The introduction of the 2026 Formula 1 technical regulations brought the sport a ground-up reboot, fundamentally altering how downforce is generated and power is deployed. While some paddock chatter has recently suggested the current generation of machinery might be slightly easier to push to the absolute limit in qualifying because of smaller teammate gaps, McLaren Team Principal Andrea Stella vehemently disagrees.
Following the Sprint at the Dutch Grand Prix, Stella told the media that the current cars are actually proving to be exceptionally demanding, unpredictable, and punishing for drivers who fail to find the perfect rhythm.
When asked about the current handling characteristics, Stella made it clear that McLaren’s internal feedback paints a picture of extreme difficulty. He pointed directly to the massive reduction in aerodynamic load as a primary culprit.
“I think these cars are classified by both our drivers, I don’t know about the others, as difficult cars to drive,” Stella told the media. He explained that when a driver is slightly on the back foot, the time penalty can be massive because they are battling severe instability “in the corners because of the low grip, much less downforce, smaller tires.”
His assessment perfectly aligns with the mechanical realities of the 2026 rulebook. In an effort to reduce drag and dirty air, the FIA significantly shrank the floor tunnels, stripping the cars of an estimated 15 to 30 percent of their overall downforce. Furthermore, the transition to narrower 18-inch rubber—with the front tires shrinking by 25 millimeters and the rears by 30 millimeters—has left drivers with far less mechanical grip to lean on through tight complexes like Zandvoort’s middle sector.
The Hybrid Deployment NightmareThe challenge of the 2026 regulations is not purely aerodynamic. The completely redesigned hybrid power units, which now rely on an approximate 50-50 split between internal combustion and a massively upgraded 350kW MGU-K electric motor, require intense manual energy management.
Stella highlighted that the complexities of this electrical deployment are wreaking havoc on the drivers’ spatial awareness and braking zones.

He added that drivers are also dealing with “the frustrating element that you go on power early in high speed and now you are losing deployment later.” While Stella noted that both the engineers and drivers are gradually becoming more familiar with the power unit’s unique behaviors compared to the start of the season, the raw unpredictability remains a massive hurdle.
A Stark Contrast to the Ground Effect EraWhen directly comparing the current machinery to the highly refined cars of the previous 2022-2025 regulatory cycle, Stella believes the challenge has undoubtedly increased.
He told the media that despite everything happening much faster in the previous generation of cars, they featured “much, much more load aerodynamically and much more grip from the tires, and it was easier” because drivers generally only had one primary physical force to cope with.
Today, drivers are forced to juggle Active Aero modes, intense energy harvesting, and cars that are highly sensitive to sudden wind changes—factors that completely ruined clean qualifying laps for much of the grid in Hungary and Zandvoort.
“But this year you have to get used to adapt to the fact that you can have any kind of problem because the car slides a lot,” Stella concluded.
