Mercedes-Benz’s flagship sedan is also one of its most iconic cars. The S-Class offers by far one of the most opulent and comfortable interiors you can find. In fact, it takes luxury to new heights with the Maybach models, which feature either a 496-horsepower V8 or a 621-horsepower V12. Meanwhile, the AMG S E Performance plug-in hybrid model produces 791 horsepower and can travel 26 km in pure electric mode.
