Though compact in size, the Chevy HHR features clever interior packaging solutions, including a split-folding rear seat, a fold-flat front passenger seat and a cargo area floor (with built-in grocery bag hooks) that allows it to accommodate bulky and/or long cargo items. For shoppers searching for a versatile compact wagon that's also stylish, the HHR certainly merits consideration. The Chevrolet HHR is a compact four-door wagon. Three trim levels are offered: LS, 1LT and 2LT. A passenger version is available in all trims, and there's also a two-seat panel van version that comes in LS and LT trims. The base LS model features full power accessories, cruise control, air-conditioning, keyless entry and a stereo with an auxiliary input jack as standard. The 1LT adds a power driver seat and a longer options list. Both the LS and 1LT are powered by a 155-horsepower, 2.2-liter inline-4, while the 1LT offers the option of a 172-hp 2.4-liter four-cylinder engine. The 2LT includes the bigger engine as well as 17-inch wheels, a firmer suspension and a premium stereo. All HHRs have antilock brakes, stability control and side curtain airbags as standard.
