2026 Mercedes-AMG GT 4-Door Coupé (C590): 1,169 hp Tri-Axial-Flux EV Kills The V8 4-Door

Mercedes-AMG just made the most significant announcement of its 58-year history. On May 19, 2026 in Affalterbach, AMG world-premiered the all-new second-generation GT 4-Door Coupé (internal code C590) — and it’s a clean-sheet, fully-electric replacement for the outgoing V8/I6 X290 lineup. The new GT 4-Door is the first production passenger car globally to use three axial-flux motors (one front + two rear, supplied by AMG’s in-house Yasa subsidiary in the UK), spins those rear motors past 15,000 rpm, hits 1,169 hp combined on the GT 63 top trim with 2,000 Nm of torque, and accelerates from 0-100 km/h in just 2.1 seconds. The 800-volt 106 kWh battery uses 2,660 cylindrical NCMA cells with F1-derived direct oil cooling, supporting 600 kW peak DC charging — 460 km of WLTP range added in 10 minutes. The headline reveal: Mercedes-AMG has killed the V8 GT 4-Door entirely. No more M177, no more I6 mild-hybrid, no more E PERFORMANCE PHEV. The decathlete of sports cars is now a fully-electric tri-motor sports sedan built in Sindelfingen, ready for series production summer 2026 with US deliveries scheduled for late 2026.

Performance & Specs

The 2026 GT 4-Door Coupé launches in two trims: GT 55 4MATIC+ and GT 63 4MATIC+. Both use the same three-motor architecture, with the GT 63 unlocking higher peak output via different software calibration and continuous-output thermal management. The GT 55 delivers 805 hp (600 kW) peak in Launch Control mode with 1,800 Nm (1,328 lb-ft) of torque and 503 hp continuous, hitting 100 km/h in 2.8 seconds with a 300 km/h top speed (with optional AMG Driver’s Package). The GT 63 elevates everything: 1,169 hp (860 kW) peak, 2,000 Nm (1,475 lb-ft) of torque, 711 hp continuous output, 0-100 km/h in 2.1 seconds, 0-200 km/h in 6.4 seconds, and the same 300 km/h top speed. Both share the new AMG.EA platform with fully-variable Performance 4MATIC+ AWD — rear-biased with independent motor torque vectoring across all three units. Single-speed direct-drive replaces the outgoing 9-speed MCT dual-clutch transmission.

Dimensions & Practicality

Length	5,094 mm
Width	1,959 mm
Height	1,411 mm
Wheelbase	3,040 mm
Drag coefficient	0.22 Cd

The new GT 4-Door grows meaningfully versus the outgoing X290 generation: 5,094 mm long (vs 5,054 mm), 3,040 mm wheelbase (+89 mm), and a lower 1,411 mm roofline. The 0.22 drag coefficient is achieved via active aerokinetics — the rear spoiler deploys above 80 km/h, the Venturi flow underbody panels activate at 120 km/h, vertical front louvers balance cooling against aerodynamic efficiency, and an active rear diffuser extends to optimize high-speed downforce. The cabin uses a strict 2+2 four-seat layout (no rear bench option), with the sky-controlled panoramic roof embedding an illuminated AMG crest. The front trunk delivers approximately 60 liters (2.1 cu ft) of storage — modest but useful for charging cables. Liftback rear hatch layout retains the GT 4-Door’s practicality versus a traditional 4-door sedan; exact rear cargo volume has not yet been officially disclosed. Curb weight is 2,460 kg (~5,423 lb) — substantial but proportional to the 1,169 hp performance.

Charging & Battery

The new GT 4-Door’s 106 kWh battery is the most technically ambitious EV battery Mercedes-AMG has ever produced. It uses 2,660 cylindrical NCMA cells with silicon-containing anodes, with each cell directly oil-cooled via an F1-derived cooling architecture that AMG proved at the Nürburgring during the record-drive validation. The 800-volt architecture supports 600 kW peak DC charging on compatible high-power stations — completing a 10-80% top-up in approximately 11 minutes, or adding 460 km of WLTP range in just 10 minutes. WLTP range is 597-700 km on the GT 55 and 596-696 km on the GT 63, depending on wheel choice (21-inch aero wheels recover roughly 8.7 miles of range vs standard 21-inch styled wheels). The car supports CCS2 (Europe), CCS1 (North America), NACS (Tesla connector), CHAdeMO (legacy Japan), and GB/T (China) charging standards out of the factory — truly global charging compatibility built in. AC charging on the standard 11 kW onboard charger replenishes the pack overnight in approximately 11 hours.

