what does hhr stand for in chevrolet
Heritage High Roof is what HHR actually stands for. It's pretty self-explanatory, but we get paid to fill this white space. By heritage, GM means the 1949 Chevy Suburban echoed in the HHR's bulldog face and baggy fenders. The roof actually looks low from the outside, thanks to pillbox windows seemingly cut by a hot rodder's torch, but it's not.
