Is there an explanation why BEVs fare better than hybrids in terms of brake dust? They use the same principle, so I expected similar performances. The article gives no clues, only these results: > It turns out that BEVs reduce the amount of brake dust by 83% [...] Other vehicles that use regenerative braking reduced brake emissions too, with Hybrids reducing them by 10-48%, and PHEVs by 66%.
