    Targa versus coupe

    There is a recent thread regarding a Targa with possible "track use" which I do not want to hijack so...

    Did the Factory ever publish any wind tunnel data or comparisons between coupe's and Targa's ??.

    To me the Targa has always looked somewhat awkward from many angles but this is only my personal feeling.

    I am aware that the Targa was well received especially in the warmer / sunny parts of the world and they are still produced which is wonderful.

    Thanks in advance.
