Moin, you keep reading that there were development problems and that’s why you gave them up. Mercedes had tried it in the S-Class with a V18. VW tried it in the Bugatti with a real W18. Unfortunately, both were abandoned due to construction problems. Only I can’t find any details exactly what it was about. Just a W18 I don’t imagine so problematic – or at least less problematic in construction than a V18.
