Audi partners with Porsche to launch 12 all-electric vehicles by 2025

With the electric powered Audi e-tron GT concept a four-door coupé is making its debut as a show car. The volume-production counterpart is set to follow in around two year. The next electric Audi is being launched, following in the footsteps of the Audi e-tron SUV and the Audi e-tron Sportback slated for 2019. This time with a flat-floor architecture that provides for exciting proportions and a low center of gravity. The performance subsidiary Audi Sport GmbH is responsible for subsequently transforming the car into a volume-production model.

434 kilowatts, 590 hp system power, that is an impressive figure for the potential of the all-electric drive. Separate electric motors are fitted to the front and rear axles. In both cases these are permanently excited synchronous motors. They put down the torque onto the road via all four driven wheels – naturally the new Audi e-tron GT concept is also a genuine quattro. An electric quattro to be precise, since there is no mechanical link between the front and rear axle. The electronic control system coordinates the drive between the axles as well as between left and right wheels. That means optimum traction and just the desired amount of slip.

In future, the vehicle should accelerate from 0 to 100 kmh in around 3.5 seconds before going on to 200 kmh in just over 12 seconds. The top speed is regulated at 240 kmh to maximise the range. One feature that not all the competition can match is the option of fully utilising the drive’s acceleration potential several times in succession. While elsewhere the drive is switched to overdrive for thermal considerations, the Audi e-tron GT concept can provide the driver with the full potential of both motors and the battery thanks to its sophisticated cooling strategy.

The range of the concept car will be over 400 kilometers, determined according to the new WLTP standard. The required drive energy comes from a lithium-ion battery with an energy content of more than 90 kWh, which takes up the entire underfloor area between the front and rear axle with its flat design. The decisive advantage of this design is the car’s extremely low center of gravity – comparable with that of the Audi R8 – which in turn decisively benefits dynamic handling. All-wheel steering translates this into a synthesis of sports car-like agility and precision, augmented by superb directional stability.

The recuperation system increases the range by up to 30% on Audi electric vehicles – this is essential even with such a sporty car as the Audi e-tron GT concept. The recuperation involves both the two electric motors and the electro-hydraulically integrated brake control system. Different recuperation modes are combined: manual coasting recuperation using the shift paddles, automatic coasting recuperation via the predictive efficiency assist, and brake recuperation with smooth transition between electric and hydraulic deceleration.

Up to 0.3g, the Audi e-tron GT concept recuperates energy solely via the electric motors, without using the conventional brake, that covers over 90% of all decelerations. As a result, energy is fed back to the battery in practically all normal braking maneuvers. The wheel brakes are involved only when the driver decelerates by more than 0.3 g using the brake pedal. The Audi e-tron GT concept features high-performance ceramic disks which also operate with multiple extreme decelerations without compromising braking performance.

The battery in the Audi e-tron GT concept can be charged in several ways: using a cable which is connected behind the flap in the left front wing, or by means of contactless induction with Audi Wireless Charging. Here a charging pad with integral coil is installed permanently on the floor where the car is to be parked, and connected to the power supply. The alternating magnetic field induces an alternating voltage in the secondary coil fitted in the floor of the car, across the air gap. With a charging output of 11 kW the Audi e-tron GT concept can be fully charged conveniently overnight.

Wired charging is much faster as the four-door coupé is fitted with an 800-volt system. This substantially reduces charging times compared with conventional systems that are currently in use. Thus it takes around 20 minutes to recharge the battery to 80% of its capacity, once again providing a range of more than 320 kilometers 198.8 mi WLTP. The e-tron GT concept can, however, also be recharged at charging points with lower voltages, providing the driver with access to the entire charging network.



The brand with the four rings 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 automobiles with all-electric drive in the most important markets worldwide and achieve roughly one-third of its sales with electrified models. The SUVs within this portfolio include the Audi e-tron and the Audi e-tron Sportback due to make its debut in 2019. In addition, there will be a range of models with classic body layout such as Avant and Sportback. The range will cover every relevant market segment from the compact to the full-size class.

The lightweight body of the four-door coupé is manufactured using a multi-material construction. Here you have a roof section made from carbon along with numerous aluminum components and supporting elements made from high-strength steel. The technology for this automobile was developed in close collaboration with Porsche. The broad lines and the numerous functional elements of the body as well as the air vents of the wheel arches and the solid rear diffuser emphasise its origins in the wind tunnel. A low drag coefficient that reduces fuel consumption and the low uplift visually characterise the design.

The sill area between the wheel arches has been drawn way outwards, creating a distinctive contrast with the cabin. The sill draws the eye to the underfloor area where the battery and thus the energy center of the Audi e-tron GT concept are located. Together with the targeted airflow of the body, large air inlets in the front effectively cool the assemblies, battery and brakes. The hood with its airflow on the surface echoes the brand’s two latest show cars, the Aicon and the PB18 e-tron. It is designed in such a way that the airflow hugs the body, thus reducing undesired swirl.

The arrow-shaped front section also emphasises the matrix LED headlights with laser high beam, underscoring the dynamic presence of the Audi e-tron GT concept even while stationary. As already seen with the brand’s current Visions vehicles, the light is also animated here and welcomes the driver with a short function sequence, the wave of light that extends horizontally: a new visual signature that is set to find its way into volume production in future.

The center console, the large touchscreen in the top section and the line from the door rail and cockpit frame the driver’s workplace, perfectly incorporate the driver ergonomically with the controls and the infotainment of the Audi e-tron GT. The center console and the freestanding instrument cluster seem to float. Various layouts are available for the monitors to present the functions depending on the driver’s preference, including virtual instrument dials, easy-to-read navigation maps with information on the range, or various infotainment function menus. They are controlled via the touchscreen with tactile feedback.

The Audi e-tron GT concept show car, a highly dynamic coupé with a low floor, is debuting at the Los Angeles Auto Show 2018. The technology in this automobile was developed in collaboration with Porsche; the design and character of the e-tron GT concept are packed full of unmistakable Audi DNA. The project will be developed into volume-production models by the end of 2020. Initial deliveries will be made to customers in early 2021. Another joint project of the development departments at Audi and Porsche is the Premium Platform Electric PPE. It will be the foundation for multiple Audi model families with all-electric drive covering the high-volume B through D segments.

The Audi Group, with its brands Audi, Ducati and Lamborghini, is one of the most successful manufacturers of automobiles and motorcycles in the premium segment. It is present in more than 100 markets worldwide and produces at 16 locations in twelve countries. In 2017, the Audi Group delivered to customers about 1.878 million automobiles of the Audi brand, 3,815 sports cars of the Lamborghini brand and 55,900 motorcycles of the Ducati brand.

The required drive energy comes from a lithium-ion battery with an energy content of more than 90 kWh.
