Apple's Apple CarPlay Ultra has so far launched only with Aston Martin, while its broader rollout remains unclear despite earlier promises. Although several brands—including Hyundai, Kia, Porsche, and Ford—are still listed as partners (with Hyundai possibly launching support in an upcoming model), others like Mercedes-Benz, Audi, Volvo, Polestar, and Renault have backed out, and some partners have expressed lukewarm interest, leaving the platform's future adoption uncertain.
