Student engineers from Eindhoven University of Technology (TU Eindhoven) have unveiled a concept electric vehicle designed to capture the microscopic particles shed by tires and brakes as it drives. The team, known as TU/ecomotive, says its VENTRA concept aims to raise awareness of non-exhaust emissions and push the industry toward new solutions, according to Chinese outlet D1EV.
Capturing particles at the source
Although EVs produce no tailpipe emissions, they still release fine particulate matter through the wear of tires, brakes, and road surfaces. The problem may be even more pronounced in EVs, which tend to be heavier and exert greater force on tires during acceleration, said team leader Tim Spencer. “No exhaust emissions does not mean no emissions at all,” he said.
VENTRA's signature feature is its particle capture system, which targets the air around the wheels—where the particles originate. Instead of using a physical filter, the system employs static electricity: it charges the particles and attracts them to a grounded collection surface. The collected material can be vacuumed or washed off, and the team has even recycled it into interior trim. Simulations suggest that at speeds between 50 and 80 km/h (31-50 mph), about 24% of particles can be directed into the collection container, rising to 42% at lower speeds.
Lighter body, cleaner driving
The vehicle is also designed to generate fewer particles in the first place. Its chassis is made largely from lightweight carbon-fiber-reinforced thermoplastic panels, cutting nearly 100 kg (220 lb) from the car's weight. A lighter body reduces stress on tires, slowing wear and lowering particle output.
Driver behavior is another focus. VENTRA is equipped with a “Clean Drive” system that monitors driving conditions and offers suggestions via a dashboard display, encouraging smooth acceleration, gentle braking, and minimal unnecessary steering. These habits not only reduce tire wear but also extend brake life.
The team hopes to highlight the health risks of fine particles, which can penetrate deep into the lungs and even enter the bloodstream, potentially increasing the risk of cardiovascular disease, stroke, and respiratory conditions such as COPD and lung cancer. European regulations are tightening in this area: the new Euro 7 standard, effective November 2026, will for the first time set limits on emissions from brake and tire wear. Spencer said, “With the VENTRA project, we want to show that solutions are possible and encourage the automotive industry to broaden its view beyond the exhaust pipe.”
