Mercedes-Benz has unveiled the 2027 CLA Hybrid, introducing a new electrified drivetrain and software architecture aimed at improving efficiency while maintaining everyday usability. The model is positioned as a transitional offering between conventional combustion vehicles and fully electric models.
At the core of the CLA Hybrid is a newly developed 1.5-liter turbocharged four-cylinder engine using the Miller combustion cycle, paired with a 48-volt mild-hybrid system. The setup is designed to reduce fuel consumption and emissions, particularly during partial-load driving, while preserving performance. Mercedes-Benz said the powertrain reflects its broader strategy of combining electrification with advanced internal combustion technology.

The hybrid system delivers a combined output of 208 horsepower and 280 lb-ft of torque, enabling a 0–60 mph time of about 7.1 seconds. The powertrain supports limited electric-only driving at low speeds and allows “electric gliding” at speeds of up to 60 mph, where the combustion engine can decouple and shut off during coasting. Energy recuperation of up to 25 kW is available across all eight gears.
The 1.5-liter engine, designated M 252, produces 188 hp and 221 lb-ft of torque on its own. It is mated to a new eight-speed electrified dual-clutch transmission (8F-eDCT), which integrates a 30 hp electric motor and inverter within the transmission housing. Energy is supplied by a 48-volt lithium-ion battery with 1.3 kWh of usable capacity.
Mercedes-Benz said the system enables smooth transitions between electric and combustion driving, with the electric motor also replacing a conventional starter motor. An electrically driven air-conditioning compressor allows climate control to function even when the engine is switched off.

The 2027 CLA Hybrid is the first model to debut Mercedes-Benz’s new operating system, MB.OS. The software platform connects the vehicle to the Mercedes-Benz Intelligent Cloud and supports over-the-air updates for infotainment, vehicle functions and driver assistance systems.
The latest generation of the MBUX infotainment system runs on MB.OS and integrates artificial intelligence technologies from Microsoft and Google. Navigation is powered by Google Maps and enhanced by Google Cloud’s Automotive AI Agent, while conversational voice functions are designed to handle more complex, multi-step interactions.
Standard driver assistance features include Distance Assist DISTRONIC, Lane Keeping Assist and Blind Spot Assist Plus with Exit Warning. Optional systems add functions such as Steering Assist and automated lane changes triggered via the turn signal.

Inside, the CLA Hybrid can be equipped with the optional MBUX Superscreen, spanning the dashboard with a 10.25-inch driver display, a 14-inch central touchscreen and a 14-inch passenger display. Mercedes-Benz said it has reinstated physical controls on the steering wheel following customer feedback, including dedicated switches for cruise control and audio volume.
With the 2027 CLA Hybrid, Mercedes-Benz is positioning the model as a technologically advanced compact sedan that blends electrification, software-driven features and traditional combustion engineering as part of its broader product transition.
