Two-speed gearbox for electrified vehicles
2015 - PACE Award Winner
What: 2nd gear saves fuel for electrified vehicles
Innovation: The typical electric powertrain uses a one-speed electric-drive transmission, which takes the vehicle to a certain speed, then disconnects. GKN's two-speed eTransmission allows optimal powertrain performance with electric propulsion for high speeds, too. In the BMW i8, which goes from 0 to 60 mph in 4.4 seconds, the eTransmission, guided by innovative computer controls, stays engaged with the vehicle's six-speed automatic transmission up to the vehicle's programmed limit of 155 mph.
