Electric torque vectoring: A motor for each wheel or a single-motor-clutch system?
In February, engineering firm GKN Automotive announced a new torque-vectoring option for electric drive called eTwinster. Torque vectoring technology is generally defined as a vehicle’s ability to vary the power to each wheel. To quickly control the torque applied to the wheels independent of one another – increasing stability, responsiveness and agility – GKN’s new… Read more »
Xtrac’s new EV transmission system features dual motors with torque vectoring
Xtrac’s new P1227 gearbox family was developed to address the growing demand for single-speed, lightweight EV transmissions. It can be integrated with motors from BorgWarner, GKN and YASA, all of which worked with Xtrac to integrate their technologies into the transmission. The P1227’s dual electric motors provide inherent torque vectoring capabilities, and the system is… Read more »
NHTSA closes investigation of Model S fires, Tesla installs new shield for battery pack
The National Highway Traffic Safety Administration (NHTSA) has closed a three-month investigation of the Model S fire incidents, as Tesla announced a design change to better shield the car’s battery pack from road debris. Shortly after the fires, Tesla made a software update that raised the ride height of the Model S to reduce the… Read more »
