2,843.4.
That’s a big number. In dollars, in water bottles (more on that later), but especially in MILEAGE!
From MSN:
A group of students from Mater Dei HS in Evansville, IN competed in the 2008 Shell Eco-marathon Americas - and drove away with a new record for a vehicle than can get 2,843 mpg! Our two SUV’s can get maybe 20-25.
