Audi has recently revealed their next step into the electric hybrid world with the Audi E-tron prototype. According to Audi, the E-tron is “a realistic glimpse into the future of mobility as Audi is planning it. The electrification of the drivetrain, above all using plug-in technology, plays a deciding role in the strategy of the brand.”

The E-Tron is  a high-performance sports car with a purely electric drive system that is powered by four electric motors rather than a gasoline engine. The maximum output of 313 hp is with overall torque output of 502 lb-ft . The four motors each drive one wheel and can be controlled independently, thus offering torque-vectoring functionality. It I expected to dash from 0 to 60 mph in about 7.5 seconds, top out at 138 mph and go as fast as 81 mph in electric-only mode.

The battery, rated at 53 kWh, takes 2.5 hours to charge with a special 400-volt electrical outlet. Audi claims that a full charge will get you about 150 miles on the road. The battery is charged not only when the car is stationary, but also when it is in motion. This form of energy recovery and return to the battery is already available today in a number of new Audi cars. During braking, the alternator converts the kinetic energy into electrical energy, which it then feeds into the on-board electrical system.

As for the interior, eye- catching and functional references to the new drive concept characterize the interior design. They establish an advanced connection between Audi luxury and new formal characteristics. The cockpit of the E-tron is oriented toward the driver.

Instead of a classic instrument cluster, the concept car is the first Audi to be equipped with a large, fold-out central display with integrated MMI functions. The MMI is controlled via a scroll pad with a touch-sensitive surface on the steering wheel, which is much like modern smartphones. While an analog speedometer on the right provides speed information, the instrument on the left tells the driver how much power is being drawn. The central display shows the range in the status bar and presents all key information from the infotainment and navigation systems. It also provides the driver with relevant data from the vehicle’s communication with its surroundings. The instruments combine the analog and the digital worlds into a single unit.
