School: National Technical University of Athens (Greece)

Team: Prometheus

Car Name: Pyrforos (Battery Electric Prototype category)

What is special about your car? The main innovative component of the "Pyrforos" vehicle is its powertrain and especially its propulsion system, which combines state of the art technology with all the experience gained through our team's participation in the previous years' competitions. The propulsion system of the vehicle comprises an in-wheel permanent magnet (PM) motor placed in the back wheel, which directly drives the vehicle and as a result no additional transmission system is required. The final motor efficiency under racing conditions is over 90%, which is outstanding for such a low power application.

Why is fuel efficiency important to your team? Fuel efficiency is the main technical goal that we want to achieve by designing innovative and efficient electrical and electronic systems that are integrated into our vehicle. Fuel efficiency is of paramount importance for our team, as by this way we can save not only energy resources, but also money.

Who or what inspired you on the way to Eco-marathon? On the way to Eco-marathon we were inspired by the main purpose of this competition which is to design an energy efficient vehicle. The fuel efficiency is a vital issue for humanity and by participating in this competition, we were able to exchange our ideas, thoughts, knowledge in order to create and learn. For our way of thinking, students all over the world should "fight" altogether against the threat of the lack of the natural energy resources.
