Mercedes-AMG Unveils Its First In-House Electric SUV
By Drooid · · How we work
Core Event
Mercedes-AMG announced the 2028 Mercedes-AMG GT SUV, the brand’s first full-size sport-utility vehicle developed entirely in-house on the AMG.EA 800-volt architecture. The model will launch in U.S. dealerships in the summer of 2027 and will be offered in three trims—GT 53, GT 55 and GT 63—each with an all-electric powertrain.
Background & Context
The GT SUV builds on the technology introduced with the AMG GT 4-Door Coupe earlier this year, marking AMG’s shift from high-performance sedans to a dedicated SUV platform. The vehicle is assembled at the historic Sindelfingen plant after development at AMG’s Affalterbach headquarters.
Data & Statistics
| Trim | Motor Layout | Peak Power | Continuous Power | Torque (lb-ft) | 0-60 mph* | Top Speed* | Battery (kWh) | Fast-Charging Max |
|---|---|---|---|---|---|---|---|---|
| GT 53 | Dual-motor (front & rear) | 536 hp | 362 hp | 590 | 4.1 s (Car & Driver) | 143 mph | 106 kWh | 600 kW |
| GT 55 | Tri-motor (1 front + 2 rear) | 805 hp | 711 hp | 1 372 | 3.0 s (Car & Driver) | 168 mph | 128 kWh | 710 kW |
| GT 63 | Tri-motor (1 front + 2 rear) | 1 153 hp | 711 hp | 1 475 | 2.4 s | 168 mph (electronically limited) | 128 kWh | 710 kW |
*Performance figures are manufacturer-claimed; independent testing varies.
Weight ranges from 5 567 lb (GT 53) to 5 941 lb (GT 63). Cargo capacity is 21 cu ft behind the rear seats, expanding to 61 cu ft with seats folded. The larger battery packs enable WLTP-rated ranges of 435 mi (GT 63) to 500 mi (some sources) and can add 280 mi in 10 minutes at 710 kW.
Official Statements & Responses
- Technical Claims – Mercedes-AMG states that the 800-volt battery uses directly cooled cylindrical cells derived from Formula 1 technology, enabling up to 710 kW DC fast charging and sustained 711 hp output for up to 63 seconds.
On-the-Ground Reports
Motor1’s ride-along at Monterey Car Week observed that the prototype felt “quick,” with a dyno-estimated 0-60 mph time near 2.5 seconds, comparable to the GT 4-Door Coupe. The journalist reported a displayed WLTP-rated range of roughly 300 mi on a 96 % charge and noted that the suspension and damping had been tuned to accommodate the heavier SUV body while retaining AMG’s handling feel. The test also confirmed simulated engine noises and seat-vibration feedback in AMGForce Sport+ mode.
Conflicting Reports & Gaps
- Peak Power – Most sources list the GT 63’s peak output as 1 153 hp, but Pistonheads reports 1 169 hp.
- Range Estimates – WLTP-based range figures vary: Roadandtrack cites a maximum of 435 mi, Car & Driver mentions 277–370 mi (EPA-style estimates pending), while CarBuzz projects up to 500 mi depending on driving conditions.
- Charging Times – All sources agree on 710 kW charging for the 128 kWh pack, but the exact added mileage (280 mi vs 450 km) is expressed in both miles and kilometres, creating minor conversion discrepancies.
- Pricing – No official U.S. pricing has been released; European entry-level pricing is quoted at €113 050, while Motor1 expects a high-$90 000 starting point in the United States.
