BMW XM.
Power delivery is accompanied by an energy-charged soundtrack of rare emotional appeal for an eight-cylinder unit. Providing the distinctive acoustics are two electronically controlled and continuously adjustable flaps in the sports exhaust system of the BMW XM. The exclusive character of the sports exhaust sytem is also reflected in the unique visuals created by the two pairs of dual tailpipes, the individual pipes arranged one above the other.
POWER ELECTRONICS AND HIGH-VOLTAGE BATTERY.
The optimised interplay between the combustion engine and electric motor is controlled in all model variants by the M HYBRID system’s power electronics. For example, intelligent energy management allows the battery’s charge level to be regulated so that the final stretch of a longer journey through a built-up area can be covered using only electric power.
The lithium-ion battery stands out with its high energy density at a cell and battery pack level. It provides a constant flow of power across a wide temperature range and even under the heavy loads brought by a particularly sporty driving style. It offers a usable energy content of 25.7 kWh.
The BMW XM is another highlight on the occasion of the 50th birthday of the BMW M brand. It is also the first M only vehicle since the famous and legendary BMW M1.
SMART CHARGING.
The Combined Charging Unit of the M HYBRID system enables AC charging at up to 7.4 kW.
The high-voltage battery can be replanished from zero to 100 per cent charge in 4.25 hours.
Predictive heat management reduces charging times by judiciously warming or cooling the battery.
The charging socket on the front side panel on the left-hand side of the BMW XM has a sensor that measures the temperature at the plugs contacts and can therefore detect a possible instance of overheating at an early stage.
The charging socket comes with the handy feature of a search light so that customers can also hook up their car to a power source in the dark without a problem.
Once charging is completed, the cable can be stored in a high-quality and stylish bag. Similar to a weekend-bag, this item is made exclusively for the BMW XM.
MORE TECHNICAL DETAILS ON THE BMW XM POWERTRAIN.
8-speed M Steptronic transmission with Drivelogic.
The eight-speed M Steptronic transmission with Drivelogic is a new development. It channels not only the power generated by the combustion engine but also the drive torque from the integrated electric motor as required to enhance either efficiency, comfort or dynamism. The hybrid module allows the car to move at walking pace without the driver pressing the accelerator and bringing the combustion engine into play.
Launch Control function.
The eight-speed M Steptronic transmission also has a Launch Control function to enable traction-optimised acceleration off the line with maximum dynamism. The optimally set shift points also help to ensure the best possible acceleration for all ambient conditions, e.g. the outside temperature and road surface.
Three driving modes.
The interplay between the combustion engine and electric motor in the BMW XM can be adjusted by selecting specific driving modes. HYBRID driving mode is the default setting and gives the driver access to the full system output of combustion engine and electric motor in tandem. In the Comfort setting, the electric motor is deployed to the full, optimising the efficiency of the BMW XM. If the battery is at a very low state of charge, the generator function feeds additional power into the high-voltage battery. This means the driver very often has the option of pure-electric driving. In the drive system’s Sport and Sport Plus modes, the combustion engine is permanently active.
In the ELECTRIC driving mode, the BMW XM uses only the power from the electric drive system, the eCONTROL mode offers the option to maintain the charge of the high-voltage battery during a journey or to increase it by means of energy recuperation.
M xDrive.
Supreme traction and captivating performance are the specialisms of M xDrive. In the BMW XM, this all-wheel-drive system splits the power generated by the combustion engine and electric motor between all four wheels precisely, quickly and as required at all times. An electronically controlled multi-plate clutch ensures fully variable distribution of power between the front and rear axle.
The rear-biased setup of M xDrive enhances the agility of the BMW XM. The system’s default mode is 4WD, but two other modes can also be selected via the M Setup menu as alternatives. In 4WD Sport mode, the proportion of drive sent to the rear wheels is increased once again to deliver particularly sporty, brand-typical handling in dynamic driving situations. And only when DSC (Dynamic Stability Control) has been fully deactivated can 4WD Sand mode be used. This setting initiates the traction-optimised wing of the all-wheel-drive system’s armoury and brings the locking functions of the M Sport differential – specifically conceived for driving over dunes and similar surfaces – into play.
M Sport differential.
Building on the work of the M xDrive all-wheel-drive system is an electronically controlled differential lock in the rear axle, which further enhances traction, agility and directional stability. The M Sport differential brings a need-based and fully variable distribution of drive torque between the left and right rear wheels. This helps to plant drive power firmly on the road without any losses, especially when the car is being pushed hard or has less grip on one side. Shifting power to the wheel on the outside of the corner nips understeer in the bud without the need for any brake inputs.
The M xDrive system and M Sport differential are linked up with DSC to ensure they all work together precisely as the driving situation demands. The BMW XM has a model-specific rear axle differential specially tuned to the extremely high system torque of its M HYBRID drive system.
BMW XM LABEL RED.
BMW XM LABEL RED.
BMW M GmbH will add the most powerful road-legal series-produced car in its history to the model range in autumn 2023, offering customers the ultimate performance experience. The V8-based M HYBRID drive system in the BMW XM LABEL RED elevates system output to a new high of 550 kW (748 hp). The maximum system torque of this model variant reaches 1,000 Nm (737 lb-ft) (generated by the combination of the combustion engine with up to 750 Nm (553 lb-ft) and the electric drive system with up to 280 Nm (206 lb-ft)).
Peak torque of the V8 rises to 750 Nm (553 lb-ft), which is sustained all the way from 1,800 to 5,400 rpm. Maximum output is generated at 5,800 rpm. These power figures and the precisely judged input of the electric motor represent a ticket to overwhelming performance characteristics.
