Isack Hadjar completed 107 laps on his first full day with Red Bull’s in-house Ford power unit, expressing surprise at the reliability shown during Monday’s Barcelona shakedown. The French rookie topped the timesheets for Red Bull Racing with a 1:18.159, though lap times remain largely irrelevant at this early stage. Both Red Bull teams focused purely on building mileage with the new DM01 engine, named in tribute to Dietrich Mateschitz, with initial feedback suggesting a solid foundation despite expected teething issues.
Red Bull’s first serious engine test exceeds expectations
The Circuit de Barcelona-Catalunya marked the first substantial workout for Red Bull Ford Powertrains following a limited filming day at Imola. Hadjar, making his debut with the full RB21 package, expressed cautious optimism about the power unit’s performance during his maiden outing.
“It was pretty productive. Surprisingly we managed to do a lot more laps than expected,” Hadjar explained after stepping out of the car. The Frenchman’s 107 laps represented a significant achievement for a completely new power unit on its first proper test day. Everything went quite smoothly with only minor issues arising, particularly impressive considering Red Bull Ford Powertrains are running their own engine for the first time since Honda’s departure.
The RB F1 Team driver acknowledged the challenge of developing an entirely new power unit from scratch. Ford Performance director Mark Rushbrook had previously indicated that the final development phase concentrated heavily on driveability rather than outright performance, a decision that appears vindicated by Monday’s smooth running.
Driveability assessment shows promising early signs
Beyond pure reliability, Hadjar’s feedback on the engine’s driveability characteristics provided Red Bull engineers with crucial early data. The rookie’s previous experience with Honda power units gave him a useful reference point for comparison.
“Honestly, it was pretty decent for a first day. It doesn’t feel too far off from what I’m used to based on my first season,” Hadjar noted. The upshifts and downshifts functioned adequately, though the French driver acknowledged several areas requiring refinement before the season opener in Melbourne.
This driveability focus reflects lessons learned across the paddock about modern power unit development. Raw horsepower means little if drivers cannot deploy it effectively through corners or manage energy recovery systems smoothly. Red Bull’s decision to prioritise this aspect during final development phases suggests a mature approach to their ambitious in-house engine project.
The DM01 designation pays tribute to late Red Bull owner Dietrich Mateschitz, whose vision enabled the team’s power unit independence. Engineers face immense pressure to honour that legacy with a competitive product from the outset.
Lawson’s stoppage proves precautionary rather than problematic
Liam Lawson caused the third red flag of Monday’s session, stopping during a practice start just before the lunch interval. The New Zealander’s VCARB 03 accumulated 88 laps despite the interruption, with team engineers quickly clarifying the nature of his stoppage.
“The moment on the grid was nothing important. It was just related to some safety settings that we put in the car just to not damage anything as a precaution,” explained Mattia Spini, RB F1 Team’s chief race engineer. The conservative approach reflects the team’s priority of preserving components during these critical early running phases.
Lawson himself downplayed any concerns about the power unit’s reliability. “The only issues we really had were safety precautions, not any actual issues. On the power unit side, it’s been very, very good so far,” the Red Bull Racing driver confirmed. His assessment aligned with Hadjar’s positive feedback, suggesting both RB21 chassis were experiencing similar performance characteristics.
The stoppage allowed engineers to recalibrate safety parameters for the afternoon session, which proceeded without further interruption. This type of conservative systems management typically characterises shakedown running, where teams deliberately err on the side of caution to protect expensive components.
Engineering relationship between teams shows early strength
Spini’s comments highlighted the collaborative atmosphere between Red Bull Racing, RB F1 Team, and Red Bull Powertrains. The integration of a new power unit manufacturer into existing team structures often creates friction, but early indications suggest smooth cooperation.
“The power unit is working fine. Again, it’s not perfect, but we didn’t expect it to be,” Spini acknowledged candidly. Red Bull Powertrains engineers demonstrated transparency about current limitations whilst maintaining open communication channels with both chassis teams.
“The engineers with us and in the factory, they are really open and honest. The relationship is really good between the two groups. Actually, we are almost the same team,” Spini added. This organisational cohesion could prove crucial as inevitable development challenges emerge during the season.
The chief race engineer confirmed plans to fine-tune the power unit before Melbourne, suggesting Red Bull identified specific areas for improvement during Monday’s running. These adjustments will continue throughout the remaining Barcelona days and intensify during Bahrain’s official pre-season testing.
Performance assessment delayed until Bahrain testing
Both Red Bull teams maintained consistent messaging about their Barcelona objectives. Reliability remains the absolute priority during shakedown running, with performance evaluation scheduled for Bahrain’s official test sessions.
“Assessing the performance is not going to be the primary goal of this test. We are going to focus on performance more in Bahrain,” Spini confirmed. The approach mirrors strategies adopted by rival teams, all prioritising mileage accumulation over headline lap times.
Hadjar’s fastest time of 1:18.159 therefore carries minimal significance. Teams run different fuel loads, tyre compounds, and engine modes during shakedown sessions, making direct performance comparisons meaningless. The true pecking order will only emerge during Bahrain’s final pre-season test week.
Red Bull’s focus on building confidence with the new package makes strategic sense. Max Verstappen remained absent on Monday but will join testing later this week, providing crucial feedback from a four-time world champion’s perspective. His input could identify subtleties that less experienced drivers might miss.
Remaining Barcelona running targets mileage accumulation
Each team receives three days of shakedown running across the five-day Barcelona window. Red Bull Racing and RB F1 Team strategically chose Monday as their opening session, gaining a data advantage whilst McLaren and Ferrari focused on workshop preparation.
The remaining two days will follow similar reliability-focused programmes. Engineers want maximum mileage to stress-test components and identify potential failure points before the season begins. Every lap completed in testing prevents potential retirements during competitive sessions worth championship points.
Red Bull Powertrains face immense scrutiny as they attempt to match Mercedes, Ferrari, and Honda’s established power unit programmes. Monday’s smooth running provided an encouraging foundation, but sustained reliability across a 24-race season represents a far greater challenge. The Barcelona shakedown offers just a glimpse of the development journey ahead.
