TUfast eLi14 is a small aerodinamic tear-drop shaped electric car, developed by a team of students from Technical Univesity of Munich for 2014 Shell Eco Marathon. It wasn't the best then but later the team made extensive modifications, like upgrading the engine with a custom controller, silver wire coils and custom wheels with ultra-low friction bearings.

Finally they took it to the Audi's test facility and recorded a record braking efficiency run with 1143 km/kWh. On the second run they improved the record again and drove 1232 kilometers with 1 kWh. In petrol terms, that means that TUfast eLi14 could run more than 11.000 on one litre of fuel.
