General Motors is making a major change to its electric vehicles: every GM EV for the 2027 model year will get a native North American Charging Standard (NACS) port. Chevrolet, Cadillac and GMC models will all make the switch, allowing drivers to connect directly to compatible Tesla Superchargers and other NACS fast-charging networks without carrying a DC charging adapter.
According to a report by Electrek, the move covers GM’s entire 2027 EV lineup, including the Cadillac Escalade IQ, Escalade IQL, Lyriq, Optiq and Vistiq; Chevrolet Bolt EV, Blazer EV, Equinox EV and Silverado EV; and the GMC Hummer EV Pickup, Hummer EV SUV and Sierra EV.
GM is finally making fast charging less complicated
The change matters because charging standards have been one of the more frustrating parts of owning an EV. Most 2026 GM electric vehicles still use the older CCS1 connector, meaning owners need GM’s $275 NACS DC adapter to access compatible Tesla Superchargers and other NACS fast chargers.
The 2026 Cadillac Optiq has already made the transition, while the reborn Chevrolet Bolt, arriving in 2026 as a 2027 model, will also feature a native NACS port. Drivers buying a 2027 GM EV will still need adapters for some older charging infrastructure. CCS1 DC fast chargers will require a separate adapter, while most existing Level 2 charging equipment uses the J1772 connector. GM sells those adapters for $189 and $67, respectively, or $256 as a package.
For anyone shopping for a new GM EV, the native port should remove one particularly annoying piece of equipment from the charging routine. Plugging into a compatible Tesla Supercharger should work without reaching into the trunk for an adapter.
One charging app could make the experience even easier
GM is also trying to reduce the number of charging apps and accounts EV owners have to juggle. Energy Pass is integrated into the MyChevrolet, MyCadillac and MyGMC apps, allowing drivers to register and pay across multiple charging networks from a single account.
Supported networks currently include Tesla Supercharger, IONNA, Electrify America and ChargePoint, with EVgo planned for later. GM says the combined networks represent nearly 70% of U.S. DC fast chargers. Plug & Charge is also supported at compatible stations, allowing the vehicle to handle authentication while payment is processed automatically. The feature is already live at IONNA and is being expanded to additional networks, including Tesla Superchargers.
GM’s 2027 lineup should make fast charging considerably simpler, particularly for road trips. CCS1 and J1772 adapters will still be worth keeping in the trunk, though. The charging standard may be settling down, but the old infrastructure isn’t disappearing overnight.
