🚨| Adrian Newey on the importance of driver feedback: 🗣"The drivers are wonderfully intuitive animals. They will adapt their driving to suit the strengths and weaknesses of the car. If you want to find out what those weaknesses are, then you have to interrogate the driver."

In early 2022, Mercedes' then-technical director James Allison warned that some teams would struggle and have a "terribly painful" year with the new 2022 ground effect regulations, predicting that some would "get it really badly wrong". https://t.co/XY9eXUMIbz'.

🚨| Mercedes warn several teams ‘have done very little’ on 2026 cars. 👀 According to Andrew Shovlin, several teams will be playing catch-up in 2026. 🤔 I heard that same sentence in 2021 and it ended up being Mercedes themselves struggling till now... https://t.co/KnBiDLOJCj

🚨| Reports that Mercedes and perhaps Audi and Red Bull have designed a way of using a part of the 6-cylinder's energy to the MGU-K to recharge the battery and limit the negative effect of turbo lag. https://t.co/iXbWj56Zdc

Key performance factors for 2026: ✅️ Power Unit ✅️ Fuel ✅️ Aerodynamic & Mechanical Platform ✅️ Weight ✅️ Tyres #F1

🚨| According to L'equipe the FIA ​​and engine manufacturers will meet this Monday to discuss the situation surrounding Mercedes and Red Bull. https://t.co/P8pB6kmNAB

"If you no longer go for a gap that exists in the regulations, you are no longer a racing team." — probably Toto Wolff 🤣 Now seriously, I'd have loved it if it was HONDA exploiting this loophole. But we have to acknowledge Mercedes for their ingenuity. 💯 Still trust HONDA!🤞🏻

⚠️| The 2026 Australian Grand Prix is scheduled for 58 laps. If we take that 0.3s advantage and multiply it across the entire race, the numbers are staggering: 0.3s x 58 laps = 17.4 seconds!😯 Huge advantage for the Mercedes HPP powered teams.🔥 #F1

I have no idea how this loophole even came to public knowledge. I don't think the FIA will be able to do anything about it. Will they force Mercedes to reveal which metal it used and all the expansion parameters? Scary days!

"If you're not bending the rules, you aren't trying hard enough". The technical guidelines state that the measurements are "executed at ambient temperature". Thus, technically it's legal. Not their problem if the wording leaves room for ambiguity. It's just clever engineering

Not sure to what extent this is comparable, but in 2019 Ferrari exploited a loophole with the fuel flow sensor and had to solve it immediately. I understand the Mercedes situation is a lot more complex, however, the FIA needs to be "consistent" and act accordingly.

The Race confirms that Mercedes and probably Red Bull are using phase-changing materials in the cylinder of their ICE in order to increase the compression ratio from 16:1 to 18:1 when the engine is running hot. FIA checks are made at ambient temperature. https://t.co/TasUT3XNxj

⚠️ Mercedes is arguing that since they pass the static test defined in that document, they are legal. 💥 Ferrari, Honda, and Audi are pointing to Article C1.5, which states the car must be legal "at all times during a competition"—including when the engine is hot.

🚨💥Mercedes has reportedly engineered a solution where the engine complies with the 16:1 limit when it is cold (during static FIA testing). 🔥However, they are allegedly using advanced thermal expansion materials that increases Cilinder Volume 18:1 when engine is hot.

🚨WHAT IS THE LOOPHOLE?🚨 By using specific materials that expand at high operating temperatures, the internal volume of the cylinder changes once the car is at racing speed, effectively pushing the ratio back up to 18:1. 🔥This "trick" is estimated to be worth 15HP/3 tenths.

⚠️ Honda, Ferrari and Audi have demanded the FIA for clarification but changes at this stage, just before preseason testing is unlikely. 🤔 Advantage locked-in for Mercedes?

🚨 "Formula 1 engine manufacturers are furious over a loophole in the rules. 👀 Some manufacturers found a way to circumvent the stipulated compression ratio. ⚠️ Mercedes and RBPT have found a way to increase the compression ratio during operation." https://t.co/S5hmILcmVY

🚨| According to Autoracer, Ferrari has marked the front-end as a key area for performance and, as such, has evaluated more than 50 different iterations of front wings in search of the perfect design. https://t.co/Oq1RmXyjEm

🚨| Mekies says it would be "naive" to think RBPT will nail the 2026 PU regulations from the start, and admitted "very tough months". Note: RBPT hired hundreds of people from Honda, Mercedes and Renault. Certainly has the means to catch up in the future. https://t.co/VjvhgtSrl9

🚨| The private Barcelona test will happen from January 26-30 — 5 days of testing. ⚠️ However, teams can only run 3 out these 5 days. ✅️ This accounts as safety net in case teams face reliability, weather or delays problems. https://t.co/oBhG8OT2AB.
