The Shell Eco-Marathon is sort of a weird contradiction. On the one hand, it's sponsored by Shell, but on the other hand, it's all about challenging high school and college students to make hyper-fuel-efficient cars, i.e. kind of the opposite of Shell's goals. It's like if the Intel high school science competition were sponsored by Rick Santorum.
At any rate, though, the kids really came through this year. Here are four of the winning vehicles, all built by high schoolers, all of which got more than 1,000 miles to the gallon in their competition trials.
