Chevrolet and Honda completed a three-day test Wednesday of the 2.4-liter, twin-turbocharged V-6 engine that is slated to bring hybrid technology to the NTT IndyCar Series in the 2024 season.

The manufacturers turned hundreds of laps on the Indianapolis Motor Speedway road course in a test that was extended a day after cold weather precluded running Monday morning.

According to a release, Chevrolet logged more than 600 miles on the 13-turn, 2.6-mile layout with Team Penske series champions Josef Newgarden (Monday) and Will Power (Tuesday-Wednesday). The engine was missing its energy recovery system because of supply-chain issues that also have caused IndyCar to delay its implementation by a year (after already having been delayed a year by the pandemic).

“We’ve had a very successful and productive three days with the new Chevrolet 2.4L IndyCar engine,” Chevrolet’s IndyCar engineering program manager Rob Buckner said in a release. “This was a big milestone as we have progressed from the initial concept of the 2.4L design a few years ago and running extensively on the dyno to installing the engine into a car and now the landmark event of turning our first laps.”

Honda Performance Development also tested the engine’s internal combustion component over three days with six-time series champion Scott Dixon and Chip Ganassi Racing in the first of multiple tests for the next-generation hybrid.

HPD president and technical director David Salters said in a release that the test was successful “but there are many more steps to take before the full, hybrid power unit debuts in 2024.

“The engine ran well throughout the three days, and we completed all planned test items, thanks to Chip Ganassi Racing and Scott Dixon,” Salters said. “The car ran flawlessly with great collaboration and feedback, and we learned a lot. Props to the extremely well-informed fans out there in social media land who noticed a deeper gnarly tone from our new HPD Indycar racing engine.  It is an entirely new design from HPD, and it certainly grabs your attention, not bad for a bio-fueled, super-efficient racing engine.

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

Power said he made 150 laps with the 2.4-liter engine.

“It was clear immediately that Chevy has put a lot of work into this already,” the 2018 Indy 500 winner said. “It will obviously continue to get better and better. I was impressed with the power of the engine throughout the day.

“I’m very excited about this addition to the series and can’t wait to continue to help develop it.”

More team testing was scheduled at IMS for Thursday and Friday but was canceled because of inclement weather.

IMSA WeatherTech SportsCar championship contender Tom Blomqvist put the Meyer Shank Racing Acura at the front of the starting lineup for the Motul Petit Le Mans at Michelin Road Atlanta.

Blomqvist turned a 1-minute, 8.55-second lap on the 2.54-mile circuit Friday to capture his third pole position for MSR this season. Earl Bamber qualified second in the No. 02 Cadillac for Chip Ganassi Racing.

Ricky Taylor was third in the No. 10 Acura of Wayne Taylor Racing, which enters Saturday’s season finale with a 19-point lead over the No. 60 of Blomqvist and Oliver Jarvis (who will be joined by Helio Castroneves) for the 10-hour race.

With the pole, MSR sliced the deficit to 14 points behind WTR, which will field the trio of Taylor, Filipe Albuquerque and Brendon Hartley in Saturday’s race.

“We really needed to put the car in this kind of position,” Blomqvist said. “It makes our life a little less stressful tomorrow. It would have given the No. 10 a bit more breathing space. It’s going to be a proper dogfight tomorrow. The guys gave me such a great car. It’s been fantastic this week so far, and it really came alive. I’m hugely thankful to the boys and girls at MSR for giving me the wagon today to execute my job.

“That was a big effort from me. I knew how important it was. It’s just awesome for the guys to give them some sort of reward as well. It’s always nice to be quick. If you do the pole, you know you’ve got a quick car.”

Though WTR has a series-leading four victories with the No. 10, MSR won the Rolex 24 at Daytona and has five runner-up finishes along with its three poles.

The strong performances of the ARX-05s ensure that an Acura will win the final championship in IMSA’s premier Daytona Prototype international (DPi) division, which is being rebranded as Grand Touring Prototype in the move to LMDh cars next season.

Taylor qualified third despite sliding into the Turn 5 gravel during the closing minutes of qualifying while pushing to gain points.

“Qualifying was important for points,” Taylor said. “Going into it, if we outqualified the No. 60 Meyer Shank Acura, they had a lot to lose in terms of championship points. So, we were trying to increase the gap over 20 points which would’ve made a big difference for tomorrow. We would have loved to get the pole and qualify ahead of the No. 60, but in the scheme of the points, it didn’t change a whole lot. I’m feeling good since it’s such a long race, and the No. 10 Konica Minolta Acura team does such a good job strategizing and putting us in a good position.

“I’m very confident in our lineup and our team compared to them over the course of 10 hours. I’d put my two teammates up against those guys any day. I think we are all feeling optimistic and strong for tomorrow.”

In other divisions, PR1 Mathiasen Motorsports (LMP2), Riley Motorsports (LMP3), VasserSullivan (GTD Pro) and Paul Miller Racing (GTD) captured pole positions.

The broadcast of the 10-hour race will begin Saturday at 12:10-3 p.m. ET on NBC, moving at 7 p.m. to USA Network. Peacock will have flag-to-flag coverage.
