Mercedes-AMG has unveiled the Idea AMG GT XX, an electrical expertise demonstrator that gives perception right into a forthcoming four-door series-production sports activities automotive. The idea options three axial flux motors delivering over 1,000kW peak output and a prime pace exceeding 360 km/h.
The automobile represents Mercedes-AMG’s transition to electrical efficiency automobiles based mostly on the corporate’s high-performance AMG Electrical Structure (AMG.EA). The idea incorporates expertise developed throughout a number of Mercedes services, together with the Components 1 drivetrain workforce at Mercedes-AMG Excessive Efficiency Powertrains in Brixworth, UK.
“The perfect minds in our world R&D community have contributed their intensive experience,” mentioned Markus Schäfer, Member of the Board of Administration of Mercedes-Benz Group AG and Chief Know-how Officer, “From Mercedes-Benz in Sindelfingen and Untertürkheim to Mercedes-AMG in Affalterbach and Yasa within the UK to our Components 1 drivetrain consultants at Mercedes-AMG Excessive Efficiency Powertrains in Brixworth. Collectively, they’ve developed the Idea AMG GT XX and are offering an perception into pioneering drivetrain expertise and the way forward for efficiency.”
The drivetrain system makes use of axial flux motors initially developed by Yasa, a wholly-owned subsidiary of Mercedes-Benz AG. These motors provide roughly thrice the facility density of typical radial flux motors whereas being two-thirds lighter and occupying one-third of the area. The motors will enter collection manufacturing at Mercedes-AMG in 2026.
“The Idea AMG GT XX is the following milestone within the historical past of AMG and forges an entire new dimension of efficiency,” mentioned Michael Schiebe, CEO of Mercedes-AMG GmbH. “We’re bringing groundbreaking expertise that redefines excessive efficiency. And the perfect factor is that this automotive is a real AMG with each fibre of its being.”
The idea options two Excessive Efficiency Electrical Drive Models (HP.EDUs) – one on the entrance with a single motor and one on the rear containing two motors. The entrance unit features as a booster motor that engages when extra energy or traction is required. A Disconnect Unit decouples the entrance motor throughout regular driving to enhance effectivity.
The automobile incorporates a brand new Excessive Efficiency Electrical Battery (HP.EB) developed utilizing expertise from the AMG ONE hypercar and Components 1 expertise. The battery makes use of cylindrical cells with laser-welded aluminum housings and full-tab configuration to cut back inner resistance. Cell chemistry relies on NCMA (nickel/cobalt/manganese/aluminum) with silicon content material within the anode, offering 300 Wh/kg vitality density.
Direct cooling expertise utilizing electrically non-conductive oil flowing round every cell maintains optimum temperature. The system contains greater than 3,000 cells working at over 800 volts. The idea can recharge vitality for about 400 kilometers of vary in round 5 minutes, attaining common charging energy exceeding 850kW at 1,000 amperes.
For charging infrastructure, Mercedes-Benz collaborated with Alpitronic to develop a prototype charging station able to transmitting excessive present through commonplace CCS cable. The corporate plans to broaden its Mercedes-Benz Charging Community with next-generation high-performance charging stations for future manufacturing fashions.
The idea’s physique construction combines aluminum, metal, and fiber composite supplies for stiffness whereas sustaining low weight. The high-voltage battery is centrally built-in into the skateboard construction with outlined lateral load paths for crash security. Aerodynamic options embody a drag coefficient of 0.198 regardless of extensive high-performance tires.
Notable improvements embody luminescent paint segments utilizing electroluminescence expertise, audio system built-in into the entrance headlights, and an MBUX Fluid Gentle Panel with over 700 programmable RGB LEDs on the rear. Inside supplies embody biotechnology-based leather-based alternate options produced from recycled racing tires and biotech silk made utilizing genetically modified micro organism.
The idea options energetic Aero Wheels with movable blades that shut to cut back drag or open for brake cooling. Every wheel incorporates an autonomous actuator powered by a mini-generator that makes use of the spinning wheel to supply electrical energy, speaking wirelessly with the automobile’s management unit through Bluetooth.
Gorden Wagener, Chief Design Officer Mercedes-Benz Group AG, mentioned: “The brand-new CONCEPT AMG GT XX embodies the recent a part of our design philosophy of sensual purity.”
