Just a few months after the world premiere of the all-electric BMW i7, the drive portfolio of the new BMW 7 Series will be expanded to include additional engines in November 2022. Two plug-in hybrid models (PHEV) will be launched simultaneously in numerous automobile markets around the world, including the first BMW M automobile of the new BMW 7 Series, which will impress with the combined power of a six-cylinder in-line petrol engine and a further developed electric drive. Consistent electrification also optimizes the efficiency of the new BMW 740d xDrive, available on the European markets, whose straight-six diesel engine is supported by the latest 48-volt mild hybrid technology.
Plug-in hybrid drive : The new BMW M760e xDrive is characterized by particularly sporty performance characteristics and an extremely dynamic charisma. It is the first performance automobile from BMW M GmbH with a plug-in hybrid drive. The combustion engine is a 3.0 liter inline six-cylinder drive with M TwinPower Turbo technology, a rated output of 280 kW/380 hp and a rated torque of 520 Nm. Together with the new electric motor, it generates a system output of 420 kW/571 hp (with temporary boost) and a system torque of 800 Nm. The new BMW M760e xDrive accelerates from zero to 100 km/h in 4.3 seconds. The intermediate sprint from 80 to 120 km/h takes just 2.7 seconds.
In the new BMW 750e xDrive, the new electric drive is combined with a 3.0 liter inline six-cylinder engine with a rated output of 230 kW/313 hp and a rated torque of 450 Nm. Together, the two drives achieve a system output of 360 kW/490 hp and a system torque of 700 Nm. The new BMW 750e xDrive accelerates from zero to 100 km/h in 4.8 seconds. The intermediate sprint from 80 to 120 km/h is completed in just 2.7 seconds.
The electric motors of the two plug-in hybrid models draw their energy from a high-voltage lithium-ion battery integrated into the vehicle floor, which also belongs to the fifth generation of BMW eDrive technology. The usable energy content of the battery has been increased by more than 50 percent to 18.7 kWh compared to the previous generation. The maximum AC charging power is 7.4 kW. In conjunction with the high efficiency of the e-machine and the intelligent energy management including adaptive recuperation, this results in an electric range of 77 to 85 kilometers (provisional values) according to WLTP for the new BMW M760e xDrive and 78 to 87 kilometers according to WLTP for the new BMW 750e xDrive.

Diesel engine with 48-volt mild hybrid technology : Consistent progress within the framework of BMW EfficientDynamics also benefits the new diesel drive for the BMW 7 Series. An extensively further developed combustion engine is supported in the new BMW 740d xDrive by the latest 48-volt mild hybrid technology with an electric motor integrated into the 8-speed Steptronic transmission. This results in a maximum output of 220 kW/300 hp (generated jointly by the combustion engine with up to 210 kW/286 hp and the integrated electric motor with up to 13 kW/18 hp) and a maximum torque of 670 Nm (generated jointly by the combustion engine with up to to 650 Nm and the integrated electric motor with up to 200 Nm).
The latest generation of mild hybrid technology ensures that the additional power is provided particularly spontaneously and that there is a high level of recuperation to increase efficiency. The electric motor is housed together with its power electronics in the housing of the 8-speed Steptronic transmission, where it also functions as a crankshaft starter generator. The tractive power of the electrified drive that sets in early leads to a value of 5.8 seconds for acceleration from a standstill to 100 km/h. In addition, the precisely coordinated interaction of the combustion engine and electric motor promotes both the efficiency and smooth running of the drive system, which is therefore predestined for use in the new BMW 7 Series.
