Besides the fact that the i8 would be better off dancing with the Cayman and others in their tier, 427CID is bang-on. Here’s how I tiered supercars. Shown above is tier 1-B, and below, should you choose to click further, is tier 1-A. Prices and ratings are entirely arbitrary; I made them up.

OK, so tiering the Huayra along with the Aventador and the F12 is pretty controversial, but I explicitly wanted to group the top V12-powered cars past the Ferrari Enzo together in one class, because V12 and nothing more.
