The competition dates back to 1939 when Shell Oil Company employees in the USA made a friendly wager over who could travel furthest on the same amount of fuel. Since then it has expanded to two more continents, includes many energy types and sparks passionate debate around the future of energy and mobility.
The competition is split into two classes or categories. The Prototype class focuses on maximum efficiency, while passenger comfort takes a back seat. The UrbanConcept class encourages more practical designs. Cars are also divided by energy type:
- Internal combustion engine fuels include petrol, diesel, liquid fuel made from natural gas and ethanol.
- In the electric mobility category, vehicles are powered by hydrogen fuel cells and lithium-based batteries.
Chalmers competed in the UrbanConcept class.
