Mercedes-Benz has taken the automotive world by storm with the reveal of its sleek and futuristic hypercar concept, the Vision 111. Showcased in Carlsbad, Calif., this groundbreaking concept pays tribute to the iconic C111 prototypes of the past while introducing revolutionary advancements in powertrain technology.
With a focus on smaller, lighter, and more powerful electric motors, Mercedes aims to reshape the future of electric vehicles (EVs).
Revolutionizing Powertrain Technology
At the heart of the Vision 111 concept lies an ambitious design philosophy centered around wheel-mounted electric motors. Traditionally, wheel-mounted motors have been deemed impractical due to their increased unsprung weight, which adversely affects suspension design.
However, Mercedes, in collaboration with YASA Ltd., a British electric vehicle motors startup, has found a solution. The concept showcases the use of axial-flux (AF) stator technology, which reduces the weight and volume of the motors while delivering enhanced power output.
Weight Distribution and Space Utilization
The adoption of wheel-mounted motors brings numerous benefits to the Vision 111 concept. With the reduced weight of the AF motors, the unsprung weight concern is mitigated. This allows for smaller friction brakes, as the motors in regenerative systems contribute significantly to the braking process.
Additionally, the absence of driveshafts and a central drive unit further reduces weight, creating the opportunity for increased space utilization. The central area of the vehicle can be utilized for housing battery packs, technical components, or even providing additional space for passengers or cargo.
YASA’s Technological Breakthrough
YASA Ltd., the brainchild of Oxford-graduate Tim Woolmer, has been instrumental in the development of the AF motors used in the Vision 111 concept. Overcoming previous cooling and manufacturing challenges associated with axial-flux designs, YASA achieved a major milestone by introducing a new material called soft magnetic composite.
This innovation, coupled with other advancements, allowed YASA to revolutionize AF motor technology. Notably, YASA’s motors powered a prototype that made history by becoming the first EV to triumph in the Pike’s Peak Hillclimb. Ferrari, renowned for its commitment to performance, has also adopted YASA’s motors for its electrified production models.
A Dual-Option Approach
Mercedes-Benz’s forward-thinking approach is evident in the Vision 111 concept, which offers flexibility in powertrain design. The concept can be configured with either centrally mounted or wheel-mounted motors.
This dual-option approach showcases Mercedes’ commitment to exploring different possibilities and finding the optimal solution for future production vehicles. While the first application of YASA motors in a production car is expected to feature centrally mounted motors in a sports car, the potential for wheel-mounted motors is a tantalizing prospect.
Mercedes’ Future Vision
The Vision 111 concept represents just one facet of Mercedes’ vision for the future. The company continues to enhance its radial-flux (RF) motors, which will power the upcoming lineup of small EV cars and crossovers built on Mercedes’ new MMA architecture.
The focus on refining RF motor technology underscores Mercedes’ commitment to delivering exceptional performance and efficiency across their entire EV portfolio.
A Glimpse into Luxury and Technology
The Vision 111’s unveiling concluded a symposium that highlighted Mercedes’ position as a leading luxury brand and provided a glimpse into its future offerings. Attendees had the opportunity to experience the 2024 E-Class sedan, featuring state-of-the-art features such as the Superscreen, NFT artworks, augmented reality, and personalized user-interface graphics.
Mercedes-Benz’s commitment to innovation, both in powertrain technology and the overall luxury experience, sets a new benchmark in the automotive industry.
Shaping the Future
Mercedes-Benz’s Vision 111 concept represents a remarkable leap forward in the world of electric hypercars. With the integration of wheel-mounted electric motors and the utilization of YASA’s groundbreaking AF technology, the concept offers tantalizing possibilities for the future of EVs.
Mercedes’ commitment to advancing powertrain technology, along with its dedication to luxury and innovation, solidifies its position as a pioneering force in the automotive industry. As we eagerly await the next chapter, the Vision 111 serves as a compelling preview of the electrifying future that awaits us.
