2018 Mercedes-Benz S-Class S 560

The S-Class is Mercedes-Benz's flagship luxury sedan, also offered as a coupe and convertible, and it competes with the BMW 7 Series and Audi A8. The S-Class glides over pavement with a serene, controlled ride, and the powerful engines make it feel effortlessly quick when you need to pass. Inside, you get a lavish cabin with plush seats and high-quality materials, though the coupe and cabriolet have smaller trunks than the sedan. Expect premium fuel and pricey maintenance, but owners say the S-Class is worth the cost for the comfort and performance it delivers. Stepping up from the S 450 to the S 560 gives you the biturbo 4.0L V8, along with Nappa leather and the Burmester sound system as standard equipment. The 4.0L V8 makes 463 horsepower and 516 lb-ft of torque, paired with the nine-speed automatic and all-wheel drive, so it surges forward smoothly whether you're cruising or merging. Every S 560 gets the AIRMATIC air suspension with self-leveling, which keeps the ride silky over expansion joints and dips.
