Chances are if you’re not a part of the Corvette Racing team, you have no idea what the raw, fire-breathing C6.R sounds like. But if you went to last year’s Frankfurt Motor Show, chances are that’s the last thing you ever heard. Judging by the volume and the body language of the people in the video below, the sound of the C6.R was overwhelming, mostly in part because it was fired up indoors. After the revving session was finished, all that could be heard was applause. We’re not sure if the people in the video could hear the clapping at the time, though.
