H-TU 11

Our vehicle for the season of 2011

The development of the first vehicle – which was named “H-TU 11” – of the TUfast e.V. Eco Team lasted about 2 years. It was finished on time for the Shell Eco-marathon 2011 at the Lausitzring. This gave us good experience for the development of future vehicles.
