Clutchless hybrid transmission concept for high-performance cars

An MIT student-inventor's clutchless hybrid transmission concept aims to provide high-performance vehicles an energy-saving attitude without compromise.

The concept mechanism uses an electric motor to fill the acceleration lag that occurs when a driver releases the throttle and engages the clutch. A second electric motor is used for quickly speed-matching the gears during the shift since there is no mechanical means to speed up the next gear before engaging it.
