Mercedes-AMG S63 E Performance: 791 Hp Review For 2025

The Mercedes-AMG S63 E Performance stands as a monumental achievement in automotive engineering, fusing the refined elegance of the S-Class with the raw ferocity of AMG tuning. This plug-in hybrid sedan delivers a staggering **791 horsepower** from its F1-derived powertrain, propelling its substantial 5,700-pound frame to 60 mph in just 2.6 seconds while maintaining the serene comfort expected from a flagship limousine.

Powertrain Innovation: F1 Technology Meets Everyday Luxury

At the heart of the S63 E Performance lies a sophisticated plug-in hybrid system inspired by Mercedes’ Formula 1 efforts. The setup combines a hand-built **4.0-liter twin-turbo V8** producing 603 horsepower with an electric motor integrated into the 9-speed automatic transmission, adding 188 hp and 1,055 lb-ft of torque for brief bursts. This configuration allows for seamless transitions between electric-only driving, hybrid mode, and full gasoline power.

The **13.1 kWh battery** provides an electric-only range of approximately 20.5 miles, sufficient for short urban commutes in near-silence. Despite the hybrid setup, fuel economy remains modest due to the vehicle’s performance focus, prioritizing explosive acceleration over efficiency. Reviewers note the power delivery feels like a “leather-lined solid rocket booster,” with stomach-churning g-forces delivered in hushed cabin quietude.

Chassis Dynamics: Surprising Agility in a Behemoth

Despite its full-size dimensions—over 17 feet long—the S63 handles with the poise of a smaller sports sedan. Rear-axle steering effectively shortens the wheelbase, enhancing low-speed maneuverability and high-speed stability. The chassis tuning strikes a remarkable balance: **Michelin Pilot Sport 4S tires** achieve 0.96 g of lateral grip, enabling enthusiastic cornering without sacrificing ride comfort.

Adaptive air suspension with active roll stabilization keeps the body composed, even in Sport+ mode. Steering is precise and well-weighted, providing excellent on-center feel, though it filters out road texture for a more isolated experience. Braking is robust, with optional carbon-ceramic discs stopping the sedan from 70 mph in 161 feet and 100 mph in 330 feet. Early prototypes showed minor calibration hiccups like gearshift jolts, but production models have refined these for smoother operation.

• Key Handling Highlights: Rear-wheel steering for nimble turning radius.
• Active suspension absorbs imperfections while firming up for dynamic drives.
• Precise steering with progressive weight build-up.
• Exceptional stability at high speeds and in corners.

Interior Opulence: A Sanctuary of Sophistication

Step inside the S63, and you’re enveloped in S-Class luxury elevated by AMG touches. The cabin boasts **Nappa leather upholstery**, open-pore wood trims like fanned walnut, and metallic accents that extend to rear passengers. Front seats offer multi-way adjustments, rapid heating/ventilation, massage functions, and active bolsters—though some testers deactivated the latter for comfort during spirited driving.

Rear seating is limo-like, with individual chairs featuring screens, climate zones, foldable tables, and power leg rests. One rear seat even includes a folding footrest, rivaling private jet amenities. The **MBUX Hyperscreen** dominates with a 12.8-inch driver display, central touchscreen, and passenger screen, controlled via touch, voice, or steering wheel haptics. Dolby Atmos audio delivers immersive sound clarity.

Customization abounds: Manufaktur leathers, carbon-fiber steering wheels, and ambient lighting options allow personalization. Quad-zone climate, a massive panoramic roof, and self-leveling suspension ensure all-season comfort.

Design and Exterior Presence

The S63’s exterior exudes understated power with aggressive AMG styling: a wide stance, 21-inch forged wheels, and subtle aero enhancements. Paint options like Manufaktur Signature Olive Metallic or China Blue add exclusivity. Digital headlights project light patterns and welcome animations, turning heads with laser-like precision.

At idle, the exhaust is subdued, but activating the flaps unleashes a V8 growl that escalates to a full roar under load—perfect for those seeking drama on demand.

Technology and Driver Assistance Suite

Mercedes’ latest MBUX system powers an arsenal of tech: augmented reality navigation, gesture controls, and AI-driven voice assistance. Level 3-capable Drive Pilot (where legal) allows hands-free highway driving. Safety features include active emergency braking, lane-keeping, and 360-degree cameras.

The hybrid system’s energy recuperation is tunable, blending seamlessly with regenerative braking. However, electric mode’s short range limits its practicality for long EV-only trips.

Pricing and Ownership Considerations

Starting near **$190,000**, the S63’s price reflects its loaded standard equipment: massaging seats, Burmester audio, air suspension, and more. Options like carbon brakes ($8,950) or rear entertainment push totals over $200,000. Maintenance for the hybrid V8 may be costly, but Mercedes’ warranty and over-the-air updates mitigate concerns.

Compared to rivals like the BMW M8 or Porsche Panamera Turbo S, the S63 offers unmatched luxury with hybrid efficiency hints, though its weight and price set it apart as a statement of excess.

Real-World Driving Impressions

Daily drives feel effortless: silent EV mode for city streets, hybrid serenity on highways, and V8 fury for overtakes. The ride remains plush even in performance modes, transmitting just enough road feel for engagement without fatigue. Track testing reveals its limits—communicative chassis shines near the edge—but it’s equally at home cruising boulevards.

Passengers revel in rear-seat perks, making it ideal for chauffeured duties or family hauls. Fuel sipping is secondary; this is about presence and prowess.
