Honda, Chevy encouraged after first test of 2024 spec IndyCar engine



Bestinau got that-


It took an extra day and a lot of patience as cold weather and rain made freerunning a challenge, but the NTT IndyCar Series and its engine partners Chevrolet and Honda completed a successful opening test for the new and more powerful 2024 combustion engines.

The three-day test held at the Indianapolis Motor Speedway road course gave Chevy and Honda a first look at how their 2.4-liter twin-turbo V6 powerplants performed under duress, and after driving anywhere from eight to ten hours. when conditions allowed, the test was hailed as a valuable exercise.

No significant issues were reported for either manufacturer, whose 2024 engines are expected to produce something like 800 horsepower and ground a combined 900 horsepower once the new energy recovery systems are included in the hybrid package.

“A big round of applause for the inspiring Honda men and women at HPD in California, where the Honda IndyCar engine was designed, simulated, manufactured, assembled and bench tested,” said David Salters, president and technical director of Honda Performance Development. “The bike ran well over the three days and we completed all the scheduled test items, thanks to Chip Ganassi Racing and Scott Dixon.

“The car ran flawlessly with great collaboration and feedback and we learned a lot. Getting our new powerplant on track is great, we have set ourselves these challenges to develop our people and technology here at HPD. Fun fact: Our California-designed and built race bike braved the icy conditions at Indy. We are proud of you – he even ventured out in the rain!”

While the exhaust note on the 2.4L TTV6s wasn’t very different from the current 2.2L TTV6s, the more powerful engines seemed to have slightly altered audio signatures.

“Props to the extremely knowledgeable fans in the land of social media who noticed a deeper gnarled note from our new HPD Indycar race engine,” said Salters. “It’s a brand new design from HPD and it definitely grabs your attention; not bad for a super-efficient biofuel racing engine. Well done to those HPD racing magicians.

“We’ve had a great test at Indy over the past three days. Despite the chilly temperatures, our HPD race bike is warm and ready for its hybrid friend to party with. We can’t wait to integrate the hybrid technology, improve powertrain performance and further enhance the great racing that is IndyCar.”

While the number of laps and times was not released, RACER understands that Chevy and Honda drove more than 500 miles each during the test, which kept Josef Newgarden and Will Power busy for Team Penske and Dixon in action for CGR and Honda.

“We had three very successful and productive days with the new Chevrolet 2.4L IndyCar engine,” said Rob Buckner, Chevrolet Engineering Program Manager for IndyCar. “This was a big milestone as we progressed a few years ago from the original concept of the 2.4L design and run extensively on the dyno, to installing the engine in a car and now the milestone event of turning our first laps on the Indianapolis Road. Class.

“We are incredibly grateful to all the men and women at Chevrolet Performance and our partners at Ilmor for their commitment to a highly successful track debut for the 2.4L engine platform. We could race this bike tomorrow, which is the utmost praise for a new bike. Special thanks to Team Penske for quickly building a reliable and safe test car, along with Josef Newgarden and Will Power for maintaining our prototype engine with top-notch feedback.”
