As electric vehicles reduce car exhaust as a source of particulate emissions, people are increasingly focusing on other vehicular sources of pollution that won’t go away with electrification. Tires are one of them, particularly as we grapple with overweight EVs with tire-shredding torque. And brakes are another—even an EV with regenerative braking will occasionally need to use its friction brakes, after all.
Over in Europe, the people responsible for writing regulations have taken this into consideration with the upcoming Euro 7 standard, which sets new limits on 10- and 2.5-micron particulate emissions on all new vehicles—including EVs—starting next year. And to help OEMs achieve that target, Brembo has developed a new brake and pad set called Greentell that it says cuts brake dust emissions by 90 percent, improving durability in the process.
“We started 10 years ago to investigate a different solution. The main topic that we had in mind was to develop a disk that is greener than the current production of cast iron,” said Fabiano Carminati, VP of disc technical development at Brembo.
