The 2009 Chevrolet HHR lineup receives a host of changes, including more standard power, the ability to run on E85 ethanol-blended fuel, and some new features. This compact wagon is named for its "Heritage High Roof" styling inspired by 1950s Chevrolet Suburbans. HHR is front-wheel drive and shares some of its basic design with Chevy's Cobalt. Most HHR models seat five, but Chevy also offers a two-seat "panel" version that targets delivery companies. Regular and Panel models come in LS, LT, LT, and high-performance SS trim levels. The SS Panel is new for 2009. LS and LT have a 155-hp 2.2-liter 4-cylinder engine, which an increase of 6 hp over 2008 models. Optional LT is a 172-hp 2.4-liter 4-cylinder. Both these engines are now capable of running on E85 ethanol. The SS has a turbocharged 2.0-liter 4-cylinder engine that produces 250 or 260 hp depending on transmission selection. SS versions have a specific sport suspension, 18-inch wheels, and unique trim. A 5-speed manual transmission is standard and a 4-speed automatic is optional on all HHR models. Available safety features include ABS, traction control, antiskid system, and curtain side airbags. Newly available on the 2009 HHR is a wireless cell phone link. A rearview camera is due later in the model year.
