It's not a copycat. That is the property that the BBC own, the Top Gear format.
I think 'copycat' does sum things up. It's a complete change of presenters, a different producer and there is really only one small change, the star in a car feature now is rallycross.
The existing format was the product of Andy Wilman (producer) and Jeremy Clarkson.
Episode 3 was a lot more reasonable, but episodes 1 and 2 may well have lost a significant percentage of the audience.
