Not long ago it appeared in the Lounge of the Motorcar of Frankfurt the Audi e-tron and in these days, in Detroit, one has just showed to the public an evolution of the same one. The mark of the hoops has called it Detroit-Showcar Audi e-tron and his principal innovation is his size, now the Audi concept is smaller than a TT, since it does not reach 4 meters long. One of the stars comes to this blog of the engine from the Lounge of the Motorcar of Detroit, a sports completely electrical one that goes forward to the future.
His bodywork named Audi Space Frame, it is constructed in aluminum, while doors, large door, roof and side panels it are of a very light and resistant synthetic material reinforced with fibre of carbon, the entire weight of the car is located in a few scarce 1.350 kilos. His air earnings have plates capable of improving the aerodynamics of the car, since they close if it is not necessary to refresh the mechanics.
The batteries of lithium, entrusted to feed to two electrical engines, weigh 400 kilograms and go placed in central position I joust ahead of the rear axis, with what the Audi engineers have obtained an excellent weight share-out for a sports one, 40 % of the weight to the front axis and 60 % remaining to the rear axis.
Two electrical propellents produce a maximum joint potency of 204 CV with a high turning moment that is transmitted only to the rear wheels (the original Audi e-tron had four electrical engines, one for every wheel). The new Audi concept incorporates the new technology “Torque Vectoring“, which regulates of independent form the speed of draft of every motive wheel, thanks to it the e-tron obtains a high stability and haulage, helping to the stability control in his task of balancing the car in situations limit.
