The Chevrolet HHR is a retro-styled, high-roofed, five-door, five-passenger, front-wheel drive wagon designed by Bryan Nesbitt and launched by the American automaker Chevrolet at the 2005 Los Angeles Auto Show as a 2006 model.

A retro-style automobile is a vehicle that is styled to appear like cars from previous decades. Often these cars use modern technology and production techniques. This design trend developed in the early 1990s and led to almost all automobile brands introducing models that referenced previous cars of the 1950s and 1960s.
