2027 GMC Hummer EV Switches to NACS Charging: What Buyers Need to Know
General Motors has officially confirmed that the 2027 Hummer EV Pickup and SUV will utilize the Tesla-style NACS charging port, and will also release a special 25th-anniversary edition model.
Overview
General Motors has confirmed that the 2027 Hummer EV Pickup and SUV will utilize the Tesla-style NACS charging port, and will also release a special 25th-anniversary edition model.
Adoption of the NACS Charging Standard
Until recently, most North American EVs utilized the CCS1 charging standard, with Tesla utilizing a proprietary charging standard known as NACS (North American Charging Standard, formerly SAE J3400). As Tesla’s Supercharger network represented the most comprehensive and reliable ultra-rapid charging network in the country, many automakers have transitioned to the NACS standard in order to provide their customers with access to Tesla’s Supercharger network, utilizing either native support or CCS1-to-NACS adapters.
The 2027 GMC Hummer EV Pickup and SUV will feature native NACS support beginning with the 2027 model year, meaning that owners will be able to take advantage of the extensive Tesla Supercharger network without the need for additional adapters. The NACS port will support both AC and DC charging, and will not suffer any losses in performance over the old CCS1 charging standard.
Bidirectional Vehicle-to-Home (V2H) Charging
A common concern among EV owners when a vehicle transitions from one charging standard to another is the loss of special features that may have been available on the old standard. In this case, however, owners of the 2027 GMC Hummer EV need not worry – the vehicle will retain its ability to perform bidirectional vehicle-to-home (V2H) charging, which allows a properly equipped EV to utilize its battery to provide backup power to a home during a blackout. This feature will continue to be available to owners of the 2027 GMC Hummer EV, although it will require the purchase of GM Energy home charging equipment and a V2H enablement kit in order to be used.
Other GM Vehicles Featuring Native NACS Support
The Hummer EV is not the first General Motors vehicle to adopt the NACS charging standard – GM has already begun the transition to the new standard, and the 2027 model year will see the introduction of native NACS support for a variety of EVs, including:
The Cadillac Lyriq and Lyriq-V, the Cadillac Vistiq, the Chevrolet Blazer EV, and the Chevrolet Equinox EV are all set to adopt native NACS support in the 2027 model year, and other GM EVs such as the Cadillac Escalade IQ, Escalade IQL, Celestiq, the Chevrolet Silverado EV, and the GMC Sierra EV are expected to follow in the coming years.
GM’s transition to the NACS standard reflects a broader trend among automakers to adopt the new standard, which has begun to supplant Tesla’s proprietary charging standard as the dominant standard among North American EVs.
25th Anniversary Edition: Icon | 25
In celebration of the Hummer brand’s 25th anniversary, GMC will release a special edition of the Hummer EV Pickup and SUV for the 2027 model year. Dubbed the Icon | 25, the special edition will be available for both the 2X and 3X trims of the Pickup and SUV.
The special edition will feature an exterior color inspired by the original Hummer H2, simply named Icon, while the interior will be available in Jet Black. The front shield of the vehicle will also be blacked out for a more aggressive look.
The Icon | 25 will also feature serialized badging on the vehicle’s dash, making each vehicle unique. The infotainment system will also feature custom graphics on the drive-mode screen, as well as an exclusive keepsake for the owner to commemorate the 25th anniversary of the Hummer brand.
Implications for Buyers
The transition of the GMC Hummer EV to the NACS charging standard has significant implications for buyers of the vehicle. In practical terms, this transition is beneficial to buyers of the vehicle, as it removes a potential concern for buyers regarding the availability of charging infrastructure for the vehicle. Practically speaking, the transition to the NACS standard means that owners of the 2027 GMC Hummer EV will have access to thousands of additional ultra-rapid charging stations without the need for additional adapters, home charging infrastructure will remain largely unchanged, and the ability to utilize the vehicle’s battery to provide backup power to the home in the case of an emergency will remain available.
In addition to the aforementioned benefits, the release of the 25th-anniversary edition of the Hummer EV means that buyers who are interested in the unique aesthetic of the original Hummer H2 will have the ability to do so, albeit in a modern interpretation of the classic design. However, buyers should also note that the 25th-anniversary edition will likely carry a significant premium over the standard editions of the vehicle, and will likely be available in limited numbers.
Production of the 2027 model year of the GMC Hummer EV is set to begin later this year, and more information regarding the release of the 2027 model year is expected to be released in the coming months.
