The Audi A6 e-tron concept debuted at the Auto Shanghai 2021 trade fair as the forerunner of a family of all-electric volume models. Audi is now launching the A6 e-tron in Sportback and Avant variants.
As the second model on the PPE platform, the upper mid-size vehicle picks up on the familiar product strengths of performance, range, efficiency, and charging. It is also the platform’s first model with a flat floor concept.
The A6 e-tron and S6 e-tron can be ordered from September 2024 as Sportback and Avant versions. Prices at market launch are €75,600 for the A6 Sportback e-tron performance and €99,500 for the Audi S6 Sportback e-tron.
Efficient electric motors and a lithium-ion battery newly developed for the PPE consisting of twelve modules and 180 prismatic cells with a total gross capacity of 100 kWh (94.9 kWh net) deliver a range of up to 756 kilometers (A6 Sportback e-tron ) and up to 720 kilometers (A6 Avant e-tron ).
With a system output of up to 270 kW in the A6 Sportback/Avant e-tron has power consumption of 17.0-14.0 kWh/100 km (62.1 mi) combined. The Audi A6 e-tron performance accelerates from zero to 100 km/h in 5.4 seconds. Its top speed is 210 km/h. The S6 e-tron provides a system output of 370 kW (405 kW with launch control).
The S6 Sportback e-tron and the S6 Avant e-tron accelerate from 0 to 100 km/h in 3.9 seconds with power consumption of 17.4-15.7 kWh/100 km (62.1 mi) combined. Top speed is 240 km/h. Its range is up to 675 kilometers (S6 Sportback e-tron ) and up to 647 kilometers (S6 Avant e-tron).
The A6 e-tron performance (270 kW) with rear-wheel drive and the S6 e-tron (370 kW) with quattro all-wheel drive, both as Sportback and Avant, will be available on launch. Depending on the market, further models with rear-wheel drive or quattro all-wheel drive will follow at a later date.
Due to 800-volt technology and a maximum DC charging capacity of 270 kW as standard, short charging stops are possible with the Audi A6 e-tron. This means the A6 Sportback e-tron performance can be recharged at an appropriate charging station (High Power Charging, HPC) for a range of up to 310 kilometers in just ten minutes.
The State of Charge (SoC) increases from 10 to 80 percent in 21 minutes. Intelligent high-performance and predictive thermal management are key components of this charging performance. Equipped with Plug & Charge, the vehicle authorizes itself at compatible charging stations when the charging cable is plugged in and activates the charging process. The charging process is fully automatic.
If a charging station works with 400-volt technology, the Audi A6 e-tron can use bank charging. To enable this, the 800-volt battery is split into two banks, each with a voltage of 400 volts, which can then be charged in parallel with up to 135 kW. AC charging with up to 11 kW is possible at standard home chargers. A 22 kW AC charging option will be offered later.
The advanced recuperation (regenerative braking) system is an important component in increasing the efficiency and range of the Audi A6 e-tron. This system can handle around 95% of everyday braking processes. The Audi A6 e-tron recuperates up to 220 kW. The temperature and the battery’s state of charge play a key role here. Recuperation occurs on the front and rear axles, with minor deceleration handled by the rear axle for efficiency reasons. In addition, a higher regenerative braking performance is possible on the rear axle due to the more powerful electric motor.
The integrated Brake System (iBS) that is familiar in previous e-tron models has been enhanced significantly as part of the Premium Platform Electric. Now, the described axle-specific brake blending between the mechanical friction brake and regenerative braking via the electric motors is possible.
The Audi A6 e-tron also offers the option of two-stage recuperation, which can be adjusted using the paddles on the steering wheel. Coasting is also possible. Here, the vehicle rolls without additional drag when the driver takes their foot off the accelerator pedal. Another variant of the A6 e-tron is the “B” driving mode, which comes close to what is colloquially called the “one-pedal feeling”. This mode offers the strongest recuperation deceleration. With an anticipatory driving style, almost all deceleration can be managed without pressing the brake pedal in driving mode “B”.
The adaptive driving assistant plus is a new feature of the A6 e-tron. It supports the driver when accelerating, braking, maintaining speed and the set distance, and with lane guidance. This can increase driving comfort, especially on long journeys. In addition to various sensors, depending on the region, the system uses high-resolution map data and swarm data from other vehicles aggregated in the cloud to improve driving behavior. Applying this fusion of information, the vehicle calculates the route ahead to enable a comfortable driving experience across the entire speed range and in traffic jams.
Park assist plus, a reversing camera, the traffic sign-based speed limiter, camera-based traffic sign recognition, adaptive cruise control, park assist plus with distance display, lane departure warning, and distraction and drowsiness warning will come as standard at market launch.
