This is a possible mass production of electric supercar, but with the traditional internal combustion engine supercar driving experience in the performance and the gap has been narrowing. R8e-tron not only heralded the birth of the future direction of development of ultra-running, but also for the mass production of electric cars Audi has accumulated rich experience and technology.
Intrinsic big difference
Audi R8e-tron body with petrol version only nine shared parts and audi geko diagnosic software, Audi R8e-tron support vas 5054a windows 7. because there is no oil cooler and does not require the intake, so the side air intakes and wings are made of seal design, the cooling air through the lower single-frame grille only enter , intelligent thermal management system for cooling. With gasoline version is different, R8e-tron is not only not set spoiler and exhaust pipes, windows have been replaced by the end of opaque black material, completely reversing
Dependent rear HD camera.
R8e-tron no internal combustion engines, transmissions and exhaust systems, so more smooth underbody, the drag coefficient of only 0.27. Thanks to a large number of carbon fiber material and the use of aluminum body frame, even after loading a large number of cell components, R8e-tron's weight was controlled at 1780 kg, only petrol version R8Coupe heavier than 15 kg.
Driving pleasure diminished
Despite fewer large displacement super-race that makes blood ruin sheets of noise, R8e-tron power performance and sport-tuned chassis, but did not lose petrol version R8. High-power electric motor power output is very linear, just 4.2 seconds to speed Pobai. R8e-tron's two electric motors on the rear axle torque vectoring can be achieved in fast cornering, torque distribution according to needs of targeted braking to individual wheels or accelerated, which also makes R8e-tron in a continuous curved Road still manipulating flexible and rapid response.
Even if the mileage of 215 kilometers, a rechargeable electric car is still troubled by the problem. R8e-tron although you can be charged from a household AC power, but a full charge takes approximately 12 hours, if the pile through a dedicated DC charging, charging time can be shortened to one hour. To improve security, Audi R8e-tron is also equipped with a unique e-sound synthesis sound system, at speeds below 60 km, the computer will calculate based on the data and through the vehicle audio frequency speaker to play the road to warn passers-by.
