General Motors is making a big shift with its electric lineup. Starting with the 2027 model year, every GM EV will come with a built-in North American Charging Standard port right from the factory.
That covers Chevrolet, Cadillac, and GMC models alike, letting drivers plug directly into compatible Tesla Superchargers and other NACS-based fast-charging networks without needing to carry around a separate adapter.
Electrek reports that this change spans GM’s full 2027 EV lineup. That includes the Cadillac Escalade IQ, Escalade IQL, Lyriq, Optiq, and Vistiq, the Chevrolet Bolt EV, Blazer EV, Equinox EV, and Silverado EV, plus the GMC Hummer EV Pickup, Hummer EV SUV, and Sierra EV.
GM and Native NACS Ports for Tesla Chargers
This shift addresses one of the more genuinely annoying parts of owning an EV. Most 2026 GM electric vehicles still rely on the older CCS1 connector, which means owners currently need a $275 NACS DC adapter from GM just to use a Tesla Supercharger or another NACS-based fast charger.

A couple of models have already made the jump early. The 2026 Cadillac Optiq already ships with native NACS, and the reborn Chevrolet Bolt, landing in 2026 as a 2027 model, will have it too.
That said, 2027 GM EV owners won’t be entirely adapter-free. Older CCS1 fast chargers still require a separate adapter, and most existing Level 2 chargers use the J1772 connector instead. GM prices those adapters at $189 and $67 individually, or $256 bundled together.
For anyone shopping for a new GM EV, this cuts out one genuinely annoying step in the charging process. Pulling up to a compatible Tesla Supercharger should just work, no digging through the trunk for an adapter first.
GM Charging App
GM is also working to cut down on the number of separate apps and accounts EV owners have to manage just to charge. Its Energy Pass feature now lives inside the MyChevrolet, MyCadillac, and MyGMC apps, letting drivers register and pay across several charging networks through one single account.

Right now, that covers Tesla Supercharger, IONNA, Electrify America, and ChargePoint, with EVgo set to join later.
GM says these networks combined make up nearly 70% of DC fast chargers across the US. Plug & Charge support rounds this out at compatible stations, letting the car handle authentication on its own so payment happens automatically in the background. It’s already active on IONNA and is rolling out to more networks, Tesla Superchargers included.
Put together, GM’s 2027 lineup should make fast charging noticeably less of a hassle, especially on road trips. That said, it’s still worth keeping CCS1 and J1772 adapters in the trunk for now. The charging standard landscape is stabilizing, but the older infrastructure isn’t going anywhere overnight.
