General Motors and TWG Motorsports have announced the creation of GM Performance Power Units LLC, a new venture aimed at developing Formula 1 engines for Cadillac’s entry into the sport by 2026.
The company named Russ O’Blenes, currently director of GM Motorsports Propulsion and Performance, as CEO of the new operation. O’Blenes brings over three decades of racing engineering experience to the role.
“We’re delighted to welcome Russ to this pivotal role,” said Dan Towriss, CEO of TWG Motorsports. “His expertise and leadership will be instrumental as we lay the foundation for Cadillac’s Formula 1 journey. Together with Team Principal Graeme Lowdon, they will lead the team in setting new standards of performance and innovation in the sport.”
GM President Mark Reuss highlighted O’Blenes’ track record in motorsports engineering. “Russ brings vast experience from many championship racing series, and has outstanding technical expertise, including spearheading our hybrid IMSA Cadillac and Corvette C8.R engines that are proven winners,” said Reuss. “In F1, we’re going to demonstrate GM’s engineering and technology capabilities on a global stage.”
The company has already begun development and testing of prototype engine technology. The program will focus on advancing GM’s capabilities in electrification, hybrid systems, sustainable fuels, and high-efficiency internal combustion engines.
A dedicated facility for Performance Power Units LLC will open near GM’s Charlotte Technical Center in 2026. Until the GM engines receive racing approval, the Cadillac Formula 1 Team will use Ferrari power units.
“I am truly excited to have the opportunity to build and lead the team that will bring an American built F1 power unit to the grid,” said O’Blenes.
The move represents another step in TWG Motorsports’ racing expansion, which includes ownership of Andretti Global, Wayne Taylor Racing, and Spire Motorsports, alongside its partnership with General Motors in the new Cadillac Formula 1 team.
