the Geec

the Galway Energy Efficient Car

the Geec is a student led project from the University of Galway that designs, builds and races Ireland’s most energy-efficient Car.

The Geec is Ireland’s most energy-efficient car and the only Irish team to compete in Shell Eco-marathon (SEM), the worlds leading ultra efficiency competition. Built by engineering students at the University of Galway, this battery electric eco-car showcases cutting edge student innovation. Since 2015, the Geec has competed annually, pushing the boundaries of energy-efficiency on a global stage.

Some of our proudest moments:

Students from across multiple engineering disciplines come together each year to find new ways of improving the Geec’s performance, and their efforts continue to pay off. Back in 2018, the Geec won the SEM Innovation Award for our unique approach to wheel cover openings, which reduced aerodynamic drag. In 2024, we achieved our best-ever track performance, reaching an incredible 346.2 km/kWh. To put that into context, this means the Geec can travel over 346 km on the same amount of energy it takes to power a 1 kW appliance for just one hour. Most recently, in 2025, the Geec was awarded Best Virtual Garage – the very first year this category was introduced.

Each year students work individually or in groups to ensure the Geec is at its most efficient self. To see some more about this check out our Technical Thread.
