Vision EQXX – Innovative Chassis System for a Highly Efficient Electric Vehicle

Abstract

With Vision EQXX, Mercedes-Benz brings a highly efficient electric vehicle on the road to show the ultimate performance of its new EV-platforms.

This presentation will give an insight in the development of the chassis for this unique project.

Stepping into the electric-only future with rear-wheel drive makes a complete new chassis system necessary. Main point is the all-new compact rear axle that fits perfectly to the electric powertrain and brings the efficiency to the road.

Just like the entire vehicle, also the chassis with its sub-systems pulls all the major efficiency levers to boost the overall performance of the vehicle. Ultra-low rolling resistance tyres, innovative aluminium brake discs and a lightweight rear-axle subframe (developed in close cooperation with Mercedes-Benz Formula1 Team) are only some examples of the efficient solutions.

Beside the innovative solutions throughout all the chassis sub-systems, the agile working model in this project is remarkable, too. In only a short development-period the whole chassis must be designed, realized and tuned to bring EQXX on the road in time.
