2012 CR-Z Shown for demonstration purposes.
Hybrid Powertrain (IMA) Operation
The CR-Z is powered by Honda’s Integrated Motor Assist (IMA) System. It features an electric motor that adds power to the gasoline engine during acceleration and when going uphill. The motor also functions as a generator during deceleration, recharging the battery pack. The system also uses the motor for its “Auto Idle Stop” feature, which in most conditions, stops the engine when the CR-Z comes to a stop, and restarts instantly when the accelerator pedal is pressed. This innovation results in significant fuel savings during city driving.
