Audi’s first BEVs will come from both the J1 and the even-earlier C-BEV platform, which was the first premium BEV platform developed inside the VW Group.
The "second wave" will be the all-new premium PPE architecture in 2021, developed jointly by Porsche and Audi.
This architecture will sit beneath all new BEV Audis, Lamborghinis (including the second-generation Urus and an unnamed sports sedan), Bentleys and Porsches.
And then will come the sports cars and supercars, giving the VW Group three purpose-built battery-electric car architectures within the next seven years.
It should also take some of the heat out of the turf wars between Porsche and Audi, which have been at loggerheads over the futures of the 911 and the R8.
Porsche has demanded Audi switch the next version of its mid-engined R8 supercar (and, therefore, Lamborghini’s next Huracan) to its 911 platform, though Audi Sport has pushed back, hard. Sources insist that uncompromising stances over the "engineering folly" of a front fuel tank location cost Audi Sport engineering head Stephan Reil and its president Stephan Winkelmann their jobs.
Yet the VW Group has shown faith in Porsche’s engineering, partly because of lingering Dieselgate effects and partly because Porsche is already seen as an electrification leader inside the group. More than half of its European Panameras are hybrids, while it expects more than half of all its cars to be electrified by 2025.
The SPE already has two confirmed body styles and sizes within Porsche, including a cheaper two-seat convertible, and at least two roles within Audi.
It could also go a long way towards making Lamborghini’s Terzo Millennio concept car a reality. Though it wouldn’t have the concept’s all-carbon layout, the SPE platform has been engineered to cope with both the upper and lower ends of Lamborghini’s supercar range.
