From Catch-Up to Contender: How McLaren transformed the MCL40 in 2026

McLaren began the 2026 Formula 1 season as the reigning champions but faced challenges with their MCL40 car, which was not initially the fastest. Over the first half of the season, they implemented significant upgrades and improved their understanding of the new regulations and power unit, leading to a notable victory by Lando Norris at the Hungarian Grand Prix.

The development of the MCL40 has focused on gradual improvements rather than radical changes, with the team addressing issues such as weight management and drivability. They have also learned to optimize the performance of their Mercedes power units and the new tyres, aiming to enhance both the car's speed and the drivers' ability to extract maximum performance.
