Mercedes-Benz Develops In-Drive Brake Technology

Mercedes-Benz is innovating its braking system for electric vehicles (EVs) with a new technology called In-Drive, which relocates brakes from behind the wheels to inside the electric motor housing. This system, currently in active testing, utilizes a water-cooled, friction-based design that can potentially lower operating costs and reduce environmental impact by minimizing brake dust emissions. With regenerative braking handling 98% of stopping power, the In-Drive system is primarily engaged for emergency situations, allowing for a longer lifespan of brake components. The integrated design could also enhance vehicle handling by redistributing weight, moving 200 pounds of unsprung mass away from the corners. Mercedes engineers are experimenting with different cooling fluids to optimize heat management, as the friction brakes can generate significant heat during hard stops. The technology aims not only for improved performance but also to meet rising sustainability standards and address health concerns related to brake dust pollution.
