The 2011 Chevrolet HHR is a compact five-door wagon, available in LS, LT, and SS trims. It features a FWD drivetrain with two engine options: a 2.2-liter four-cylinder delivering 155 horsepower and a more powerful 2.4-liter four-cylinder with 172 horsepower. Both engines utilize a 5-speed manual transmission, with a 4-speed automatic being optional. The HHR promises a smooth and comfortable ride with a retro-inspired design. The interior amenities vary by trim, but all models come equipped with an AM/FM stereo, CD player, MP3 playback, and satellite radio capability. On the safety front, the HHR includes antilock brakes, stability control, and numerous airbags. Unfortunately, this model year precludes connectivity technologies such as Apple CarPlay and Android Auto.
