General Motors will fit native North American Charging Standard (NACS) ports to all 12 of its electric models across Cadillac, Chevrolet, and GMC for the 2027 model year, up from a single model with the port today. For 2026, only the Cadillac Optiq leaves the factory with a NACS inlet, leaving 10 models — including the 478-mile Chevrolet Silverado EV and the 465-mile Cadillac Escalade IQ — reliant on a GM-approved adapter to use NACS-equipped fast chargers. GM published a model-by-model status breakdown this week covering every current and announced vehicle in the lineup.
Highlights
- All 12 GM electric models across Cadillac, Chevrolet, and GMC are slated for native NACS ports in the 2027 model year
- Ten 2026 models still require an adapter at NACS stations, with GM-estimated ranges topping out at 478 miles on the Silverado EV and Sierra EV
- The Cadillac Optiq is the only 2026 model year GM EV with a factory NACS inlet, rated at up to a GM-estimated 317 miles
- The revived Chevrolet Bolt, sold as a 2027 model, carries a NACS port and an EPA-estimated 262 miles of range
Which GM EVs Have Native NACS Ports Today?
Two vehicles on sale now ship with the connector from the factory. The Optiq, Cadillac’s smallest electric SUV, made the switch for the 2026 model year and is rated at up to a GM-estimated 317 miles depending on configuration. The 2027 Chevrolet Bolt returned to market with a NACS charge port and an EPA-estimated 262 miles of range.
Every other GM electric vehicle currently sold under the Cadillac, Chevrolet, and GMC brands leaves the plant with a CCS port and reaches NACS hardware through an adapter. GM said earlier this year that it expects all of its EVs to launch with a standard NACS charging port by the 2027 model year.
Model-by-Model NACS Status
| Model | Native NACS, 2026 | Native NACS, 2027 | Maximum Range |
|---|---|---|---|
| Cadillac Escalade IQ | — | Yes | 465 miles (GM-estimated) |
| Cadillac Escalade IQL | — | Yes | 460 miles (GM-estimated) |
| Cadillac Lyriq | — | Yes | 326 miles (EPA-estimated) |
| Cadillac Optiq | Yes | Yes | 317 miles (GM-estimated) |
| Cadillac Vistiq | — | Yes | 305 miles (EPA-estimated) |
| Chevrolet Bolt | — | Yes | 262 miles (EPA-estimated) |
| Chevrolet Blazer EV | — | Yes | 312 miles (EPA-estimated) |
| Chevrolet Equinox EV | — | Yes | 319 miles (GM-estimated) |
| Chevrolet Silverado EV | — | Yes | 478 miles (GM-estimated) |
| GMC Hummer EV Pickup | — | Yes | 363 miles (GM-estimated) |
| GMC Hummer EV SUV | — | Yes | 319 miles (GM-estimated) |
| GMC Sierra EV | — | Yes | 478 miles (GM-estimated) |
GM notes that all range figures apply to a full charge and vary with ambient temperature, terrain, battery age and condition, loading, and vehicle use.
Do NACS-Native GM EVs Still Need an Adapter?
Yes, in the opposite direction. A GM EV with a factory NACS inlet requires a NACS-to-CCS adapter to use a CCS-equipped fast charger. The same vehicles can draw Level 1 or Level 2 power through a J-1772 cable with the appropriate adapter, sold as an accessory.
That two-way adapter requirement persists through the transition. Some public charging sites now carry both NACS and CCS connectors, and GM offers adapters covering either direction.
Energy Pass Consolidates Network Payments
GM’s Energy Pass, built into the MyChevrolet, MyCadillac, and MyGMC apps, combines registration and payment across multiple charging networks. Tesla Supercharger, IONNA, Electrify America, and ChargePoint are supported, with EVgo integration pending. GM says the feature will eventually activate sessions on some networks automatically after a one-time enrollment, handling payment without app interaction.
