There are several of these testing in the mountains near me. They sound really nice and are testing
alongside a few Aussie Holden Clubsport R8 and Commodore SS cars. The one Aussie driver of the
R8 said that the G8 is the same car which would mean it has the same engine, the 411hp LS3 (that's
in the R8 and the guy said they had the same engines). Here's a shot of one. Excuse the bad quality, but I was walking when shooting as the driver was giving me the eye. This car does have
the ram air hood.
