2026 F1 Cars Show Surprising Reliability and New Driving Demands in Barcelona Shakedown

After the private runs, teams face an energy‑management learning curve and an unresolved engine‑measurement dispute as they prepare for Bahrain testing.

Overview

  • Mercedes topped the mileage in Barcelona and described the field’s reliability as “astonishing,” suggesting a sturdier baseline than many expected for the new rules.
  • Drivers report altered techniques with the 2026 package, including downshifts on straights and lift‑and‑coast even on qualifying laps, while Lewis Hamilton says the cars feel more enjoyable to drive.
  • Overtaking remains uncertain after Haas drivers found following more difficult and the new Overtake mode not yet a clear fix in initial runs.
  • Early impressions point to Mercedes, Ferrari, Red Bull and McLaren setting the pace, while Audi suffered repeated failures that left what Mattia Binotto called a “very, very long list” of issues to address.
  • Several manufacturers raised engine‑compression measurement concerns with the FIA regarding Mercedes/Red Bull Powertrains; Toto Wolff insists compliance as teams target Bahrain tests on 11–13 and 18–20 February to validate upgrades.
