Mercedes-Benz EV Platforms

EVA2 · MMA · MB.EA · MB.OS

Mercedes's first EVs were efficient but expensive and slow to charge. The 800 V CLA on MMA is the first car where Mercedes owns the drive unit, the software and the efficiency lead together.

Mercedes-Benz moves from first-generation EVs to dedicated architectures. 2021-2025: EVA2 (EQS, EQE at 400 V), MFA2-based EQA and EQB, van EVs (eSprinter, eVito) and the G 580 with four motors. From 2025, all 800 V: MMA (CLA, GLA, GLB), MB.EA (GLC and C-Class EVs), VAN.EA (VLE and VLS vans) and AMG.EA with YASA axial-flux motors. In China: CATL cells, Momenta driver assistance and Beijing Benz (BBAC) production, with China-spec CLA and GLC.

Finding

Mercedes-Benz has rebuilt its EV lineup on four 800 V architectures, with MB.OS and an in-house two-speed drive unit, after its EVA2 cars sold below plan

EVA2 gave the EQS a 108-118 kWh pack and a drag coefficient of 0.20, but at 400 V and with domain electronics, and the EQS and EQE sold well below plan. The 2025 CLA on MMA runs at 800 V with an 85 kWh pack, up to 320 kW charging and a rear drive unit with a two-speed gearbox and silicon carbide inverter, designed in-house. It is the first car on MB.OS, with four domain computers and a zonal power network.

MB.EA carries the same approach to the GLC with EQ Technology (Bremen, 94 kWh, 330 kW) and the electric C-Class. AMG.EA adds axial-flux motors from YASA, the British company Mercedes bought in 2021, for the AMG GT four-door. VAN.EA underpins the VLE and VLS vans from Vitoria and Jawor. EVA2 cars and the MFA2-based EQA and EQB run out as replacements arrive.

China shapes the software. The China-spec CLA uses driver assistance from Momenta, Mercedes buys cells from CATL in Europe and China, and Beijing Benz builds EVs for the domestic market. Mercedes also owns half of smart, whose cars ride on Geely's SEA platform (see Geely EV Platforms), and a stake in the ACC cell venture with Stellantis.
