In the fiercely contested arena of Formula 1, Max Verstappen is currently battling to keep pace with the McLaren drivers in the ongoing world championship race. Despite being the reigning champion, Verstappen is finding it challenging to compete with McLaren, particularly as Red Bull's RB21 struggles in terms of race pace.
Red Bull's chief engineer, Paul Monaghan, highlighted some of the difficulties the team faces, particularly in low and medium-speed cornering. "We're currently more than a second behind McLaren in races like Miami, and we need to improve in those areas to enhance the performance of the RB21," Monaghan stated.
The team’s recent performance dips can be attributed to a series of setbacks over the last year. The loss of pivotal technical figures, including Rob Marshall and Adrian Newey, along with off-track disruptions surrounding team principal Christian Horner, have hindered Red Bull's development between RB20 and RB21.
In an effort to mitigate these issues, Red Bull launched a revised floor at the Miami Grand Prix, but it was exclusively fitted to Verstappen's car. This strategy came with inherent risks, especially during a sprint weekend with limited practice opportunities. Monaghan explained the rationale behind the move: "We can bring it at relatively low risk, and it’s an opportunity to do it. People worked really hard in the factory to implement it and, thankfully, we were able to enjoy the benefits."
The adjustment in the floor was minor, mainly focusing on local airflow management rather than significant design changes. Despite the limited practice, Red Bull found reliable correlation with the new floor setup. Monaghan reassured fans and team stakeholders by stating, "In our judgement of flow stability, the flow stability is unchanged, so we're not fearing it to be aerodynamically unstable. It can go on and we’ll enjoy the benefits."
Looking ahead, this revision is only the beginning of a more extensive upgrade plan set to be incrementally introduced during the upcoming European races. Imola is anticipated to host one of the first major developments for the RB21. When questioned about further upgrades for this upcoming race, Monaghan coyly replied, "I’m not going to confirm or deny any such rumors. You’ll have to wait and see what we turn up with. But if we can make the car quicker, that will come to Imola."
Another crucial area of concern for Red Bull is tyre management. The RB21 has notably struggled with tyre durability, especially in rear-limited circuits and hot weather conditions like those seen in Bahrain, where overheating led to accelerated degradation and impaired performance.
On the other hand, McLaren has consistently demonstrated superior control over tyre temperatures, contributing to their strategic advantage in early-season races. Speculation surrounding McLaren’s use of innovative cooling methods, such as water injection, was quashed after Pirelli’s inspections showed no irregularities, keeping within all regulatory limits.
Red Bull's engineering team is currently exploring how they can replicate McLaren's success in tyre management. Their focus is on developing new aerodynamic solutions, particularly through revised brake ducts and configurations that could help with thermal efficiency. This endeavor has been underway since the season-opening race in Australia.
"Though these components might seem minor, they are crucial to our understanding of how to manage tyre temperatures effectively, particularly by assessing the interaction between the brake drum and the tyre’s inner sidewall," said an insider. This step is crucial as Red Bull seeks to not only catch up but also to reclaim their status at the forefront of the F1 championship.
As the season progresses, the effectiveness of these upgrades and strategies will unfold, providing insight into whether Red Bull can bridge the competitive gap with McLaren and dominate the tracks once again.
