Blimey that's a nice sounding car! Looking forward to seeing it in full racing livery. Pity the rear arches don't look particularly good, doesn't actually look as good as the road car!
Can't really tell you what it sounds like because a) I can't remember, b) he was put in the gravel in Race 1 and didn't start Race 2 and c) when he was running, he was always in a pack of cars.
The C30 would be one crazy, hot car if the rear end wasn't so horrible. I like the rear's shape, but the tails need a redesign. The engine sounds crazy too. All 5 cylinder engines sound great though.
