company news about Technical Brief: Mercedes-Benz Electric Vehicles (EVs)

Overview

Mercedes-Benz has strategically expanded into the electric vehicle (EV) segment under its EQ sub-brand, offering luxury battery electric vehicles across multiple segments. As of 2025, the EQ lineup includes models such as the EQA, EQB, EQC, EQE, EQS, and EQV, along with upcoming EV variants of core models (e.g., the electric G-Class and electric CLA). These vehicles embody the brand's signature luxury combined with state-of-the-art EV technologies.

Platform & Architecture

• EVA2 (Electric Vehicle Architecture 2)

  • Used in models like EQE Sedan/SUV and EQS Sedan/SUV

  • Purpose-built EV architecture with flat battery integration, long wheelbase, and flexible cabin design

  • Supports RWD and AWD (dual motor) configurations

  • High-voltage 400V electrical system

• MFA2 (Modular Front Architecture)

  • Used in EQA, EQB, and EQC (compact models derived from ICE platforms)

  • Adapted to accommodate electric drivetrain components

  • Less efficient packaging compared to EVA2

• MB.EA (Mercedes-Benz Electric Architecture) (Upcoming)

  • Scalable modular architecture for future midsize and full-size EVs

  • Will eventually replace EVA2

Battery & Powertrain

• Battery Types

  • Lithium-ion battery packs with capacities ranging from 66.5 kWh (EQA/EQB) to 120 kWh (EQS SUV)
