The Chevrolet HHR (an initialism for Heritage High Roof) is a retro-styled, high-roofed, five-door, five-passenger, front-wheel drive crossover designed by Bryan Nesbitt and launched by the American automaker Chevrolet at the 2005 Los Angeles Auto Show as a 2006 model. The HHR shares the GM Delta platform with the Chevrolet Cobalt, Pontiac G5, and Saturn Ion. Chevrolet also marketed a panel van variant of the HHR beginning in 2007. Assembled in Ramos Arizpe, Mexico and marketed throughout North America, production of the HHR ended in May 2011. The HHR was replaced in the U.S. by the Chevrolet Captiva Sport. This was a rebadged version of the Opel Antara. However, the Captiva Sport was only available as a fleet vehicle and was not available new to the general public. Design The vehicle's design was inspired by the late-1940s/early 1950s Chevrolet cars and trucks, specifically the 1947 Chevrolet Suburban and Advance Design pickups, with large, square fender flares and a hemispherical grille. The design of the HHR has been credited to Bryan Nesbitt who was a former designer at Chrysler where he was the lead designer of the Chrysler PT Cruiser. Nesbitt was recruited by GM to join its design staff and served for a time as the chief designer of the Chevrolet brand. The HHR had a cargo-carrying capacity of . All models had a flat-load floor (passenger models have 60/40 split bench) and fold-flat front passenger seat. For the 2007 model year, it was available in four trim levels; LS, LT, 2LT, and Special Edition. A panel van variant was also made available in 2007 for only the LT trim and became available on all trim levels in 2008. A "Half Panel" (RPO code AA5) rear quarter window delete option was available in the 2008 to 2010 model years. Standard and optional features Every HHR came well-equipped with many standard features. These included power windows and door locks (front for the HHR Panel Van and front and rear for the standard HHR), dual front SRS airbags, a Driver Information Center, an A/M-F/M stereo radio with a single-disc CD/MP3 player and an auxiliary audio input jack, a four-speaker audio system, a tilt-adjustable steering wheel, keyless entry, cloth seating surfaces, a folding rear bench seat (for standard HHR models only), manually-adjustable dual (front) bucket seats, a compact spare tire and wheel, air conditioning, and a five-speed manual transmission.
