Mercedes-AMG's electric GT SUV launches with 1,153 hp and GT63, GT55, GT53 trims

Mercedes-AMG has unveiled an SUV version of the GT 4-Door, its first electric-only model, and the range-topping GT63 develops up to 1,153 hp. The high-riding EV carries the super sedan's performance hardware onto the same AMG.EA platform while adding more interior space and cargo room.

Three versions will be sold. The tri-motor GT63 is the flagship, making a combined 1,153 hp, of which 711 hp is continuous output, with 1,475 ft lbs of torque. That is enough for zero to 60 mph in 2.8 seconds and a top speed of 168 mph.

Below it is the tri-motor GT55 with a maximum 805 hp and 1,372 ft lbs of torque, and the dual-motor GT53 with up to 536 hp and 590 ft lbs. The axial motors used across the line are the kind normally confined to supercars rather than family-sized EVs.

Battery, range and handling

The GT63 runs an 800-volt electrical system and carries a 128 kWh battery pack. Mercedes estimates a range between 385 and 435 miles on a charge, though that figure comes from the WLTP cycle, so the EPA number for the U.S. will land lower.

Range anxiety is not meant to be a concern, but the more interesting concession is that the company has not priced the SUV yet. Reporting points toward a start below the $130,000 opening price of the range-topping AMG GT55 4-Door sedan.

Handling is tuned to belie the SUV body. The AMG Active Ride Control+ suspension is standard on the GT63, which also carries the AMG Dynamic Plus package, and is offered as an option on the GT55. Every trim produces a simulated engine note through the cabin.

The GT63 and GT55 are voiced like a V-8, while the GT53 sounds like a V-6. It is a reminder that this is AMG's performance wing stretching into electrification, and the acoustic trick is aimed squarely at buyers who still want a combustion soundtrack.

Design and the cabin

The styling takes the GT 4-Door and enlarges it to SUV proportions, and the result suits the bigger canvas. A wide stance, prominent wheel arches and a sharp roofline mark it out, and the marque's performance sub-brand expects it to read as one of the most athletic SUVs on sale.

Inside, the front row is nearly identical to the sedan's, with a 10.2-inch digital gauge, a 14-inch infotainment touchscreen and an optional 14-inch passenger display. Where the two bodies diverge is the rear: the SUV's three-person second row offers significantly more room.

Cargo space behind the seats measures 21.4 cubic feet, and folding the second row opens it to around 61 cubic feet. A trunk compartment adds a further 2.4 cubic feet. The cabin can be personalized through the automaker's Manufaktur program, as on the sedan.

This is the same formula the brand applied to its combustion GLS, and it reads as a deliberate answer to a market that keeps choosing SUVs over fast sedans.

What we reported when the GT SUV first broke was that it is Mercedes-AMG's first in-house SUV. That detail matters here: the electric GT line was already the sub-brand's first EV, and now the SUV body carries both firsts at once, built on an architecture AMG developed itself.

The result is a performance vehicle first and an SUV second.

What the brand has not disclosed is pricing, and that gap sits noticeably at the center of the launch. Buyers know the power, the range and the room, but the sticker is held back until closer to the on-sale window. Expect the final number to sharpen the SUV-versus-sedan question.

All three trims are expected to reach U.S. showrooms next summer. Until then the GT SUV exists as a set of specifications rather than a purchase, and the only open variables are the price and the EPA range figure that will replace the forgiving WLTP estimate.

The electric GT family has now grown from a single sedan into a two-body lineup, and the SUV is the volume play. Mercedes-AMG has said nothing about a wagon or a further GT derivative, but the SUV itself is enough to widen the nameplate's reach considerably.
