With current battery prices it should be possible, $18,000 in batteries should be able to power a car for 200 miles if they can keep the watt hours per mile down to 250 watt hours per mile and that is possible with batteries that I can buy at bulk prices right now.
That would be around 1,000 pounds of batteries of course.
As it is the 10 cheapest cars in the USA are $12,800 to $15,300, pull the cost of the gasoline parts and a glider might be as cheap as $10,000, leaving around $2,000 for the motor, controller and everything else.
So it would be tight to make a $30,000 car with a 200 mile range, but possible.
