The 2008 HHR SS ia high-output turbocharged edition of its compact people hauler, engineered and developed by the GM Performance Division under John Heinricy. The HHR SS goes on sale in late 2007.

The heart of the HHR SS is a turbo 2.0-liter four-cylinder engine that makes 260 horsepower and is mated to a five-speed transmission massaged in Sweden by GM Powertrain.

GM Performance has developed an all-new FE5 sport suspension for the SS edition, complete with specific stabilizer bars, spring rates and damper tuning. Four-wheel disc brakes with ABS and stability control are standard. The car also gets 18-inch polished forged-aluminum wheels shod with Michelin Pilot Sport MXM4 tires.

The HHR SS features redesigned front and rear fascias, mesh-style upper and lower grilles, foglamps, new rocker moldings, rear spoiler and SS badging.
