2027 Mercedes-AMG S63 Release Date: Latest Updates – The high-performance flagship of the Mercedes-Benz S-Class lineup is drawing strong interest among U.S. luxury buyers. While the refreshed 2027 S-Class (non-AMG models) has already been revealed and is arriving at American dealerships in fall 2026, the more powerful Mercedes-AMG S63 remains in the final stages of development.
Expected 2027 Mercedes-AMG S63 Release Date
As of mid-August 2026, Mercedes-AMG has not yet officially unveiled the updated S63. Credible automotive sources report that the model is expected to debut in the second half of 2026, with U.S. sales likely following in late 2026 or early 2027 as a 2027 (or possibly early 2028) model-year vehicle.
Spy photographs of near-production prototypes first appeared in late January 2026, shortly before the regular S-Class reveal. Additional testing continued into 2026, including recent sightings in southern Europe. Industry observers note that AMG typically launches its performance variants several months after the standard models, allowing time to refine the more aggressive powertrain, chassis, and exhaust systems.
The standard 2027 S 500 and S 580 reach U.S. dealers in the third quarter of 2026, with the plug-in hybrid S 580e arriving later in the year. The AMG S63 is expected to follow a similar staggered rollout pattern once officially confirmed.
Design Updates Visible in Spy Shots
The 2027 S63 will adopt the same mid-cycle refresh applied to the rest of the S-Class family, which Mercedes describes as involving more than 2,700 new or revised components. Exterior changes remain evolutionary rather than revolutionary.
Spy images show a Panamericana-style grille exclusive to AMG models, revised front bumper with larger air intakes, updated LED headlights featuring star-pattern elements, and minor rear detailing. Camouflage still hides some final details, but the overall silhouette stays true to the current W223 generation while incorporating the more upright grille and lighting signatures of the facelifted range.
Powertrain and Performance Expectations
The biggest change centers on the engine. The previous-generation S63 E Performance used a complex plug-in hybrid system pairing a twin-turbo 4.0-liter V8 with a rear electric motor for 791 horsepower and more than 1,000 lb-ft of torque. Reports indicate the new model will switch to the latest M177 Evo flat-plane-crank 4.0-liter twin-turbo V8, the same family of engine already confirmed in the refreshed S 580 and in the 2027 AMG GLE 63 S / GLS 63.
This evolution features larger turbochargers and a flat-plane crankshaft for sharper response and a more distinctive exhaust note. Output figures have not been confirmed, but the S 580 version already produces 530 hp. The AMG-tuned version is widely expected to deliver substantially higher figures, potentially approaching or exceeding the previous model’s peak power while shedding the weight and complexity of the full plug-in hybrid system. A mild-hybrid setup with a 48-volt system is considered likely.
All-wheel drive (4Matic+) and a nine-speed automatic transmission will remain standard. Enhanced rear-axle steering (reportedly up to 10 degrees) and updated air suspension with intelligent damping are also anticipated.
Interior Technology and Features
The cabin will receive the same major technology upgrades as the standard 2027 S-Class. These include the latest MB.OS operating system, an expanded Superscreen or Hyperscreen display setup, an AI-powered assistant, and improved materials and ambient lighting. Physical controls are expected to return in key areas for better usability, addressing feedback on the previous generation’s capacitive interfaces.
AMG-specific touches such as performance seats, unique steering-wheel controls, and a more aggressive exhaust note selector should distinguish the S63 from its milder siblings.
Pricing and US Market Availability
Exact pricing has not been announced. The current (2026) Mercedes-AMG S63 E Performance starts at approximately $189,800. Given the extensive updates and inflationary pressures, the 2027 model is expected to command a similar or slightly higher starting price, likely in the $190,000–$210,000 range before options.
U.S. availability will follow the official global debut. Interested buyers should contact Mercedes-Benz dealers for the latest allocation information once the model is confirmed for the American market. Inventory is typically limited in the first model year for high-performance flagships of this caliber.
What U.S. Buyers Should Watch For Next?
Mercedes-AMG is expected to reveal the 2027 S63 before the end of 2026 to complete the refreshed S-Class range. Until then, the most reliable information continues to come from spy photography and technical details already confirmed on related models using the new flat-plane V8.
For American shoppers seeking the ultimate blend of S-Class luxury and AMG performance, the waiting period appears relatively short. Official specifications, pricing, and dealer arrival windows should become clear once Mercedes schedules the formal premiere.
