2028 Mercedes-AMG GT SUV: Up to 1,153 HP, Three Versions and a Summer 2027 Launch
Table of Contents
The 2028 Mercedes-AMG GT SUV is an electric performance SUV that goes on sale next summer. The top GT63 makes up to 1,153 horsepower and is claimed to reach 60 mph in 2.4 seconds. Pricing and official range figures have not been announced.
It is the first SUV developed in-house by AMG and the second vehicle on AMG’s AMG.EA high performance electric architecture, after the 2027 AMG GT 4-door sedan.
Three versions: GT63, GT55 and GT53
The lineup has three models. The GT63 and GT55 share a three motor layout, while the GT53 is a simpler, lighter and likely cheaper version unique to the SUV.
| Specification | GT63 SUV | GT55 SUV | GT53 SUV |
|---|---|---|---|
| Motors | Three axial flux | Three axial flux | Two radial flux permanent magnet |
| Peak horsepower | 1,153 | 805 | 536 |
| Sustained horsepower | 711 | 711 | Not stated |
| Torque | 1,475 lb-ft | 1,372 lb-ft | 590 lb-ft |
| 0 to 60 mph | 2.4 sec (claimed) | Not stated | Not stated |
| Battery (usable) | 128 kWh | 128 kWh | Smaller 18 module pack, same as the sedan |
The GT63 SUV has the same powertrain output as the GT63 sedan. The sedan is rated at 2.0 seconds to 60 mph, so the SUV is slower off the line. The extra weight and larger frontal area explain the gap.
How the powertrains work
The GT55 and GT63 use axial flux motors. Two sit at the rear for propulsion and torque vectoring, and one at the front adds thrust when needed. Axial flux motors have been hard to build at scale. They have mostly appeared on the electric front axles of exotic sports cars such as the Ferrari 296 GTB and the Lamborghini Revuelto and Temerario.
The GT53 takes a more conventional route. It has two radial flux permanent magnet motors. The front motor is direct drive, and the rear motor works with a two speed automatic transmission. It weighs almost 400 pounds less than the other two models.
Battery and range
The GT55 and GT63 use an 800 volt battery with 22 modules and 128 kWh of usable capacity. The sedan has 18 modules and 106 kWh, so the SUV pack is 22 percent larger. The SUV is also about 520 pounds heavier than the sedan.
Mercedes has not released range or consumption figures, and none are expected until closer to launch. Car and Driver has offered its own estimates, which should be treated as analysis rather than confirmed data:
- The bigger battery roughly offsets the SUV’s weight and drag, leaving a range only about 2 percent better than the sedan.
- The GT53 may trail the three motor SUVs by around 4 percent, because its motors are more efficient. That estimate comes from the European WLTP figures provided.
- The GT53 could match or slightly trail the GT63 sedan, which Car and Driver previously estimated at about 300 miles.
WLTP is a European test cycle, and EPA ratings for the US will differ.
Suspension, interior and sound
The SUV gets a new AMG Active Ride Control Plus suspension with active roll and pitch stabilization. It builds on the cross linked damper system in the GT63 sedan. For the SUV, the front and rear axles are also interconnected to control squat under acceleration and dive under braking. Three chamber air springs return, though Car and Driver expects them to be retuned.
Inside, the layout is close to the sedan’s. The screen angles toward the driver, and the three knob AMG Race Engineer controls response, agility and traction. Rear seat space is much better than in the sedan. Car and Driver’s technical editor, who is 6 feet 2 inches tall, said he could sit behind his own driving position with plenty of headroom and comfortable foot space.
The AMGFORCE Sport Plus mode adds simulated gear changes, a lumpy idle and seat vibration. The GT55 and GT63 simulate a V8 sound, and the GT53 simulates a six cylinder. The sound is played both inside and outside the car, and the driver can switch it off. Car and Driver has not yet driven the SUV and said it remains unconvinced by the sound.
Price and availability
The SUV goes on sale next summer, which points to the 2027 summer season. Official pricing has not been announced, and the sources do not specify which markets will get the SUV.
Car and Driver reports that the GT55 and GT63 will cost more than their sedan counterparts. It expects the GT53 to start below the GT55 sedan, at around $130,000 give or take. That figure is an estimate, not a Mercedes price.
What it means for buyers
The GT53 is the model to watch for buyers who want the AMG badge and a roomy electric SUV without paying for the top powertrain. It gives up a lot of power but is lighter, and its range may not suffer much. The GT55 and GT63 suit buyers who want maximum performance and the larger battery.
Real world range, final pricing and driving impressions will decide how the SUV compares with the sedan and with rivals.
Motor Yaan verdict
The AMG GT SUV adds space and a cheaper entry point to a very powerful electric platform. Its biggest strength is the spread of options, from 536 hp to 1,153 hp. Its biggest weakness is the unknowns: official range, pricing and how the simulated sound and active suspension feel on the road. Buyers should wait for those details before committing.

2028 Mercedes-AMG GT SUV FAQs
Quick answers on power, models, range, price and launch timing.
How powerful and how fast is the 2028 Mercedes-AMG GT63 SUV?
The GT63 SUV makes up to 1,153 peak horsepower, 711 sustained horsepower and 1,475 pound feet of torque from a three motor setup. That is the same output as the GT63 sedan. The claimed 0 to 60 mph time is 2.4 seconds, compared with 2.0 seconds for the sedan. The extra weight and larger frontal area explain the gap.
What is the difference between the GT63, GT55 and GT53 SUV?
The GT63 and GT55 both use three axial flux motors and a 128 kWh battery. The GT55 makes 805 peak horsepower and 1,372 pound feet of torque. The GT53 is unique to the SUV and uses two radial flux permanent magnet motors for 536 peak horsepower and 590 pound feet of torque. It also weighs almost 400 pounds less than the other two.
How big is the battery and what is the range?
The GT55 and GT63 have an 800 volt battery with 128 kWh of usable capacity, up from 106 kWh in the GT sedan. The GT53 uses the sedan's smaller 18 module pack. Mercedes has not released range figures yet. Car and Driver estimates the GT63 SUV may match or slightly beat the GT63 sedan's estimated 300 miles, and the GT53 may trail the three motor models by only about 4 percent. These are estimates, not official ratings.
How much will the AMG GT SUV cost?
Official pricing has not been announced. Car and Driver reports that the GT55 and GT63 will cost more than their sedan counterparts. It expects the GT53 to start below the GT55 sedan, at around $130,000, give or take. That figure is an estimate and not a Mercedes price.
When does the 2028 Mercedes-AMG GT SUV go on sale?
It goes on sale next summer, according to Car and Driver. Market by market availability has not been detailed, so US buyers should confirm timing with Mercedes-Benz USA.
Does the AMG GT SUV sound like a real V8?
No, the sound is simulated. The GT55 and GT63 mimic a V8, and the GT53 mimics a six cylinder. AMGFORCE Sport Plus mode also adds simulated gear changes, a lumpy idle and seat vibration. The sound plays inside and outside the car, and the driver can switch it off.
