If I buy an EV I would like it to do 400 miles, but I don't need 0-60 in 3 seconds.
Low 0-60 times are inherent to EVs. There's no transmission and the motor has a wide efficiency area. It's basically hard to make a non dual motor EV accelerate slowly. Single motor ones aren't quick, but you won't get AWD if that's a thing you desire.
It's easy to make a less powerful motor. As someone else said, the current market is for people who are looking for better performance and aren't concerned with price. I put a deposit on a Polestar 3 that does 0-60 in 4.7s which is slow compared to its competition like the Model X and BMW iX but I don't care about 0-60. It's a meaningless metric to judge a car by. My Challenger SRT 392 does the 0-60 in 4.2s but I bought that car for how nice it looks, not its 0-60.
I think trim packages or settings in the car that trade acceleration for range make a lot of sense.
That's not really how electric motors work though. They spin up crazy fast, which means fast 0-60 times. Think about an electric mixer in your kitchen; it takes more or less the the same amount of time for it get up to speed weather it's on the highest setting or the lowest setting since the motor is the only moving part. There is no fancy gearing to vary the speeds, it's based solely on the amount of energy being put into the system.
Yes, and varying the amount of power put into the system would increase or decrease the total range. A full power launch depletes the battery more quickly than a gentle, controlled acceleration to road speed.
I'm talking about limiting the amount of power that can be dumped into the motor at any given time, or limiting the power of the motor itself in order to get a more efficient experience.
That's entirely on the user at that point, and cant really be designed around. Anything you add to limit acceleration is just going to add more complexity and expense for no actual benefit. If you want better range, stop flooring the car out of every stop, same as an ICE car.
Ye canna change the laws of physics! Acceleration is proportional to force exerted (F=ma) and has nothing to do with the amount of energy stored, which gives you range. You might get a few percent efficiency bonus from lesser acceleration due to losses (so 2-3 extra Km per 100), but you can't "trade acceleration for range"
