Audi e-tron Sportback Concept - Interior, Exterior and Features.
The Audi e-tron Sportback represents an important milepost for Audi along the road to electric mobility. Rupert Stadler, Chairman of the Board of Management of AUDI AG, confirmed: “Our Audi e-tron will be starting out in 2018 – the first electric car in its competitive field that is fit for everyday use. With a range of over 500 kilometers (310.7 miles) and the special electric driving experience, we will make this sporty SUV the must-have product of the next decade. Following close on its heels, in 2019, comes the production version of the Audi e-tron Sportback – an emotional coupé version that is thrillingly identifiable as an electric car at the very first glance.”
The concept car’s lighting technology is an innovation that is visible by both day and night. Digitally controlled Matrix LED units at the front and rear produce an excellent light yield. Minuscule Digital Matrix projectors literally make their mark on the road ahead, turning light into a versatile, dynamic channel of communication with the surroundings.
For its drive, the e-tron Sportback uses a configuration that will also be adopted in future production Audi models with all-electric drive: One electric motor on the front axle and two on the rear power all four wheels, transforming the high-performance coupé into a quattro in typical Audi style.
320 kilowatts of power – which can even reach 370 kW in the boost mode – provide a fitting level of propulsion, with the sprint from 0 to 100 km/h (62.1 mph) a done deal in just 4.5 seconds. With the battery’s energy content of 95 kilowatt-hours, its range is in excess of 500 kilometers (310.7 miles) (NEDC).
Dr. Dietmar Voggenreiter, Member of the Board of Management for Marketing and Sales at AUDI AG, understands the special significance of electric mobility for the market in China: “We have made a conscious decision to give the Audi e-tron Sportback its first showing here in Shanghai, because China is the world’s leading market for electric automobiles. That applies as much to the infrastructure and financial support as it does to sales. There are already about 150,000 charging stations in the country, with another 100,000 due to come on stream by the end of 2017. We are well equipped for this rapid growth. In the next five years we will be offering five e-tron models in China, including purely battery-powered vehicles with ranges well in excess of 500 kilometers (310.7 miles) such as the Audi e-tron Sportback.”
The Audi e-tron Sportback concept technology study uses three powerful electric motors – one on the front axle and two on the rear axle. Total output is 320 kW, with boosting enabling the driver to temporarily mobilize up to 370 kW.
The electric motors are highly efficient over a wide engine speed range, including at low and intermediate load. They thus combine emotional driving pleasure above all with a high range. The electric motors are liquid-cooled, as are the compact power electronics.
The brand first showcased the concept for the three electric motors in its Audi e-tron quattro concept study car at the 2015 Frankfurt Motor Show. It will now find use in future production versions. And it turns the Audi e-tron Sportback concept into an electrified quattro, because torque is delivered to all four wheels.
The operating principle is as follows. A controller continuously computes the optimal interplay of the electric motors for every driving situation. At low load, solely the motor on the front axle is responsible for propulsion. When the driver floors the accelerator in the S driving mode and all three electric motors are working together, 370 kW of output and more than 800 Nm (590.0 lb ft) of torque are available in the boost mode. The sprint from zero to 100 km/h (62.1 mph) is completed in 4.5 seconds; the electronically limited top speed of 210 km/h (130.5 mph) is quickly reached. In the standard D driving program, the e-tron Sportback musters 320 kW.
The key drive train management parameters are the position of the accelerator, the mode chosen in the Audi drive select dynamic handling system, the driving program – S or D – and the battery charge level. The data on the near surroundings from the sensors for piloted driving, the predictive route data from the navigation system and the real-time traffic information from Audi connect also flow into this computation, always with the aim of optimally adjusting the drive train to the prevailing conditions.
