Audi R8 e-Tron Concept 2009

In September 2009, at the Frankfurt motor show, Audi has taken the wraps off concept electric supercar e-tron, built based on the R8 model.

This novelty has got four electric engines (two on each axis), the total output is 313 horsepower and maximum torque is 4500 Nm. The vehicle is also equipped with lithium-ion batteries, providing the vehicle movement of over 248 kilometers. According to Audi, the supercar concept can accelerate from zero to a hundred kilometers per hour in 4.8 seconds and from 60 to 120 kilometers per hour for 4,1 seconds. Due to the fact that with the growth of speed rate increases also the energy consumption for e-tron limited at around 200 kilometers per hour.

From common household electrical socket with a voltage of 230 volts the batteries are fully charged in six to eight hours, while on the move energy reserve in the batteries will be recharged through a system of energy recovery during braking.

In addition, the novelty has powerful brakes with ceramic discs. On the front axle of the vehicle there is a Hydraulic, and at the back an electromechanical floating calipers, which are activated without a mechanical or hydraulic impact, but only with the help of an electric signal. According to the Audi company, this system allows you to remove the residual losses due to arising friction when the brake pedal is released.

Audi e-tron is also equipped with a communication system Car-to-X, which allows the cars to communicate with each other. It can warn the driver of an emergency on the road ahead, find yourself a free parking space at the entrance to the shopping center, with the help of the navigation system to pave the route in such a way as to reduce energy consumption, as well as inform about the origin of traffic jams ahead.

We’d like to note that the company Audi has reported that currently the plan of the production line of electric vehicles is approved. In the range of the future mass-produced of electric vehicles will be a supercar, a roadster and a compact city car built on the basis of the concept car Volkswagen Up!
