All over the web in the middle of the week of 21 April is this recent footage of a prototype 2010 Camaro Coupe being tested at the Nurburgring in Germany. The car is undisguised, as have been all Camaros seen in public since GM decided in '07 to dispense with keeping the car's appearance a secret.

Nurburgring's "Nordschleife", or "Northern Loop" is a 13-mile test facility in Germany, notable for its length, dizzying number of turns, significant elevation change and that, at times, is open for public use, is popular with car companies world-wide for development and testing of the ride and handling of future, high-performance models. GM has been testing performance cars (notably the Cadillac CTS-V, Corvette Z06, the coming 2009 Corvette ZR1 along with the fifh-gen Camaro) there since early this decade.

It is likely, considering the huge wheel/tire package and the Brembo brakes, the car in this video is a prototype of the Camaro SS model. We'll guess it's got a 425-hp LS3 and a Tremec six-speed manual trans. Edmunds' audio on the tape implies that the headlamps and tail lamps are not production-intent. To us, the tail lamps seem ok, but the headlights are kind of dorky-looking. Other than that, we like what we see. As for how the car sounds, it seems kind of quiet. But, hey...we're hardcore and we like the exhaust loud. With the introduction of this car still about a year off, GM still has time to change those things.
