Aerodynamically optimized design with a drag coefficient of 0.25, a powerful, purely electric e-tron quattro drivetrain with up to 370 kW of power output and a range of around 500 kilometers (310.7 mi) – Audi is presenting the Audi e-tron quattro concept at the CES and, in turn, is making a statement about the future of electric mobility: It is sporty, efficient and suitable for everyday use.
Electric power: up to 370 kW of power output
The Audi e-tron quattro concept uses the power of three electric motors: One electric motor drives the front axle, the two others act on the rear axle. Together they produce 320 kW. During boosting, the driver can even draw temporarily on 370 kW and more than 800 Nm (590.0 lb‑ft) of torque. The concept study offers sports car-like performance. 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).
The concept with three electric motors which Audi is presenting for the first time makes the technology study an e-tron quattro. An intelligent drive management system controls the interplay between them as appropriate for the situation, while also maximizing 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.
95 kWh of energy: the lithium-ion battery
The large lithium-ion battery is integrated into the floor of the passenger compartment. It gives the Audi e-tron quattro concept a balanced axle load distribution and a low center of gravity – prerequisites for its dynamic handling. The battery’s capacity of 95 kWh enables a range of more than 500 kilometers (310.7 mi). The Combined Charging System (CCS) enables charging with DC or AC electrical current. Half an hour charging at a 150 kWh rapid charging column provides the driver with a range of over 400 km (248.5 mi).
The study is also designed for use with Audi Wireless Charging technology for contactless inductive charging. The charging process is very convenient.
The Audi e-tron quattro concept uses a system for piloted parking that guides it automatically to the proper position above the inductive charging plate. When the sun is shining, a large solar roof also provides electricity for the drive system battery. A heat pump climatizes the interior in a highly efficient way. It uses the waste heat from the electrical components and is a core component of the thermal management system.
The chassis also expresses the high-tech character of the concept study. The adaptive air suspension sport, which features controlled damping, lowers the body at higher speeds and thus reduces drag. The dynamic all-wheel steering combines a dynamic steering system on the front axle with a steering system for the rear wheels. Depending on the speed and driving situation, they steer either opposite or in the same direction as the front wheels – the Audi e-tron quattro concept thus reacts even more spontaneously and stably, and is also very maneuverable at low speeds.
Top aerodynamics: the exterior design
The Audi e-tron quattro concept harmoniously combines the design with aerodynamics and the all-electric drivetrain. The five-door technology study is 4.88 meters (16.0 ft) long, 1.93 meters (6.3 ft) wide and just 1.54 meters (5.1 ft) high. Its coupe-like silhouette with the extremely flat greenhouse that tapers strongly toward the rear lends it a very dynamic appearance. The drag coefficient of 0.25 is the new benchmark in the SUV segment, where figures well over 0.30 are typical.
This concept contributes considerably to the long range of more than 500 kilometers (310.7 mi). At speeds from 80 km/h (49.7 mph), electrically actuated aerodynamic elements on the engine hood, the flanks and at the rear end direct the flow of air as needed, thus improving the flow through and around the vehicle. Wind noise is low on board the car, and there are no engine noises in an electric car in any case. The fascination of electric driving unfolds in the silence.
The vertical separating edges on the side panels and the fully enclosed floor pan with its newly designed microstructures also contribute to reducing drag. Cameras replace the conventional exterior mirrors – another contribution to the excellent aerodynamics and also a foretaste of the future of driving. The cameras feature a high dynamic range (HDR) sensor and smoothly present the vehicle surroundings with 1.3 million pixels and 60 frames per second. The image from these virtual exterior mirrors is then transferred to two OLED displays built into the front section of the doors.
New light: Matrix laser and Matrix OLED technology
Audi presents the new design idiom of its e-tron models at the front of the technology study: The Singleframe grille emphasizes the width of the car and five horizontal aluminum slats link the OLED (organic light emitting diode) elements of the light signature graphically to one another. The bottom section of the grille bears an e-tron logo that lights up briefly to greet the driver and passengers when they get in. Also integrated into this section is a visually subtle compact sensor rack that includes most of the sensors for the driver assistance systems and the new systems for piloted driving.
The Audi e-tron quattro concept generates all the main lighting functions with Matrix laser technology, the next step in the development of automotive lighting technology. Broken down into tiny pixels, the beam of light from the Matrix laser headlights can illuminate the road in high resolution and with precise control.
The bottom section of the front end houses a new, distinctive lighting signature comprising five lighting elements. Each of these combines an LED luminary with an extremely flat blue OLED element. The OLED elements emit a homogeneous light, are dimmable and can present a variety of lighting scenarios. The usage of the Matrix laser OLED technology on the front end of the Audi e-tron quattro concept is a world first.
An LED light guide runs across the rear of the technology study, which joins the rear lights and, in turn, underscores the width of the car. Similar to the units up front, the rear lights are also split into two zones. The upper section contains nine OLED units arranged in a flat line that assume the tail light functions; three more overlapping units are below these.
The zFAS: control center for piloted driving
The concept study is equipped with all the technologies that Audi has developed for piloted driving: radar sensors, a 3-D video camera from partner Mobileye, ultrasonic sensors and a laser scanner. The data these supply come together in the central driver assistance controller (zFAS). 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 Audi production vehicles.
