Mercedes-Benz Concept S-Class Coupe stars at the 2013 Frankfurt Motor Show

Mercedes is on a luxury drive here at Frankfurt 2013, displaying many different versions of its ‘best car in the world’ S-Class saloon, as well as this: the Concept S-Class Coupe.

Actually, whether to keep Maybach on the Daimler life support system is a question that has taxed the brains of many a Mercedes exec,  almost since the Maybach brand got its revival under Mercedes and turned in to a cross between a stretched old S-Class, a Playstation and a glitterball. Because despite the efforts of Mercedes to position the Maybach above the S-Class – and in to competition with Rolls Royce and Bentley – the Maybach has somehow conspired to be less desirable than the S-Class.
