This is good enough to slingshot the near-6,000-pound sedan to 60 mph in just 3.0 seconds, ably assisted by a 9-speed automatic transmission, rear-wheel steering, and AMG Performance 4Matic AWD.AdvertisementAdvertisementYet, the standard AMG Ride Control air suspension also ensures the kind of ride comfort expected of an S-Class, enabling this AMG to rub shoulders with exalted company like the sumptuous Bentley Flying Spur and sporty Porsche Panamera Turbo S E-Hybrid.MercedesView the 1 images of this gallery on the original articleWhat's New for 2025The 2025 AMG S 63 E Performance gets a 3-year SiriusXM Extended Subscription and smartphone-based digital key capability as standard convenience features, while safety is shored up by the addition of a front center airbag. Dolby Atmos integration is added to the Burmester 3D surround-sound audio system.More options come on stream this year, including carbon-ceramic composite brakes with 16.5 x 1.6-inch discs and bronze 6-piston callipers, as well as the option to increase the top speed to 180 mph. Two metallic paint options join the palette: Verde Silver and Sonoran Brown. The only other change is that the Executive Line trim is renamed Pinnacle.AdvertisementAdvertisementThe 2026 Mercedes-AMG S 63 E Performance’s price is $186,200.ExteriorThe S 63 E Performance follows the template of the standard S-Class and has its familiar profile, but with some restrained AMG intent added, starting with bigger front air intakes, a wider grille, and 20-inch AMG wheels. Quad exhausts finish off the shape while maintaining the expected executive decorum. The long, graceful silhouette conveys power through its proportions instead of aggressive add-ons, and there’s an extensive color palette and several exclusive Manufaktur colors.MercedesView the 3 images of this gallery on the original articleInteriorThe cabin is peak S-Class, with AMG-specific animations for the 12.3-inch 3D gauge cluster. The 12.8-inch portrait MBUX center touchscreen incorporates biometric authentication, navigation, over-the-air updates, wireless Apple CarPlay and Android Auto, a wireless charging pad, and 710-W, 15-speaker Burmester 3D surround-sound system with Dolby Atmos.AdvertisementAdvertisementStandard kit includes illuminated sill plates, Nappa leather upholstery, heated and ventilated front and rear seats, massaging 12-way power front seats, 64-color adjustable ambient lighting, power outboard rear seats, heated armrests, and soft-close doors.MercedesView the 3 images of this gallery on the original articlePrice Range and Best Value TrimTrimPrice (MSRP, excl. destination)Base: AMG S 63 E Performance$186,200Top (as configured): AMG S 63 E Performancevaries with optionsBest Value: AMG S 63 E Performance$186,200The S 63 E Performance is sold in a single trim and it’s extensively equipped from the factory.

It’s unique among full-size luxury sports sedans, since none of its price rivals offer close to 800 hp and this level of performance, though the more expensive Bentley Flying Spur is also a PHEV nowadays. The F1-derived PHEV architecture convincingly proves that AMG performance and electrification can coexist. Even carbon-ceramic brakes are available this year for the serious driver.AdvertisementAdvertisementThe minuses are perhaps not unexpected, including a curb weight of nearly 6,000 pounds, which means that even the trick suspension struggles to hide the car’s weight, as well as the rather low 16-mile electric range and the small 10.7-cu-ft trunk. It’s also sobering that no complimentary maintenance is included at $186K, at a time when even Audi offers this benefit now. Accept these terms and the S 63 E Performance is still one of the most comfortable ways to go embarrassingly fast.MercedesView the 1 images of this gallery on the original articleCompetitorsAudi RS7Audi S8BMW 760i xDrivePorsche Panamera Turbo S E-HybridBentley Flying SpurShop the Car MarketplaceView the original article to see embedded media.AdvertisementAdvertisementThis story was originally published by Autoblog on May 29, 2026, where it first appeared in the Cars section.
