Stellantis adopts NACS to expand fast-charging availability in 2026

Stellantis will expand public fast-charging access for its battery electric vehicle customers through the adoption of the North American Charging System, a move that will enable select models to use the Tesla Supercharger network beginning in 2026. The announcement covers Stellantis operations in North America, Japan, and South Korea, and represents an effort by the automaker to broaden the availability of reliable, high-speed charging infrastructure across multiple markets.

The transition to the North American Charging System affects vehicles in the United States and Canada first, with access scheduled to begin in early 2026. Availability in Japan and South Korea is set to follow in 2027. Once implemented, the shift will open more than 28,000 Tesla Supercharger connectors to Stellantis customers across the five countries where the system will apply. Currently, Tesla maintains the largest fast-charging network in the United States and one of the largest globally, and access to it has become a priority for several automakers seeking to address consumer concerns about charging reliability and long-distance usability.

Stellantis will phase in compatibility over several vehicle cycles. Initial models with access are expected to include current and upcoming products already developed for North American markets. The company indicated that its existing BEVs, such as the Jeep Wagoneer S and the Dodge Charger Daytona, will be among the first to gain access. These models are due to enter or expand their presence in the U.S. market before the 2026 target date. The upcoming Jeep Recon, scheduled for release in 2026, is also confirmed to be part of the early wave of vehicles that will be able to use the Tesla Supercharger system.

Stellantis stated that additional products will be added as they enter the market, although the company did not disclose specific models beyond those already named. It also did not publish technical details about the planned adapter solutions or any hardware modifications necessary for existing vehicles. That information, according to the announcement, will be clarified at a later date for each global region involved. The company said only that compatibility solutions will be dependent on model type, market, and production timing.

The move aligns Stellantis with a broader industry trend of transitioning to Tesla’s connector standard. Over the past two years, several major automakers have adopted or committed to adopting the North American Charging System. This has resulted in a growing expectation that the NACS connector may become a de facto charging standard in the region, although separate efforts such as the SAE J3400 standardization process are still underway. For consumers, the shift has the potential to reduce the complexity associated with multiple plug types and charging protocols.

For Stellantis, access to a larger charging network addresses one of the main factors affecting consumer interest in EV adoption. Surveys in the United States and globally have repeatedly cited charging availability as a significant concern among potential BEV buyers. Public fast-charging infrastructure in North America remains in a development phase, with reliability varying across providers. The Tesla Supercharger network, which is widely regarded as one of the more consistent high-power charging systems in operation, has become a key differentiator in the EV market. By integrating NACS, Stellantis is attempting to mitigate concerns that its customers may face more limited charging options compared to owners of vehicles from competitors that have already completed similar transitions.

The collaboration does not change Stellantis’ own charging strategies, which also include participation in the IONNA charging joint venture formed alongside several other automakers. That network is expected to deploy thousands of additional fast-charging stations in the coming years. Stellantis’ adoption of the Tesla system operates in parallel with, rather than in place of, those efforts. As a result, future Stellantis customers are likely to have access to multiple charging ecosystems, depending on geographic region and the pace at which new stations come online.

Within the announcement, the company described the adoption of the new connector as consistent with its stated position of offering consumers what it refers to as “freedom of choice.” The phrase reflects Stellantis’ broader product strategy, which includes multiple propulsion systems across its brands. Stellantis currently sells internal combustion, hybrid, plug-in hybrid, and battery electric vehicles, depending on model and market. The company has emphasized that its product decisions are informed by customer demand rather than a singular, universal approach to electrification across all markets.

Stellantis said the addition of Tesla Supercharger access will give customers more flexibility in how they plan travel, particularly for long-distance routes where fast charging is essential. In the U.S. and Canada, the Supercharger network is concentrated along major interstate corridors, regional travel hubs, and high-traffic metropolitan areas. For many EV owners, fast-charging access can be a determining factor in trip planning. With the transition to NACS, Stellantis drivers may gain access to a significantly larger number of locations than the networks currently available through CCS1-equipped public chargers alone.

The announcement also referenced upcoming information that will outline which Stellantis models will require adapters, and what form those adapters will take. For some automakers, early NACS integration has required interim solutions in the form of adapter hardware before vehicles are redesigned with native NACS ports. Stellantis did not state whether its 2026 and later models will include a physical NACS port or rely on adapters during the early phases of the rollout. It also did not clarify whether any existing models will be retrofitted or whether adapter access will be offered only to vehicles explicitly designed for compatibility.

The decision to adopt NACS has implications for Stellantis’ electric vehicle strategy in North America, where the company has invested in a number of electric platforms under its Dare Forward 2030 plan. Stellantis intends to significantly increase the number of available EVs across its portfolio, which includes Jeep, Ram, Dodge, Chrysler, Fiat, Alfa Romeo, and other brands operating in global markets. Expanding charging access is viewed as a necessary component of this strategy.

In Japan and South Korea, where adoption is targeted for 2027, the EV landscape differs from the North American market. These countries have their own established charging standards and infrastructure. Implementing NACS access in these regions demonstrates an effort by Stellantis to provide cross-regional consistency for consumers and to align with global developments in charging technology. However, the company did not specify whether the Tesla Supercharger network in those countries is comparable in scale or availability to the North American system.

The announcement did not include information about potential pricing, billing arrangements, or membership models for Stellantis customers using Tesla’s network. Access models vary among manufacturers, and some automakers have negotiated discounted rates, membership perks, or integration into native vehicle navigation systems. Stellantis did not indicate whether similar capabilities, such as in-vehicle planning or Supercharger location mapping, will be incorporated into its upcoming software platforms.

Additional operational details, such as charging speed compatibility, vehicle limits, and potential restrictions, were also not provided. These factors often depend on battery architecture, onboard charging capacity, and the maximum power output the vehicle can accept. Tesla Supercharger sites typically support a mix of power levels, and charging performance can vary based on location, climate, and other factors.

The integration represents a step toward broader flexibility in EV charging, but the practical implications will become clearer as Stellantis releases more technical and logistical information. For now, the announcement confirms only the expected timeline, the initial markets, and a preliminary list of vehicles scheduled to gain access. Stellantis indicated that more details will be shared as the 2026 launch window approaches.
