Christian Horner confronted questions concerning the rumours that Crimson Bull and Mercedes have discovered an engine trick forward of the 2026 Formulation 1 season.

Heading into a brand new set of rules, stories emerged that each the Milton Keynes outfit and Mercedes had discovered a loophole within the rules to extend the compression ratios.
For 2026, the engine’s compression ratio is proscribed to 16:1. Typically, the next compression ratio presents elevated thermal effectivity. Mercedes and Crimson Bull are thought to have made use of the truth that it can solely be measured when the automotive is static at ambient temperature, permitting the compression ratio to rise to 18:1 when the engine is in movement and as much as working temperatures, though it’s value noting that this has not been confirmed.
“Formulation 1 is about pushing the boundaries. It is about the way you interpret rules. All the time has been, at all times shall be,” Horner mentioned as he danced across the query.
“Groups which might be essentially the most conservative are the groups which might be by no means on the entrance of the grid. You have to be pushing the envelope. And naturally, it is all about the way you interpret rules, and engineers, a few of the brightest engineers on the planet, shall be these rules and pondering, ‘OK, how can I maximise efficiency?'”
Mercedes group chief Toto Wolff responded to complaints from different energy unit producers on the official launch of the W17. “I simply do not perceive that some groups focus extra on the others and maintain arguing a case that could be very clear and clear,” he mentioned.
“Communication with the FIA was very optimistic all alongside and it is not solely on compression ratio, however on different issues too. Particularly in that space, it’s extremely clear what the rules say. It’s totally clear what the usual procedures are on any motors, even exterior of Formulation 1. So simply get your shit collectively.”
He added: “The facility unit is authorized. The facility unit corresponds to how the rules are written. The facility unit corresponds to how the checks are being performed.”
