BMW Group Prototype Production E Drivetrains – Video

BMW Group Prototype Production E Drivetrains – Video

The BMW Group is already developing the fifth generation of its electric drivetrain, for release in 2021, in which interaction between the electric motor, transmission, power electronics and battery have been further optimised.

A decisive advantage of this future electric drive is that the electric motor, transmission and power electronics are combined in a new and separate electric-drive component. With its compact design, this highly integrated new component takes up significantly less space than the three separate components used in previous generations. Its modular concept means that it is also scalable and can be modified for a wide range of different packages and performance levels, increasing flexibility and making it easier to install the new electric drivetrain component in different vehicle derivatives. Integrating the electric motor, transmission and power electronics into a single component uses fewer parts and therefore saves costs.

A further highlight is that the new electric motor does not require the use of rare earths, making the BMW Group no longer dependent on their availability.

The fifth-generation electric drivetrain also uses new, more powerful batteries. Their scalable, modular design means they can be used flexibly in the respective vehicle architecture at different production sites.

Thanks to further development of the battery in particular, the new electric drivetrain extends the range of pure battery-electric vehicles to up to 700 km. In plug-in hybrid models, distances up to 100 kilometres are possible. In this way, the BMW Group continues to expand its innovation leadership in this field.

With the electric motor and battery developed and produced in-house, the BMW Group already possesses a high level of core competence and value creation for electric drivetrains. In-house production gives the BMW Group a decisive competitive advantage, by securing know-how in new technologies, gaining important systems expertise and leveraging cost benefits.

The flexibility of the new electric drivetrain component and upgraded modular battery will continue to ensure the BMW Group’s freedom of action in the future. Thanks to the scalable electric modular systems, from 2020 it will be possible to fit all model series with any drivetrain, according to demand. The fifth-generation electric drivetrain achieves high levels of driving performance and good range with much less weight. It will be integrated into both front- and rear-wheel drive flexible enhanced vehicle architectures, which will also be suitable for all drive forms. This flexibility means the company will be able to meet the predicted demand for several hundred thousand electrified vehicles in 2025.
