As the 2025 Formula 1 season rolls into Spielberg for the Austrian Grand Prix, the racing world faces something unusual: Max Verstappen will go into the weekend without his trusted race engineer Gianpiero “GP” Lambiase by his side. For the first time since joining Red Bull in 2016, Verstappen and GP will be separated—owing to Lambiase being away for private reasons. But make no mistake, this is no default scenario. Let’s unpack why this matters, the legacy of their partnership, and what it means heading into Austria.
Why Is Lambiase Away This Weekend?
On June 27, 2025, Red Bull confirmed that Gianpiero Lambiase would miss the Austrian Grand Prix “due to personal circumstances”. No further details were shared, only that he would return for the British GP at Silverstone. In his absence, veteran race engineer Simon Rennie fills the role—a logical substitute given his extensive F1 résumé.
The Verstappen–Lambiase Legacy
Since Verstappen’s switch from Toro Rosso to Red Bull in 2016, Lambiase has not just been his engineer—he’s been the anchor and steady voice guiding four world championship-winning seasons (2021–2024) and numerous on-track triumphs. Known for delivering precise, unfiltered feedback over the team radio, Lambiase has developed a reputation for keeping Verstappen focused—even saving him from his own blistering temperament. The two have built a synergy anchored in trust, earning them the moniker of F1’s most formidable driver-engineer pairing .
The Reinvention: Simon Rennie Steps Up
With GP away, Simon Rennie—Red Bull’s Group Leader of Simulation Engineering—will handle Verstappen’s race engineering duties. Rennie is no unknown quantity: he began in F1 with Renault in 2004, engineered Fernando Alonso, Kimi Räikkönen, and later Mark Webber and Daniel Ricciardo at Red Bull between 2013–2018. He even stepped trackside for Alex Albon in 2020 following a stint in the factory.
That experience makes him a familiar voice to Verstappen, who has engaged with Rennie’s insights during simulator sessions. But stepping into GP’s shoes mid-season—and at his home race no less—won’t be without challenge.
What’s at Stake This Weekend?
Lambiase’s absence arrives at a critical moment: Red Bull is rolling out upgrades at Austria and Silverstone in a last-ditch effort to close ground on McLaren ahead of the shift to 2026 regulations. Verstappen heads to Spielberg seeking a record fifth Austrian GP victory, yet he isn’t guaranteed a walkover.
Without his familiar radio partner, a few key questions arise:
Driver-System Chemistry: Can a sportwhere intuition and instantaneous communication is key, Rennie step seamlessly into GP’s slot?
Pressure Response: Verstappen has been known to grill his engineer over slow strategy calls. Will the synergy hold if Rennie pushes back?
Performance on Home Soil: With upgrades inbound and home expectations high, how will the newcomer-in-the-pit-wall impact Verstappen’s performance?
Verstappen’s Comments & Outlook
While Verstappen hasn’t specifically addressed GP’s absence, he remains vocal on broader team dynamics and performance:
-
He dismissed media questions about altering his driving style ahead of a potential race ban, snapping:
“You’re joking? Is this like a trap?”—underlining his unwavering on-track focus.
-
Reflecting on the upgrades and weekend, he said he remains hopeful the new parts give Red Bull a chance to “close the gap a little bit” on McLaren.
Though verbal support for Simon Rennie was implicit, Verstappen’s comments suggest an unbroken, win-first mentality even amid change.
Historic Perspective
It’s rare in F1 to see a driver separated from a long-time engineer mid-season—especially at a track where their partnership has delivered repeat victories. A split like this highlights just how rooted the Verstappen–Lambiase bond has been in Red Bull folklore.
Think back to 2021–22: Lambiase managed Verstappen’s quest for podiums with unflappable calm, navigating him through penalties, strategic gambles, and high-pressure laps. Now, at Spielberg—with its high-speed straights and fervent home support—he’s not trackside. For both Verstappen and the team, this absence will be a crucible test.
Final Word
Max Verstappen racing without Gianpiero Lambiase at the Austrian GP is a rare twist in a well-established story. With Simon Rennie stepping into the pit box, the weekend promises intrigue—not least in the radio exchanges, strategy calls, and tight on-track battles.
Whether this proves as a one-off disruption or a demonstration of Red Bull’s strength in depth, the result will echo loudly beyond Austrian asphalt. For now, all eyes and ears are tuned to Spielberg, where a champion races on instinct, talent—and a new voice in his ear.
