UP - December 07, 2009. At the Los Angeles Auto Show the German manufacturer Audi satisfied the visitors with two spectacular presentations: The R8 Spyder stroke spectators with impressive visiual effects and remarkable performance details. On the other hand one of the stars with the most audience appeal was the new Audi sports car "e-tron". This hightech two-seater will be on sale in 2012 as a limited edition of 1,000 cars. It has four electric motors powered by lithium-ion-batteries and goes pure electric.
