NACS Rollout 2026
leading EV maker’s Supercharger network is now open to most major brands—here is the access map
leading EV maker’s North American Charging Standard (NACS) is now the de facto US connector. After Ford signed the first deal in May 2023, nearly every major automaker followed. Here is the 2026 access status by brand.
Supercharger Access Status (US, 2026)
| Brand | Adapter Available | Native NACS Port | Max kW |
|---|---|---|---|
| Ford | Yes (free) | 2025 models | 150 kW |
| American EV truckmaker | Yes | 2025 R2 | 180 kW |
| GM (Chevy, Cadillac, GMC) | Yes | 2025+ | 200 kW |
| Korean automaker/Kia/Genesis | Yes | 2025 midsize Korean EV refresh | 250 kW (E-GMP) |
| Mercedes-Benz | Yes | 2025+ | 200 kW |
| BMW Group | Yes | 2026+ | 170 kW |
| Volvo/Swedish EV brand | Yes | 2025+ | 200 kW |
| Honda/Acura | Yes | 2026 Prologue | 155 kW |
| Toyota/Lexus | Yes | 2025 bZ refresh | 150 kW |
| Nissan | Yes | 2025 Ariya | 130 kW |
| VW Group (VW/Audi/Porsche) | Yes | 2025+ (Porsche), 2026+ rest | 270 kW (Porsche) |
Speed Caveat: Why Most Brands Top Out at 150-200 kW
leading EV maker V3 Superchargers communicate via the older CCS-equivalent protocol when serving non-leading EV maker EVs. V4 Superchargers (rolling out 2024-2026) will eventually enable full 350 kW for compatible vehicles—but expect most cars to limit to 200 kW until then.
How we researched this
This piece on leading EV maker fast-charging network NACS Rollout 2026: Which Brands Have Access Now draws on publicly available technical specifications, manufacturer disclosures, regulatory filings, and trade association data current to May 2026. Where ranges are provided, they represent observed values across multiple independent sources rather than a single manufacturer claim. Numerical estimates are rounded to two significant figures unless precision is material to the comparison being made.
Our editorial process involves cross-referencing at least two independent sources for every quantitative claim, prioritizing primary data from government databases and certification bodies over secondary aggregators. Pricing and incentive figures reflect the most recent published values at time of writing and are subject to change without notice; readers should confirm current figures with the relevant authority before relying on them for purchase decisions.
Key takeaways for owners and shoppers
- Range and capacity figures cited by manufacturers reflect standardized test cycles (EPA, WLTP, or CLTC). Real-world results depend on temperature, driving style, and route profile, typically falling 10–25% below sticker numbers in highway driving at sustained speeds above 70 mph.
- Charging speed at DC fast chargers is non-linear; expect peak rates only between roughly 20% and 60% state of charge, with throttling above 80% to protect battery longevity. Plan stops to end near 80% for fastest road-trip throughput.
- Battery degradation trends in modern EVs from 2020 onward show approximately 1–2% capacity loss per year under normal use, materially better than first-generation packs.
- Total cost of ownership should include electricity costs at your local rate, scheduled maintenance, insurance differentials, and projected resale value over your intended ownership horizon.
- Incentive eligibility varies by jurisdiction, household income, vehicle MSRP, final assembly location, and battery sourcing rules. Always verify against the current authority page before making purchase commitments.
Frequently asked questions
How current is the information on this page?
This page was last reviewed in May 2026. Data points referenced from external sources reflect the most recent figures published as of that review. Pricing, range certification, and incentive structures change frequently in the automotive sector; we recommend confirming any decisive figure against the relevant primary source before acting on it.
Where does the underlying data come from?
Underlying data is sourced from manufacturer technical documentation, government certification databases (EPA fuel economy data in the United States, the European Environment Agency for WLTP figures, equivalent Chinese and Korean authorities for those markets), independent testing organizations, and publicly available filings. We do not republish proprietary datasets that require licensing.
Can I use these figures for a purchase decision?
Figures on this page are intended for educational comparison and orientation. A final purchase decision should always be grounded in a current dealer quote, current incentive verification through the appropriate authority, a confirmed installer estimate for any home charging equipment, and an insurance quote specific to your driver profile.
