Audi has delayed its electric A4 until 2029, pushing back a model that was originally planned for production at its Ingolstadt plant in 2028. The postponement leaves a gap in the mid-sized electric executive segment, where Audi had hoped to compete with rivals including the BMW i3, the Mercedes C-Class EV and the Tesla Model 3. For a brand that has built much of its volume around the A4 family, the timing is significant.
The A4 has historically been central to Audi's sales. Its internal combustion version, now renamed the A5, has been a key volume model for the company. Delaying the electric counterpart means Audi will continue to depend on petrol and diesel products for longer in a segment where competitors are already well established with dedicated battery-electric alternatives, leaving the brand with less representation in a class that buyers are increasingly comparing across powertrains.
The setback is closely tied to the difficulties affecting the Volkswagen Group's Scalable Systems Platform, known as SSP. Announced in 2021, the platform was intended to replace several existing architectures, including MEB, PPE, MQB, MLB and MSB. Production had originally been slated to begin in 2026, and the group has projected that more than 40 million vehicles will eventually be built on SSP once it is fully rolled out across its brands.
The Audi delay follows a similar postponement for the Volkswagen Golf Mk9 electric model, which is being developed on the same platform. That pattern suggests the problems are not confined to a single model line but affect the shared architecture as a whole. Volkswagen's first SSP model, the T-Roc EV, is planned for production in Wolfsburg, while a successor to the Skoda Enyaq, also based on SSP, is set to be built in Mladá Boleslav. It remains unclear whether the latest revisions will alter the timing for the Skoda model, and no confirmed revised date has been given for it.
Software problems at Cariad, the group's software unit, sit at the centre of the SSP delays. The Cariad software platform was originally due in 2025, and the difficulties have pushed back the programme across several brands. To address the shortfall, Volkswagen has turned to the American company Rivian for electronics and software development outside China, a partnership that signals how the group is seeking outside expertise to recover lost ground on its own timetable.
Engineering changes requested by Audi have also added complexity. The brand has demanded revised footwells and a different battery packaging arrangement, and it is specifying a 48-volt electrical system in place of the more conventional 12-volt setup. Each of these requirements forces reworking of a shared architecture that is meant to serve several brands at once, so changes made for one model can ripple through the programmes of others. Taken together, these factors help explain why the A4's electric launch has slipped from 2028 to 2029, and why the wider rollout of SSP-based cars now faces a longer and less certain path.
