Mercedes-Benz has finally revealed details about the revolutionary powertrain in its upcoming next-generation CLA. Set to launch in 2025, it will be the first model built on the Mercedes-Benz Modular Architecture (MMA), which will also underpin two future SUVs and a shooting brake.
Leveraging the groundbreaking technology developed for the Vision EQXX concept, the MMA platform incorporates an 800V electrical system and a silicon carbide (SiC) inverter for enhanced efficiency and performance.
The all-electric CLA will debut Mercedes-Benz’s Electric Drive Unit (EDU) 2.0, marking a new era for the brand’s electric drive systems.
This rear-wheel-drive system features a 272 hp electric motor, high-performance power electronics with a SiC inverter, and a two-speed transmission.
For enhanced traction, the next-generation CLA will also offer the brand’s 4MATIC all-wheel drive system. This adds a front-mounted electric motor that provides an additional 109 hp when needed for extra power or traction.

A Disconnect Unit (DCU) decouples the front axle’s electric motor to improve efficiency. This is the first time Mercedes-Benz has used a DCU in its entry-level segment. This technology contributes to the targeted WLTP range of 750 km, as demonstrated in the Concept CLA Class.
Two battery chemistries will be available: a nickel manganese cobalt (NMC) pack with 85 kWh and a lithium iron phosphate (LFP) battery with 58 kWh. The CLA will be the brand’s first production car with an 800V electrical architecture, enabling super-fast DC charging at up to 320 kW, adding 300 km of range in just 10 minutes.
AC charging is also available at 11 kW or 22 kW, and Mercedes-Benz plans to add bi-directional charging (V2L) to future entry-level models. The CLA also offers four levels of regenerative braking, with a maximum recuperation rate of 200 kW.
To showcase the CLA’s electric powertrain, Mercedes-Benz conducted “Project N,” a 24-hour endurance test at the Nardo high-speed test track in Italy.
A near-production CLA prototype covered 3,717 km with 40 charging stops, each lasting around 10 minutes, achieving an average speed of 154.9 km/h.
For those not yet ready to go fully electric, Mercedes-Benz will also offer the new CLA with a 48V mild-hybrid system, featuring the new M252 engine from the company’s FAME (Family of Modular Engines).
The M252 is a 1.5-litre four-cylinder engine that uses the Miller cycle for improved fuel efficiency, and will be offered in three power outputs – 136 hp, 163 hp, and 190 hp. It’s paired with a new eight-speed dual-clutch transmission with an integrated 27 hp mild-hybrid electric motor.
