The Galway energy-efficient car
The Galway energy-efficient car, the Geec, is an eco-car designed and built by NUI Galway engineering students. Every year since 2015, we compete inthe Shell Eco-marathon Europe, a 16-km street-circuit race where the winner is the car that uses the least fuel or energy.
In 2017 we finished 13th of 41 competitors in the prototype battery-electric class, with a score of 354 km per kilowatt-hour of electricity – roughly equivalent to 10,500 miles per gallon for a diesel car. Then we went on to win the 2018 Technical Innovation Award. The Geec is the first and only Irish team in the world’s top ultra-efficiency competition, and the most energy-efficient car ever built in Ireland.
The car’s structure is composed of a carbon-fibre composite aerodynamic body, over an aluminium chassis. Power is provided from a lithium polymer battery to a 200-Watt DC motor, driving the rear wheel through a gear pair and a chain drive.
