McLaren has made a surprising driver change ahead of the 2026 Hungarian Grand Prix, temporarily replacing Oscar Piastri for the opening Free Practice session with highly rated junior Leandro Fornaroli. While the move may appear dramatic at first glance, it is part of Formula 1’s mandatory young driver programme and comes at a critical stage of the season as McLaren introduces a significant upgrade package before the summer break.
The timing, however, has drawn attention because Piastri is fighting to revive his championship campaign after another frustrating weekend in Belgium. With only a handful of races remaining before the title battle reaches its decisive phase, every lap of practice carries enormous value.
WHY MCLAREN HAS SIDELINED PIASTRI FOR FP1
Oscar Piastri will step aside only for the first practice session at the Hungaroring, allowing Formula 2 and Formula 3 champion Leandro Fornaroli to complete McLaren’s latest mandatory rookie outing.
Formula 1 regulations require every team to hand at least four Free Practice sessions each season to drivers with limited Grand Prix experience. Fornaroli has already driven McLaren’s car once this year in Barcelona after replacing Lando Norris during FP1, and the Italian now receives another valuable opportunity to showcase his speed.
Piastri will return for Free Practice 2 and participate in the remainder of the Hungarian Grand Prix weekend.
Although the move is routine from a regulatory standpoint, the circumstances surrounding it make it especially significant.
MCLAREN’S MAJOR UPGRADE PACKAGE ARRIVES AT A CRUCIAL MOMENT
The Hungarian Grand Prix marks McLaren’s final opportunity to introduce meaningful performance upgrades before Formula 1 enters its summer shutdown.
Among the developments expected on the MCL40 are a revised floor, aerodynamic refinements, and updates to the team’s rear-wing configuration. These components could play a major role in improving the car’s competitiveness over the second half of the season.
Allowing Fornaroli to collect valuable engineering data during FP1 provides McLaren with another perspective on how the new package performs under real track conditions.
For the engineers, this isn’t simply about rewarding a young talent—it is another opportunity to gather information that could shape the team’s championship ambitions.
PIASTRI FACES AN EXTRA CHALLENGE
While the rookie session benefits McLaren’s long-term development programme, it creates a small disadvantage for Piastri.
Because Fornaroli will drive during the opening hour of practice, Piastri loses valuable track time needed to understand the behaviour of the upgraded car. Instead of building confidence across two Friday sessions, the Australian must accelerate his learning during FP2 before qualifying preparations begin.
That challenge becomes even greater considering the pressure already surrounding his season.
Piastri finished fifth at the Belgian Grand Prix after surviving contact with Ferrari’s Charles Leclerc during the race, but the result did little to improve his championship position. He currently sits sixth in the Drivers’ Championship, only one point ahead of four-time world champion Max Verstappen.
Every competitive session now matters.
FORNAROLI CONTINUES HIS RAPID RISE
Leandro Fornaroli has quietly become one of the most promising young drivers in motorsport.
Winning consecutive Formula 3 and Formula 2 championships established him as one of the strongest talents in McLaren’s development programme. His previous FP1 outing in Spain impressed team engineers sufficiently to earn another opportunity in Hungary.
The 21-year-old has spent recent weeks preparing extensively in McLaren’s simulator at Woking to maximise every minute behind the wheel.
Fornaroli described the opportunity as another important step in his development, emphasizing that every session helps him build confidence while contributing meaningful feedback to the engineering team.
Strong performances during practice sessions often influence future Formula 1 opportunities, making Friday another important audition for the Italian.
CAN MCLAREN’S UPGRADES REVIVE THEIR SEASON?
McLaren entered the 2026 campaign with genuine title aspirations but has struggled to consistently challenge Mercedes throughout the season.
While Lando Norris has shown flashes of strong pace, reliability concerns and the unpredictable behaviour of the new power-unit regulations have prevented McLaren from maintaining sustained pressure at the front.
Piastri has also endured an inconsistent campaign, with several promising weekends compromised by incidents, strategy setbacks, or performance limitations.
If the Hungarian upgrade package delivers the expected gains, McLaren could emerge as a far more dangerous contender during the final stretch of the championship.
THE CHAMPIONSHIP BATTLE CONTINUES TO TIGHTEN
As McLaren searches for answers, Mercedes continues to control both championship races.
Teenage sensation Andrea Kimi Antonelli arrives in Hungary seeking his seventh victory in just 11 races this season. His remarkable consistency has opened a 46-point lead over Lewis Hamilton, while teammate George Russell remains within striking distance despite recent setbacks.
For McLaren, Ferrari, and Red Bull, the Hungarian Grand Prix represents one final opportunity to build momentum before Formula 1 pauses for its summer break.
A successful weekend could redefine expectations heading into the decisive second half of the campaign.
WHY THIS DECISION MATTERS BEYOND HUNGARY
Although Piastri’s temporary replacement is purely procedural, it highlights two important realities within modern Formula 1.
First, teams are placing increasing emphasis on developing future stars through meaningful practice opportunities rather than limiting rookies to simulator work. Second, every practice session has become a strategic tool for gathering performance data, particularly when major upgrades are introduced.
McLaren hopes that sacrificing one hour of Piastri’s preparation will ultimately strengthen its understanding of the MCL40 and improve its chances over the remainder of the season.
Whether those upgrades can transform McLaren from occasional podium challengers into genuine race winners may become clear as soon as qualifying begins in Budapest.
