Button finished 19th in the 2024 drivers championship, with his best result sixth at the Six Hours of Fuji race in September, while he was also ninth at Le Mans.
Despite missing one of the pre-season practice sessions due to a bout of bronchitis, Button said he has “got to grips reasonably quickly” with the new car.
There are also advantages to being in a manufacturer’s team which the 45-year-old believes will give Jota more of an edge this year.
“You feel the difference and I think it’s because when you have an issue you can work with the tools a lot more because it’s obviously all open,” Button said.
“Whereas last year we were limited on what we can actually do and certain things we just could not change because we weren’t allowed to.
“It’s what [Porsche] Penske basically chose and we went with it whereas here it’s a lot more open and there’s a lot more adjustability and things get done a lot quicker.
“I think it’s a lot easier to make progress and find comfort in the car.”
Last year was Button’s first full season of racing since 2019 when he competed in Japan’s Super GT Championship. While getting back into driving was not an issue, adjusting to the complex systems in the cars was the biggest learning curve.
“It’s not [a case of] you set it up and then you just drive it,” Button said.
“It was understanding the tools and they can make a massive difference to how the car feels and you can really benefit if you understand those tools.
“This year it’s been a lot easier. It’s obviously different systems but a lot of the stuff does the same.”
