McLaren believes tyre behaviour on Madring’s brand-new asphalt will be the biggest unknown heading into the 2026 Madrid Grand Prix, despite already having extensive simulation data for the circuit. The team will also introduce minor aerodynamic updates to the MCL40, but Technical Director Mark Temple believes Friday practice will be crucial in understanding a variable that simulations cannot fully reproduce.
Madrid represents a step into the unknown for the entire Formula 1 grid. McLaren has already gathered significant information about the layout, energy management and aerodynamic requirements of the new Spanish circuit, yet the way the tyres interact with the fresh surface could have a major influence on setup choices for qualifying and the race.
McLaren identifies tyre behaviour as Madrid’s biggest unknown
“Heading to a completely new circuit in Madrid brings both immense opportunity and risk. We have solid simulation data regarding the track layout, energy deployment and aerodynamic demands, but the biggest variable remains tyre behaviour on this new asphalt,” Mark Temple explained.
McLaren, like every other team, will therefore need to understand the circuit’s evolution, grip level and surface characteristics as quickly as possible once the cars leave the garage on Friday. Those findings could shape the direction of the MCL40 setup for the rest of the weekend, especially with the gaps between the leading teams currently so small.
The uncertainty also makes adaptability particularly important. Even the most detailed pre-event simulations cannot completely reproduce how a new racing surface will develop as Formula 1 cars lay down rubber and conditions evolve across the weekend.
Madring demands braking stability and precise kerb use
The new Madrid circuit also features an unusual combination of characteristics. According to Temple, strong braking stability will be essential, including during phases when the driver is simultaneously turning the car into a corner.
McLaren will also need the MCL40 to handle kerbs effectively through the slower sections without compromising performance through several important high-speed passages.
“The track is tight and demands exceptional braking stability, especially while cornering, as well as precision when using the kerbs in the slow-speed sections and through a few crucial high-speed corners,” the British engineer added.
Those characteristics create an interesting test for a McLaren package that has shown particularly strong performance in faster corners during recent races, while slower sections have remained an area where the team has continued searching for improvements.
McLaren brings minor MCL40 aerodynamic updates to Madrid
McLaren will arrive in Madrid with further minor aerodynamic developments for the MCL40, continuing the refinement programme that has helped the team move closer to Mercedes and Ferrari in recent Grands Prix.
The latest changes follow a period of significant development for the Woking squad, with further work already planned as part of McLaren’s wider MCL40 upgrade programme.
One component that will not appear in Madrid is the H-Wing introduced at Monza. That solution was specifically designed around the efficiency demands of the ultra-fast Italian circuit and is not considered suitable for Madring’s very different characteristics.
Temple nevertheless remains cautious about how much the incremental developments can change the competitive picture.
“Our ongoing aerodynamic and mechanical refinements continue to move us forward step by step, but the margins between the top teams remain very small.”
McLaren says adapting fastest could decide Madrid weekend
More than the upgrades themselves, McLaren believes success in Madrid could depend on how quickly the team reacts to the information collected from the opening laps.
With no previous Formula 1 race weekend at Madring to provide historical data, the first practice sessions will take on greater importance than usual. Engineers will need to compare real-world behaviour with their simulations and adapt the car accordingly as grip levels and track conditions become clearer.
“New venues reward the teams that adapt fastest. Our objective is to progressively build confidence and performance through every session, in order to achieve the maximum result when it really matters on Sunday,” Temple concluded.
McLaren therefore heads into Madrid with a strong understanding of the theoretical demands of the new circuit but one significant question still unanswered. The MCL40 will receive further refinements, yet the way the tyres behave on Madring’s new asphalt could ultimately prove more important than any individual aerodynamic component.
