The new A8 will fully exploit its Porsche-Audi PPE platform technology
New flagship German saloon gets autonomous drive, 800V charging and will be among the longest-range EVs on sale
Arriving at the crest of a wave of more than 20 new Audi cars due over the next three years, the Audi A8 EV will be crucial in providing the foundation for the brand to overhaul its positioning and differentiate itself more clearly from its Volkswagen Group siblings with a focus on high-margin premium cars in all core segments.
Due to be unwrapped exactly 30 years after the 1994 unveiling of the first A8 – notable for pioneering an aluminium ‘spaceframe’ platform – the new flagship is set to once again spearhead a technological rebirth for Audi as it ramps up to go all-EV in just three years.
It will use the largest version of the Porsche/Audi-developed PPE platform that will make its debut this year under the new Q6 E-tron, and is set to feature the most potent powertrains and radical technology available to the German brand. As previewed in 2021 by the Grandsphere concept, the new A8 will shun the traditional three-box proportions of the four previous generations.
Armed with a sizeable, 120kWh lithium ion battery, which is expected to make production, the Grandsphere had a claimed 466-mile range. That figure is expected to decrease slightly when the car dons numberplates and is fully homologated but it should still offer one of the longest ranges of any EV on sale.
The car will also be equipped with 800V charging functionality so will be one of the fastest to top up, netting a maximum charging speed of 270kW.
More intriguingly, early indications suggest it could be the most powerful car in the Audi stable when it is launched. The concept packed 711bhp and 708lb ft – more than today’s V8-propelled Audi RS6 Competition – for a near-4.0sec 0-62mph, and while those figures will not be exactly replicated by the production car, they hint at an outright focus on performance.
The PPE platform can accommodate rear-wheel steering at up to 5deg for tighter turn-in, as well as an electronic locking rear differential for improved torque-vectoring behaviour, and these features are expected to be carried over to the new A8.
But while its performance stats and dynamic credentials will be headline attributes, the new A8 will be more technically remarkable for the advances it makes in self-driving ability.
The Grandsphere was designed around its theoretical capacity for level-four autonomy, with a retracting steering wheel and pedals, automatically adjusting seats with individual sound systems and a raft of gesture-controlled functions. The A8 will be more conventional inside, but the more recent Activesphere concept gives clues to Audi’s plans to usher in a step change in autonomous driving with its next-gen EVs.
“We don’t want to overload you” with information, Audi user experience boss Sid Odedra told Autocar recently, suggesting the Sphere concepts’ shunning of physical controls and traditional screens in favour of sensor controls and holographic projections is not far from what will become reality.
“We’re not giving you less, actually,” Odedra said of Audi’s new minimalist interior treatment. “We’re giving you more. With less, we’re going to give you more of a digital experience with less physical architecture.”
