Both the E85 version and the conventional gasoline engine version use a 10 kwh lithium-ion battery, which allows for a range at or less. When the battery's charge drops to 30%, the vehicle switches to its four-cylinder engine, assisted by the batteries, operating as a regular hybrid electric vehicle. The vehicle has a display system that shows the driver how efficient the vehicle is at any given time. If the vehicle uses its engine and is running in traditional hybrid mode, fuel economy is rated at in the city and on the highway.
