You gain 40 km/h with xmode these car is still green with new parts coming in Australia. They is still a lot we don't know before people jump to conclusions. Merc and redbull spent the whole day in garage.the problem for aston is they missed Barcelona test which they should have used to identify problems and iron out issues. They already warned us they don't expect much in the first half of season but expect improvements in the second half.
Yep, this is what I meant with "it is just Stroll"....no idea how well he can judge a car at this stage. I fear he can not in his overwhelmed situation with barely keeping the car in one piece. I mean...the car is hard to drive, also Alo missed T10 some times. It looked like Stroll never made T10 without locking...
They are using straight line mode so that's not the issue. The reason the car is slow is because the engine is lacking power, or it is having to be run at lower power due to reliability issues. Either way the Honda is looking like a dud.Bill wrote: ↑12 Feb 2026, 18:26You gain 40 km/h with xmode these car is still green with new parts coming in Australia.

Unless the clutch is slipping or the tyre is punctured, irrespective of 'load' (aero or incline or rolling resistance) ; road speed and RPM are linear. Things like tyre expansion, contact patch increase from more aero load etc are too minor, probably < 1% disturbing the linearity.Emag wrote: ↑12 Feb 2026, 16:34Yes, in a single fixed gear with everything else constant, speed scales linearly with RPM, that's basic gearing, and your 30 mph/1,000 RPM example holds. But that's not how it will happen in reality because we don't live in a perfect vacuum with spherical chicken. You get slip losses, tyre expansion, clutch/drivetrain losses and finally, you don't even know if the power unit can deliver the rpms you're extrapolating to.Farnborough wrote: ↑12 Feb 2026, 16:17Funnily enough, that is how gearing works.Emag wrote: ↑12 Feb 2026, 16:01
This is not politics to be honest. They haven't set a single lap where the engine was pushed yet, while other teams are experimenting with deployment maps. And if they actually did push and that's how much it gave, then that's an absolute disaster. These posts that make calculations with rpms are complete nonsense as well. rpm and top speed are not correlated 1:1 and gearing is very important. In any case, just because you gained 10 kmh from 10500 to 11000 that doesn't mean you get another 10 kmh from 11000 to 11500.
If, for example, you chose 7th gear, then each increase of 500 rpm input will give the same gain in road speed, obviating for any tyre circumference expansion at highest rotation and load.
As example, ordinary transmission are often described for top gear as perhaps 30mph per 1000rpm. Meaning, 3000rpm will give 90mph speed.
I concede I was wrong then. I was factoring in other things in my head but I suppose mechanically it doesn’t change anything.

Please continue the PU discussion..... (I just popped in to highlight the above point).
I read a lot about Honda's F1 engine development from 2015-2021 (a thread on this site), and I remember 2017 specifically having massive vibrations which led to horrible reliability. Honda put some experts on the engine in this area and changed the mounting points for the engine. This significantly corrected most of the reliability issues for 2018. Honda is suffering from massive vibrations right now, so hopefully this is something that can be fixed by race 7.gearboxtrouble wrote: ↑12 Feb 2026, 19:18I think the car is just half baked and a few months behind the rest on the development curve. I do not think the potential performance is 4s behind but for various reasons that's all they can manage at the moment. The biggest issues seem to be the engine integration with the rest, the drivability of the engine and gearbox and suspension tuning. These are relatively low hanging fruit and they should make bigger strides than the rest in the coming months. I don't think this is a front running car but they're not the slowest package out there once everything is sorted to get them to the same baseline that the others currently look to be at. They might well be slower than Cadillac at Melbourne but I very much doubt that lasts for long.
