I compared the weights of EVs versus ICE, and they were surprisingly close. Most of time, the differences were in the 15% range, and then you find exceptions like the Hummer, which is 30% heavier. I'm sure it comes as no surprise That the heavier the vehicle, the bigger the difference in ICE versus EV weight.
While I think lighter weight vehicles of all types would be a big win, I fear that ship has sailed. I think we have an opportunity to reset vehicle size both from a desire for cheaper and simpler vehicles. Look at cost and weight of the BYD EVs and the new pickup trucks from Slate and Telos.
Overall, I find the slightly increased weight for an EV to be an acceptable trade-off. Brakes last longer, tires, depending on make, are about 10% shorter life at most and overall maintenance is much less. Since I keep my cars until the body goes toes up, I have a much lower carbon footprint. than the 3yr lease route
If you give the difference in weight as a percentage, it is sort of surprising that the percentage is higher for heavier vehicles, right? Or at least I don’t get it. I’d expect the EV to be a constant factor heavier, a total weight of combustion_vehicle*1.1 or something.
I wonder if it's sorta like the rocket equation. A heavier vehicle requires larger batteries to move the extra weight with a comparable range as a smaller vehicle, but the batteries are heavy too, so you need even more battery to move the heavier batteries.
It's exactly that. Battery = heavy, heavy vehicle = short range. I wonder if ICE vehicle weight is calculated with a full fuel tank? Gas / Diesel is also pretty heavy and large vehicles have large empty spaces to be filled with fuel.
I had a 2010s Civic and moved to a Model 3. The curb weight difference was only ~3-400 lbs (about 10%), but the larger battery capacity, large SUV offerings are significantly heavier than ICE options (the F150 Lightning is about 2,000 pounds heavier than an ICE F150, for example, 5,000 -> 7,000 lbs.).
The 8th Gen Civic in heaviest config was about 2900lb. The lightest model 3 is about 3500lb. 600lb best case. The lighter config Civic was 2500lb (not usdm iirc) vs the heaviest model 3 being 4000lb.
