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. Chevy introduced the HHR at the 2005 Greater Los Angeles Auto Show, the spiritual home of the custom car.

The HHR has a distinct design that fuses elements of the 1949 Chevy Suburban ? the original utility vehicle ? and the SSR roadster. It is built on the same solid platform as the new Chevy Cobalt. The HHR will be available in the second half of 2005.

HHR is a four-door vehicle with a rear touch-pad liftgate. Its high roof evokes the look of the innovative 1949 Chevy Suburban, while other exterior cues carry the expressive attributes of the SSR roadster ? all unmistakably Chevy traits.

Like the rest of the vehicle, the HHR?s interior combines the reassuring high visibility and cargo flexibility of an SUV with the comfort, appointments, driving ease and ergonomics of an upscale sedan. The high roof provides excellent headroom and creates a more open, airy environment, while the instrument cluster carries the heritage theme of the vehicle.
