For a first attempt at a (simulated) EV the Project-E is quite decent. And I get the fact that, upon closer examination it actually has a very powerful petrol engine, in keeping with the company’s heritage - so I’m assuming that the same car will be offered with petrol and electric drivetrains.
However, I’ve taken a look at all the cars you’ve offered us, and on closer inspection, you clearly still have a few lessons to learn:
Avoid +15 quality slider spam at all costs. Even if used on just one slider, pushing the quality all the way to its maximum will increase PU and ET beyond realistically feasible levels. Try using positive quality in moderation instead.
Some of your cars don’t have a catalytic converter - a big no-no considering that this item is mandatory for all modern cars. Speaking of the modern era, in these emissions-conscious times, a three-way converter (either regular or high-flow) is the way to go.
Race intakes and exhaust systems are for race cars, not road cars. Those should use either standard or performance intakes, and not be fitted race headers or straight exhaust systems (i.e. no mufflers).
And I understand why the Proto-X Unlimited is so fast… It uses an OP (as in overpowered) body mod (specifically, the EV1 body) that has so little drag, it has no trouble reaching such immense speeds!
