The second vehicle, of course, is the most interesting. Perhaps as a way to justify future North American production of its cop car, perhaps simply because Chevy “gets it,” a civilized, civilian take on the PPV joins the model lineup next year. Wearing the SuperSport badge, the car will initially ride on the current Zeta platform and be offered exclusively as a four-door sedan. The SuperSport name and styling also will be applied to the 2013 Chevrolet NASCAR entry. The launch powerplant for the roadgoing car is expected to be the Camaro SS’s 6.2-liter V-8, pumping out something on the high side of 415 hp. A version of GM’s latest 3.6-liter V-6 will be added after the launch for the weaker of heart; we’d expect this engine to produce at least 320 hp. The SuperSport and the Caprice PPV will then migrate to the Zeta II platform in time for the 2015.5 model year. When this happens, full production will shift to North America, thereby delivering a much larger market for the cop version. In addition to the SuperSport sedan, a cropped-rear-overhang sport wagon and a Ute pickup are being considered for the North American market
