Red Bull Racing’s strong recovery in the latter part of the 2025 Formula 1 season has boosted confidence within the team and among supporters of Max Verstappen. After facing challenges throughout the year, this resurgence has strengthened Verstappen’s belief that Red Bull is moving in the right direction as they prepare for the upcoming regulation overhaul in 2026, with a particular focus on their new power unit.
Despite winning the 2024 Drivers’ Championship, Verstappen and Red Bull struggled with pace compared to rivals McLaren and Ferrari. The start of 2025 did not improve significantly, but Verstappen’s exceptional performance in the final ten races nearly secured him a fifth straight title, missing out only by a narrow margin. These developments underline both the team’s resilience and the intense competitiveness of the field heading into 2026.
Insights from Barcelona Shakedown Hint at Red Bull’s Growing Engine Confidence
The Barcelona shakedown this year garnered attention as George Russell topped the lap count, sparking discussions about whether sheer mileage translates directly to on-track performance. During this period, speculation surrounded Verstappen’s future, with rumors suggesting a move to Mercedes, though he ultimately committed to Red Bull for another season under the guidance of Laurent Mekies.
The major question for 2026 centers on Red Bull Powertrains’ ability to produce a competitive and reliable first-ever Formula 1 power unit, particularly against powerhouses like Mercedes, Ferrari, Honda, and Audi. Esteemed journalist and broadcaster Nelson Valkenburg, speaking on the Nailing the Apex Podcast, shared insider views on Red Bull’s progress after the Barcelona tests.
Valkenburg explained that the team achieved significant mileage and grew steadily more confident with their new engine package over the course of the shakedown.
“Every time I spoke to them, they seemed more and more, let’s say, proud of what they’re achieving because let’s just not underestimate what they had to do here,”
he said. He highlighted the ambitious challenge Red Bull faced in building their own power unit in collaboration with Ford for the first time, stressing the importance of precise processes throughout development.
He further noted,
“I think Red Bull Powertrains can be incredibly proud.”
On performance, Valkenburg remarked that the new Red Bull looked competitive, placing it in a comparable bracket to others after the final day of testing. Despite some issues—Isack Hadjar experienced an off-track excursion, and Verstappen reportedly had one or two during the cold conditions—these are seen as typical teething problems.
“If it snaps away from you like that a couple of times in very cold conditions, as well, it could mean that the way the power is implemented and how you get it to your rear wheels could be a bit harsh.”
But that’s why you do this shakedown, and that’s the learning curve every team will have with these engines.

Ongoing Refinements Expected as Red Bull Prepares for Bahrain Test
One notably positive aspect of the Barcelona shakedown was the distance covered by both the Red Bull factory team and its affiliate, Racing Bulls. Compared to other new power unit manufacturers, Red Bull made a marked impression, outperforming Audi despite Aston Martin’s late arrival limiting Honda’s data gathering.
While the car’s outright speed remains encouraging, reliability has emerged as the primary focus for Red Bull as they aim to smooth out remaining ‘rough edges’ on their engine. This approach reflects a realistic prioritization typical of early development phases before race-ready form is achieved.
Looking ahead to the new season, if Mercedes manages to dominate with clear performance advantages, Verstappen and teammate Isack Hadjar may face difficult battles just to secure minor points finishes. Conversely, Red Bull is optimistic about fielding a package faster than teams like Alpine and Williams. Early indicators suggest the established big four—Mercedes, Ferrari, Red Bull, and McLaren—will continue to set the pace in 2026.
What Red Bull’s 2026 Engine Development Means for Verstappen and the Grid
Red Bull’s evolving confidence in its 2026 power unit represents a major milestone as the team steps fully into engine development, a role previously dominated by long-established manufacturers. This shift is critical for maintaining their competitive edge in a season framed by new technical regulations.
Max Verstappen’s continued commitment to Red Bull amid intense speculation about his future indicates trust in the team’s direction. However, the observed off-track moments during cold-weather testing underscore the fine margins involved in adapting to a brand-new hybrid power architecture.
As Red Bull addresses these challenges, the team’s progress will be watched closely by fans and rivals alike, with early test performances serving as an important indicator of how swiftly they will leap to race viability. Their ability to refine engine delivery and reliability ahead of Bahrain will be crucial in setting the tone for Verstappen’s campaign and the broader competition within the 2026 F1 grid.
