The “Premium Platform Electric” is completely new technology architecture. It will serve as the technology platform for these vehicles in the future. Beginning in late 2022, the first production cars in the C- and later also B-segment will be relaunched with PPE technology, including – a first in the market for electric vehicles – both SUVs with a high ground clearance and dynamically styled models with a lower ride height.
An electrified drive system already has a long tradition in the Audi A6 – after a full hybrid version that was released back in 2011, the current Audi A6 TFSIe made its debut in 2019 with a plug-in hybrid drive and an electric range of up to 91 kilometers (WLTP). Unlike the latter, however, the Audi A6 e-tron concept being exhibited at the Auto Shanghai 2021 show relies exclusively on electric power, based on the future PPE platform.
The 4.96-meter-long, 1.96-meter-wide, and 1.44-meter-high body (same as current members of the Audi A6/A7 series) is designed as a Sportback.
Large 22-inch wheels and short overhangs, the flat cabin, and the wide coupe roof arch give the vehicle proportions distinctly reminiscent of a sports car. The absence of hard edges results in smooth transitions between convex and concave surfaces throughout the body, as well as in soft shadows. The Audi A6 e-tron concept appears monolithic, as if from a single mold – particularly when viewed from the side.
Three small, high-resolution LED projectors are built in into each side of the body, transforming the ground beneath them into a stage when the doors are opened – small extended dynamic lighting effects greet the occupants with messages in their own language.
The PPE is designed exclusively for battery-electric drive systems and can therefore take full advantage of all the benefits of this technology. The key element of the future PPE fleet is a battery module between the axles that hold around 100 kWh of energy in the A6 e-tron concept.
The use of the entire vehicle base makes it possible to achieve a relatively flat layout for the battery. This means that for the first time, it will be possible to use this single platform for both vehicles with a high ground clearance and vehicles with a decidedly dynamic, flat architecture – such as the Audi A6 e-tron concept – without any changes to the basic architecture.
The battery size and wheelbase of PPE vehicles are scalable, making them suitable for use in different market segments. The ratio of a fairly long wheelbase and very short overhangs is something they will all have in common, however, and this, together with the large wheels, results in basic proportions that are simply perfect – and not just in terms of design.
The Audi A6 e-tron concept’s two electric motors are capable of delivering a total output of 350 kW and a torque of 800 Nm. The front wheels of the Audi A6 e-tron concept are connected via a five-link axle specially optimized for electric vehicles, with a multi-link axle in the rear. The concept car features Audi air suspension with adaptive dampers.
The heart of the Audi A6 e-tron concept’s drive technology – and that of all future PPE models – is the 800-volt charging technology. Like the Audi e-tron GT before it, this ensures that the Audi A6 e-tron concept’s battery can be charged with up to 270 kW in a very short span of time at fast-charging stations. This is a revolutionary technology which will enter the high-volume mid-range and luxury segments with the PPE for the very first time.
This technology makes charging times possible that come close to a stop to refuel a car powered by a conventional engine. Just 10 minutes are enough to charge the battery to a level sufficient to power the car more than 300 kilometres. And in less than 25 minutes, you can charge the Audi A6 e-tron concept’s 100 kWh battery from 5 to 80 per cent.
Together with a range of more than 700 kilometers – depending on the selected drive system and power output – the Audi A6 e-tron concept is uncompromisingly suitable for use as a primary vehicle.
