The platform designed from the ground up favoring electric vehicles would allow engineers to generate a much higher level of room for passengers and boot space for the same footprint. SpaceĪt the Mercedes-Benz Group 2021 results conference call in February 2022, Källenius had stated that all models based on the MMA platform will measure at least 4 meters 50 centimeters (177.2 in.) in length. The next-gen e-drive unit developed in-house will consist of permanent magnet synchronous motors, SiC-Inverter, a two-speed gearbox on the rear axle, and an 800-volt system. The company will ramp up production of the new eATS, presumably eATS 2.0, in 2023. On April 18, 2022, JESMB reported that Mercedes-Benz will start production of a new in-house developed eATS for compact EVs at the Stuttgart-Unterturkheim plant in September 2022. YASA, a British start-up Mercedes-Benz Group acquired in 2021, will build axial motors for higher performance in Berlin. Production of the radial motors (eATS 2.0) for compact cars will take place at the Mercedes-Benz Untertürkheim plant. Schafer has told Automobilwoche that the company wants to “master” the electric motor, battery, and power electronics. The electric drives for the Mercedes MMA platform models will be built in-house from 2024.

These new materials and production processes could increase range and reduce charging time and cost. In-house developed eMotors with “sophisticated inverter and high voltage technology” and in-house battery R&D with partnerships with battery partners CATL, Farasis, and Sila Nano could bring to fruition next-generation technology that can be easily incorporated into this platform. The shift to the electric-first Mercedes MMA platform would allow engineers to incorporate electric vehicle-specific technologies under development. Starzynski said any compromises in the MMA platform-based models would be in the ICE ones, not the electric vehicles. Unlike the EQA and EQB, the future electric variants of gasoline-engined Mercs will ride on the MMA platform that prioritizes battery-powered pure electric powertrain. In an interview with Motor1, Christoph Starzynski, Vice President for Electric Drive, Mercedes-Benz, spoke about the new platform strategy. So far, we’ve seen automakers, with Mercedes-Benz no exception, launch EVs on vehicle platforms designed for internal combustion engines. MMA, on the other hand, will be an electric-first platform. EVA, which underpins the Mercedes EQS, Mercedes EQS SUV, Mercedes EQE SUV, and Mercedes-Maybach EQS SUV, is a bespoke EV platform. Electric-first platformĪll the new Mercedes electric car launches entering production before 2025, barring the EQG, will be based on either the EVA (Electric Vehicle Architecture) platform or the MMA platform. The future four models would be available with a pure electric powertrain, either as standard or as an option. The company’s ‘Entry Luxury’ portfolio includes all its compact models, and there are currently seven such vehicles in the line-up: (A-Class, B-Class, A-Class Sedan, CLA Coupe, CLA Shooting Brake, GLA + EQA, and GLB + EQB). On May 19, 2022, Schafer revealed in his presentation at the ‘Mercedes-Benz Strategy Update: Economics of Desire’ event that the ‘Entry Luxury’ line-up will include only four models in the future. Currently, the EQA and EQB share the underpinning with their respective internal combustion counterpart (GLA and GLB). The MMA won’t be over-engineered, allowing the compact models to be affordable. The Mercedes MMA platform will thus be exclusive to compact Mercedes electric car models and SUVs, such as the second-gen Mercedes EQA and Mercedes EQB. However, the company has now decided on the ‘MB.EA’ for its future mid-size and large electric cars. Mercedes-Benz was indicating that the MMA platform will underpin its future mid-size electric cars (equivalent to C-Class and GLC) as well. The MMA platform will underpin 4 models in the future, including the next-gen EQA and EQB. “It will form the basis for numerous electric models,” he added. “The next milestone will be our future platform for the compact and mid-size classes,” Ola Källenius, the Chairman of Mercedes-Benz Group’s BoM, said about MMA at the company’s annual general meeting. Initially, the MMA platform’s scope was supposed to be wider than that of the EVA platform that debuted in the EQS. Mercedes-Benz Group to spend EUR 60 billion between 20 Exclusive to compact cars
