Weight isn't as big a concern with EVs because they require more energy to accelerate, but they get more energy back when regeneratively braking. The biggest impact on EV range is aerodynamic, by a long shot. The F-150 lightning, for example, has the same efficiency with the standard and extended range batteries, even though the extended range battery is 500 lbs heavier.
Weight still contributes to tire and brake wear which causes particulate pollution, makes handling worse, and makes crashes more energetic.
I don't think that's what the op was arguing with. I think they were just saying that weight is not the first thing that needs optimized here.
Yeah absolutely. I never said anything to the contrary. There are reasons to reduce EV weight, but range ain't one of them.
230 miles on 98 kWh capacity = 0.4260 kWh per mile
Vs
300 miles on 131 kWh capacity = 0.4366 kWh per mile
Is that significant? Eh... But at the same time I wouldn't throw 500 lb weights in the back and drive around claiming it didn't impact performance.
Yeah, you put it in the driver's seat
Ayyyoooooooo
