Students from the Iron Warriors team at the Lodz University of Technology have developed ultra-efficient prototype vehicles designed to maximize distance per unit of energy. 

The team achieved Polish records using specialized single-person vehicles constructed from carbon fiber to keep weight under 50 kg. The gasoline-powered Eco Arrow 3 model reached 837 km per liter of gasoline, while the electric Eco Arrow 2 Electric model achieved an equivalent of 2,267 km per liter of fuel (or 251 km per kWh). 

To maintain efficiency, the vehicles utilize a teardrop shape to minimize aerodynamic drag and require a driver under 158 cm in height. The project involves over 30 students across various engineering departments and has previously been demonstrated at international venues such as the Le Mans circuit in France.
