Eco-marathon

The Shell Eco-marathon is a competition for self-built fuel efficient machines, built by students, to travel a set distance using the least amount fuel or electric energy possible. The cars must be powered by petrol/diesel, biofuels (like ethanol and FAME), gas-to-liquid, hydrogen fuel cells or electric batteries.

At the 2013 event, the most successful vehicles travelled nearly 3,000km from one litre of petrol or a single kilowatt-hour of electricity.

The vehicles are designed to be ultra efficient with streamlined shapes and all uneccessary weight removed.
