MERCEDES-BENZ HAS ENGINEERED a new powertrain that aims to revolutionize vehicle efficiency. Developed to push the limits of production models, as previewed in the Vision EQXX concept car, the next-generation electric drive system raises the bar for the brand and automakers across the globe.
As demonstrated in the EQXX, the powertrain is chock-full of advances that deliver solutions to the main sticking points consumers have with battery-electric vehicles: charging speed and range. The drive system will be housed within the new Mercedes Modular Architecture in the future CLA Class vehicles.
“The Concept CLA Class is the forerunner for an entirely new all-electric segment of entry-level vehicles at Mercedes-Benz. The range will comprise a total of four new models—a four-door coupé, a shooting brake and two stunning SUVs—each with significantly elevated product substance,” said Ola Källenius, chairman of the board of management of Mercedes-Benz Group AG. “This new model family is inspired by a generation of car buyers who want that unmistakable Mercedes-Benz feel, with more features, even greater comfort and safety and the most advanced technology. They also seek a sustainable choice that is a cut above the rest.”
To be tuned to the specifications of a road-worthy production model, the powertrain lost some efficiency. CLA will have 93 percent energy efficiency from the battery to the wheels when long-distance driving, as opposed to EQXX’s 95 percent.
When transferring the technology to a production model, the powertrain had to be made durable and cost-effective. “It’s one thing to go around the globe a couple of trips; it’s another thing to do 200,000 kilometers [124,274 miles],” Christoph Starzynski, vice president of vehicle engineering and overall vehicle functions at Mercedes-Benz Cars told Newsweek at CES annual consumer electronics trade show.
When the CLA Class comes to life, it will be available with two battery chemistries—one traditional and the other with a silicon-oxide anode design to allow for high-energy density.
The next-generation battery technology will allow for a range of more than 466 miles on a single charge, as measured on the European standard WLTP testing cycle. That is more than a Tesla Model S, thou
