Max Verstappen has raised concerns about the readiness of Red Bull Racing’s Ford-powered powertrain ahead of the 2026 Formula 1 season, emphasizing that significant development remains. During a private five-day test in Barcelona aimed at preparing teams for the upcoming regulatory overhaul, Verstappen openly stated that there is still
“quite a bit of work to do”
on the new package.
This season marks a significant turning point for Red Bull as they return to supplying their own power units for the first time in over two decades, backed by Ford’s engineering. Despite Verstappen’s status as a four-time world champion, the team is not yet in a commanding position due to setbacks experienced during initial testing, including limited track time and reliability issues.
Testing Difficulties Affect Red Bull’s Preparation
The opening days in Barcelona proved challenging for Red Bull, as Verstappen’s rookie teammate Isack Hadjar took charge on Monday, restricting Verstappen’s running early on. Weather interruptions further shortened practice for the team. Following a notable crash by Hadjar, Red Bull was unable to return to the track until the final day of testing, where Verstappen logged an impressive 118 laps but acknowledged the ongoing challenges.
Reflecting on the car’s development, Verstappen remarked,
“Still work in progress, but I think we’ve hit the ground running quite well with those things.”
He also highlighted the complexity of the new regulations, stating,

“It’s still a very complicated formula for everyone, there’s still quite a bit of work to do, but that’s normal.”
Mercedes Sets High Standards in Initial Trials
In contrast, Mercedes showcased strong progress during the testing sessions, completing the highest number of laps among all teams. Their young talent, Andrea Kimi Antonelli, successfully carried out a full race simulation, signaling promising reliability and performance.
George Russell, Mercedes’ lead driver, expressed optimism:
“I think it was a very positive test. The car’s feeling nice to drive, no major issues, no porpoising, which is pretty good news for all of us.”
After struggling since the introduction of ground-effect cars in 2022, Mercedes appears poised to reclaim competitiveness.
Despite this confidence, Russell cautioned against premature judgments, noting,
“On the power unit side, there’s some impressive things from some of our competitors and that’s quite surprising, to be honest,”
and added,
“You don’t want to judge too much into that. Time will tell.”
Looking Ahead to a Pivotal Season in Formula 1
As the 2026 season approaches, the competition for supremacy intensifies, with Red Bull determined to refine their new powertrain and challenge the established frontrunners like Mercedes and Ferrari. Verstappen’s warning underscores that while progress has been made, the journey is far from complete.
The unfolding power unit developments will be crucial in shaping the championship battle, setting the stage for what promises to be a fiercely contested season in Formula 1.
