AFAIK the range benefits you'd get from a smaller electrical motor are minimal, and in the cost of a vehicle the bigger motor doesn't add a huge cost.
Also, a bigger motor can be more reliable, if you're not running it at full bore you've probably got better heat dissipation so it will last longer.
The other issue is people's addiction for large vehicles; bigger vehicle means bigger battery means more weight means more power needed to move everything. As an example a Blazer EV weighs 25-35% more than the ICE version. Take that with the comments about reliability, it counter-intuitively makes a lot of sense that the Blazer EV has a 500hp motor vs the 200-300HP in the ICE.
As far as 'acceleration' itself, Acceleration tends to be more of a factor of torque curve. Electric motors tend to give lots of torque very quick... I accidentally chirp the tires on my Ford Maverick in a year more times than I was ever able to do even trying in my WRX. [0]
[0] - Sure, the WRX is all wheel drive but it's also a good 450 pounds lighter than the Mav.
- detourdog 1y agoThat is also my understanding. I believe the faster one can charge the battery the faster the battery can run the motor.
- detourdog 1y agoThe BMW i3 was the fastest BMW from 0-35 for a while and I don't recall ever chirping the tires. This model was rear wheel drive...
- to11mtm 1y agoProbably a few factors... The i3 is rear wheel drive but it's also rear wheel motor. Bigger skateboard battery means lower center of gravity. But perhaps the biggest factor is RWD the drive wheels don't have to steer (I'd say at least 2/3 of my 'chirps' were starting a turn). I'd be willing to wager the BMW has a better TCS software too. Also I don't run stock tires on my Maverick, I run DriveGuard Plus[1] which are probably less grippy than the standard tires. [1] - FWIW The WRX has 'OG' DriveGuard tires, The Plus supposedly are a -little- more grippy... Only lost 1 or 2 MPG on the Maverick changing to them from stock.
- detourdog 1y agoThe i3 has ridiculously narrow tires. I still memory burn my first experience of BMW TCS from the mid- eighties. My friends Dad got a BMW M5. That car made seemed to just seemed to accelerate.
