The tires are eighty percent wider!

11.9% heavier
36.5% less aerodynamic

What are the rules of thumb? Is fuel economy proportional to half the change in mass or cD? If so, before the drivetrain changes everything, just the body decreases MPG by 25% (25.28%), so from 250 to 90.

How much efficiency do you lose when going from a 12.6-second 0-60 to 0-62 in 5.7 seconds? Isn't it from 47 HP to 199?

Honestly, it should still get good mileage, but they complained that the XL1 cost $120,000.

What would be the price for this?!
