hopefully ghosting is an option you can turn on and off, otherwise all of this would be talk for nothing. Except for the free-for-alls which could turn to grudge matches.
We've already seen people go a lap down in some of the demos. They get the blue flag waived at them and get smashed in to, but they haven't turned in to ghost yet.
Yes, that's what the white tires are, but the black suspension, transmission and engine also stand out.
Also rear differential.
You know, I was thinking that was the transmission, transaxle style, but you're right. If you look really close at the engine, it looks like there is a line between the engine and the (traditional) transmission.
