“So the development will be to achieve the maximum aerodynamic efficiency, to get the car to interact with the tyres as well as possible, mechanical grip with the suspensions, and it will also go in the power unit.”
The power unit element represents one of the biggest changes for 2026, and Stella highlighted the role the drivers will play this year in dealing with the engines will be key.
“This year more than ever, I think the power unit will depend on how the drivers interact with the power units,” he said. ” So lots of areas to develop, lots of areas to make the difference with.”
Asked whether Norris and Piastri would master the new machinery immediately, Stella predicted continuous evolution.
“I think the learning curve will involve this area as well, you know, like interacting with the power unit and this is also because we engineers or all the engineers, HPP, McLaren, all teams, we learn more and we’ll develop the power unit so the drivers will have to stay in tune with this development.”
The first pre-season test runs from 11-13 February at the Bahrain International Circuit, with a second three-day test following on 18-20 February before the season begins in Melbourne on 6-8 March.
