The IndyCar Series landscape is set for significant changes in 2026 with several high-profile driver moves announced this week. Most notably, American racing star Colton Herta will transition to Formula 1 as Cadillac's test driver [INDYCAR.com](source6), while two-time IndyCar champion Will Power confirmed his departure from Team Penske to join Andretti Global [INDYCAR.com](source5).
The most surprising announcement came from Colton Herta, who will leave his established IndyCar position to pursue Formula 1 opportunities. As Cadillac's test driver, Herta will play a crucial role in the manufacturer's F1 program [Formula 1](source7). Former IndyCar driver Christian Lundgaard commented that Herta will face "a tough challenge" in adapting to the new racing format [Motorsport.com](source3).
Will Power's departure from Team Penske marks the end of an era in IndyCar racing. The two-time series champion [ESPN](source9) will join Andretti Global to drive the No. 26 car starting in 2026 [INDYCAR.com](source5). This move represents one of the most significant driver transfers in recent IndyCar history, as Power leaves the team where he achieved much of his success.
These driver movements are part of an accelerated "silly season" in IndyCar, with teams and drivers making early decisions about their futures [INDYCAR.com](source2). The rapid pace of announcements suggests teams are being proactive in securing top talent for the 2026 season.
Looking ahead to 2026, the series is also implementing schedule changes, including modifications to the Toronto race [FOX Sports](source4). These developments indicate a period of significant evolution for IndyCar, both in terms of driver lineup and race calendar structure.
