Today Mazda announced they will adopt Tesla's North American Charging Standard (NACS) beginning in 2025. That means future Mazda vehicles will come with Tesla's NACS connector instead of the CCS/J-1772 connectors their vehicles currently use, and will all gain access to over 15,000 Tesla Supercharger locations.
Currently, Mazda the only plug-in vehicle Mazda offers in North America is the CX-90 plug-in hybrid, which comes with a J-1772 connector. The CX-90 will NOT be compatible with Tesla Superchargers, as it is only capable of Level 2 charging (it can use Tesla's level 2 Destination Chargers with an adapter). Previously Mazda offered the MX-30, a short-lived fully electric crossover that was discontinued in North America for 2024. The MX-30 uses the CCS plug, and those models can presumably use an adapter for Supercharger access once an adapter becomes available sometimes in 2024.
Other automakers in North America including GM, Ford, Honda, Acura, Toyota, Lexus, Kia, Hyundai, Nissan, Genesis, BMW, Mini, Mercedes-Benz, Rolls Royce, Jaguar, Subaru, Volvo, Polestar, Lucid, Rivian, Fisker, and Aptera have all committed to adopting NACS. Several brands like Lotus, Lamborghini, Bugatti, Bentley, and Infiniti have not made announcements, but are part of automotive groups who have announced support for sister brands. Notable hold outs include Stellantis (Dodge, Chrysler, Jeep, RAM, Fiat, Alfa Romeo, Maserati).
