With the prototype e-tron Sportback Concept, Audi unveils some design features and technical solutions that will have a production model to be launched in 2019. Share the drive system with the e-tron quattro concept , another prototype that Audi introduced in 2015 and is distinguished mainly by the design of the body.
It has four doors and measures 4.90 meters in length, that is, has a size similar to a BMW X6 or a Mercedes-Benz GLE Coupé . An Audi Q7 is a little longer and also the fall of the end of the roof is not as pronounced.
It moves thanks to three electric motors, one of them located in the front axle and the other two in the rear. They give a maximum continuous power of 435 hp, although temporarily (activating the “Boost” mode) reaches 503 hp and 800 Nm of torque. According to Audi, the latter configuration accelerates from 0 to 100 km / h in 4.5 seconds (0.1 seconds less than the e-tron quattro concept) and reaches a limited maximum speed of 210 km / h.
The battery is located under the floor of the passenger compartment, is lithium ion, has 95 kWh and allows a range of “more than 500 km”. The main method of recharging is through its connection to the electric grid and supports both alternating and continuous current. Of this last way and in a take of 150 kW, it needs 30 minutes so that the load is enough to cover 400 km. It is also possible to recover energy during braking (although with less intensity). Optionally, Audi offers a wireless charging system.
The suspension is independent in the two axles, has pneumatic springs with variable hardness adjustment and four predefined height positions (with 63 mm difference between them). The tires are measures 285/30 and are mounted on alloy wheels 23 inches in diameter. The brake discs are 508 mm in diameter on the front axle and 483 mm in the rear.
In the cockpit there are several TFT and OLED (organic light emitting diode) displays: one that acts as instrument cluster (Virtual Cockpit), two in the console (the top is 25.4 inches) and one in the Panels of each of the four doors. The multimedia system has connectivity through a 4G module. This prototype has no conventional rearview mirrors, but two cameras that project the images captured on two screens intended for this purpose.
The headlights of the e-tron Sportback Concept combine LEDs with laser projectors, a system that Audi calls “Digital Matrix Led” and allows to illuminate different areas with more precision than Matrix Led. They are also capable of forming warning signs on the road (for example, a signal or a pedestrian crossing).
