Flow-enhanced design with a drag coefficient of 0.25; a powerful, all-electric e-tron quattro drive with up to 370 kW – Audi is presenting the Audi e-tron quattro concept at the International Motor Show (IAA) 2015 in Frankfurt. The car is the company’s statement about the future of electric mobility: It is sporty, efficient and suitable for everyday use.
“Audi will present an all-electric, luxury-class sport SUV in early 2018. The Audi e-tron quattro concept provides a concrete foretaste of this,” says Prof. Dr. Ulrich Hackenberg, Member of the Audi Board of Management for Technical Development. “It combines driving pleasure with great range, an expressive design and excellent comfort.”
- A foretaste of the production version: The electric-powered Audi e-tron quattro concept
- Range of more than 500 kilometers (310.7 mi) for full everyday usability
- New concept combines aerodynamics and creative design solutions
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. Total output is 320 kW. The driver can even mobilize 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).
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. 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. 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. 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 induction charging. The charging process is very convenient. 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 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 to reduce 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 speed and the 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 manoeuvrable at low speeds.
Aerodynamic: The exterior design
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 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 car’s drag coefficient measures just 0.25 – a new best for the SUV segment, where figures are usually considerably over 0.30.
All of this contributes considerably to the long range of more than 500 kilometers (310.7 miles). At speeds from 80 km/h (49.7 mi), electrically actuated aerodynamic elements on the engine hood, the flanks and at the rear end direct the flow of air as needed to improve the flow through and around the vehicle. This is one example of the intensive development work in the wind tunnel. 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 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). Audi is developing Matrix OLED technology for use in production vehicles and is showing it for the first time in the concept study at the IAA.
The rear lights also comprise two sections. Each of the top zones features nine red OLED units for the tail light function, with three more below.
Deep integration: The interior
The package of the Audi e-tron quattro concept enables a spacious, comfortable interior for four persons and 615 liters (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 extremely thin films can be cut to any desired shape.
The new Audi virtual cockpit curved OLED is a further development of the Audi virtual cockpit that debuted in production vehicles in 2014. To the left and right below the fully-digital instrument cluster are two touch displays with black glass and a subtle aluminum frame. 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. Its spokes are equipped with contoured touch surfaces.
Below the selector lever on the center tunnel console are two more OLED displays for 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 sit on comfortable individual seats. They can use the OLED displays on the center 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 zFAS: Nerve center for piloted driving
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 data these supply come together 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.
- New Audi A4 family of models makes first major public appearance
- Audi e-tron quattro concept car offers outlook on the future
- Audi continues to make its TDI and TFSI more efficient
At the 2015 International Motor Show (IAA), which begins today in Frankfurt am Main, Audi is presenting many different new products. The main focus is on the new A4 model line and the near-production Audi e-tron quattro concept car – a sporty SUV with an all-electric drive. The company is also offering visitors glimpses of the future in four of the brand’s focal themes – Audi Sport, quattro, Audi Technologies and Audi ultra – and is presenting the entire range of its drive system concepts.
Audi continues to make its TDI and TFSI engines more efficient with new technologies. In this way, the brand is fully exploiting the potential of conventional engines. The CO2 champions of each model series bear the supplement “ultra”. The new Audi A4 2.0 TDI ultra is making its motor show debut at this year’s IAA.
In the SUV segment, the purely electric Audi e-tron quattro concept car is celebrating its world premiere. Also to be seen at the motor show are the Audi Q7 e-tron 3.0 TDI quattro as a plug-in hybrid with up to 56 km (34.8 mi) of all-electric range and the new Audi A4 g-tron. The latter consumes less than four kilograms (8.8 lb) of natural gas per 100 km (62.1 mi) in the standardized cycle. For customers, this means extremely low fuel costs with a total driving range of up to 950 km (590.3 mi). In addition, the new Audi Q7 and the new Audi A4 offer the broadest array of assistance systems of all production automobiles. They illustrate a preliminary stage of piloted driving. Audi is promoting the development of all of these technologies with great vigor – always with the goal of uniting maximum efficiency and safety with strong performance.
The new generation Audi A4 impresses with a balanced and sporty driving experience, a large selection of infotainment solutions and highly intelligent assistance systems such as adaptive cruise control including traffic jam assist. Up to 30 optional systems assist drivers. The mid-class model also attains top figures in efficiency. The A4 Sedan is extremely aerodynamic with a best-in-class Cd figure of 0.23. Its efficient overall concept is supported by lightweight and efficient engines such as the 2.0 TDI ultra with 110 kW (150 hp). In the Sedan, this engine reduces NEDC fuel consumption to 3.7 l/100 km (63.6 US mpg) with 95 g CO2 per km (152.9 g/mi). The newly developed 2.0 TFSI ultra is the equal to its diesel counterpart in all respects. Thanks to an innovative combustion process, the 190-hp gasoline engine has a low fuel consumption of 4.8 l/100 km (49.0 US mpg). This equates to CO2 emissions of 109 g/km (175.4 g/mi).
At Audi, the mobility of the future is sporty, charged with emotion and highly efficient – the Audi e-tron quattro concept technology concept car offers an outlook on the brand’s first large-scale production electric car that will arrive on the market in 2018. It is based on the second-generation modular longitudinal platform, which offers considerable degrees of freedom in configuring the drive system and package. The design of the sporty SUV is based in large part on aerodynamic requirements – with a Cd figure of 0.25, the car sets the benchmark in the SUV segment. The electric drive – with three electric motors that output up to 370 kW – follows the e-tron quattro concept. The lithium-ion battery in the car’s floor enables over 500 km (310.7 mi) of driving range and thereby full everyday practicality. Innovative technical solutions in the areas of controls and infotainment also deliver a high level of convenience and user friendliness. The Audi e-tron quattro concept comes equipped with the technology for piloted driving.
The Q7 e-tron 3.0 TDI quattro is the first TDI plug-in hybrid with quattro drive from Audi. With 275 kW (373 hp) of system power, it accelerates from a standstill to 100 km/h (62.1 mph) in 6.0 seconds. Its NEDC fuel consumption is 1.7 liters of diesel fuel per 100 km (138.4 US mpg), and it can be driven up to 56 km (34.8 mi) all- electrically – quietly, powerfully and with zero local emissions.
In the Q5 and A8 model lines, the brand with the four rings is presenting two new top models that mark the peak of sportiness in each of their segments. The Audi SQ5 TDI plus with a 3.0 TDI biturbo has a power output of 250 kW (340 hp), while the Audi S8 plus* has 445 kW (605 hp).
