Engine Upgrades Pushed Back and Chassis Complications at Mercedes
Mercedes intended to introduce its upgraded power unit this weekend at the Circuit of the Americas. According to The Race, that timeline has slipped because the new specification is not ready.
The postponement compounds ongoing development hurdles at Mercedes. The team continues working through handling issues on the chassis side stemming from a major aerodynamic package introduced in Malaysia that initially rendered the car slower.
Honda Puzzles Over Turbo Lag and Energy Deployment
Honda spent the break between races analyzing the performance anomalies that frustrated Fernando Alonso during the Singapore Grand Prix. Alonso reported a broken turbo in qualifying, which prompted a precautionary engine change, followed by erratic energy deployment during the race. While inspections at Honda’s Sakura base found no major mechanical faults, engineers identified a gap between expected dyno metrics and real-world turbo spooling. The discrepancy relates directly to how the MGU-K harvests and deploys energy under heavy braking.

Speaking in Austin, Hamilton stated that he made a split-second judgment upon approaching the pit lane entry and realizing Charles Leclerc was also stopping.
