The front-wheel drive HHR Panel is available in two trim levels: LS and LT. A 149-hp 2.2-liter four-cylinder engine and five-speed manual transmission are standard on both trims. A 172-hp 2.4-liter four-cylinder engine is also available for the LT, and a four-speed automatic transmission is optional on all trims. The HHR Panel LS is equipped with 16-inch wheels, cruise control, air conditioning, satellite radio and MP3 capability; LT trims add a power driver's seat and a cargo net. An optional 2LT package outfits the LT with additional features that include a sport-tuned suspension, alloy wheels, fog lights and a leather-wrapped steering wheel/shift knob. Safety features on every HHR Panel include stability and traction control systems, 4-wheel anti-lock brakes, front airbags, overhead curtain airbags and a tire pressure monitoring system. The Chevrolet HHR Panel carries over with minimal changes for 2010. The performance-oriented SS has been removed from the trim lineup.
