Honda flags La Monumental as 'challenging' for 2026 engines; Aston Martin dismisses 'killer track' label

Honda has warned that the banked La Monumental corner at the new Madring circuit will be "quite challenging" for the lubrication systems of F1's 2026 engines, while Aston Martin has pushed back on James Vowles' "killer track" description.

Why it matters:

The Madring hosts its first Spanish Grand Prix this weekend, and the unique 550-meter banked right-hander at Turn 12 — the circuit's signature corner — is expected to put unprecedented stress on the new-generation power units. With entry speeds predicted at 300 km/h and sustained 4G compression, teams are bracing for potential reliability issues that could shape the race.

The details:

• Honda's trackside general manager Shintaro Orihara said the corner's combined lateral and vertical G-forces will be a major test for the lubrication system. He confirmed Honda will start with a conservative setting and increase the margin step by step for qualifying.
• Aston Martin's chief trackside engineer Mike Krack disagreed with Williams boss James Vowles' "killer track" assessment, noting that changes have been made since the F3 test, including resurfacing and tweaks.
• The recent F3 test at the street circuit saw 19 red flags, 11 of which were caused by barrier contact, highlighting the track's unforgiving nature.
• Krack said teams are studying the F3 test data for early clues, but added that no additional data was supplied to teams ahead of the inaugural race.

What's next:

The Spanish GP weekend will provide the first real answers on how the 2026 cars cope with La Monumental. Teams will adapt their setups and engine mappings as data comes in, with qualifying likely to reveal the true pecking order.
