F1 officially adds Cadillac brand for new American team to join grid in 2026

Formula 1 will expand its grid in 2026 to make room for an American team that is partnered with General Motors, the series officially announced Monday.

“As the pinnacle of motorsports, F1 demands boundary-pushing innovation and excellence. It’s an honor for General Motors and Cadillac to join the world’s premier racing series, and we’re committed to competing with passion and integrity to elevate the sport for race fans around the world," GM President Mark Reuss said. "This is a global stage for us to demonstrate GM’s engineering expertise and technology leadership at an entirely new level.”

The approval ends years of wrangling that launched a U.S. Justice Department investigation into why Colorado-based Liberty Media, the commercial rights holder of F1, would not approve the team initially started by Michael Andretti.

Andretti in September stepped aside from leading his namesake organization, so the 11th team will be called Cadillac F1 and be run by new Andretti Global majority owners Dan Towriss and Mark Walter. The team will use Ferrari engines its first two years until GM has a Cadillac engine built for competition in time for the 2028 season.

Towriss is the the CEO and president of Group 1001 and entered motorsports via Andretti's IndyCar team when he signed on financial savings platform Gainbridge as a sponsor. Towriss is now a major part of the motorsports scene with ownership stakes in both Spire Motorsports' NASCAR team and Wayne Taylor Racing's sports car team.

Walter is the chief executive of financial services firm Guggenheim Partners and the controlling owner of both the World Series champion Los Angeles Dodgers and Premier League club Chelsea.

“We’re excited to partner with General Motors in bringing a dynamic presence to Formula 1," Towriss said. "Together, we’re assembling a world-class team that will embody American innovation and deliver unforgettable moments to race fans around the world.’’

Mario Andretti, the 1978 F1 world champion, will have an ambassador role with Cadillac F1. But his son, Michael, will have no official position with the organization now that he has scaled back his involvement with Andretti Global.

The approval has been in works for weeks but was held until after last weekend's Las Vegas Grand Prix to not overshadow the showcase event of the Liberty Media portfolio. Max Verstappen won his fourth consecutive championship in Saturday night's race, the third and final stop in the United States for the top motorsports series in the world.

Grid expansion in F1 is both infrequent and often unsuccessful. Four teams were granted entries in 2010 that should have pushed the grid to 13 teams and 26 cars for the first time since 1995. One team never made it to the grid and the other three had vanished by 2017.

There is only one American team on the current F1 grid — owned by California businessman Gene Haas — but it is not particularly competitive and does not field American drivers. Andretti’s dream was to field a truly American team with American drivers.

The fight to add this team has been going on for three-plus years and F1 initially denied the application despite approval from F1 sanctioning body FIA. The existing 10 teams, who have no voice in the matter, also largely opposed expansion because of the dilution in prize money and the billions of dollars they’ve already invested in the series.

Andretti in 2020 tried and failed to buy the existing Sauber team. From there, he applied for grid expansion and partnered with GM, the top-selling manufacturer in the United States. The inclusion of GM was championed by the FIA and president Mohammed Ben Sulayem, who said Michael Andretti’s application was the only one of seven applicants to meet all required criteria to expand F1’s current grid.

“General Motors is a huge global brand and powerhouse in the OEM world and is working with impressive partners," Ben Sulayem said Monday. "I am fully supportive of the efforts made by the FIA, Formula 1, GM and the team to maintain dialogue and work towards this outcome of an agreement in principle to progress this application."

Despite the FIA's acceptance of Andretti and General Motors from the start, F1 wasn't interested in Andretti — but did want GM. At one point, F1 asked GM to find another team to partner with besides Andretti. GM refused and F1 said it would revisit the Andretti application if and when Cadillac had an engine ready to compete.

“Formula 1 has maintained a dialogue with General Motors, and its partners at TWG Global, regarding the viability of an entry following the commercial assessment and decision made by Formula 1 in January 2024,” F1 said in a statement. “Over the course of this year, they have achieved operational milestones and made clear their commitment to brand the 11th team GM/Cadillac, and that GM will enter as an engine supplier at a later time. Formula 1 is therefore pleased to move forward with this application process."

Yet another major shift in the debate over grid expansion occurred earlier this month with the announced resignation of Liberty Media CEO Greg Maffei, who was largely believed to be one of the biggest opponents of the Andretti entry.

“With Formula 1’s continued growth plans in the US, we have always believed that welcoming an impressive US brand like GM/Cadillac to the grid and GM as a future power unit supplier could bring additional value and interest to the sport," Maffei said. "We credit the leadership of General Motors and their partners with significant progress in their readiness to enter Formula 1."
