This show has no chance of matching the original.
Think of this way. Top Gear UK runs
WITHOUT commercials on BBC. They can give honest opinions on the cars without having to worry about some advertiser freaking out and pulling their ad money.
Top Gear USA is going to run on the History Channel win TONS of commercials. Do you think Ford will be happy if the US presenters rip the Mustang a new ***? How about Hyundai, Honda, Nissan, etc. Car manufacturers are going to want to run their ads on a show like this so don't expect accurate or even truthful reviews of the vehicles.
Its going to be like watching an hour long infomercial.
