Michael Andretti will step back from his position as Chairman and CEO of Andretti Global, he confirmed Monday in an open letter.
The 62-year-old will take on advisory role with the organisation, with Dan Towriss instead set to take over day-to-day operational responsibilities.
Towriss, a native of Indiana, is also the president and CEO of the Group 1001 financial services company based out of Zionsville.
Andretti Global was formerly known as Andretti Autosport before a rebranding in 2023, which came as part of a to date unsuccessful effort by Andretti and Towriss to pursue an entry into Formula 1.
It is present in sports car racing, most notably the IMSA WeatherTech SportsCar Championship, through a partnership with Wayne Taylor Racing that currently operates a two-car Acura GTP effort under the Wayne Taylor Racing with Andretti banner.
WTRAndretti also runs a Lamborghini Huracan GT3 EVO2 in the GTD class and operates a multi-car effort in Lamborghini Super Trofeo North America.
“For the past two decades, our team has seen the highest of highs and the lowest of lows,” Andretti wrote in an open letter posted to the team’s website.
“We’ve grown on a global level that I believe is still untouched in motorsport and we’ve seen some of the best talent in racing proudly wear the Andretti badge.
“Many of my best memories have come at the wheel of this organization, and I am so proud of what we have built.
“But decades of running flat out doesn’t come without sacrifice and, after much thought and reflection over the past several months, I came to the decision to take a step back.
“I’ve had a day-to-day operational role since even before I stepped out of the race car, and it’s time now to pass the baton to my partner and friend, Dan Towriss.
“But I am not going away – I will be serving as an advisor for the team and will be available to help wherever I can.
“While you might see me less at the racetrack, know that my passion for the sport and my support for our team, and its people, will remain unwavering.”