Design & Interior

The new GT 4-Door Coupé’s exterior is the cleanest evolution of AMG’s design language since the original 2018 X290 launch. The front fascia centers on an illuminated “Panamericana”-style grille with vertical bars and an integrated AMG-branded center crest. The hood retains the AMG signature power domes, while the lower fascia features vertical aerokinetic louvers that automatically open and close to balance cooling needs versus aerodynamic drag. The greenhouse is low and wide with frameless side glass, and the roofline slopes dramatically into the liftback rear. At the back, the signature six turbine-style LED tail lights arranged in a triangular cluster (three each side) form the visual centerpiece, framed by a black panel and the active rear diffuser. The launch yellow color in the video walkaround is “MANUFAKTUR alpine green”-adjacent and uniquely identifies the C590. Inside, AMG continues its driver-focused performance cabin philosophy: heavily bolstered front bucket seats with diamond-stitch quilted leather and AMG monogram, three signature center-console rotary controllers (Response / Agility / Traction), the new MB.OS infotainment running on a 14-inch central touchscreen, 10.2-inch driver instrument cluster, and an optional 14-inch front passenger display. The dashboard’s vertical AMG-branded ambient lighting strip reacts to drive mode selection. The reviewer (Chief Engineer Oliver Wiech) specifically demonstrates the sky-controlled panoramic roof with embedded AMG crest light show that activates on door-open or vehicle-startup.

Technology & Features

The GT 4-Door Coupé is the first vehicle globally to deploy Mercedes’ new MB.OS operating system — a complete in-house redesign of the company’s infotainment stack. MB.OS integrates ChatGPT, Microsoft Bing, and Google Gemini as separate AI assistants the driver can switch between via voice command, with each handling different conversational use cases. The central 14-inch touchscreen pairs with a 10.2-inch driver instrument cluster and an optional 14-inch front passenger display. AMG-specific software layers add the “AMG Race Engineer” interface for the three center-console rotary dials, real-time track telemetry, drift angle / G-force / lap-time displays, and the Force S+ V8 sound module that synthesizes acceleration audio from over 1,600 sampled GT R V8 sound files — with the option to drive in total silence if the driver prefers. Wireless smartphone integration covers Apple CarPlay, Android Auto, and Mercedes Me app pairing. The sky-controlled roof can activate a crest-light animation synchronized with vehicle startup, and a 360-degree surround camera + augmented-reality navigation overlay round out the visualization features.

Safety & ADAS

ADAS LEVEL	L2 (Mercedes Driver Assistance Package standard)
LiDAR	Not standard (Drive Pilot L3 certification TBA for C590)
RADARS	Multiple short + long-range radar units (count TBA)
CAMERAS	Multiple HD + 360-degree surround
ADAS FEATURES	Active Distance Assist, Active Lane Keeping, Active Brake Assist, Blind Spot Assist, 360° camera, Parking Assist

The GT 4-Door Coupé ships with Mercedes’ standard Driver Assistance Package providing Level 2 highway assist (Active Distance Assist + Active Lane Keeping), Active Brake Assist with vehicle/pedestrian/cyclist detection, Blind Spot Assist with rear cross-traffic alert, and 360-degree surround camera with parking automation. Drive Pilot Level 3 (Mercedes’ geofenced hands-off autonomous system, currently available on EQS / S-Class in California and Nevada) certification on the C590 has not yet been confirmed by Mercedes — expect this announcement during the 2027 model year refresh cycle once the new MB.OS platform receives appropriate regulatory certification.

Pricing & Availability

Mercedes-AMG has not yet officially disclosed MSRP for the C590 GT 4-Door Coupé. Press estimates put the GT 55 4MATIC+ in the $110,000-$130,000 range based on the outgoing X290 GT 53 pricing structure, with the GT 63 4MATIC+ expected to challenge the $200,000-$240,000 territory (Porsche Taycan Turbo GT is $243,700, providing the most relevant benchmark). The model is assembled at the Mercedes-Benz Sindelfingen plant in Germany — not the traditional Affalterbach hand-build facility — reflecting the move to mainstream-EV production volumes rather than ultra-low-volume specialist craftsmanship. Series production begins summer 2026, with European customer deliveries starting Q3 2026 and US deliveries scheduled for late 2026. Order books open at AMG dealerships globally with deposits accepted now. The outgoing X290 V8/I6 GT 4-Door lineup ends production in 2026 — no overlap year.

How It Compares

The 2026 AMG GT 63 4-Door now competes directly with the Porsche Taycan Turbo GT (the segment’s previous benchmark) and the Lucid Air Sapphire — with the Xiaomi SU7 Ultra as the emerging Chinese threat. On peak power, Xiaomi SU7 Ultra wins (1,548 hp vs 1,169 hp), Lucid Air Sapphire is next (1,234 hp), then AMG GT 63 ahead of the Porsche Taycan Turbo GT (1,019 hp). On 0-100 acceleration the order shifts slightly: Lucid Air Sapphire (1.9s) → Xiaomi SU7 Ultra (1.97s) → AMG GT 63 (2.1s) → Porsche Taycan Turbo GT (2.2s) — all within 0.3 seconds, which means real-world differences come down to launch surface and tire grip. On range, AMG’s 700 km WLTP edges Lucid’s 687 km and beats Porsche’s 555 km comfortably. The AMG’s most differentiated feature versus all three rivals is the axial-flux motor architecture — nobody else uses them in production EVs yet, and Mercedes claims (via Yasa research) significantly higher power density and lower mass than traditional radial-flux motors.
