Abstract
A drive system for a hybrid or electric vehicle that includes a transmission with three forward and three reverse gears. The transmission optionally includes a first and a second planetary gearset, a first and a second clutch, and a brake. The system may be configured to separately engage these components in concert. The drive system may include a single electric motor with a corresponding transmission, or multiple electric motors individually driving separate transmissions. Motors may be arranged upstream or downstream of portions of a transmission, and they may be aligned parallel with or perpendicular to a drive axle.
