The NTT IndyCar Series will introduce new Cosworth Mk 3 steering wheels in 2025, with eight of eleven full-time teams already adopting the upgraded technology.

Key improvements in the Mk 3 model include:

• Wider frame diameter (increased from 284mm to 310mm)
• Larger data display screens
• More ergonomically placed buttons and rotary knobs
• Enhanced control features for new energy recovery systems

The new steering wheels, priced at approximately $19,000 each, will be supplied with Max Papis Innovations' quick-disconnect mechanism. Teams that have ordered the Mk 3 include:

• AJ Foyt Racing
• Arrow McLaren
• Chip Ganassi Racing
• Ed Carpenter Racing
• Juncos Hollinger Racing
• PREMA Racing
• Rahal Letterman Lanigan Racing
• Team Penske

Reigning champion Alex Palou of Chip Ganassi emphasizes the necessity of the upgrade, citing increased complexity in managing hybrid systems and energy monitoring during races.

The new design offers greater customization options, with additional buttons, toggles, and paddles, including controls on the rear of the wheel. While some drivers within the participating teams will continue using the previous Mk 2 model, the upgrade represents a significant advancement in race control technology.
