IndyCar is gearing up for an exciting milestone as it prepares to test its new chassis, the Dallara IR28, on an oval track for the first time. Scheduled for September 9 and 10, this significant testing event will take place at the iconic Indianapolis Motor Speedway (IMS), a venue synonymous with motorsport history.
The testing sessions will run from 9 a.m. to 5 p.m. on both days, allowing teams and drivers to gather valuable data on the car's performance on the 2.5-mile oval. This will mark a pivotal moment for the IR28, which has already undergone extensive testing on the IMS road course earlier this month. Notable drivers, including Alexander Rossi and Alex Palou, have already had the opportunity to pilot the new chassis during those sessions, with Palou expressing optimism about the car's potential to set new track records.
The Dallara IR28 is designed with the hope of breaking long-standing records at IMS, including Arie Luyendyk's remarkable one-lap record of 237.498 mph and the four-lap qualifying record of 236.986 mph, both of which have remained unbeaten since 1996. Palou's confidence in the car's capabilities was evident after his testing, stating, "I think we’re going to break a lot of IndyCar records on all kinds of tracks." This sentiment reflects the anticipation surrounding the IR28 as it prepares for its debut on the oval.
Following the initial testing phase, the chassis will be sent to IndyCar's two engine manufacturers, Chevrolet and Honda, in late 2026 or early 2027. These manufacturers will then work on developing their new 2.4-liter twin-turbocharged V6 engines, which will be integrated into the car for further testing. A hybrid powertrain will also be added to enhance performance. Teams are expected to receive their new chassis for the first time in June 2027, marking a new era in IndyCar racing.
The upcoming oval test is a crucial step in the development of the Dallara IR28, showcasing IndyCar's commitment to innovation and performance. As the series continues to evolve, the anticipation builds not only for the new chassis but also for the exciting races that lie ahead in the 2028 season.
