Two longtime NASCAR executives have joined Andretti Global as part of a leadership restructuring following Michael Andretti’s decision to step down, The Associated Press has learned.
Doug Duchardt, a veteran with extensive experience in motorsports and automotive industries, has been appointed chief performance officer of motorsports at TWG Group, the organization now overseeing all former Andretti properties. Meanwhile, Jill Gregory, a former NASCAR vice president and seasoned marketing expert, has been named chief operating officer of a TWG subsidiary and president of Andretti Global.
The appointments were introduced during a team meeting at the Andretti race shop in Indiana on Wednesday morning, according to sources familiar with the matter. The TWG Group plans to formally announce its leadership changes next week, along with a new name for its motorsports division.
TWG Group is the investment firm of Mark Walter, CEO of Guggenheim Partners and owner of the Los Angeles Dodgers and Chelsea FC, and Dan Towriss, who initially joined Andretti Global as a sponsor and became a co-owner in 2022. Towriss now holds the majority ownership of Andretti’s race teams and serves as CEO of TWG Global’s motorsports arm.
Duchardt, who has had a distinguished career in NASCAR and IndyCar, most recently served as president of Spire Motorsports in 2024. He previously held leadership roles with Chip Ganassi Racing and Hendrick Motorsports and began his career at General Motors, which is partnered with TWG for the Cadillac F1 team launching in 2026. Duchardt will oversee all of TWG’s motorsports properties, including its partnerships with Spire Motorsports and Wayne Taylor Racing.
Jill Gregory will oversee Andretti Global’s IndyCar, Indy NXT, and Formula E programs. She replaces J-F Thormann, a longtime Andretti executive transitioning to head of driver development. Gregory, who previously held senior roles at NASCAR and Sprint Nextel, most recently worked as a consultant for Andretti Global in 2024.
This leadership restructuring marks a significant transition for Andretti Global under TWG’s ownership, with formal announcements expected next week.
