The HHR SS combines all of the style and capability of the popular HHR family with uncompromising performance, including a turbocharged and intercooled engine that produces 260 horsepower (194 kW), unique exterior styling and an SS-specific interior. The vehicle was developed by GM Performance Division (GMPD), with a team of engineers and designers dedicated to crafting nothing but high-performance vehicles.
"With its muscular stance, turbocharged power and track-capable handling, the HHR SS is a worthy addition to SS lineup," said Ed Peper, Chevrolet general manager. "It also reaffirms in a big way Chevy's commitment to the sport compact market."
Standard features include unique exterior appointments, with all-new front and rear fascias, new front grilles, a rear spoiler and 18-inch polished forged aluminum wheels wrapped with Michelin performance all-season tires. Inside, SS-embroidered sport seats - with ultra suede inserts - a new gauge cluster with 140-mph speedometer, an A-pillar boost gauge and a new, driver-oriented steering wheel and shifter support the serious driving capabilities.
Along with its high-performance attributes, the HHR SS comes standard with a host of safety and convenience features, including the StabiliTrak electronic stability control system and four-wheel disc brakes with ABS. Optional equipment includes side-impact air bags and a power-operated sunroof.
"This vehicle delivers all of the style, comfort and convenience found in the HHR portfolio, but also offers outstanding performance and versatility without sacrificing fuel economy," added Peper. "There's simply nothing else like it when it comes to four-door driving fun for the value."
The HHR SS arrives in dealerships in the fourth quarter of 2007.
An SS from the get go
The '08 HHR SS was engineered by GM Performance Division and is the first SS model developed since GMPD was charged with overseeing all of the "go, stop and turn" requirements demanded of any new Chevrolet wearing the SS badge.
"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."
To that end, 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 Nürburgring racing circuit. It includes specific stabilizer bars, spring rates and damper tuning - all designed to complement the turbocharged powertrain.
Consequently, the HHR SS delivers a sports car-like maximum lateral grip of 0.86 g (with manual transmission). The brake system is enhanced, too, with a four-wheel disc system and standard ABS. StabiliTrak electronically controlled stability control system is standard.
The HHR SS's performance rubber meets the road via Michelin Pilot Sport MXM4 P225/45R18 tires mounted on 18-inch polished forged aluminum five-spoke wheels.
The HHR SS is distinguished on the exterior with several unique features:
- New air dam-style front fascia with fog lamps
- New mesh-style upper and lower grilles
- New rear fascia with outlet for single bright exhaust tip
- Rear spoiler (mounted above rear glass)
- New rocker moldings
- Body-color door handles, mirror caps and rear license plate surround
- SS badges on the front doors and rear liftgate
Like the exterior, the interior is unique to the HHR SS, including SS-embroidered sport seats with ultra suede inserts, a specific gauge cluster, an A-pillar-mounted turbo boost gauge and a new shifter arrangement. Three interior color combinations are available: Ebony, Light Grey and Victory Red.
