That initial leap toward life away from long-serving race engineer Gianpiero Lambiase was far from straightforward, as The Race reports. Max Verstappen faced a messy United States Grand Prix featuring a middling start, strategy annoyance, and radio communication problems that were flat-out labelled a "disaster." Thankfully, none of those headaches had anything to do with future engineer Tom Hart being by his side for the very first time.
Red Bull is busy phasing Lambiase out ahead of his switch to McLaren by 2028 at the latest, meaning the team has started handing Hart significantly more responsibilities. After filling in during a few practice sessions since the summer break, Hart stepped up for the entire weekend at Austin while Lambiase kept a watching brief in the background. It was a proper baptism of fire, especially given those baffling radio issues, but the team remained remarkably upbeat about how the pairing handled it.
Team principal Laurent Mekies praised the effort, noting that Hart picked a fairly complicated race for his debut. "I think he did an excellent job, and you see me smiling because I certainly remember what it is to be on your first race as a race engineer," Mekies said. He added that Hart managed to channel the work of the engineering teams behind him to Verstappen very well during the first qualifying and race.
Building a telepathic driver-engineer dynamic cannot happen overnight, and Red Bull knows it will take time for Hart and Verstappen to reach the level of understanding that Verstappen has enjoyed with Lambiase. Still, Mekies felt the dynamic bedded down as well as could be expected under the circumstances. The team walked away frustrated with a P3 finish—which Mekies considers good news—and full confidence that Hart will continue ramping up his partnership with the driver.
The evolution of this garage dynamic will continue throughout the remainder of the season, with Hart and Lambiase set to alternate the role over the remaining races. Longer term, Hart is scheduled to take over fully from the beginning of 2027, though the exact nature of Lambiase's mentoring role depends on how long he remains involved at Red Bull. No departure date has been agreed for Lambiase to join McLaren as its new chief racing officer, and his contract runs out at the end of next year.
Red Bull is not eager to let him go early, whereas McLaren wants to secure him as soon as possible, ideally at some point in 2027. The tension became public at the Spanish GP in Madrid last month when McLaren CEO Zak Brown held a brazen public meeting with Lambiase in the paddock to draw attention to the ongoing discussions. Meanwhile, Red Bull's priority is keeping Lambiase around to ensure a smooth transition to a new structure, which also includes the arrival of Aston Martin's Tom McCullough as its new head of racing. Since McCullough does not begin work at Milton Keynes until January, Lambiase must remain on board into the early part of next year to assist with the handover.
