As a supplier or aftermarket provider, you can obtain some of the specs of what the OEM still considers safe. Especially, if the same engine or component is used in another series production vehicle to higher specs. Like that e-motor in the i3.
The American aftermarket industry has been living off this fact for decades. That's how you can easily buy a Chevrolet crate motor with 572 ci (based on a stock 454) that puts out 1000 hp. All warranties are off at that point, of course. ;-)

I've had two GMC dually trucks with that 454 cid engine (to pull horse trailers). They generated barely 260 HP and something pathetic like 300 lb ft of torque. I know there's been a lot of progress since then, though. And those engines were seriously understressed.
