INGOLSTADT / LOS ANGELES, November 28, 2018 – Audi e-tron, the third: the brand
Four rings presents one of the stars of the 2018 auto show in the movie capital, Los Angeles. With the Audi e-tron GT concept with electric propulsion, a four-door coupe debuted as an exhibition car. Volume counter-production should follow in about two years.
The next electric Audi is launched, along with the Audi e-tron SUV and the Audi e-tron Sportback, scheduled for 2019. This time, the architecture at flat floor offers impressive proportions and a low center of gravity. 434 kW (590 hp) guarantee performance worthy of a sports car. The torque is transmitted to the wheels through the quattro permanent all-wheel drive with torque vectoring, as one would expect for such a dynamic Audi. The Audi Sport GmbH performance subsidiary is responsible for the further transformation of the car into a mass production model.
Inspiration from the wind tunnel: design and bodywork
Flat, wide and with a long wheelbase, these are the proportions of a classic Gran Turismo. And the concept Audi e-tron GT reflects these goals with its 4.9 meters (16.3 feet) in length, 1.96 meters
(6.4 feet) wide and 1.38 meters (4.5 feet) high. The light body of the four-door coupe is made of several materials. Here you have a carbon roof section as well as many aluminum components and high strength steel support elements. The technology of this automobile has been developed in close collaboration with Porsche. The design and characters are filled with Audi DNA.
The gently sloping roofline of the GT e-tron concept that extends to the rear echoes the brand's sportback configuration. This however is clearly supported in the future, paving the way for the next step in the evolution of the Audi design language. The cabin, which decreases sharply towards the rear, stands out from the current Audi models. The wheel arches and armrests are sculpted with strength and, with the unusual flat floor for an electric vehicle, visually emphasize the low center of gravity and dynamic potential of the Audi e-tron GT concept.
The wide lines and numerous functional elements of the bodywork, as well as the vents of the wheel arches and the solid rear diffuser, highlight its origins in the wind tunnel. A low drag coefficient that reduces fuel consumption and low lift visually characterize the design.
The threshold area between the wheel arches was pulled very outside, creating a distinctive contrast with the cabin. The threshold draws attention to the ground where the battery is and therefore the energy center of the Audi e-tron GT concept. The design of the twin five-spoke wheels is also aligned with their function. Their dynamic design ensures optimal ventilation of the brake discs while reducing drag. With tire sizes of 285/30, the 22-inch wheels are also very visible when viewed from the side.
The Audi Singleframe feature is located in the center of the front section. Compared to the two e-tron SUVs, its architecture is much more horizontal. The upper half comes with a body-color painted cover. Its surface structure recalls the typical honeycomb pattern of the grille of the Audi RS models – a visual signal that characterizes the Audi e-tron GT concept as a future product of Audi Sport GmbH.
In addition to the targeted airflow from the body, large air intakes at the front effectively cool the sets, the battery and the brakes. The hood with its airflow to the surface recalls the last two cars of the brand, the Aicon and PB18 e-tron. It is designed in such a way that the flow of air marries the body, thus reducing unwanted swirls.
The arrow-shaped front section also highlights matrix LED headlamps with high beam headlamps, highlighting the dynamic presence of the Audi e-tron GT concept even at a standstill. As we have already seen with the brand's current Visions vehicles, the light is also animated and welcomes the driver with a short sequence of functions, the wave of light that extends horizontally: a new signature which should be in serial production in the future. .
A bright strip runs across the width of the back. This strip dissipates on the outer edges, in the actual lighting units, into individual corner-shaped LED segments. This architecture connects the e-tron GT to the SUV e-tron series, which makes them immediately recognizable, even in the dark, like Audi electric cars.
The new kinetic dust of exterior color – a warm, dark color close to titanium – seems to be practical without being a pretentious "technoid". Depending on the incidence and movement of the light, it offers a significant contrast between the surfaces of the body. Matte aluminum elements tinged in the edge and edges of the notches in the window further accentuate these effects.
Sustainable Contemporary Atmosphere: Inner
Four doors, four seats with a wheelbase of 2.90 meters – the Audi e-tron GT concept offers, on the inside, a great ease of use on a daily basis, combined with a feeling of exceptional quality. The functional center of the cabin is located on the front left, visibly centered on the driver's seat. The center console, the large touch screen in the upper part and the line between the door rail and the cockpit frame the driver's workstation and perfectly integrate the driver ergonomically to the controls and infotainment of the Audi e -tron GT. The center console and the independent instrument cluster seem to float. The light colors in the upper part of the cockpit and the gradation from darker and darker to the ground create an impression of unobstructed width. Race-inspired sports seats in both rows of seats provide optimal lateral support even in tight turns.
Both the center instrument screen and the touch screen above the center console have a black finish. They emphasize the broad and calm design of the interior with its essentially horizontal basic architecture. Different configurations are available for monitors to present features based on driver preferences, including virtual instrument dials, easy-to-read navigation maps with range information, or various infotainment menu functions. They are controlled via the touch screen with tactile feedback.
