>Even using the study’s 20% number for EV. vs. gas car weight, this doesn’t handicap EVs much. BEVs produce 38% less total brake, road and tire wear combined, without even taking into account their exhaust benefits.
but more importantly
>Study recommendations
>Taking all this information together, the study makes some recommendations. It obviously points out that fleet electrification will be beneficial in reducing non-exhaust emissions, and suggests that that should continue rapidly.
>**However, it also points out that the total reduction in non-exhaust emissions from shifting drivers to public transport, rather than individual vehicles, can be 5x higher than just electrifying the vehicle fleet alone. So shifting drivers to using public transport should be prioritized when possible. Or, getting people to walk or bike instead**.
TLDR:
electric public transport is the best, second best is electric personal transport( when it comes to air pollution)
No mention of different torque curve, which also impacts tire wear – only weight was considered? While it’s anecdotal, I’ve noticed people tend to enjoy flooring bit more their EVs to see that juicy acceleration.
**TL;DR:**
• A new study quantifies just how much EVs help in cutting harmful exhaust emissions, but also cutting other types of pollution that come from personal vehicles. The study looked primarily at London, Milan and Barcelona.
• It found that BEVs produce 38% less total brake, road and tire wear combined, without even taking into account their exhaust benefits. While an individual car does produce more total emissions per mile as long as that car has higher occupancy than a motorcycle, that means it could fare better in terms of emissions permile.
• The analysis includes an interactive modeling tool where you can examine different types of transport and the amount of emissions they produce, with electric models being the clear winner out of the various analyzed powertrains. It also looked at various “non-exhaust emissions” of road transport, recognizing that as car exhaust becomes cleaner due to greater fleet electrification, other forms of emissions will end up taking over as the dominant pollutants from road transport.
• The results were published in the European Journal of Transport.

What about manual transmissions vs conventional? Ive got an ICE with 140000km, original brake pads at 80% and I tow a trailer once a week.
This makes no sence. An ICE car from came year can be as good if the driver is good and the materials are the same.
The thing is that EVs have mostly break by wire and computer assisted to maximize regeneration. Most modern ICE cars also have the same breaking assists
