The 2009 Chevrolet HHR is a compact, retro-styled wagon available in four trims: LS, LT, SS, and Panel SS. The base LS and LT models come with a 2.2L four-cylinder engine producing 155 horsepower, while a 2.4L four-cylinder with 172 horsepower is offered for upper trims. The SS version brings more excitement with a turbocharged 2.0L four-cylinder engine that produces 260 horsepower. These power plants are mated to either a five-speed manual or a four-speed automatic transmission. Standard interior features include a six-speaker stereo, satellite radio, and an auxiliary port. The surfer-inspired design offers ample cargo space, comparable with some small SUVs. Safety was a priority even in 2009, with features like standard stability control, front-seat side airbags, and antilock brakes.
