McLaren Prepare Major Car Upgrade as Belgian and Hungarian Grands Prix Could Shape Title Fight

McLaren are hoping to revive their 2026 Formula 1 campaign after confirming a series of technical updates across the upcoming Belgian and Hungarian Grands Prix, with a substantial upgrade package scheduled to arrive before the sport enters its summer break.

The reigning Constructors’ Champions have endured a difficult title defence, slipping 154 points behind Mercedes after the opening nine rounds of the season. Despite entering the year among the favourites, McLaren have managed just one podium finish over the past five races, with Lando Norris claiming third place at the Spanish Grand Prix in Barcelona.

The team will begin its latest development phase at this weekend’s Belgian Grand Prix at Spa-Francorchamps by introducing a revised rear wing, which will be evaluated during Friday’s practice sessions. Both Norris and Oscar Piastri will also receive Mercedes-AMG High Performance Powertrains’ third internal combustion engine (ICE) of the campaign, featuring updated specifications designed to improve long-term reliability.

The latest power unit specification was first introduced by the Mercedes works team at the Austrian Grand Prix before being rolled out to customer teams at Silverstone. McLaren hopes the revised package will provide a more dependable platform during the second half of the season as reliability becomes increasingly important in the championship battle.

However, the team’s biggest expectations are reserved for next week’s Hungarian Grand Prix, where engineers will introduce what McLaren has described as a “significant upgrade package” aimed at unlocking the full potential of the MCL40.

The Woking-based outfit acknowledged that Belgium marks an important step in its development programme, but the more comprehensive aerodynamic revisions planned for Budapest are expected to have a greater impact on outright performance.

McLaren technical director of applied engineering Neil Houldey cautioned against expecting an immediate turnaround at Spa despite the new components.

He explained that while the latest rear wing should deliver a modest performance gain, the team remains realistic following a challenging British Grand Prix, where pure pace proved to be a weakness. Houldey stressed that the Belgian weekend is unlikely to produce a dramatic shift in competitiveness.

The timing of McLaren’s upgrades could prove crucial. Spa-Francorchamps and the Hungaroring present vastly different technical challenges, with Belgium rewarding straight-line speed and aerodynamic efficiency, while Hungary demands maximum downforce and consistent cornering performance. Strong results across both circuits would provide valuable momentum before Formula 1’s four-week summer shutdown.

Meanwhile, championship leaders Mercedes are approaching the double-header with mixed emotions. Although George Russell and Kimi Antonelli have helped establish the Silver Arrows at the top of both championships, reliability concerns have prevented the team from fully capitalising on its pace.

Antonelli has suffered two pointless finishes in his last three outings after retiring with an engine failure in Spain and later losing a potential victory challenge at Silverstone because of a wheel-guard failure. Russell also retired while leading the Canadian Grand Prix earlier in the season due to another engine-related issue.

Mercedes team principal Toto Wolff admitted the team has left valuable points on the table despite consistently fielding one of the fastest cars on the grid.

He emphasised that while Mercedes possesses the performance required to compete for victories, reliability failures have undermined its championship campaign. Wolff insisted that converting speed into consistent finishes must become the team’s priority heading into Belgium and Hungary.

With only two races remaining before the summer break, both Mercedes and McLaren view the upcoming double-header as a defining period. Mercedes aim to strengthen their championship advantage through flawless execution, while McLaren hope their latest development programme can reignite their campaign and close the gap to the front before Formula 1 returns for the Dutch Grand Prix in late August.
