GM has been awfully quiet regarding the 2014 Chevy SS sedan, which is basically a top-of-the-line Holden Commodore imported from Australia. Most likely that is because even internal sales projections are fairly low, with volume estimated to be between just 2,000 to 3,000 units annually. But that doesn’t mean we still don’t want one in our driveway.
Hennessey Performance was lucky enough to get their hands on one, putting in onto their DynoJet chassis dyno to get the most accurate ratings possible. No surprises here, as the Chevy SS consistently makes the same power as the Camaro that it shares its engine with.
DynoJet is the standard many tuners use because of its inherent accuracy in measuring horsepower that goes directly to the road. Hennessey has dynoed a variety of vehicles, including the 2014 Chevy Corvette, and the results are always consistent, and depending on the model, the Dynojet can handle upwards of 2,000 horsepower at simulated speeds of 200 MPH.
Of course a stock Chevy SS isn’t making anywhere near that sort of power, and Hennessey came away with a reading of 359 horsepower and 367 pound-feet of torque at the wheels. Like we said, right on par with automatic-equipped Camaros, though we imagine once Hennessey is done with it, the power will push the DynoJet quite a bit harder.
