If you include e-bikes and e-scooters as EVs, sure. If you mean cars and trucks, the F150 Lightning, the EV6, the Ioniq 5, the EX30, and every other vehicle is heavier than its ICE counterpart. The motors are inherently torquier too.
disclaimer: I drive an electric car but would sell it in a heartbeat if I could use transit or bikes to safely and efficiently get to work, the grocery, and the doctor.
- jeffbee 2y agoThey aren't inherently torquier. That's a design point.
- oasisaimlessly 2y agoIf they're heavier, they inherently need more torqure to have acceleration competitive with ICE vehicles.
- MengerSponge 2y agoIt's Lenz's Law, friend. It's as much a design point as a=F/m. Because of it, induction motors and magnet synchronous motors generate more torque at 0RPM than any combustion engine I've heard of. You could have software limiters, but you'd need regulatory mandates for that. Actually, I support that. 3+ ton trucks with a sub 4s 0-60 shouldn't be street legal. Or they should at least require a special license and liability insurance.
- jeffbee 2y agoAll EVs already use limiters because, as you correctly noted, just shorting the battery across the motor will rip the axles off and set the battery on fire. The question of whether an EV should put down grip-limited amounts of torque, or should limit itself to .5g at most, is a question of tuning.
- MengerSponge 2y agoSo... you're saying electric motors are inherently torquier?
