Compared to ICE vehicles, EVs are expensive and heavy
Expensive maybe, IMHO not really, at least in China. Heavy .. this doesn't sound fair. Are you comparing a cherry-picked, heavy, full battery back EV with an empty tank ICE? Noting the EV has far more torque, and that the same tech is used in UAVs and in a ground vehicle you can arguably move the weight around (lower it) easier in an EV, this casual observer (not a car person) would expect superior mass distribution and lower overall weight (certainly vs torque).

Another potential consideration is that the EV is far better placed to use recovered power from braking, so a small amount of additional mass will have less efficiency impact than in a comparable ICE.
- stonogo 3y agoVehicle weight also affects how much wear the roadways experience. I'm not sure "A Corolla weighs less than a truck" is relevant here, especially considering that the F-150 is the most popular vehicle in the US by sales number. Comparing things to the market leader is generally a useful metric.
- speedgoose 3y agoHeavy trucks damage roads much more than cars. It depends on the weight but it’s exponential. The weight difference between an EV and an ICE of the same category is not a big concern to have in terms of road damage. https://en.m.wikipedia.org/wiki/Fourth_power_law https://en.m.wikipedia.org/wiki/Fourth_power_law
