The post from earlier about getting smoked by a Volt got me thinking. My commute is only 8 city miles, so range anxiety isn’t an issue. Plus I can plug in at work since I own the place.
So the questions is: Are these EVs, like the Volt, designed to be driven hard all of the time if you don’t care about range? Or will that wreck the batteries and motor?

I am fairly certain the computer that controls the batteries will prevent them from being killed.
It will wear them out sooner though. But I doubt the batteries would need replaced in a year or something like that.

Yeah man that thing was quick this morning. Really got me thinking too. An inexpensive RWD EV could be awesome. My guess is that there are so few moving parts that it wouldn’t matter? Unless the motors are poorly designed

From my admittedly limited understanding of battery electronics, you’re going to cycle the battery faster, which could have an impact on life...but I don’t think that means you’ll wreck it.
Similarly, electric motors have fewer moving parts and are designed to spin faster than most ICEs, so the wear on the actual powerplant is probably significantly less than in a gas car.

The ECU will not let you kill it too much.. There is a reason a Tesla Model S can’t repeat it’s fastest launch more than twice before cooling off.
Also the batteries won’t last as long like other people pointed out.

If a li-ion battery pack is charged or discharged too quickly it can cause battery degradation that can significantly hurt the lifetime of the battery pack. Because of that, there are calibrations in the Volt (and other electric/hybrid vehicles) that prevent that from happening by limiting the battery current. Battery degradation is also why the battery pack is never actually discharged all the way to zero or fully charged to 100% like your phone does, as limiting it also increases the lifetime of the battery. Typically a “full charge” is about 80-90% of the battery pack’s actual full and an “empty” battery is typically about 20% state of charge (SOC). Now, with all that said, it is possible to remove those safeguards in the calibrations and have yourself a rather quick Volt (as some have done), but at the cost of a severe reduction in how long the battery can hold a charge and it’s lifetime.

TLDR: Yes, you’ll be fine. The car is limited to prevent that from happening.

You would probably have to replace the batteries in 6-8 years instead of 10. Other than that you should be fine. The motor will run forever if they didn’t fail at cooling it.

So basically the car will protect itself unless you modify it. Interestingly, it’s about the same as an ICE. Most are fairly under-stressed so that they last longer (in the case of my truck, GM wants it to last at least 100k miles, otherwise the repairs are on their dime). But I could probably get 500-600 HP out of that motor if I really tried, at the cost of a shorter lifespan.

It’s really piquing my interest. Pick up a used ELR and beat everything off the line. The max speed limit on my commute is 35 mph so no one would ever catch me (without attracting unwanted attention).

That’s exactly right. Those safeguards make the battery pack more robust and can be cycled (charged -> discharged) more often than your phone can, since electronics’ lifespans are typically shorter than cars’.

Yup,
I drive a 500 E and i do just that.. I thrash the living crap out of it.
I got 10k miles on it and i think i need new tires but i enjoy it a lot. Its small and regardless of what some might say about it loosing battery over time if i keep doing it I don’t really care cause its a lease and to be honest i have not lost any miles in the last year i have used it. DO It. get a lease around March as they are the cheapest at the time in CA. I pay $83 for mine a month with $0 down.
