Hamilton Raises 'GP2' Concern as Mercedes Engine Trick Dominates Testing Talk
The first day of F1 pre-season testing was dominated by Lewis Hamilton's comments that the new cars feel slower than F2 machines and a growing controversy over a clever Mercedes engine trick. While Lando Norris set the fastest time, discussions centered on technical regulations and early reliability issues for Red Bull and Mercedes.
Lewis Hamilton has voiced concerns that the latest generation of F1 cars can "feel" slower than F2 machinery, even as Mercedes finds itself at the center of a paddock debate over a clever and controversial engine trick. The first day of pre-season testing in Bahrain saw Lando Norris top the timesheets, but the underlying narrative was dominated by technical intrigue and early reliability scares.
Why it matters:
The combination of a seven-time champion questioning the visceral sensation of the new cars and a major engine regulation loophole debate threatens to overshadow the on-track running. How the FIA handles the Mercedes engine allegation could set a precedent for technical governance, while teams' early reliability issues provide the first real clues about the competitive order taking shape for 2026.
The details:
- Hamilton's Sensory Feedback: Despite calling the 2026 cars "more fun to drive," Lewis Hamilton remarked they can subjectively feel slower than the GP2/F2 cars he drove earlier in his career, highlighting a disconnect between data and driver sensation.
- The Mercedes Engine Debate: Mercedes has attracted scrutiny for its power unit's reported ability to run an 18:1 compression ratio when hot, seemingly circumventing the 16:1 regulatory limit. The trick is understood to be a clever interpretation of the new PU rules.
- Paddock Reaction: Aston Martin's Adrian Newey admitted he is "biased" in judging the trick, while Williams boss James Vowles warned of "punishing" consequences if a mid-regulation change is made, arguing it would unfairly penalize Mercedes and its customer teams for their ingenuity.
- Testing Day 1 Results: McLaren's Lando Norris set the fastest lap in Bahrain. World Champion Max Verstappen's consistent long-run pace for Red Bull was noted as a major statement of intent, despite the team facing a separate engine issue.
- Early Reliability Problems: Red Bull's new RBPT-Ford power unit experienced its first major problem, sidelining Racing Bulls rookie Arvid Lindblad for the afternoon session. Mercedes also had a "difficult" day, with George Russell citing ongoing balance and correlation issues.
What's next:
All eyes will remain on the Sakhir circuit as testing continues, with teams gathering critical data on performance and reliability. The formal protest window regarding the Mercedes engine interpretation will be a key off-track focus. The FIA's response, or lack thereof, will signal how flexibly the new power unit regulations will be enforced and could define early-season competitive advantages.
