One electric motor drives the front axle, the two others act on the rear axle for a total output of 320 kW. The driver can even mobilise 370 kW and over 800 Nm (590.0 lb-ft) of torque temporarily while boosting. The concept study thus performs like a sports car. When the driver floors the right pedal, the Audi e-tron quattro concept sprints from a standstill to 100 km/h (62.1 mph) in 4.6 seconds and quickly reaches the electronically governed top speed of 210 km/h (130.5 mph).
An intelligent drive management system controls the interplay between them as appropriate for the situation. The focus here is on the greatest possible efficiency. The driver decides on the degree of recuperation, the driving program S or D and the mode of the Audi drive select system.
During sporty driving on a winding road, the Torque Control Manager actively distributes the power between the rear wheels as necessary. This torque vectoring provides for maximum dynamics and stability.
The large lithium-ion battery is integrated into the floor of the passenger compartment in order to give the Audi e-tron quattro concept a balanced load distribution and a low centre of gravity – to guarantee dynamic handling. The battery’s capacity of 95 kWh enables a range of more than 500 kilometres (310.7 miles). A full charge with DC electrical current at a charging column with an output of 150 kW takes just around 50 minutes. As an alternative, the study is equipped with Audi Wireless Charging technology for contactless and convenient induction charging.
The Audi e-tron quattro concept uses a system for piloted parking that guides it to the proper position at the charging plate. In addition, a large solar roof provides electricity for the drive system battery on sunny days.
The dynamic all-wheel steering combines a dynamic steering system on the front axle with a steering system for the rear wheels. Depending on speed and the driving situation, they steer either in the opposite or same direction as the front wheels. The Audi e-tron quattro concept thus reacts even more stably and is also very manoeuvrable at low speeds.
The Audi e-tron quattro concept harmoniously combines the design with the aerodynamics and all-electric drive system. The five-door technology study is 4.88 metres (16.0 ft) long, 1.93 metres (6.3 ft) wide and just 1.54 metres (5.1 ft) high. Its coupé-like silhouette with the extremely flat greenhouse that tapers strongly toward the rear lends it a very dynamic appearance.
All of this contributes considerably to the long range of more than 500 kilometres (310.7 miles). Wind noise is low inside the car, and there are no engine noises in an electric car in any case. The fascination of electric driving unfolds in near total silence.
The vertical separating edges on the side panels and the fully enclosed floor pan with its newly designed microstructures contribute to reducing drag. Cameras replace the exterior mirrors – another contribution to the excellent aerodynamics and also a foretaste of the future of driving.
All the main lighting functions at the front of the car use Matrix laser technology. The bottom section houses a new, distinctive lighting signature comprising five lighting elements. Each of these combines an LED luminary with an extremely flat OLED element (organic light-emitting diode).
The package of the Audi e-tron quattro concept enables a spacious, comfortable interior for four persons and 615 litres (21.7 cu ft) of luggage. The interior has a light and open feel to it; its architecture melds harmoniously with the operating and display concept. All displays in the interior use OLED technology.
The new Audi virtual cockpit curved OLED is a further development of the Audi virtual cockpit. The driver controls the lights and the systems for piloted driving with the left display. The large display on the right is for media and navigation management. The steering wheel serves as an alternate control level.
Two more OLED displays offer information about the drive system status, climate control and freely programmable information functions. The curved displays in the front section of the doors serve as digital exterior mirrors.
The two rear passengers can use the OLED displays on the centre console to configure the climate control and infotainment for their area or to exchange data with the driver. An LTE module connects the Audi e-tron quattro concept with the Internet. The connectivity features in the study are cutting edge.
The concept study is equipped with all the technologies that Audi has developed for piloted driving: radar sensors, a video camera, ultrasonic sensors and a laser scanner. The sensors collect data that is gathered in the central driver assistance controller (zFAS) in the luggage compartment. It computes a complete model of the car’s surroundings in real time and makes this information available to all assistance systems and the systems for piloted driving. These technologies are also nearly ready for use in production vehicles.
The time has come for sustainable mobility. Audi’s alternative drive solutions promise an exciting future without compromises. e-tron is powered by electricity – and charged with excitement.
