The S-Class is the jewel in the German brand's crown. With sedan, convertible and coupe configurations, this imposing car is the pinnacle of comfort. Inside, silence reigns and every seat is throne-like. The engines range from the frugal S 550e plug-in hybrid to the insane 577- and 621-horsepower AMG variants. All-wheel drive is also available to help you get to your meetings, even in the worst storms.
