Orihara on Aston Martin's spec 2 power unit changes
Honda trackside general manager and chief engineer Shintaro Orihara said the ‘spec 2’ power unit Aston Martin will run from the Dutch Grand Prix focuses on faster combustion and reduced friction to improve performance. Orihara said: "We focused on improving engine performance, let's say to make combustion faster. It's kind of a secret, but I can disclose a little bit. We changed the pre-chamber to make combustion faster, and also we changed the piston shape to get good combustion. We modified some lubrication systems to reduce friction. We have a quite big list to improve engine performance."

Wolff on Mercedes being out of step on upgrades
Mercedes team principal Toto Wolff says the team are “slightly out of step” with upgrades compared to their rivals but still have a “clear development plan”, as he warned both 2026 championships will be decided by development and race-weekend execution. Wolff said: "We have left points on the table, our rivals have reduced the performance gap, and we know the second half of the year will demand more from us than the first. The championships will be decided by execution and the rate of development we can bring to the car across the next 12 races. Whilst we are slightly out of step with upgrades compared to our rivals, we have more performance to unlock and a clear development plan to do so."

Russell on Mercedes finding cause of straight-line speed problem
George Russell says it has been a “huge load off my mind” after Mercedes discovered his straight-line speed problems at Silverstone and Spa were caused by an issue in the power unit, rather than his driving. Russell said: "It is a huge load off my mind, but also while I'm driving, through Silverstone and the majority of Friday and Saturday at Spa, I think about how I needed to drive to make the power unit fast in the straight. How I pick up the throttle, the gear usage, how early I am on the throttle, and the data was telling us that this was probably the reason [I was struggling], but it turned out it wasn't the reason. So all of that effort over the course of three sessions, trying to re-optimise my driving around a new technique, was kind of for nothing."
