Abstract
A vehicle is provided. The vehicle includes an engine, an electric machine, an electric heater, and a controller. The electric machine is configured to recharge a battery through regenerative braking. The electric heater is configured to heat an engine coolant. The controller is programmed to redirect regenerative braking power to the electric heater in response to the engine coolant temperature being below a threshold.