With the concept car, designers have deliberately opted for the consistent use of sustainable materials – a clear statement of contemporary automotive design. Animal products are not used at all: the Audi e-tron GT concept is endowed with a vegan interior. Sophisticated synthetic leather is used on seats and other upholstery surfaces. Recycled fiber fabrics are used on seat cushions, armrests and center console. A microfiber material adorns the headliner and trim of the window pillars. Even the thick pile carpet is made from durable Econyl yarn, a recycled fiber made from used fishing nets.
The Audi e-tron GT concept, with its two luggage compartments, offers a multitude of options for a Gran Turismo. Here, it takes full advantage of its conceptual advantage as an electric car with compact power units. The rear with its large tailgate offers a luggage capacity of up to 450 liters (15.9 cubic feet). Under the hood, there is an extra capacity of 100 liters (3.5 cubic feet).
Performance and Scope: Training
The power of the 434-kilowatt (590-horsepower) system is an impressive figure for the potential of all-electric propulsion. Separate electric motors are mounted on the front and rear axles. In both cases, it is synchronous motors with permanent excitation. They applied the torque on the road via all-wheel drive. Naturally, the new Audi e-tron GT concept is also a real quattro. An electric quattro to be precise because there is no mechanical link between the front axle and the rear axle. The electronic control system coordinates the drive between the axles as well as between the left and right wheels. This means optimal traction and just the amount of slip you want.
In the future, the vehicle should accelerate from 0 to 100 km / h in about 3.5 seconds before moving to 200 km / h in less than 12 seconds. The maximum speed is set at 240 km / h to maximize range. One feature that the competition is not able to grant is the ability to fully utilize the potential for acceleration of the drive several times in a row. Everywhere else, the drive switches to overdrive mode for thermal reasons, but the Audi e-tron GT concept can offer the driver the full potential of the engines and the battery thanks to its sophisticated cooling strategy.
The concept car will have a range of over 400 km, determined according to the new WLTP standard. The energy required for driving comes from a lithium-ion battery of over 90 kWh, which occupies the entire surface under the floor between the front and rear axles thanks to its flat design. The decisive advantage of this model lies in the extremely low center of gravity of the car, comparable to that of the Audi R8, which decisively benefits the dynamic behavior. The four-wheel drive makes it a perfect synthesis of the agility and precision of a sports car, enhanced with superb directional stability.
The recovery system increases the range up to 30% on Audi electric vehicles – it's essential even with a car as sporty as the Audi e-tron GT concept. The recovery concerns both the two electric motors and the electrohydraulically integrated braking control system. Different recovery modes are combined: manual freewheel recovery using shift paddles, automatic freewheel recovery via predictive efficiency aid and brake recovery with transition to smooth electrical and hydraulic deceleration. Up to 0.3 g, the Audi e-tron GT concept recovers energy only via electric motors, without using the conventional brake, which covers more than 90% of decelerations. As a result, the energy is returned to the battery during virtually all normal braking maneuvers. Wheel brakes are only involved when the driver decelerates more than 0.3 g using the brake pedal. The Audi e-tron GT concept features high-performance ceramic discs that also work with a number of extreme decelerations without compromising braking performance.
Reduces charging times: 800-volt charging system
The concept battery Audi e-tron GT can be charged in several ways: using a cable connected behind the flap of the left front fender or using a contactless induction with Audi Wireless Charging. Here, a loading mat with integrated coil is permanently installed on the floor where the car must be parked and connected to the power supply. The alternating magnetic field induces an AC voltage in the secondary coil installed in the floor of the car, through the air gap. With a load capacity of 11 kW, the Audi e-tron GT concept can be recharged completely overnight.
Wired charging is much faster because the four-door coupe is equipped with an 800-volt system. This significantly reduces charging times compared to conventional systems currently in use. Thus, it takes about 20 minutes to recharge the battery to 80% of its capacity, which gives it a range of more than 320 km (WLTP). However, the GT e-tron concept can also be reloaded at low-voltage charging points, giving the driver access to the entire charging network.
Audi: The ongoing electric offensive
The four-ring brand launched its electric offensive with the world premiere of the all-electric SUV Audi e-tron in September 2018. By 2025, Audi will offer twelve fully electric powered cars in the world's largest markets and will make about one -third of its sales with electrified models. Among the SUVs in this portfolio, the Audi e-tron and the Audi e-tron Sportback are expected to make their appearance in 2019. In addition, there will be a range of models to the classic bodywork such as the Audi E-tron and the Audi e-tron Sportback. before and sportback. The range will cover all relevant market segments, from the compact class to the normal class.
The concept car Audi e-tron GT, a very dynamic coupe with low floor, debuts at the LA auto show in 2018. The technology of this car was developed in collaboration with Porsche; The design and character of the GT e-tron concept are full of Audi DNA. The project will be developed into volume production models by the end of 2020. The first deliveries will be made to customers in early 2021.
Another common development department project at Audi and Porsche is the Premium Platform Electric (EPP). It will form the basis of several families of fully electric drive Audi models covering segments B to D.
