Nikola and Bosch partner on hydrogen-electric Class-8 long-haul truck; dual-motor commercial-vehicle eAxle
By 2021, Nikola intends to bring to market the Nikola One and Two, a class 8 hydrogen-electric truck lineup that will deliver more than 1,000 horsepower and 2,000 lb-ft (2,712 N·m) of torque—nearly double the horsepower of any semi-truck on the road—all with zero tailpipe emissions, as previously announced by Nikola.

At the heart of the Nikola truck lineup is a new commercial vehicle powertrain achieved thanks to a development partnership between Nikola and Bosch. The organizations re-imagined the powertrain from the ground up. Bosch’s eAxle expertise (earlier post) has enabled Nikola to move quickly on an aggressive path to bring its electric truck to market.
The eAxle developed by Bosch is a scalable, modular platform with the motor, power electronics and transmission in one compact unit. This makes it suitable for vehicles of all kinds, from small passenger cars to light trucks. Nikola and Bosch will use this know-how to commercialize the world’s first true dual-motor commercial-vehicle eAxle for a long-haul truck.
The eAxle will use proven commercial vehicle electric machine technology and SMG (separate motor generator) motors from Bosch, and will realize what the partners call “unprecedented” targets for e-machine efficiency.
The eAxles will be paired with a custom-designed fuel cell system—also being developed jointly between Nikola and Bosch—designed to deliver benchmark vehicle range. The overall vehicle controls will also be jointly developed based upon Bosch’s vehicle control software and hardware. The Nikola Bosch zero local emission powertrain is designed to achieve segment-leading performance at a competitive total cost of ownership to traditional powertrains.
Bosch and Nikola will also jointly develop the overall powertrain system for the Nikola lineup, which will include the safety concept and vehicle electrical architecture.
