The relatively high power rating and copious amounts of torque (260 lb.-ft. of torque (353 Nm)) push the tuned HHR to 100km/h in just 6.3s. Sadly, this is for the manual transmission option only. Automatic models have their power reduced to just 235hp.
Unlike most sports models that are designed to go fast in a straight line but fall apart at a corner, the HHR SS has been enhanced with sports suspension, uprated brakes, and large performance tyres. GM honed the new model at the Nurburgring and customised the stabilizer bars, spring rates, and damper tuning for maximum performance. The 18in wheels are shod with Michelin Pilot Sport MXM4 P225 tyres to ensure maximum grip.
Outside, the HHR SS gets a new bodykit including front air-dam, mesh grilles, rear spoiler, and SS badging. On the inside, you get SS-embroidered sport seats, a new gauge cluster with 140mph speedometer, an A-pillar boost gauge and a sports steering wheel.
