The Shell Eco-marathon is an international competition focused on special vehicles with extremely low fuel consumption. The Faculty of Mechanical Engineering TUKE has been participating in this competition for more than 25 years. In said time, our students designed and built 8 racing cars. The development of each of them presented a great challenge. In order for 7the vehicle to travel as far as possible with a single litre of fuel, it must have a low aerodynamic and rolling resistance, low weight and at the same time meet strict safety requirements. In the last year, our team managed to drive 824.84 km on 1 litre of fuel, which is not only our personal, but also an absolute Slovak record.
