14 Oct
Summary
- New IndyCar IR28 chassis underwent rigorous testing at Sebring.
- Alexander Rossi completed 134 laps, focusing on practical performance.
- Significant cooling improvements noted for driver comfort and drivability.
Alexander Rossi recently completed a significant testing session for IndyCar's upcoming 2028 chassis, the Dallara IR28, at Sebring International Raceway. Piloting the car for 134 laps, Rossi focused on evaluating its real-world performance and durability, a shift from earlier tests aimed at confirming basic functionality. The Sebring track, known for its challenging bumps, provided a realistic simulation of street course conditions.
Rossi reported substantial progress in the IR28's cooling systems. He described the improvements as 'night-and-day,' significantly enhancing driver comfort and making the cockpit more drivable, even in the demanding Florida heat and humidity. This testing round, the third for the IR28, utilized driver feedback to refine the car before full production.
Dallara and IndyCar will now analyze the data and driver input gathered from these sessions. These insights will guide any necessary adjustments before manufacturing commences. The distribution of the new chassis to Chevrolet and Honda is anticipated in late 2026 or early 2027, marking a new era for the sport.
