Mercedes-Benz is finalizing the next generation of its stylish CLA sedan, set for an official debut next year. This new model will showcase Mercedes’ latest advancements in powertrain technology and software, giving a sneak peek into the brand's future direction. In a preview, the automaker released images of a camouflaged CLA being driven around a test track in southern Germany by Mercedes-Benz CEO Ola Källenius.
The upcoming CLA will be the first model to run on MB.OS, Mercedes’ new operating system built on Linux and incorporating QNX in a hypervisor for critical functions, such as dashboard displays. CEO Källenius emphasized that while MB.OS will support third-party integrations, Mercedes is fully in control of the system’s architecture. "We are the full architects of the stack. That doesn't mean we need to program every line of code. It doesn’t make technological sense, and it doesn’t make economic sense," he explained in an interview.
Mercedes' First In-House Electric Powertrain
Alongside its new operating system, the CLA will feature Mercedes-Benz’s first true in-house electric powertrain. While the automaker has historically collaborated with partners like Bosch for EV powertrains, the CLA represents Mercedes' commitment to a fully independent approach. The powertrain concept was initially tested in the EQXX, an ultra-efficient EV capable of nearly 750 miles on a single charge, which provided insights into Mercedes’ EV engineering vision.
When Mercedes adapted this powertrain to a less aerodynamic EQB model, it still achieved an impressive 5 miles per kWh, an 80% improvement over the existing EQB’s performance. To further prove the new powertrain’s efficiency, a CLA prototype was taken to the Nardo test track in southern Italy. There, it covered 2,309 miles (3,716 km) in 24 hours, beating Porsche’s 2019 record by 181 miles (291 km), averaging 95 mph (153 km/h) with only 10 recharge stops totaling just under seven hours of downtime.
A Gasoline Version to Accompany the EV
Unexpectedly, Mercedes also revealed plans for a new gasoline-powered version of the CLA. As reported in February, Mercedes is taking a more flexible approach to electrification, aiming to offer both electrified and fully electric models to suit a global market that may not be ready to fully transition to EVs by 2030. This gas version will include a 48V mild hybrid system and feature an internal combustion engine sourced from Horse Powertrain Limited, a joint venture between Geely and Renault.
This dual powertrain approach in the upcoming CLA signifies Mercedes-Benz’s commitment to a balanced future, blending cutting-edge EV technology with versatile hybrid options.
