Mercedes-Benz debuts the MMA architecture in the upcoming CLA sedan, combining silicon-anode battery chemistry and an innovative two-speed dog-clutch gearbox for 93% efficiency.

Efficiency Record: Deriving technology from the Vision EQXX prototype, the production 2026 Mercedes-Benz CLA Electric achieved 12kWh per 100km energy consumption during certified WLTP dynamic drive cycles.

Two-Speed Drive Architecture

While first gear provides punchy low-speed acceleration (0-60 in 4.8s), second gear shifts at 68mph to drop motor RPMs by 34%, dramatically reducing back-EMF losses during high-speed autobahn cruising.

800V DC Fast Charging

With a peak intake of 320kW, the CLA adds 248 miles of driving range in 15 minutes, supported by real-time predictive navigation battery pre-conditioning.
