This massive 2-door is actually an S-Class coupe, a name that was adopted when Mercedes launched a new generation in 2014. This SEC was unveiled in Detroit in early 1992 and marketed in autumn, that same year. This 600 version was equipped with the 6-litre V12 (408 hp). This Mercedes coupe was then almost as powerful as the Ferrari 512 TR (422 hp), the upgraded version of the Testarossa!
