Compact versatile hatch meets retro two-door wagon in the HHR Concept. This concept’s two doors were stretched six inches, its B-pillars were leaned forward, and the windshield header was dropped four inches to give it a chopped look. The body and track are two inches wider in front, four inches wider in the rear. Under the hood is a supercharged 270-horse, 2.0-liter four. Performance exhaust and large brake rotors and calipers were installed. Also unique on this vehicle are the two-piece eggcrate grille with chrome surrounds and front fascia with billet air ducts.
