Cosworth Unveils New High-Tech Steering Wheel for IndyCar

A provider of electronics and control systems for motorsports, Cosworth has unveiled its next-generation CCW Mk3 steering wheel, which is set to make its official debut in the 2025 IndyCar season. The company says the high-tech wheel has been meticulously designed, honed and engineered with direct input from IndyCar teams and drivers, incorporating a host of enhancements that push the limits of performance, ergonomics and functionality in high-level motorsport.

Cosworth’s commitment to engineering excellence in motorsports is underscored by the fact that the vast majority of IndyCar teams lining up on the grid for the season opener on March 2 will be using the CCW Mk3, a testament to its superior performance and reliability.

“Cosworth has been at the forefront of motorsport technology for decades, and our latest evolution of the CCW Mk3 steering wheel sets a new benchmark for performance in IndyCar,” said Ethan Duncan, U.S. motorsport manager, Cosworth. “This wheel is the result of extensive collaboration with teams and drivers to ensure it meets the highest standards in ergonomics, customization and race-critical functionality. By working closely with the IndyCar teams, we’ve created a product that balances cutting-edge technology with real-world usability.”

Collaboration & Customization at the Core

The development of the CCW Mk3 began with an in-depth consultation with IndyCar teams to understand their evolving needs. One of the primary focuses was ergonomics, ensuring the wheel simultaneously provides optimal comfort and efficiency. A key outcome of this collaboration was the decision to adopt a gripless design, allowing teams to apply bespoke grips tailored to individual driver preferences. This personalization feature ensures that each competitor can configure their steering wheel for maximum control and comfort during races.

Further refinements include an increase in wheel diameter from 280mm to 300mm, a new design that’s been engineered to meet specific IndyCar requirements for the 2025 season. Additionally, working in close collaboration with the IndyCar Medical Team, thumb clearance on the steering wheel has been enhanced to reduce the risk of injury in high-load racing scenarios, a crucial consideration in the fast-paced world of IndyCar.

The CCW Mk3 also introduces a push/pull paddle shifting system, a first for IndyCar, offering a more intuitive gear-shifting experience. Alongside this, rear button placements have been optimized based on driver feedback, ensuring crucial controls are within easy reach while maintaining a natural hand position.

From a technological standpoint, Cosworth has pushed the boundaries of steering wheel design with the integration of a fully configurable 5-inch TFT display, providing drivers with vital real-time data, allowing for split-second decision-making on track. RGB LED indicators—fully customizable for buttons, rotary switches and shift lights—enable teams to fine-tune visibility based on their racing environment and driver preference.

The CCW Mk3 also features 12 front-facing button inputs, four additional rear buttons, four front rotary switches, and two thumbwheel encoders, providing unparalleled levels of control and customization.

According to Cosworth, the development journey of the CCW Mk3 IndyCar steering wheel saw its 3D-printed prototype benefit from state-of-the-art additive manufacturing techniques, allowing the company’s engineering teams to test and refine its design rapidly before full-scale production. Feedback from teams and drivers played a crucial role in shaping the final iteration, ensuring it met the rigorous demands of IndyCar racing.

“The CCW Mk3 is a game-changer for IndyCar,” added Ethan. “From the push/pull paddle system to the customizable backlighting and TFT display, we have packed this wheel with advanced technology to give IndyCar drivers the best possible experience on track. Every function, every button and every ergonomic consideration has been fine-tuned to deliver precision and performance at the highest level of competition.”
