Powerful and efficient Ecotec engines are at the heart of the HHR. They provide good performance, value and convenience. Variable valve timing added to the base 2.2L Ecotec engine for '09 enables more efficient performance, along with an increase in horsepower from 149 to 155. This enhances the HHR's fuel economy, giving it a driving range of approximately 500 miles.

Also new for '09, the HHR's 2.2L and 2.4L Ecotec engines are FlexFuel capable. The HHR brings a turbocharged dose of thrills that is unmatched in the segment. For '09, the GM Performance Division has combined the SS's DNA with the unique HHR Panel to create a limited-edition HHR Panel SS.

The HHR SS is a high-performance vehicle like no other. Features such as "no-lift shift" and other driver-selectable performance modes help it achieve 0-60 mph performance in 6.3 seconds. A new SS Performance Package debuts in '09 and includes Brembo four-piston front brake calipers and a limited-slip differential.

In addition to the new HHR Panel SS model, variable valve timing for the 2.2L engine and E85 FlexFuel capability for the 2.2L and 2.4L engines, new technology and safety features highlight the cross-lineup changes for 2009, as well as the inclusion of some previously optional equipment as standard.
