2026 Mercedes-Benz S-Class S 500 4MATIC® Sedan in Peoria, AZ

How Does the 2026 Mercedes-Benz S-Class S 500 4MATIC® Sedan Perform?

Let’s just say—the 2026 Mercedes-Benz S-Class S 500 4MATIC® Sedan is not shy about showing off. This is the kind of sedan that feels equally at home gliding down city streets in Peoria or stretching its legs on open Arizona highways. Beneath its elegant exterior lies a powerhouse of engineering that blends intelligence with strength in ways few cars can match. Under the hood, the 3-liter inline-6-cylinder turbo engine with mild hybrid drive doesn’t just hum—it sings. Delivering 442 horsepower and 413 lb.-ft. of torque, this engine gives you quick, confident acceleration for highway merges or passing on two-lane roads. The twin-scroll turbo and electric auxiliary compressor make sure there’s no hesitation, just clean, instant power whenever you tap the throttle. And thanks to its Integrated Starter-Generator, the system adds an extra 23 horsepower when needed, even allowing for short bursts of gas-free coasting. The Hybrid Integrated Starter-Generator is also doing some serious multitasking. It powers key components, such as the water pump and air-conditioning compressor, that traditionally relied on belts. That means less weight under the hood and more efficiency. You’ll notice it when the sedan takes off quietly, or when it recaptures energy as you coast down a hill—smart engineering that doesn’t waste a drop of effort. The ECO Start/Stop system is another thoughtful touch, shutting the engine off at stoplights to save fuel and instantly restarting when you lift your foot off the brake. It’s like the S-Class knows exactly when to rest and when to get moving again. Shifts come courtesy of a 9G-TRONIC automatic transmission, which keeps the ride silky and quiet. Want a bit more control? Paddle shifters on the steering wheel enable you to handle gear changes yourself, while DYNAMIC SELECT offers modes ranging from ECO to Sport+, which adapt throttle response, steering, and suspension feel. Then there’s the AIRMATIC® suspension and Adaptive Damping System, constantly reading the road and adjusting the ride. Whether you’re hauling passengers or luggage, it keeps the car balanced and steady. Pair that with 4MATIC® all-wheel drive and electromechanical power steering, and the result is confidence in every turn, traction in every season, and grace in every motion.
