The 2027 Mercedes G 580 EV Gets a NACS Port, More Range, and Faster Charging
Owners will need a separate NACS-to-J1772 adapter for AC charging at Tesla Supercharger stalls.
Mercedes-Benz has opened orders for the 2027 G 580 Electric in the United States, introducing a native NACS charging port, improved energy efficiency, and slightly faster DC fast charging capabilities compared to the previous model year.
What Happened
The 2027 model replaces the outgoing CCS1 connector with a dual-port setup located under a single door. This configuration includes a Tesla-style NACS inlet dedicated to DC fast charging and a J1772 port for Level 2 AC charging. While the vehicle comes with a free adapter for CCS1 DC chargers, it does not include an adapter for the NACS AC ports found at Tesla Supercharger sites, requiring owners to purchase a NACS-to-J1772 adapter separately if they wish to use those stalls for AC charging.
The update also brings improvements to charging speed and range. The 2027 G 580 can charge from 0 to 80% in 29 minutes, a reduction from the 32 minutes required by the 2026 model, although the maximum DC input remains 200 kW. This faster time is attributed to tweaked charging logic that improves average power draw. Additionally, the SUV’s energy consumption has dropped to 48 kWh/100 miles from 54 kWh/100 miles, resulting in an EPA-estimated range of 249 miles, a 10-mile increase over the previous version.
Why It Matters
The adoption of a native NACS port signals Mercedes-Benz’s alignment with the emerging North American charging standard, eliminating the need for a CCS-to-NACS adapter for DC fast charging at Tesla Superchargers. However, the split between NACS for DC and J1772 for AC creates a specific friction point for owners who rely on Tesla’s AC destination chargers, as they must source their own compatible adapter. The efficiency gains and modest range extension may help alleviate some range anxiety for buyers of this luxury off-roader, though the vehicle remains a high-consumption EV with a starting price of $165,200, including destination fees.
The Bottom Line
The 2027 Mercedes G 580 Electric offers incremental improvements in charging speed and range while integrating the NACS standard for DC fast charging. Buyers should be aware of the dual-port architecture and the potential need for a third-party adapter for AC charging at NACS-equipped locations.
