Algebra on the numbers. 40k, 50k and 70k. 250, 300 and 500 miles. 1, 2 and 3 motor. Assuming costs and price are somewhat linear. Tesla can of course charge some random number. I suppose anyone can make a guess or have an opinion. I just did the math.
Or just do the math and arrive at $6666 for one motor and $3333 for 50 miles of range.
39900 + 6666 + 3333 = 49900
39900 + 2x6666 + 5x3333 = 69900
Adding $6666 to the C3 70k is probably not correct, given what we don't know.
