All you need to know about IndyCar’s new chassis and engine plans for 2028
IndyCar recently announced their plans to introduce a new car for the 2028 season, the most significant technical change in over a decade. Dallara, the exclusive chassis supplier for the series since 2008, will design and construct this next-generation vehicle focusing on competition, powertrain technology, and safety improvements. The new chassis will be lighter, weighing 85-100 pounds less than the current DW12 model, aligning with Formula 1’s trend towards enhanced agility and efficiency. The car will feature a 2.4-liter twin-turbo V6 engine, slightly larger than the current 2.2-liter units from Chevrolet and Honda. Xtrac will provide the gearbox, aiming to reduce weight by 25 pounds for better performance. IndyCar plans to optimize the new car for all track types on its schedule, including superspeedways, short ovals, street circuits, and road courses. The series will maintain a low-voltage hybrid system introduced in 2024, with upgrades for longer deployment, increased horsepower, and improved overall performance. Track testing for the new car is set to begin in early 2026, with the aim of enhancing safety and ensuring competitive racing for the future, according to IndyCar President J. Douglas Boles.
