Comments Off on Hungary’s Kecskemét College: Boosting Power, But Keeping Light

Hungary’s Kecskemét College had an amazing second-place run in last year’s Shell Eco-marathon Europe, and the team was determined to kick up its performance this year. The gasoline-powered engine is now 45 cubic centimeters, about a third larger than last year’s engine for the car, nicknamed Megameter, which achieved a performance of 2,695.5 kilometers per liter…

What if you could pack and assemble a car like Ikea furniture? Students at Aston University aimed for lightweight portability and sustainability in the wood car they designed and built for Shell Eco-marathon Europe. Their project manager, Christian Mclening, explains the innovative plywood composite chassis and “flat-pack” design in the video below. In addition to…

Dana and Lorena Ruisi of Universidad Cardenal Herrera’s Idea Ceu Team from Spain explain that their team took inspiration from nature for the shape of their car entered in Shell Eco-marathon Europe. Their vehicle is shaped like a rain drop. They believe falling rain is one of nature’s most efficient means of movement, and they…

As a college athlete (track and field), I understand the desire to put on a good performance while on one’s home turf.
