BYD is set to supply cost-effective, iron-based batteries for Audi’s Q6L e-tron, the inaugural electric vehicle model constructed on a dedicated premium EV architecture and manufactured in China by the German carmaker, as per a Tuesday report from financial media outlet CLS. Simultaneously, Chinese battery giant CATL is set to furnish Audi with pricier, more energy-dense, nickel-based batteries, according to individuals familiar with the matter, who declined to disclose further details. In March, the Volkswagen subsidiary announced plans to commence mass production of the Q6 e-tron and the A6-tron lineups in collaboration with partner FAW Group at their joint facility in the northeastern Chinese city of Changchun, with an annual capacity of 600,000 units by 2024. The Q6 e-tron, the inaugural model based on the PPE (Premium Platform Electric), a jointly developed EV platform by Audi and Porsche, has faced delays in its launch due to behind-schedule software development. Despite TechNode’s requests for comment, BYD and Audi have not responded. [CLS, in Chinese]
