ET2ev
Its mission: performance.
ET2ev is a tribute to Prof. Emilio Vitale, the strongest supporter of E-Team Squadra Corse and the man who made this happen. ET2ev is the result of two years' experience and thus takes another step forward from the design and performance point of view. ET2ev is expected to show its potential at the next Formula Student Germany and Formula ATA Italy 2009.
