Audi e-tron quattro concept is going to be one of the main attractions at the International Motor Show (IAA) 2015 in Frankfurt in September. Since there is less than a month until the premiere, Audi has released the first official sketches of the all-electric sporty SUV. Five images give us a very good idea of what we are to expect from brand's first large-series electric car.

The e-tron quattro concept is a pioneer in its segment. It has been designed from the ground up as an electric car, thus being the first such vehicle in its segment. The visual appearance of the model is built around the design of Audi "Aerosthetics" concept.

The images also show a typical design for the brand with the characteristic SUV body and the flat, coupe-like but spacious cabin.

This means that it combines technical improvements, which reduce the aerodynamic drag and at the same time are so creative that they also appear as design solutions. For instance, there are movable aerodynamic elements at the front, while on the sides and at the rear the specialists at Audi have enhanced the air flow around the car. Moreover, the aerodynamically optimized underbody is entirely closed.

The Battery

This electric SUV has a cd value of 0.25. This in turn considerably contributes to the range of more than 500 kilometers (310 miles), which beats even Tesla Model S. The large lithium-ion battery is mounted between the axles and below the passenger compartment. This installation allows for low center of gravity, balanced axle load distribution, and better driving dynamics.

What was also understood from Audi is that the length of the e-tron quattro concept is positioned between the Q5 and Q7 models and it is based on the second-generation modular longitudinal platform.

At last, we should also say that the Audi R8 e-tron sports car served as an inspiration for this concept. In fact, the drive system in the SUV is the same as in the sports car. There are exactly three electric motors used in both vehicles: one on the front axle and two on the rear axle, and they are driving the concept.

Oh, and what is even better is that the sporty SUV with top aerodynamics and all-electric drive is scheduled for a series production in 2018.
