IndyCar Unveils 2028 Chassis Design with Major Technical Upgrades




IndyCar has officially revealed the preliminary designs for its eagerly anticipated 2028 Dallara chassis, with on-track evaluations scheduled to commence on August 1st. This marks a pivotal moment for the American open-wheel series as it prepares for a comprehensive technical overhaul.
The newly conceptualized Dallara IR-28, while bearing a visual resemblance to the current IR-18 model introduced in 2018, incorporates several key enhancements. Drivers and industry experts who received an early preview expressed considerable enthusiasm. Notable upgrades include a more spacious cockpit, redesigned front and rear aerodynamic elements, and an integrated aeroscreen for improved safety and a contemporary aesthetic. Powering these machines will be enlarged 2.4-liter turbocharged V-6 engines, provided by Chevrolet and Honda, capable of generating 760 horsepower. Furthermore, a significantly lighter and more efficient hybrid system, developed with components from XTrac, Helix, and BOLD Technologies, will be integrated, boasting 14 times the energy storage capacity of its predecessor and contributing to an overall weight reduction of approximately 100 pounds for the car.
IndyCar President Doug Boles emphasized that these advancements are set to usher in a new era for the sport, promising heightened wheel-to-wheel racing, record-breaking speeds, and unparalleled safety standards. The initial testing phase, starting at the Indianapolis Motor Speedway road course with seasoned drivers Alexander Rossi and Alex Palou, will be followed by further assessments at various venues throughout the autumn. Production of the IR-28 is slated to begin in early 2027 at Dallara’s facility in Italy, with teams expected to receive their first cars by spring. Long-time IndyCar competitor Will Power lauded the design, highlighting the seamless integration of updated aerodynamics with advanced safety features, resulting in a modern and aggressive appearance.
The introduction of the 2028 chassis represents a bold step forward for IndyCar, demonstrating a commitment to innovation, safety, and thrilling competition. This proactive evolution ensures the series remains at the forefront of motorsport, inspiring future generations of drivers and engineers while delivering exhilarating experiences for fans worldwide.
