Every GM EV for 2027 gets native NACS ports — no adapter for Tesla Superchargers

GM is standardizing its entire electric vehicle lineup on the North American Charging Standard. Every EV from Chevrolet, Cadillac, and GMC for the 2027 model year will come with a native NACS port, also known as SAE J3400. That means drivers can plug directly into compatible Tesla Superchargers and other NACS fast chargers without any adapter.

The 2026 Cadillac Optiq has already made the switch. The reborn Chevrolet Bolt, arriving in 2026 as a 2027 model, also has a native NACS port. For the 2027 model year, NACS will be standard across every EV GM currently sells or has confirmed for that year.

Most 2026 GM EVs still need an adapter, though. Apart from the Optiq, GM's 2026 models — including the Blazer EV, Equinox EV, Silverado EV, Lyriq, Vistiq, Escalade IQ and IQL, Sierra EV, and both Hummer EV versions — come with a CCS1 port. Owners of these vehicles need GM's approved NACS DC adapter, priced at $275, to charge at compatible Tesla Superchargers and other NACS fast chargers. The adapter works with more than 27,500 Tesla Supercharger stations, although some locations remain limited to Tesla vehicles only.

Buyers of 2027 GM EVs will face the opposite situation: they'll need an adapter to use fast chargers with CCS1 ports. They'll also need a J1772 adapter for most existing Level 2 chargers, including many home charging units. GM sells its CCS1 DC adapter for $189 and its J1772 adapter for $67, or both together as a $256 package.

GM is also working to streamline the charging experience. The company is aiming to consolidate access to multiple charging networks into a single app, so drivers can find, start, and pay for charging sessions across different providers without juggling several apps and accounts. This move is part of a broader push to make EV ownership more convenient as the automaker transitions its entire lineup to the NACS standard over the next few years.
