Chevrolet looks to be prepping a turbo-powered HHR crossover with an “SS” badge, sourcing the Pontiac Soltice GXP’s turbocharged, direct-injection in-line four, which was rated at 260 hp and 260 lb-ft of torque (in the Solstice, at least). These shots of the HHR SS mule indicate the bowtie brand engineers are attempting to conceal the intercooler (look at the front bumper). Whether or not the turbo powerplant will make it into this HHR body style or a forthcoming, freshened version remains unclear at this point.
Although nearly all powertrains cross multiple platforms in today’s GM, Chevy has a special history with turbocharging. The 1962 Chevrolet Corvair Monza Spyder is generally believed to be the second widely-produced automobile with a turbocharger (the first being the the ‘62 Olds Cutlass Jetfire).
