The NTT IndyCar Series has only a couple races left before it is set to introduce a new hybrid component to its engines beginning at the start of the 2024 season.
Both Honda and Chevrolet have been testing multiple iterations of the hybrid systems over the past year, which employ a unique layout that places the batteries within the engine bellhousing.
According to Honda representatives, one of the biggest concerns from the manufacturers has been reliably sourcing components for the all-new design. But development has continued steadily regardless, and the weight of the system has been reduced drastically over the course of the past year.
The components have been put through ever more stressful tests, and so far seem to be holding up well enough for the series to continue on with the 2024 introduction timeline.
Scott Dixon has been tipped to be Honda’s designated test driver throughout the development process, and related recently that he has noticed big improvements during his recent tests.
“It’s definitely still a work in progress,” said Dixon about the new hybrid system. “I think the last few iterations have been a big jump forward.
“I think there’s a big relevance for technology that is key for our manufacturers, right, and what they do on a global kind of scale, especially what cars they produce for Honda. The hybrid situation is very big for them. I know they’ve put a lot of effort into it. The same with IndyCar. It’s something that they’ve committed to.
“I think it was kind of iffy for a period of time there for [implementation] next year. The last test went really well at Sebring. Logged a lot of miles. October, November, December, even in January with a lot more cars running it.
“The technology is pretty cool. It’s not our usual systems that I think we’ve seen in IMSA or other formulas. I hope they stick to not going automated, that it’s really on a driver input factor, which I think will spice up our racing, as well.
“I think it’s heading in the right direction. We’ll have to see once we get closer to the time. There’s a lot of effort that’s brought to this and it’s cool to see the tech they’re bringing it.”
IndyCar initially planned to introduce the hybrid systems, along with a new 2.4-liter engine, for the 2023 season, but development issues combined with pandemic-related supply chain problems forced a delay.
Development of the larger engine was paused while efforts were concentrated on getting the hybrid components race ready.
With testing becoming more frequent, and less secretive, as time goes on, fans of the sport have been pleased to note that the engine noise remains unchanged with the new components.
That particular point is another positive in Dixon’s mind, who understands that sound plays a crucial role in the entertainment factor.
“Yeah, for sure,” continued Dixon. “I’m passionate about cars that sound like race cars. That is definitely prominent for IndyCar’s future.
“Again, hopefully they spotlight the technology, too. I think it’s definitely different from what we’ve seen in other formulas.”
