2021 Mercedes-Benz S580 Performance and Engine

4.0L Twin-Turbocharged V8 Power

Under the hood sits Mercedes-Benz's legendary 4.0-liter DOHC V8 engine — the same platform found in AMG performance variants, tuned here for smooth, effortless power delivery. The S580 produces around 496 horsepower and 516 lb-ft of torque in stock configuration, paired with a silky nine-speed automatic transmission that shifts imperceptibly in daily driving. Whether you're merging onto I-75 or cruising down Woodward Avenue, this engine responds with authority and grace. The rear-wheel-drive platform (with optional AWD on the S580 4MATIC) delivers a balanced, driver-focused ride that belies the car's substantial size.

Mercedes-Benz S-Class Features and Interior

S-Class Executive Trim Appointments

The S-Class Executive trim is one of the most feature-rich configurations available on the 2021 S580. Buyers can expect the iconic MBUX Hyperscreen infotainment system, a massive curved display that spans the entire dashboard from driver to passenger. Inside, you'll find multi-contour massaging front seats, a Burmester 3D surround sound system, augmented reality navigation, ambient interior lighting with 64 color options, and rear-seat entertainment capabilities that make every passenger feel like a VIP. The 2021 S-Class was also the first generation to introduce rear-axle steering standard on the S580, dramatically improving low-speed maneuverability and high-speed stability — a genuinely transformative engineering feature.

Mercedes-Benz S580 Reliability and Ownership

What to Expect as an S580 Owner

The 2021 S-Class marked a full generational redesign, addressing many of the reliability concerns found in earlier W222-generation models. The W223 platform brought with it more robust software architecture, updated electronics, and an engine that has earned strong reviews from independent mechanics and owners alike. The 4.0L V8 biturbo has a proven track record across multiple Mercedes-Benz and AMG platforms. As with any luxury vehicle, staying current with Mercedes-approved service intervals and using OEM-quality parts is the key to long-term dependability. At just over 21,000 miles, this example is well within the window of its factory-designed service life, and many major service milestones are still ahead rather than behind.
