General Motors, through its Cadillac brand, remains determined to join the ranks of Formula 1.

The motorsport community was recently stunned by the news that Michael Andretti is stepping back from his role at Andretti Global.

Despite the FIA approving Andretti's bid to expand into F1, the application was rejected by Liberty Media-owned Formula 1, even with support from GM and Cadillac.

The rejection has sparked a U.S. political investigation into potential anti-competitive behavior within the sport, with some suggesting a link to Michael Andretti's decision to step back from his racing empire.

However, Cadillac's interest in Formula 1 has not waned, and the brand is still developing its own power unit for a 2028 debut.

France's Auto Hebdo quoted GM's executive director of motorsports, Eric Warren, as saying last month, "We will continue to follow the process in Formula 1. We've been working on it for two years. It's a process. We're intensively developing a power unit. We're intensively developing the car."

He added that there had been "positive meetings last week" and emphasized that Cadillac is "not giving up."

"We are committed to being involved and, one way or another, we will be there," he insisted.

Reports also suggest that Andretti's basic F1 car design will be completed by the end of this year, indicating that the project continues to move forward despite the recent setbacks.
