Mercedes is developing a high-performance four-door to compete with the Bentley Continental Flying Spur.
According to Autocar, the car will be sold alongside the CL and resemble an "über-CLS." It’s likely that it would have an even more dramatic shape than the coupe-like CLS and feature AMG engines.
Mercedes has decided to compete with Bentley and the upcoming Panamera GT of Porsche. In addition, there are rumors that the model could spawn a Maybach variant because the 62S Coupe has attracted much attention at the auto show.
