Audi is developing a fully electric successor to the TT, which will be based on Porsche’s new all-electric 718 Boxster platform. At last year’s Munich Motor Show, Audi previewed the design direction for the upcoming model with the Concept C. The project remains underway but is progressing slowly. Recent spy photos reveal that Audi is still testing mule vehicles modified from the electric Porsche 718, now fitted with more pronounced wheel arches—hinting at a wider track than the Porsche version. In April 2024, Audi announced that production of the new model will begin in 2027 at the Böllinger Höfe plant, which specializes in low-volume vehicle manufacturing. According to this timeline, series production is expected to commence in the second half of 2026, leaving Audi less than 600 days to finalize the vehicle’s development. Rather than being an entirely new, ground-up development, the car will leverage Porsche’s next-generation 718 platform, which has already undergone approximately four years of testing. While the future Porsche 718 will be offered in both electric and internal combustion variants, Audi’s TT successor is expected to be available exclusively as a battery-electric model. Specifics of the powertrain remain unclear but may include a detuned version of the Porsche 718’s electric motor, paired with an 800V architecture and support for high-speed DC fast charging. Despite sharing its technical underpinnings with Porsche, Audi will give the new model its own distinct design. The retractable hardtop showcased on the Concept C is likely to carry over, while the interior is expected to adopt a minimalist approach, avoiding an overreliance on screen-based layouts.
