- General Motors will equip every 2027 model-year EV with a native NACS (SAE J3400) DC fast-charging port, covering all 12 EVs across Chevrolet, Cadillac, and GMC including the Escalade IQ, Lyriq, Silverado EV, and both Hummer EV models.
- Cadillac and Chevrolet already have early NACS adopters: the 2026 Cadillac Optiq and the 2027 Chevrolet Bolt (arriving in 2026) ship with built-in NACS ports ahead of the broader switch.
- GM's 2026 EVs — the Blazer EV, Equinox EV, Silverado EV, Lyriq, Vistiq, Escalade IQ, Escalade IQL, Sierra EV, and both Hummer EV models — still ship with CCS1 ports and require GM's approved $275 NACS DC adapter to charge at Tesla Superchargers.
- GM's Energy Pass, built into the MyChevrolet, MyCadillac, and MyGMC apps, registers and pays across Tesla Supercharger, IONNA, Electrify America, and ChargePoint — with EVgo on the way — together covering nearly 70% of US DC fast chargers.
- Energy Pass supports Plug & Charge authentication, which is live at IONNA and being expanded to other networks including Tesla Superchargers, allowing the vehicle itself to handle authentication while payment runs in the background.
- GM will charge $189 for its CCS1 DC adapter and $67 for a J1772 Level 2 adapter, or $256 for both — still required to access legacy charging hardware on 2027 EVs, while the NACS port unlocks more than 27,500 Tesla Superchargers natively.
Why it matters: For every 2027 EV buyer across Chevrolet, Cadillac, and GMC, native NACS access to more than 27,500 Tesla Superchargers eliminates the $275 adapter step that has defined GM charging since the NACS switch — and the Energy Pass app consolidates authentication and payment across nearly 70% of US DC fast-charging stalls through a single account.
