It is almost impossible to compare the new Audi PB18 e-tron and the R8 V-10 Plus. While taking the shape of supercars, the Audi R8 V-10 Plus and the new Audi PB18 e-tron are different on so many levels I find it rather amusing to see where Audi is going with its e-tron and sports car program. Nevertheless, revealing the Audi PB18 e-tron at the Monterey Car Week, Audi held a long said promise of developing a super fast electric supercar. I will go one step further here and say that PB18 e-tron, if it ever reaches production heaven, will be a supercar at the very least. Currently, Audi provides a whole set of sports machines from the S and the RS line of cars. Yet, the only one to even touch the majesty of the PB18 e-tron is the Audi R8 V-10 Plus. Of course, only the most powerful version as the PB18 is plainly mad.
