2026 Mercedes-Benz CLA EV Gets NACS Port in U.S., But Tesla Superchargers Still Off Limits
Mercedes-Benz is making waves with its upcoming electric CLA model, promising an impressive 484-mile range. However, there’s a catch—this game-changing EV lacks compatibility with 400V DC chargers, which are widely used across Europe and the US.

Charging Restrictions: What’s the Issue?
Unlike other manufacturers that include voltage boosters to support both 400V and 800V charging networks, Mercedes-Benz has opted to restrict fast charging to only 800V chargers. This means CLA owners will not be able to use older 50kW DC chargers or most Tesla Superchargers, which predominantly operate on a 400V standard.
This omission appears to be a cost-saving measure, with Mercedes-Benz suggesting that most users will primarily charge their vehicles at home using AC connections. However, public fast-charging infrastructure in the US is still evolving, and many existing chargers operate on a 400V system, potentially causing inconvenience for new CLA owners.

Why It Matters for the US Market
The US charging infrastructure is dominated by Tesla’s Supercharger network, which primarily operates on 400V systems. Given that Mercedes-Benz is launching the CLA with a NACS charging port—Tesla’s proprietary design—this decision could present significant challenges for American drivers.
Without an additional converter or a CCS adapter, CLA owners may find themselves unable to utilize the most widely available fast-charging stations in the country. Rival brands such as Hyundai and Kia have addressed this issue by integrating internal voltage boosters, allowing their EVs to charge on both 400V and 800V networks. Porsche and Audi take a different approach with split-pack battery designs that accommodate older DC chargers.

Mercedes-Benz’s Response
A spokesperson for Mercedes-Benz stated that the share of 800V DC fast-charging stations is increasing and that drivers will be directed to compatible locations via the vehicle’s navigation system. However, for US consumers, this transition may take time. Many 400V chargers remain active, particularly in areas where EV adoption has been ongoing for years.
Reports suggest that the CLA EV sold in Norway may include a DC-to-DC booster to support 400V charging, but it remains unclear whether this option will be available in other markets, including the US.
