There are no survivors in the EV market from 10 years ago but Tesla.
Sure, and none of the other auto manufacturers had made any serious efforts to produce a competitive EV 10 years ago. That's not the case now, which is why I asked which of the current crop of EV's from marques other than Tesla you've had some experience with.
While there have been some (considerable) bumps along the way, most of them have brought, or are bringing, competitive EV's into the market now.
BMW got handed their hat to eat on the i3 and i8.
The i3 was never a Tesla competitor, the i4 is. The i8 wasn't an EV and was also extremely expensive.
Audi is muddling along but wasn't good enough for you to keep.
And I couldn't bring myself to buy a Tesla (I was considering a Model Y Performance), based on the materials selection, road noise and general lack of appointments. At least the Audi was properly equipped in that respect, but my wife found it too quiet, and it drove her nuts, so we got rid of it.
No one makes the equal of Tesla's drive units, batteries, or the Supercharger network.
Except the Supercharger network is now being opened up to other brands. Tesla doesn't have a monopoly on good drive units, and the i4 M50 is faster than the 3 Performance from a roll. Tesla has changed battery styles several times now (even using prismatic cells in some variants, which is what BMW uses in the i4) and on the most recent models, not only are they fully potted, but they are structural to the car, IE, not designed to be replaced, while their competition has made their batteries modular and serviceable so you can swap out individual cell modules for example. Tesla's approach is very "iPhone", they want you to just buy a new car.
Tesla deserves to be dinged for poor suspension tuning.
Amusingly, that was far from my biggest complaint about the S and 3 that I drove. I still owned my M5 when I test drove a physician friend's S and was quite underwhelmed at the interior compared to the bimmer, as both cars targeted roughly the same price point.
The 3 (which my client friend owns and loves), I couldn't get over the road noise and interior materials. Yeah, the suspension tuning wasn't great, but it was the cheap feeling interior and lack of a HUD which really turned me off. The i4 is a much better car in this respect (he has not driven the i4).
Despite Ford's issues with the Mach-E, it's a really nice EV in its own right (and I have considerably more than 30 minutes of seat time in one of these, as we seriously considered buying one and had it for a few days, using it as a DD). It drives very well, the interior doesn't feel "Dollar General", road noise is low...etc.
Tesla still has an advantage in BMS programming I suspect. They have considerable data by way of telemetry that has allowed them to fine-tune that, but other marques will catch-up as they amass similar data.
The EV space is a moving target and as Tesla's competitors field their offerings, it's good for everyone, as competition drives innovation and forces everyone to up their game. Maybe we'll even see real leather and a HUD from Tesla at some point
