HHR stands for Heritage High Roof. GM says the compact wagon's styling is a tribute to the '49 Suburban. The Chevrolet HHR is a competitor to Chrysler PT Cruiser, Toyota Matrix and Pontiac Vibe. The HHR is a compact four-door wagon and comes in three trim levels: LS, 1LT and 2LT.
Chevrolet unveiled the production model of the 2006 HHR, a unique vehicle that combines styling and interior adaptability to create a vehicle suited to all lifestyles.
