Top Gear America is produced by one of BBC's satellite companies, but still being produced by the BBC. The only problem with the American Top Gear is the chemistry between the presenters. All three of them need to have some sort of chemistry between each other, like the three presenters on the BBC2 version. I also think they are relying on Tanner Foust's "pro racer" status and overusing it. The challenges somehow end up "i beat tanner". Besides the fact that the presenters seem to be forcing everything, the "Big Star Little Car" segment needs to get off of talking about people's cars and more about what they do as a professional. Thats the biggest difference between the UK and US guest star segments. The UK version will talk about the cars but it will also highlight why the person is famous as well.
My dream cast would be Jay Lenno, Anthony Bordaine, and Tanner Foust i think all three of those people would make a good team.
