Once unique as a four-door coupe, forging new ground in style, the competition has filled in the segment with a bevy of alternatives.
The Audi A7, for example, is perhaps even more delightfully styled, and offers its own high-tech web-connected system, but is similarly expensive and only available with a supercharged V-6 engine.
The Infiniti Q70 is the low-price leader of this group, but instead of a high-performance option, Infiniti offers a hybrid version, though the interior and exterior are nearly a match for the Mercedes' opulence and style.
The Jaguar XF isn't a four-door coupe, but has its own unique style, and in XFR trim, can give the CLS63 AMG a serious run for its money.
Porsche's Panamera may seem an unlikely comparison, but its higher price brings far better rear-seat room and incredible performance, though the look won't please everyone's eye.
The Cadillac CTS-V is even faster than either the Jaguar or the CLS63 AMG, but is somewhat less luxurious--and less expensive.
