Electric vehicles produce no exhaust emissions, but they still generate particulate matter through tire, brake and road surface wear. In fact, due to the weight of their battery packs, electric vehicles can be up to 40% heavier than comparable combustion-engine vehicles. This additional weight can increase tire wear, a phenomenon also known as the EV paradox.
The significance of this challenge is considerable. According to research, non-exhaust emissions, such as tire, brake and road surface wear, now account for up to 77% of PM10 and 60% of PM2.5 emissions from road transport.
With the innovative VENTRA concept car, TU/ecomotive, a student team from Eindhoven University of Technology, demonstrates how these emissions can also be addressed.
ENS Clean Air contributed to this project as a development partner. With our expertise in particulate matter, airflow and electrostatic air purification, we support the development of technologies that capture particulate matter while driving.
On September 22, 2026, VENTRA was unveiled during an event in Eindhoven. A team of approximately 40 students spent a year developing this innovative concept car. They developed VENTRA around the principle of REDUCE – MONITOR – COLLECT. The electric concept car combines a lightweight structure with smart technology that encourages more conscious driving behaviour and an innovative system that captures particulate matter while driving.
By using lightweight materials, the team reduced the weight of the chassis by approximately 95 kg compared to a conventional design. In addition, the Clean Drive system encourages drivers to accelerate, steer and brake more smoothly, helping to reduce wear and the formation of particulate matter.
ENS Clean Air supported the student team with technical knowledge and advice during the development of the T.R.A.C.E. system (Tire and Road Abrasion Capture by Electrostatics). This system collects air from around the wheels and uses electrostatic technology to separate particulate matter from the airflow and retain it on collection surfaces.
Simulations indicate that the system can capture over 24% of particulate matter at speeds between 50 and 80 km/h. At lower speeds, the simulated capture efficiency increases to 42%, as fans help direct more air into the system.
VENTRA demonstrates how technical innovation and collaboration can contribute to reducing air pollution.
