2009 Chevrolet HHR E85 FlexFuel
The 2009 Chevrolet HHR small SUV will become the first four-cylinder model in General Motors Corp.'s North American lineup that can run on either gasoline or E85 ethanol. The HHR will become the latest Chevrolet FlexFuel model when it goes on sale later this year. Chevrolet has more than 2 million of GM's more than 2.5 million FlexFuel vehicles on the road. An HHR running on E85 - a blend of 85 percent ethanol and 15 percent gasoline - would emit up to 23 percent fewer carbon dioxide (CO2) emissions than if running on gasoline, based on a well-to-wheel analysis by the Argonne National Laboratory.
The HHR will be available with an Ecotec 2.2-liter or Ecotec 2.4-liter four-cylinder engine, both of which will be compatible with E85. For the first time, the Ecotec 2.2L is equipped with variable valve timing (VVT), technology that assures precise opening and closing of the valves and accurate control of combustion gases to improve engine performance and efficiency. The Ecotec 2.4L continues to offer VVT.
