Overview

• McLaren’s investigation determined a failed engine oil line caused an oil leak that triggered onboard sensors to shut the engine down to prevent further damage.
• A strengthened version of the failed part has been installed for the Italian Grand Prix, which Norris says adds only a very small weight penalty.
• Mercedes is assessing the Zandvoort power unit for possible reuse later in the season, with no immediate impact as both McLaren drivers were already set to run fresher engines at Monza.
• Piastri’s win after Norris retired extended the championship margin to 34 points, a significant but not decisive gap with 249 points still available.
• Norris insists he can win the title without relying on bad luck for Piastri, while Piastri says he still considers Norris a serious threat.
