Last year when the Mclarens stopped because of powerunit failer they would blame it on the chassis I assume mercedes has something in there contract that forbid their customers from blame them for any failures it's about protecting the brand. I will assume that honda has a similar arrangement with aston.aran.vtec wrote: ↑20 Feb 2026, 08:50This really looked like a drivetrain issue, car was stuck in gear and for some reason the rpm went to 13,000rpm twice but didnt move forward(almost as if it was out of frustration but there was no throttle input which was odd), if anything you try and protect the ICE by restricting the rpm as low as possible.

It includes:
Unfortunately, his afternoon session ended early after Honda identified a power unit-related issue and, as a precaution, the team stopped the car. It was returned safely to the garage for further checks and maintenance.
So the official team info identifies a PU issue. Obviously the onboard video shows the PU was at least running at time of shut down. Well, unless it expired after drive was lost and the increase of revs (perhaps some fault that meant loss of control, but not absolute stop of the engine, if we assume the issue was precipitated by the PU?).![]()
