Overview of the 2028 Mercedes‑AMG GT SUV
Mercedes‑AMG is set to rewrite the performance‑SUV playbook with the 2028 GT SUV, its inaugural full‑size electric SUV built entirely in‑house. The vehicle combines a staggering 1,150 horsepower output with ultra‑fast‑charging capability, promising sports‑car dynamics in a body that can comfortably seat a family. Built on the brand‑new AMG.EA architecture, the GT SUV is scheduled to arrive in the United States next summer, positioning AMG as a serious contender in the high‑performance EV segment.
Key highlights:
- Powertrain – 1,150 hp electric drivetrain delivering instantaneous torque.
- Charging – Proprietary ultra‑fast‑charging system targeting 80 % charge in under 20 minutes.
- Architecture – First AMG model on the dedicated AMG.EA platform, engineered for both agility and SUV practicality.
- Production – Fully in‑house development from chassis to battery pack, marking a strategic shift away from platform sharing.
Technical Breakdown
AMG.EA Architecture
The AMG.EA (Electric Architecture) is a modular, skateboard‑style platform that places the battery pack flat under the floor, lowering the centre of gravity and freeing up interior volume. Unlike previous AMG models that adapted existing Mercedes‑Benz platforms, AMG.EA is designed from the ground up for high‑performance electric applications.
- Battery Capacity – Estimated at 120 kWh, optimized for both range and power delivery.
- Motor Layout – Dual‑motor setup with a front and rear unit, each capable of 575 hp, enabling sophisticated torque vectoring.
- Thermal Management – Integrated liquid‑cooling loops for both battery and motors, ensuring consistent performance under track‑day conditions.
Ultra‑Fast‑Charging System
Mercedes‑AMG has partnered with a leading charging network to develop a proprietary 350 kW DC fast‑charging protocol. The system uses a high‑current, low‑voltage architecture to reduce heat generation, allowing the GT SUV to replenish 80 % of its battery in roughly 18 minutes under ideal conditions.
- Charging Curve – Linear power delivery up to 300 kW, tapering to protect battery health.
- Onboard Charger – 22 kW AC capability for home charging, supporting both Type‑2 and CCS connectors.
- Smart Integration – Vehicle‑to‑grid (V2G) functionality that can feed excess energy back to the grid during peak demand.
Performance Figures
While official acceleration numbers have not been released, extrapolations based on power and weight suggest a 0‑60 mph time in the low 2‑second range, rivaling the internal‑combustion GT R. The SUV’s aerodynamic package, featuring active grille shutters and a rear diffuser, helps maintain a drag coefficient near 0.30 despite its size.
Why It Matters
Redefining the Performance SUV Segment
The GT SUV arrives
the market at a time when luxury performance EVs are still a niche, and it does so with a blend of raw power and everyday usability that few rivals can match. By delivering over a megawatt of output in a full‑size SUV, AMG is challenging the notion that high‑performance electric cars must be low‑slung sports cars. The GT SUV also signals Mercedes‑AMG’s commitment to an all‑electric future, showing that the brand can retain its performance DNA while embracing new powertrain technology.
Design & Aerodynamics
The exterior styling stays true to AMG’s aggressive GT lineage, featuring a wide‑track stance, a sculpted front fascia with a large active grille, and a rear spoiler that deploys automatically at higher speeds. The vehicle’s underbody is fully covered, and active aerodynamic elements—including an adjustable rear diffuser and front splitter—work together to keep drag low while generating downforce when needed. Despite its size, the SUV maintains a drag coefficient of approximately 0.30, a figure more typical of sleek coupes than traditional boxy SUVs.
Inside, the cabin merges luxury with a driver‑focused cockpit. A 15‑inch OLED central display runs the infotainment suite, while a secondary 12‑inch digital instrument cluster provides real‑time performance data, including torque vectoring maps and battery health. Premium Nappa leather, carbon‑fiber trim, and a configurable ambient lighting system create a high‑end ambience. Seating for five is complemented by a configurable rear bench that can fold flat to expand cargo capacity up to 1,800 L, making the GT SUV practical for both weekend getaways and daily errands.
Sustainability & Technology
Beyond performance, AMG is emphasizing sustainability throughout the vehicle’s lifecycle. The battery pack incorporates a high proportion of recycled lithium‑ion cells, and the manufacturing process at the Mercedes‑Benz plant in Sindelfingen utilizes renewable energy sources for over 70 % of its electricity consumption. The GT SUV also supports over‑the‑air (OTA) updates, allowing the powertrain software to evolve post‑delivery, improving efficiency and unlocking new driving modes.
A standout feature is the integrated Vehicle‑to‑Grid (V2G) capability. When parked at home or at a compatible public charger, the SUV can discharge up to 20 kW back into the grid, providing owners with a potential revenue stream or a backup power source during outages. This bidirectional charging aligns with broader industry moves toward grid‑interactive EVs.
