General Motors isn't set to begin producing the new Chevrolet SS until early next year, but the company has recently been spotted testing the model on U.S. streets. Our spy photographers managed to click a few photos of a heavily camouflaged version of the sedan before engineers spirited it back into the relative safety of the automaker's facilities. Even so, those on hand could easily hear the bark and snarl of an impressive V8 propelling the machine around. Odds are that's a naturally-aspirated 6.2-liter lump behind the headlights, though GM was using a Cadillac CTS-V chase vehicle to keep pace, leading some to speculate as to whether or not the company may be considering a supercharged version.
Sounds like fun to us. We can clearly see a set of massive front brakes at work on the machine, however. After a closer glance, it looks as if the Chevrolet SS may roll out the door with six-piston calipers on hand, though the wheel spokes make visual confirmation a bit tricky. The shots also clearly show off a muscular set of dual exhaust and meaty rear tires out back.
While most of the nose is obscured by camo, we can see a set of LED daytime running lights peeking through the mesh. The Chevrolet SS will be built alongside the next-generation Holden Commodore in Australia beginning in 2013. Stay tuned for more information as it becomes available.
