In the future, any vehicle carrying the SS designation will offer more performance than the standard models of the same vehicles from Chevrolet. The SS models will have more horsepower, different brakes and different tires as well as different styling cues, Lutz said.
The Corvette Z06, however, won't be incorporated into the new SS family, he said, but with Chevrolet building its global presence, he would like to see the designation spread from the U.S. to overseas markets.
Culturally, however, it could be difficult because the term "SS" has a much more sinister connotation in Europe where it was the designation for special troops deployed by the Nazis during World War II, making it difficult to use commercially, Lutz noted.
However, GM is charging ahead with remake of the SS line, he said. Chevrolet showed off the latest version of SS family, the 2008 HHR SS, during the Woodward Dream Cruise last summer in Detroit. Lutz said the specifications of the HHR SS illustrate where Chevrolet intends to move with the SS badging.
The ’08 HHR SS was engineered by GM Performance Division and is the first SS model developed since GMPD was charged with overseeing the “go, stop and turn” requirements demanded of any new Chevrolet wearing the SS badge, Lutz said.
“Beginning with HHR SS, all future SS models will have superior power, braking and handling capabilities for maximum credibility with our customers and enthusiasts alike,” said John Heinricy, GM Performance Division executive. “The SS badge represents high performance, and the HHR SS delivers with a fully-integrated, balanced driving experience.”
The next car to get the SS upgrade is the Cobalt, a member of Heinricy's engineering team said. The new Cobalt SS is due out in the spring of 2008.
The HHR SS is transformed by a turbocharged and intercooled engine that produces 260 horsepower and an specific interior, which was developed by engineers and designers from the GM Performance Division. The changes in the HHR interior include everything from sports seat with SS embroidered badge to moving the shift lever 6 millimeters, making it easier to manipulate the manual transmission.
Standard features include unique exterior appointments, with new front and rear fascias, new front grilles, a rear spoiler, 18-inch polished forged aluminum wheels wrapped with Michelin performance all-season tires and a new gauge cluster with 140-mph speedometer, an A-pillar boost gauge and a new, smaller, 14-inch, driver-oriented steering wheel and shifter.
Lutz said the HHR SS was engineered to offer more than simply increased power. An all-new FE5 Sport suspension was developed and tuned at Germany’s famed Nurburgring racing circuit. It includes specific stabilizer bars, spring rates and damper tuning – all designed to complement the turbocharged powertrain. The HHR SS has maximum lateral grip of 0.86 g (with manual transmission) and standard anti-lock brakes.
