Take this with a grain of salt, but it might not be in their best interest to move to the lower end market.
If they can make a cheap EV car then so can another producer somewhere else in the world.
Just recently I read Ferrari actually dropped the number of cars they produced per year.
Why did they do that? The wanted to make their cars more exclusive by making it harder to buy a Ferrari, increasing the length of the waiting list and allowing them to charge more for the car.
Strange things seem to happen at the top end of the market.
