7/10 C-
I have to say, having the Ariel Atom, a superbike and Tiff Needell, all made the show better for me. The "most powerful superbike" remark is kind of wrong, since I've seen the BMW rated with horsepowers at the crankshaft of 185, 190, 191 and 193. It probably is the most powerful 1000cc superbike. Both the Hayabusa and the Kawasaki ZX-14 have been rated in the same range or better.
The overuse of Porsches is getting a bit tiring, but what was done was interesting and the suspense buildup during the race was well done (it really seems like a Porsche should only be used if they release a completely new car, or if the Porsche is used as a measure for a car going up against it in a comparison test).
The Yeti review somehow lost its way, though it was nice to see a Skoda on the show. The Yeti review kind of brought things down, which is unusual for a Clarkson review. The rest of the show just wasn't very fluid and lost its flow somehow while going from one segment to the next.
Overall, I liked the content, but it definitely felt like it could have been better.
