Continuously Variable Transmission (CVT)
Every 2010 Civic Hybrid is equipped with a continuously variable transmission (CVT). Similar to an automatic transmission, CVT substitutes the gears found in more traditional transmissions and replaces them with a metal push-belt running between a pair of variable-width pulleys. Combined with the Drive-by-Wire throttle system, the CVT constantly adjusts to provide the most efficient drive ratio possible depending on torque load. Honda CVTs provide better fuel efficiency and acceleration when compared to a conventional transmission.
