The Gen 2 Voltec drivetrain has two motor/generators, two planetary gearsets, an abundance of clutches and the ICE. This allows the system to be used in five distinct drive modes ( http://gm-volt.com/2015/02/20/gen-2-volt-transmission-operating-modes-explained/ http://gm-volt.com/2015/02/20/gen-2-volt-transmission-operat... ). The all-electric range increase is proportionally greater than the battery capacity increase because the new drive system uses two-motor drive mode more often than the first gen drive system.
- Gravityloss 11y agoThis is very fascinating, new mechanical approaches proliferate! Koenigsegg has the total opposite approach in their hybrid Regera supercar: no gearboxes at all. Low speed high torque is delegated to the electric motors, and the internal combustion engine only engages after a certain speed. http://jalopnik.com/how-the-1-500-hp-koenigsegg-regera-hits-248-mph-without-1689181377 http://jalopnik.com/how-the-1-500-hp-koenigsegg-regera-hits-... I think that is a potentially fruitful approach.
