CVT is Bosch's answer to upgrade EV efficiency

As electric vehicles (EV) move from niche offerings to mainstream products, research and development to improve all aspects of EV functionality and efficiency is accelerating. Bosch recently revealed results of an effort to improve one of the most crucial aspects of EV development - traction motor performance - by fusing electric motors with a transmission technology familiar to the internal-combustion world: continuously variable transmission (CVT).

Bosch revealed that coupling a lightly modified conventional pushbelt CVT it has dubbed CVT4EV with a typical EV traction motor can both improve performance and reduce energy consumption compared with today's typical setup of a traction motor integrated with a single-speed transmission. Fitted to a C-segment demonstration EV, Bosch said the CVT4EV improves acceleration and top speed and reduces torque demand on the traction motor, making it more efficient in many driving situations.
