Mileage Challenge
In the first of our 2 semi-finals, The Bodgers (who defeated the Navy Blues in an amphibious vehicle challenge) will face In A Spin (who crushed the Braniy Bunch's glider). The challenge is to buils the most fuel efficient vehicle. They'll test them on an oval track. Who ever travels the farthest, wins. The "car" must carry one person who must switch off with another teammate after 4 laps. The final teammate stays on intil they are out of gas. They'll have 1/2 pint (382mL) of fuel TOTAL to burn.

Not much "science" to this one. Lighter is good. They'll need small engines, thin wheels (to reduce friction) and light a chassis. They'll also want to reduce the physical size as much as possible to reduce air resistance. Also, to shed weight, all essential systems will need to be minimalized (steering, brakes, drivetrain, etc) to keep the weight down as well.
