McLaren Teases 'Entirely New' Car for Miami Grand Prix

McLaren is targeting a significant performance leap with a major upgrade package for the Miami Grand Prix, aiming to replicate the transformative success of its 2023 car. Team Principal Andrea Stella confirmed the MCL40 will be "entirely new" aerodynamically for the North American races, a plan accelerated by the early-season calendar changes that freed up development time.

Why it matters:

After a solid but unspectacular start to the season, McLaren is betting big on a single, comprehensive upgrade package to close the gap to Mercedes and Ferrari. This mirrors their 2023 strategy, where a Miami-spec car launched them into consistent podium contention and ultimately the championship fight, proving the team's ability to execute dramatic in-season development turnarounds.

The Details:

• Team Principal Andrea Stella stated the plan was always to deliver a "completely new car from an aerodynamic point of view" for the North American leg of the season, encompassing Miami and the subsequent Canadian Grand Prix.
• The cancellation of the Bahrain and Saudi Arabian Grands Prix provided a crucial, uninterrupted development window. Stella acknowledged this helped McLaren and all rivals work "more streamlined towards upgrading the car."
• Despite the major changes, Stella tempered expectations, noting that competitors have had the same timeline. He framed Miami as a check on "who has been able to add more performance within the same time frame."
• The team recognizes it has "some performance to recover" relative to Mercedes and Ferrari, following a Japanese GP where the car showed decent pace but still finished behind the leading teams.

What's Next:

The Miami Grand Prix will serve as the first real-world test of McLaren's off-track development work and their capacity to adapt to the new 2026 regulations from a position of strength as reigning champions. Stella views the regulatory reset not as a disappointment but as a welcome challenge to measure the team's maturity and ability to generate new knowledge. Success in Miami could validate their off-season work and set the tone for their 2026 title defense, while a miss would signal a tough development battle ahead.
