HHR is like a roving walk-in closet as this front wheel drive vehicle offers 57.7 cubic feet of space with the rear seats folded. (The front passenger seat can also be folded flat.) The hard-plastic load floor can be raised to provide a one-foot high shelf, and there’s hidden space via a five-inch recessed stow bin that lies beneath that floor. HHR hit the streets in the summer of 2005 as a 2006 model year vehicle. The 2007 vehicle stays with the same Ecotec 4-cylinder choices (a 2.2-liter and a 2.4-liter), but the engines gain power. The 2.2-liter goes from 145 horsepower to 149 horsepower, while the 2.4-liter goes from 171 horsepower to 175 horsepower. Built off the same platform as the Chevrolet Cobalt, the HHR captures some styling cues of the 1949 Chevy Suburban. HHR is sold in 2 trims, LS and LT with the LT having a 1LT package and a 2LT package. The vehicle provides a comfortable ride, and having a high roof (63-plus inches) means even tall people feel nicely accommodated. Sight lines are great. And the HHR – a take-off on its heritage high roof development codename – is stuffed with standards, including base features like cruise control, three power outlets, steering wheel controls, and a touchpad liftgate. The HHR with automatic transmission tallies up mpg estimates of 22 city/30 highway. MSRP of the up-level HHR LT with 2.4-liter 4-cylinder engine is $17,595.
