Helsinki Metropolia University

Extremely low power consumption: only 1.6 liter fuel equivalent / in six seconds to 100 km/h / Nokian-saving tire: less rolling resistance good, athletic safety qualities of innovative, fast electric sports car ERA who attends the 2011 e-miglia rally Helsinki Metropolia University of applied sciences in Finland part, the toughest real test for electric cars and the first international E-rally only for electric vehicles from August 1 to 5. Extremely low energy consumed the ERA with only 14.5 kilowatt hours (kWh) per 100 kilometers, representing only 1.6 liter fuel and emits zero CO2. It accelerates to 100 km/h in six seconds, latest 449 HP (330 kW) electric motor technology is its top speed 220 km / h. briefly and 272 PS (200 kW) continuous, pure electric drive with four engines, advanced battery system from lithium-titanate batteries, low-rolling resistance eco tyre Nokian and body in extreme lightweight demonstrate what is technically possible today in practice. Just 3.48 EUR exceed the current cost of the ERA prototypes per 100 kilometres, very little conventional sports car compared to the three best-selling 2011, which cause similar performance each 11.63 euro petrol per 100 kilometers at its average fuel consumption of 7.4 liters per 100 kilometers. The ERA (electric RaceAbout) already won contests: winner of the battery electric rally the Challenge Bibendum in Berlin 2011 with awards for CO2 emissions, emissions, fuel efficiency, design and second prize at the Automotive X-prize 2010, the worldwide competition for the fuel saving car. The range of this electric sports car with 1720 kg unladen weight is initially 200 kilometers. Students of the Metropolia University of applied sciences designed the ERA. When electric cars the tyres consume a substantial part of energy, so the tires are a very crucial part in the development. Electric cars need with extremely low rolling resistance tires, to achieve the greatest possible range.
