MERCEDES-BENZ GT 63 S
The Mercedes-Benz GT 63 S is a high-performance four-door coupe available in body styles that blend luxury with sporty character. It is powered primarily by a twin-turbocharged 4.0-liter V8 engine. Depending on the exact variant, output ranges from approximately 577 horsepower up to 630 horsepower in the GT 63 S, with some enhanced models delivering combined power exceeding 800 horsepower when paired with electric motors. Transmission duties are handled by a 9-speed automatic or a dual-clutch system, and the vehicle employs an all-wheel-drive layout, enhancing traction and handling. Fuel economy varies widely, with real-world figures around 12 to 19 miles per gallon in gasoline-only operation, while plug-in hybrid variants can achieve around 45 MPGe. Inside, the GT 63 S offers a refined interior space with seating for four and a modest trunk volume near 19 cubic feet behind the rear seats, emphasizing style and sporty ergonomics. Key safety features include advanced driver assistance systems such as adaptive cruise control, blind-spot monitoring, and active emergency braking.
Regarding its strengths, the Mercedes-Benz GT 63 S is renowned for blistering acceleration, with sprint times to 60 mph in the low 2-second range for the hybrid versions and top speeds near 200 mph. Its richly equipped cabin and cutting-edge technology packages contribute to a luxurious experience. However, the vehicle’s resale value may depreciate relatively quickly compared to more mainstream luxury sedans, and maintenance costs tend to be high, consistent with flagship AMG models. Some owners report complexity in electronics and high costs associated with repairs and upkeep. Reliability is generally good but comes with the caveat of expensive servicing. Its fuel economy is notably poor compared to conventional sedans, which is a trade-off for its exceptional performance.
Key specs and highlights
The heart of the Mercedes-AMG GT 63 S is a 4.0-liter twin-turbocharged V8 engine producing 603 horsepower and 627 lb-ft of torque in the latest performance versions. Hybrid variants add an electric motor for a combined system output exceeding 800 horsepower and over 1000 lb-ft of torque. A 9-speed automatic transmission delivers power to all four wheels via an AMG Performance 4MATIC+ all-wheel-drive system. Braking uses high-performance composite discs with multi-piston calipers for strong stopping power.
Measuring approximately 186 inches in length with a 106-inch wheelbase, the GT 63 S features a spacious interior accommodating four passengers comfortably. Cargo capacity is about 19 cubic feet behind the rear seats, suitable for daily use but less than large sedans. Noteworthy technology includes the advanced MBUX infotainment system with touchscreen and voice control, driver assistance suites with active safety functions, and optional aerodynamic enhancements that improve high-speed stability.
Driving experience
Driving the AMG GT 63 S is a visceral experience defined by intense acceleration and razor-sharp handling. The V8’s immediate throttle response and the hybrid system’s instant torque provide explosive launch performance. Handling is balanced, aided by dynamic all-wheel drive and adaptive air suspension that firm up the ride for aggressive cornering but soften for cruising.
Ride comfort remains surprisingly good for a high-performance sedan, though it leans toward firm over bumps. Interior noise is well controlled, but the engine’s growl is a signature element cherished by enthusiasts. Seats provide excellent support during spirited driving and hold occupants firmly in place.
Visibility is decent but can feel restricted due to its coupe-like silhouette and wide pillar structure. Daily usability is aided by modern parking sensors and cameras yet requires attentiveness in tight spaces given its wide stance.
Trims and equipment
The AMG GT 63 S is offered mainly as a performance flagship within the AMG GT four-door lineup. Key trims include the standard GT 63, the GT 63 S with enhanced power, and electrified ‘E Performance’ versions adding hybrid assistance. Options encompass forged 21-inch wheels, advanced aerodynamic packages with front splitters and rear spoilers, and interior upgrades like exclusive Nappa leather and carbon-fiber trim.
Notable packages improve comfort and technology, including the Driver Assistance package, which brings adaptive cruise control, emergency evasive steering assist, and lane-keeping aids. Acoustic Comfort packages add additional sound insulation for a quieter cabin. Given the vehicle’s performance focus, summer performance tires are recommended options to maximize grip.
Reliability and maintenance
The AMG GT 63 S generally shows good reliability for a complex high-performance car but requires diligent upkeep. Reported issues often relate to electronic components and occasional software glitches. Routine maintenance follows a strict schedule, with premium synthetic oil changes recommended every 10,000 miles and inspections of the forced induction system.
Owners should budget for high annual maintenance costs, including expensive brake replacements and tire wear due to aggressive power delivery. Warranty coverage for new vehicles is typical of luxury brands, but repairs outside warranty are costly. Potential buyers should seek well-documented service histories and avoid cars with neglected maintenance.
Fuel economy and running costs
Fuel consumption is a significant consideration with the GT 63 S; gasoline-only models average 12 to 19 mpg combined, while the latest plug-in hybrid E Performance version improves to roughly 45 MPGe on electric and gas combined, albeit with a limited pure electric range near 7 miles.
Running costs extend beyond fuel, including high insurance premiums due to the car’s performance classification and strong depreciation. Tires and brakes experience accelerated wear, meaning replacement expenses frequently surpass those of non-performance sedans. Maintenance and repairs remain significantly more expensive than average vehicles, reflecting the AMG’s specialized engineering.
Safety and driver assistance
The Mercedes-AMG GT 63 S comes loaded with an extensive suite of safety features. Standard items include multiple airbags, electronic stability control, and a reinforced body structure designed to offer superior crash protection.
Advanced driver assistance systems (ADAS) feature adaptive cruise control with stop-and-go functionality, blind-spot monitoring, lane departure warnings, and collision avoidance systems with autonomous emergency braking. Traffic sign recognition and evasive steering assistance further enhance safety during everyday and high-speed driving.
Model history and changes
The AMG GT 63 S debuted as a more practical and spacious companion to the two-door AMG GT coupe, expanding AMG’s lineup into four-door luxury performance. Over successive years, power and technology upgrades have been introduced, including the addition of hybrid-assisted versions branded as E Performance, which significantly boost power and torque.
Recent model years emphasize electronic refinement, aerodynamic efficiency, and interior luxury enhancements. Buyers today favor the latest models with hybrid technology for their superior performance and evolving efficiency, though traditional V8-only versions retain appeal for purists.
Competitors and alternatives
Competitors to the Mercedes-AMG GT 63 S include the Porsche Panamera Turbo, Audi RS7, and BMW M8 Gran Coupe. Compared to these, the AMG GT 63 S offers a more dramatic powertrain combination with hybrid boosts on recent models, superior straight-line acceleration, and a uniquely aggressive exhaust note.
While the Porsche emphasizes sharp handling and refinement, and the Audi provides tech-laden luxury with practicality, the AMG GT 63 S stands apart with its muscular V8 character and bespoke AMG tuning, although it comes with higher running costs.
Buying advice and verdict
The Mercedes-Benz GT 63 S is best suited for buyers seeking a blend of extreme performance and four-door practicality wrapped in an exclusive luxury package. Enthusiasts wanting a head-turning car with cutting-edge performance tech will find the AMG GT 63 S compelling.
Pros include blistering acceleration, sumptuous interior materials, and an advanced suite of driving aids. Cons involve steep maintenance expenses and limited fuel economy. Prospective buyers should prioritize models with full service records and consider the hybrid versions for added power and efficiency.
Overall, the GT 63 S commands respect as a top-tier performance sedan with a unique character that few rivals match, making it a desirable choice within its exclusive market segment.
