Citro?´n today became the first manufacturer competing in the World Rally Championship to announce a hybrid drive WRC competitor. The C4 WRC HyMotion4 adds an electric kinetic energy recovery system to the C4 WRC. A 125kW electric motor generator is geared to the rear axle of the all-wheel-drive rally car while a lithium ion battery pack sits on top of the fuel tank. The motor-generator reduces brake wear and fade by providing regenerative braking capability. When the driver needs bursts of extra power for passing, a button provides instant electric boost. The driver can also enable an electric-only drive mode for use on road sections, particularly in urban or residential areas where noise is a concern. Citro?´n claims a increased range of up to 25 miles with the hybrid racer and reduced fuel consumption of 30 percent on road stages where the electric drive is used. Because rally cars run under so many different types of conditions all the different operating modes are driver selectable. Citro?´n hasn't given any hint yet of when or if they will try to run the hybrid WRC car in actual competition.
