I only know that White Cat, Astro Robin, Space Angler, Blood Hawk and Twin Noritta are top tier (in my opinion at least). And Crazy Bear and Black Bull are by far the worst cars.
But, which positions would you put the rest of the cars?
As far as Time Attack is concerned:
Night Thunder is the best for the vast majority of tracks. It has A grade boost and the strongest drifting. Its jump distance is poor so other craft are used for big shortcuts.
Blood Hawk & Golden Fox have the next best drifting, but can jump further.
Twin Norrita has A grade boost and the second best jump distance.
Deep Claw has the best jump distance, it can do some shortcuts no other craft is capable of.
