Mercedes S-Class Coupe: Frankfurt 2013

The Mercedes S-Class Coupe (pictured) arrives in concept guise at Frankfurt The Mercedes CL was never really the big seller you might expect a coupe version of probably the best saloon car in the world – the Mercedes S Class – to be, But that could change with the new Mercedes S-Class Coupe, revealed today at the Frankfurt Motor Show as a concept. The Concept S-Class Coupe – which looks pretty much production-ready – comes complete with a new look, a look that reflects Mercedes’ recent design changes with a clear feel of a grown-up CLA in its lines. The long bonnet, raised line running from the front wings to the back wheelarch, no B-pillar, and a nose that takes the good-looking front of the CLA as its cue – but takes it a step further – makes the S-Class Coupe look like a proper Mercedes in its own right and not just a two-door version of the S-Class.
