The 2024 NTT INDYCAR SERIES season gets underway with the Firestone Grand Prix of St Petersburg presented by RP Funding next weekend. So far, we have 25 of the 27 full-time drivers in place, with Dale Coyne Racing as the only team that has yet to confirm their lineup. Jack Harvey has tested for the team twice, so he may be one of the drivers they will have on the grid next weekend.

NTT INDYCAR SERIES schedule highlights include traditional favorites and, new to 2024, a made-for-TV $1 Million Challenge at The Thermal Club – a spectacular racing event set among extraordinary scenery just a short drive from world’s premier entertainment market, a return to historic Milwaukee Mile for a thrilling doubleheader, evening racing at Iowa Speedway and World Wide Technology Raceway and a supercharged season finale at the Big Machine Music City Grand Prix at Nashville Superspeedway.

This year, TV cameras will again follow the series for the behind-the-scenes 100 Days To Indy, which will air on The CW in the build-up to the Greatest Spectacle In Racing, the 108th running of the Indianapolis 500 presented by Gainbridge, which takes place on Sunday, May, 26.

Speaking about the season ahead, President and CEO of Penske Entertainment Corporation Mark Miles commented saying:

“This is an era of tangible growth and tremendous opportunity for the NTT INDYCAR SERIES. “Rising attendance, combined with incredible fan engagement across our digital channels, increased merchandise sales and rising viewership and visibility are all signs of significant momentum. We look forward to continuing this rising tide, on and off the track, as the curtain rises on another intensely fought and captivating season.”

While the 2024 NTT INDYCAR SERIES season awaits the arrival of the 2.2-liter twin-turbocharged V-6 engine with hybrid technology after the Indianapolis 500 presented by Gainbridge, teams will push the limit until then with enhanced possibilities of track records with lighter chassis components prepared for the hybrid addition. They include a lighter, 3D-printed titanium aeroscreen top frame. Without compromising overall strength and durability, the new INDYCAR top frame saves seven pounds from the previous model.

Additionally, a switch to a magnesium gearbox casing and bellhousing – located between the INDYCAR SERIES combustion engine and the gearbox and will house the hybrid assist unit – will provide additional weight savings.

The hybrid system is made up of the Motor Generator Unit (MGU) and Energy Storage System (ESS). Teams will be free to use multiple strategies for regeneration and deployment as the power unit builds and transmits energy through the MGU before and after being saved in the ultracapacitor ESS. The additional horsepower is deployed through the same motor generator. The new powerplant unit will be used in addition to the traditional overtake (“push-to-pass”) option on road and street circuits. The combination of the traditional push-to-pass with the hybrid unit will provide over 100 additional horsepower.

Use of the new power unit will be available on ovals with manual and automatic regeneration options but only with manual deploy.

Since the start of on-track testing, 21,108 miles have been completed with the INDYCAR-specific hybrid unit.

To ensure a smooth and comfortable transition to the hybrid unit addition this summer, teams will not be assessed any grid penalties for unexpected hybrid unit changeouts.

From an officiating standpoint, updates for 2024 include:

Restart line
On restarts, drivers must remain in single file and are prohibited from passing until reaching a line designated in the last corner. Additionally, the EM Motorsports light panels positioned around the track will be illuminated green to supplement the traditional cloth flag waved at the start-finish line for both starts and restarts.

A split group practice on the Streets of St. Petersburg
Deployed on a trial basis in St. Petersburg, the field will be split into two groups following a 20-minute “All Cars” session to begin Practice 1. Following the 20-minute “All Cars” session, each group – split by odd and even numbered pit boxes – will receive two 10-minute segments on an alternating basis. As in qualifying, the clock in Segments One and Two will stop for the first red flag condition of each practice segment.
Updates for the 108th Running of the Indianapolis 500 presented by Gainbridge will be announced at a later date.

A 2023 NTT INDYCAR SERIES season that featured 7,753 passes, including on-track passing records set at six racetracks, and the most laps and miles completed in a season in over a decade is expected to continue to its record-making trajectory in 2024.

INDYCAR President Jay Frye said.

“The last few seasons have been unprecedented in terms of records and milestones. “Between the massive effort by Chevrolet and Honda with the hybrid unit and the perpetual partnership and input from our owners, teams and drivers, 2024 is expected to be even more competitive and one of the most unique seasons and championships we’ve ever had. We cannot wait to get started in St. Petersburg.”

The most sustainable era in INDYCAR SERIES history will continue as the series, its teams and events continue to work to develop green technologies. Highlights from 2023 included the first use of Shell’s 100% Renewable Race Fuel, continued use of renewable diesel for all INDYCAR team transporters supporting the series and use of Firestone Firehawk alternate race tires – on street circuits – made from guayule rubber.

The Indianapolis Motor Speedway was the first sport facility to achieve organizational certification through the Council for Responsible Sport while the Chevrolet Detroit Grand Prix presented by Lear and the Hy-Vee INDYCAR Race Weekend achieved gold-level event certification.

Other announcements are expected throughout the 2024 NTT INDYCAR SERIES season.
