The Audi E-Tron Concept is an electric car concept has been shown in Frankfurt. The Audi E-tron Concept has all the drivability of a go-kart – agile, good on bends and neutral right up to the very high handling limit. The drive system, power electronics and battery have innovative thermal management – crucial for maintaining a high operating range coupled with outstanding interior comfort.
This electric car with Lithium-ion batteries, located for an optimal center of gravity behind the passenger compartment and ahead of the rear axle, make an effective energy content of 45 kilowatt-hours available. This makes an operating range of up to 250 kilometers (155.34 miles) realistically possible. The charging time when the battery is empty is around 11 hours, but heavy current (400 volts, 32 amperes) cuts this to around just two hours. The battery is charged not only when the car is stationary, but also when it is in motion. During braking, the alternator converts the kinetic energy into electrical energy, which it then feeds into the on-board electrical system.
The Detroit Audi E-Tron Concept is 3.93 meter (154.72 in) long and 1.78 meter (70.08 in) wide but just 1.22 meter (48.03 in) tall two-seater. Interior that carries the visual and functional style are the hallmarks of an Audi. Typical for the Audi design idiom is the reduction of the architecture, controls and information output to the essentials in favor of visible lightweight construction and a tidy overall impression.
Energy supply system need two asynchronous electric motors with a total output of 150 kilowatts (204 hp) give the Detroit Audi E-Tron Concept the performance of a genuine sports car. The concept car can accelerate from 0 to 100 km/h (0 – 62.14 mph) in 5.9 seconds if necessary, and goes from 60 to 120 km/h (37.28 – 74.56 mph) in 5.1 seconds. While speed is achieved at the top speed is limited to 200 km/h (124.27 mph), as the amount of energy required by the electric motors increases disproportionately to speed. The range in the NECD combined cycle is approximately 250 kilometers (155.34 miles).
