The "hotrod concept" (lower case) by Tristan Hipps looks aggressive, as all hotrods should, and it manages a sleek and smooth design. This of course goes well with the designer’s idea of blending classic hot rod roadster feel with a modern day form language. With power-train coming from Mazda’s formula race car, this is going to be one awesome hotrod. More specifically, power comes from a Mazda Rotary Valve engine mated to a six-speed sequential transaxle transmission to transfer power to the tarmac.
