The electric Audi A4 was supposed to prove that Volkswagen Group's next-generation platform actually works. Instead, it's already proving how far behind schedule that platform really is.
The A4 E-Tron will now enter production no earlier than March 2029, according to Audi Chief Executive Officer Gernot Döllner. The delay traces directly to technical snags with the Scalable Systems Platform (SSP), Volkswagen's next-generation EV architecture.
