Here’s a car which could finally put all the milk float jokes to bed and give Porsche a headache. Mercedes has pulled the wraps off its CONCEPT AMG GT XX, a four-door coupe with 1,360 hp, a top speed of 2234mph and the ability to add 250 miles of range with a five minute charge.
The concept hints strongly at a new AMG model to replace the existing petrol powered GT and uses three axial flux motors and a high performance battery developed from scratch in conjunction with the AMG Formula 1 team.
Its technological underpinnings were originally developed by British electric motor specialist YASA. Thanks to a peak output of over 1,000 kW – or 1,360hp - the CONCEPT AMG GT XX can reach claimed top speeds of more than 224mph.
The battery remains in an optimal temperature range even during fast driving, enabling extra performance but also extremely fast charging. The concept vehicle can recharge energy for about 400 kilometres of range – that’s 248 miles - in around five minutes.

The innovative motors are around two-thirds lighter and take up just one third of the space of conventional motors.
The high-voltage battery benefits from all the experience from the AMG ONE supercar and Formula 1 as well as the knowledge of engineers from Mercedes-AMG in Affalterbach and Mercedes-AMG High Performance Powertrains (HPP) in Brixworth (UK).
The new battery cell design uses cylindrical cells that are unusually tall and slim. This format delivers benefits for cell cooling.
This allows the CONCEPT AMG GT XX to achieve a very high average charging power of more than 850 kW at 1000 amperes over a wide range of the charging curve.
Mercedes says it will expand the infrastructure of its own Mercedes-Benz Charging Network with the next generation of high performance charging stations to allow top ups at this speed.
The looks of the concept are shaped by aerodynamics. At 300 km/h, around 83 percent of the drive energy is required to overcome drag. Aspects include the sporty flat shape, sharply raked windscreen, low-slung bonnet, angled side windows and the absence of a rear windscreen, such as in a Polestar 4.

The interior of the GT XX is less fussy than most Mercedes models, and immersed almost completely in black. Visible body structures and interior components inspired by high-voltage cables create a close connection to motorsport. All the instruments are controlled via two large LCD displays: the 10.25-inch cluster and the 14-inch multimedia touchscreen. The displays are ergonomically angled towards the driver and have a seamless-glass look.
Another innovation is the fitment of exterior speakers for emitting driving sounds in the front headlights. The integration saves space, reduces weight and enables new sound variants. In addition, the speakers also serve as signals for pedestrian protection.
At the rear, a light panel with more than 700 freely programmable RGB LEDs allows information from the vehicle can be displayed as text or animation. It can show a variety of content, such as a digital AMG logo or the current charging process.

Another highlight is the active Aero Wheel, which aims to resolve the conflict between brake cooling, aerodynamic efficiency, and maximum range. The 21-inch forged aluminium wheel is equipped with five movable elements. These blades can seal the wheel flush to improve range and reduces energy consumption. They can also actively open the blades to pump cooling air through the wheel to the brake and back out again.
The actuator uses Bluetooth to communicate wirelessly with the control unit in the vehicle and generates its own power.
A production version of the car is expected in 2026, and as with the Porsche Taycan there will be less extreme (and expensive) versions.
