It still costs money. More asphalt, more padding = more cost, more labor to put it in. If you don't have to put it in, that saves you money to keep up with the luxury models, which was my only point.
Roughly speaking, when you go to make an EV, you want an efficient motor to better conserve battery power. A more efficient motor can also be used as a more efficient generator when you're doing regenerative braking. One thing about electric motors is that larger, more powerful ones are also more efficient. So when you use a very efficient motor you end up with power levels that can run a luxury performance vehicle.
Now consider long range - batteries are not only limited by the amount of energy they contain, but the amount of power they can provide(IE energy over time). Longer range = more batteries, which also equals more power - indeed, more than enough to run that bigger, more efficient and powerful electric motor at it's full potential. So we're back to luxury performance vehicle levels of power.
As an aside, back in the day auto companies that make hybrids did a lot of research into increasing the power capacity of their batteries so they could put a smaller, shorter ranged battery in. Regenerative braking was seriously limited by the power absorption capabilities of the battery. With a long range EV? Not so much.
