Formula 1 is conducting its initial shakedown for the 2026 regulations at the Circuit de Barcelona-Catalunya this week, deliberately kept from public view to prioritize operational checks over spectacle. Teams aim to verify the reliability of new power units, active aerodynamics, and other innovations without the pressure of live broadcasts. While fans express frustration, officials emphasize the event's focus on fundamentals amid challenging weather.
The 2026 Formula 1 season introduces sweeping changes to cars and engines, prompting a cautious approach to the inaugural on-track session. Framed officially as a shakedown rather than a full test, this five-day event at Barcelona allows teams to run for only three days each, focusing on basic reliability rather than performance hierarchies. Unfavourable weather—rain and temperatures in the teens—will limit running times, with teams scrutinizing forecasts to select optimal days.
Several teams have already conducted limited on-track shakedowns, but feedback highlights a desire for more mileage. Most fell short of the 200km cap due to poor conditions, not technical issues. Unlike the 2014 hybrid era, where Renault struggled and embarrassment ensued, much of the 2026 technology builds on proven elements. The MGU-H component has been eliminated, shifting emphasis to a more powerful MGU-K, which demands new driving techniques like increased lift-and-coast through corners.
Key areas under scrutiny include the new power units' reliability beyond dyno tests, sealed fuel flow sensors resistant to sustainable e-fuels, and active aerodynamics' effects on car balance during mode transitions. FIA single-seater director Nikolas Tombazis noted at the Autosport Business Exchange in London that there is “quite a lot of flexibility” in energy deployment adjustments, requiring real-world data for calibration.
Development strategies vary: McLaren delayed its final build for maturity, planning to run from Tuesday at the earliest, while Alpine targets Monday with an early-season upgrade in mind. Coverage is minimal—a small F1 TV crew for soft interviews and shared imagery—avoiding full broadcasts to manage expectations and prevent speculation during garage-heavy sessions. This approach underscores F1's business priorities in navigating regulatory transitions, countering perceptions of secrecy driven by PR fears.
