Combining a potent twin-turbo V8 with hand-finished luxury details, the new GT63 S balances blistering performance with everyday usability, making it one of the most compelling high-performance sedans on the market today.
Bold Exterior with Athletic Presence
The 2026 GT63 S sharpens its fastback silhouette while maintaining AMG’s signature elegance. A wider Panamericana grille commands attention up front, flanked by LED matrix headlights and larger air intakes that ensure optimal engine cooling. Sculpted side sills, flared wheel arches, and new 21-inch forged wheels accentuate the muscular stance.
At the rear, a redesigned diffuser, quad exhaust outlets, and subtle ducktail spoiler add aggressive flair without compromising the car’s refined lines. The overall design conveys purposeful sportiness while retaining the premium aura AMG owners expect.
Luxurious Cabin Crafted for Drivers
Inside, the GT63 S showcases meticulous craftsmanship with Nappa leather, carbon-fiber trim, and microsuede accents. The driver faces a seamless widescreen digital cockpit that integrates instrument gauges and infotainment controls, while the center console features tactile metal toggles for key functions.
Front seats provide deep bolstering, full adjustability, and massage programs for long-distance comfort. Rear passengers enjoy generous legroom, dedicated climate controls, and heated seats. Ambient lighting, premium Burmester 3D audio, and AMG Track Pace integration reinforce the cabin’s high-tech, luxurious feel.

All-wheel drive with variable torque distribution ensures power reaches the road efficiently, supporting confident acceleration and cornering.
The exhaust features switchable flaps, allowing drivers to choose between refined grand-touring tones and an aggressive, performance-focused soundtrack.
Advanced Driving Dynamics
The GT63 S introduces refined AMG Dynamics systems for unprecedented control. Multiple drive modes adjust engine, suspension, steering, and differential behavior, while an AMG drift mode allows controlled oversteer for expert drivers. Rear-axle steering enhances low-speed agility and high-speed stability, and active roll stabilization reduces body lean without sacrificing comfort. Adaptive dampers fine-tune ride characteristics hundreds of times per second for a perfect balance between track sharpness and highway smoothness.
