With the commitment of Volkswagen, Audi, Porsche, and Scout to shift to the Tesla-based North American Charging Standard (NACS)—and the Biden administration’s backing of the SAE standard behind NACS now being finalized—America is now on the path for a single fast-charging standard for electric vehicles.

The VW Group had remained one of the last holdouts among major automakers, with Stellantis remaining the only one left.

Many months ago, earlier this year, that future was not at all apparent. But the tide turned on May 25, 2023. 

That day, with a joint chat between Tesla CEO Elon Musk and Ford CEO Jim Farley, it was announced that Ford would adopt Tesla’s NACS connector in future EVs, starting in 2025, and that current Ford EVs would gain access to Tesla’s Supercharger network starting early 2024. 

The timing fit in with Ford’s future-product announcements, directly following a preview of the company’s Gen 2 EVs, including a three-row EV that would get 350 miles of range from a battery pack of around 100 kwh. 

“This is a really big deal for our customers,” Farley said then, pointing to the ease of use of Tesla’s connector and the reliability of it. 

Ford wasn’t the first to announce its allegiance to the Tesla port; that nod goes to California firm Aptera, which confirmed in November 2022 its three-wheeler would include only NACS. But Ford’s commitment was, for the auto industry, the turning point.

Since then, the cards fell quickly and decisively, with announcements seemingly made as soon as the ink dried rather than as part of product or EV ecosystem previews. Nearly all of the automakers made announcements that included similar details—with Supercharger access in 2025 and an adapter in early or mid-2024. Click through to the corresponding pieces below for details as other automakers committed to Tesla NACS:

General Motors – June 8

Rivian – June 20

Volvo – June 27

Polestar – June 29

Mercedes-Benz – July 9

Nissan – July 19

Fisker – August 16

Honda/Acura – August 22

Jaguar (but not Land Rover) – September 21

Hyundai, Kia, and Genesis – October 5

BMW, Mini, and Rolls-Royce – October 17

Toyota and Lexus – October 20

Subaru – November 2

Lucid – November 6

Volkswagen, Audi, Porsche, and Scout – December 19

Holdouts that still might make the leap include Stellantis, and the entire Volkswagen Group (VW, Porsche, Audi, and more).

As Green Car Reports has pointed out before, Tesla’s V4 hardware will likely be able to handle EV models that charge at 800 volts at the full rate. As for Tesla’s V3 hardware and earlier—essentially all North American hardware available on the Supercharger network at this time—those will always be limited to 400 volts or a bit higher.

GM’s eagerness to sign up for NACS, considering that latter point, still remains a puzzle, as the GMC Hummer EV, Chevrolet Silverado EV, and other upcoming large, 800-volt-charging vehicles with huge battery packs depend on 800 volts to keep road-trip charging times reasonable.

This dilemma some automakers face around 800-volt charging might be solved over the next couple years with two large-scale developments. One of those is Tesla’s rapid deployment of V4 Superchargers, partly in support of the Cybertruck. The other is the high-speed charging network from seven automakers that will create 30,000 connectors—all 350 kw or higher, while expected to include both CCS and NACS connectors.
