IndyCar has showcased its new IR-28 chassis for the first time at an event reserved for a selection of media. This presentation is a crucial step for the series, as the new vehicle will complete its first laps on track during a two-day test at the 2.439-mile, 14-turn Indianapolis Motor Speedway.
The drivers who will pilot the new IR-28 are Alexander Rossi of Ed Carpenter Racing, winner of the 2016 Indianapolis 500, who will handle the first day, followed by Alex Palou of Chip Ganassi Racing, the current IndyCar champion.
The on-track debut of the IR-28 symbolizes the end of the DW12 chassis, which has been the foundation of competition since 2012. These years have seen multiple aerodynamic, safety, and engine configurations, and now the goal is to move toward a new era.
An innovative vision for record speed
Mark Sibla, senior vice president of competition and operations, explained the objectives behind the design of the IR-28. Instead of modifying the old chassis, IndyCar has collaborated with Dallara to create an entirely new design.
According to Sibla, the new chassis will become a benchmark in terms of performance and safety, enabling the possibility of breaking track records thanks to a more powerful 2.4-liter engine and a reduced weight of approximately 100 pounds.
Progressive development strategy
The vice president of competition, Mike O’Gara, is responsible for managing testing and the schedule of deployments. After an initial ‘mule car’ equipped with prototype components, the next step will involve the use of engines from manufacturers without hybridization to verify their functionality.
Chassis testing will focus on aerodynamics and mechanical characteristics, aiming to ensure optimal performance before releasing them to race entry manufacturers.
Aerodynamic improvements for a better spectacle
One of the priorities of the IR-28 is to enhance competition through the management of turbulent air generated by the car. O’Gara has mentioned that the new design must improve race conditions compared to the current one.
To facilitate overtaking during races, ‘turbulence conditioners’ have been incorporated behind the front wheels, while safety has been improved in the body design.
Safety and comfort for the driver
The new chassis prioritizes not only performance but also driver safety. With a wide cockpit design, the IR-28 exceeds FIA standard requirements, providing greater comfort and adjustments for different driver sizes.
Additionally, the cockpit cooling system has been updated, eliminating the external ducts that created drag and replacing them with integrated channels.
Adaptability and cost control
To maintain cost control for teams, rules on initial developments have been established. This will allow teams to gradually adapt to the new system, thus avoiding an excessive financial burden in the short term.
With a long-term vision, IndyCar will seek regular renewal of the chassis design to remain competitive and appealing to fans, while ensuring a structured path for technological growth.
