Honda CR-Z Mugen (2011): the first sketches

As with the previous UK-spec Civic Type R Mugen, this new Mugen model is currently being touted as a one-off prototype, but just as that Civic was then built in limited numbers the same may happen with the CR-Z – and the individual parts may become available as aftermarket accessories too.
