Ferrari concluded the 2026 Formula 1 pre-season testing in Bahrain with Charles Leclerc setting the fastest lap of the second session, but a number of F1 engineers are now raising questions about the Scuderia’s small turbocharger design.
Leclerc recorded a 1:31.922 on the final day of testing, finishing 0.879 seconds ahead of McLaren’s Lando Norris. While the Monegasque driver’s pace was eye-catching, experts in the paddock caution that single-lap times during pre-season testing can be misleading, given the unknown variables such as fuel loads, engine modes, and tire programs that teams choose for their final sessions.
What many engineers are paying closer attention to is race pace and overall balance. Craig Slater reported after discussions with several F1 engineers in Bahrain that Ferrari currently look to be only the third-strongest team entering the 2026 season, behind Mercedes and McLaren, despite their headline-grabbing lap times.
Small turbo on Ferrari SF-26 could compromise performance at power-sensitive tracks
Ferrari have designed their new V6 power unit with a smaller turbo to mitigate the challenges of turbo lag that some rival teams have faced in previous seasons, particularly after the 2026 regulation changes removed the MGU-H component. This smaller turbo has allowed Ferrari to achieve exceptionally rapid race starts during testing, giving both Charles Leclerc and Lewis Hamilton a clear advantage off the line.
However, engineers are concerned that the small turbo could compromise top-end power on circuits that demand sustained engine output. Tracks like Monza, Spa-Francorchamps, Silverstone, and even the season-opening Albert Park in Australia could expose limitations in Ferrari’s 2026 power unit.
Craig Slater explained on Sky Sports News that while Ferrari’s design is excellent for rapid acceleration at race starts, it may create a performance deficit in power-sensitive sectors, potentially affecting their competitiveness across certain circuits. He emphasized that while the turbo provides strong initial bursts, managing longer straights and high-speed corners might reveal weaknesses compared to rivals Mercedes.
Mercedes tipped as the team to beat in 2026
According to paddock feedback collected by Craig Slater, there is a growing consensus that Mercedes will be the team to beat heading into the Australian Grand Prix. Many teams believe that the strength of the Mercedes engine gives McLaren an edge in both qualifying pace and race performance. Ferrari and Red Bull are expected to remain competitive, but there is caution over the SF-26’s reliability and power delivery in high-demand scenarios.
The Sky Sport News’ F1 presenter also noted that the 2026 Formula 1 campaign is likely to see a split in competitiveness, with a “big four” of Mercedes, McLaren, Ferrari, and Red Bull clearly ahead, while Alpine and Haas battle for best-of-the-rest positions. Williams is expected to sit just behind this group, with Cadillac and Aston Martin rounding out the midfield and lower midfield pack.
Slater concluded that, based on conversations with engineers and team insiders with direct access to GPS telemetry and race simulations, circuit-specific performance will play a major role in 2026. While Mercedes appears slightly ahead at the end of pre-season testing, the real test will come when the F1 teams face the opening race at Albert Park, as well as the other power-sensitive tracks that could challenge Ferrari’s small turbo strategy.
For Charles Leclerc and Lewis Hamilton, the focus will now shift to extracting consistent race pace from the SF-26 while addressing the potential trade-offs introduced by their innovative turbo design.
