The Ultimate AMG Power

A New Era for AMG: The Concept GT XX

Mercedes-AMG has unveiled its future electric flagship with the Concept GT XX, a groundbreaking four-door vehicle that showcases an advanced technical layout, a radical design, and a motorsport-inspired cockpit. This fully operational machine features a 1,341bhp tri-motor electric drivetrain and an oil-cooled 114kWh cell-to-pack battery capable of charging at up to 850kW. The GT XX serves as a technology demonstrator for what will become the highly anticipated successor to the GT 4-Door Coupé and the most powerful AMG yet.

Design Innovations

The GT XX is the first model built on the new AMG.EA electric car platform. Its battery pack is integrated into the chassis to enhance torsional rigidity and crash protection. The body is constructed from a mix of aluminium, steel, and carbon fibre composites. It introduces a completely new look for AMG, merging elements of sports cars and grand tourers. The design includes a long bonnet, cab-back profile, and tapering rear end, inspired by the Vision AMG of 2022.

One of the most striking design elements is the reshaped Panamericana grille, which takes on a more concave, oval form with 10 vertical strakes. This is flanked by recessed headlights and a deep splitter. Functional vents on the bonnet extract heat, while the windscreen is steeply raked for improved aerodynamics. The roof features a defined central channel, and frameless doors with flush handles and compact aero mirrors reduce drag.

At the back, the concept is missing a rear window, with six small round tail-lights joined by a 730-LED light panel that can display messages. An airbrake spoiler deploys under heavy braking or at high speed, working in tandem with a large carbon fibre diffuser. The 21in alloys feature active blade sections that open to aid brake cooling and close at speed to reduce drag.

Aerodynamic Efficiency

All these design elements combine for a drag coefficient of 0.19, making the production model one of the slipperiest cars on sale. While not as low as the EQXX’s record-breaking 0.17, the brief for the GT XX was to prioritize downforce and cooling over outright drag reduction. A complex underfloor aerodynamic package is designed to generate a venturi effect, contributing to “exceptional aerodynamic balance.”

The GT XX measures 5,204mm long, 2,130mm wide, and 1,317mm tall, making it longer, wider, and lower than the current V8-engined GT 4-Door Coupé. These dimensions are expected to carry over into the production car, which will be built at Mercedes-Benz’s Sindelfingen manufacturing facility in Germany.

Powertrain Breakthroughs

The heart of the GT XX is its tri-motor drivetrain: two axial-flux motors at the rear, with a third up front that can decouple under light loads to reduce mechanical drag. Combined output is 1,341bhp, sent to all four wheels via a fully variable 4Matic+ system. These motors, created by Mercedes-owned UK manufacturer Yasa, will be used by all electric AMGs and the most powerful Mercedes-Benz models.

Electricity is drawn from the 114kWh oil-cooled cylindrical-cell battery, developed in partnership with AMG’s Formula 1 powertrain division. Oil immersion offers greater surface area and more efficient heat transfer under sustained load than conventional liquid cooling. Operating at “more than” 800V, the battery theoretically supports DC charging at up to 850kW, although no public chargers currently offer such capacity.

Emotional Appeal and Interior Design

AMG has gone to great lengths to retain the emotional appeal of its V8-powered models. An eight-speaker exterior sound system mimics acceleration sounds, while the interior mixes luxury saloon cues with GT3 race car elements. Dual digital displays (10.25in and 14in) dominate the dash, and the steering wheel is inspired by the AMG One. Illuminated orange piping echoes the car’s high-voltage cabling, and seats feature 3D-printed ergonomic inserts.

Experimental materials adorn the interior, including biotech leather alternatives made from recycled GT3 tyres, protein-derived bio-silk door pulls, and a visible-from-the-inside carbon fibre roof with no headliner. Even the floor uses recycled material, printed in a chequered-flag pattern.

Future Plans and Market Position

The GT XX’s production model will be joined by a closely related SUV, scheduled for UK launch in 2027, aimed at taking on the upcoming electric Porsche Cayenne. However, the unveiling comes as several performance car makers scale back their electric model plans. Ferrari has reportedly delayed its second electric model until at least 2028, while Lamborghini, Porsche, and Maserati have also postponed or cancelled forthcoming electric models.
