Penske believes it missed a clear opportunity to give the new Acura ARX-05 a victory on its debut in last weekend's Daytona 24 Hours.
Ricky Taylor, who shared the #7 Acura Daytona Prototype international with Helio Castroneves and Graham Rahal, described the opening round of this year's IMSA SportsCar Championship as "one that got away" for Penske.
Both Penske Acuras were in the fight on Sunday morning with the pair of Action Express Cadillac DPi-V.Rs that finished one-two in the race before encountering problems.
The #6 Acura driven by Juan Pablo Montoya, Dane Cameron and Simon Pagenaud was hit by electrical problems that were resolved by changing the alternator in the 16th hour and the #7 sustained bodywork damage after an incident after the final safety car in hour 18.
"It feels like one that got away given the problems that the Cadillacs had at the end, because we had no mechanical issues at all," Taylor told Autosport.
"It was an amazing race, with a relentless pace, so it would have been interesting to see what would have happened if we had been able to race hard to the end."
Cameron used similar language to Taylor to describe the disappointment of the Penske, which notched up ninth and 10th-place finishes with its two cars after the delays.
"It feels like one potentially got away from us here and it would have been nice to have been in a fight for the win at the end," he said.
"We know we have a strong Acura ARX-05 and we are gearing up to make a run at the championship.
"While one race may have gotten away, we still have a lot of big ticket races to win this year, along with the championship." Taylor agreed that either of the two Penske Acuras could have won but for their problems.
"It was kind of flip-flopping back and forth between our two cars," he explained.
"Our car was really strong during the night and the other cars was perhaps a little better during the day."
The Action Express cars both encountered overheating problems in the closing stages and had to back off.
That allowed the Core Autosport ORECA-Gibson 07 to come back from a deficit of six laps on the leaders to finish only 90 seconds behind.
