Car #114 Tecnun eRacing

Info

Tecnun eRaicng is a 70 member team from Tecnun-Uniersity of Navarra, uniting students from multiple engineering degrees. Born from the combustion team Tecnun Motorsport (2009), the electric team was created in 2012. Since then, we have never stopped improving, achieving 1st Efficiency and 2nd Overall at FSS with TeR24. In 2025 we reached new milestones: FSA debut and FSG comeback. With TeR26, our first Driverless car is born. Next goal: the first 4WD with TeR27. We'll keep learning and growing!
