What the 2008 Chevrolet HHR lacks in top-rated comfort it makes up for in cargo and storage space.
In terms of passenger comfort, theCarConnection.com feels as if GM has dropped the ball; Automobile notes that "only the driver gets the more supportive, sport bucket seat (the non-matching, standard-style passenger seat preserves the fold-flat function)." Edmunds says that Chevrolet HHR 2008 "standard cloth buckets are not as comfortable as we'd like, but the optional leather seats are better cushioned and more supportive." Cars.com expresses the "wish [that] the HHR had a telescoping steering column so [one] could pull the wheel closer," adding "backseat comfort is only marginal...bench seat's bottom and backrest cushions are hard and the space is legroom-challenged." Car and Driver, conversely, praises the HHR’s “sofa-like rear seat.”
Where the 2008 Chevrolet HHR really shines, however, is in terms of storage and cargo capacity. "Considering its small exterior size, the HHR SS can swallow quite a bit of cargo," says Cars.com. “The boxy shape makes it roomy inside,” Car and Driver notes. ConsumerGuide reports "versatile storage space," remarking "it's easy to fold the 60/40 split rear seatbacks to create a flat load floor, but front seatbacks must be far forward for headrests to clear." Edmunds comments that "maximum cargo capacity is among the class leaders at 63 cubic feet."
The Chevrolet HHR won’t be lauded for its interior quality, though it fares better than some compact cars. "Most surfaces are textured enough to where they don't look especially cheap. SS models have slightly sportier trim that neither enhances nor detracts from the overall ambiance," according to Cars.com. On the other hand, Edmunds notes that "window buttons are awkwardly mounted behind the shifter, and some of the interior plastics are of mediocre quality." Edmunds also says, “Interior quality is among the best we've seen from General Motors, although it remains short of the caliber found in competing import vehicles.”
Sound levels are also a mixed bag, according to ConsumerGuide: "wind rush is well controlled, but engine buzz intrudes during acceleration. The turbo 4-cylinder whines, even under light throttle conditions. All [Chevrolet HHR] models suffer from noticeable coarse-surface tire thrum."
