On the topic of Mclaren having short'er' gear ratios in their gearbox and our guessing game as to the reasons for it (the reasoning being very different, quite opposite in fact, between so many members and myself, at the risk of my reasoning boomeranging and biting me in the posterior later :D ) ; I am observing something in mainstream media headlines - about how Stella/Piastri have made it a point to tell the media how the start can be 'dangerous', 'safety concern' - I have my doubts whether they are simply playing the Toto Wolff game of trying to cover up their inherent flaw with some FIA issued TD of some kind. McLaren's "shortest of all" ratio may render them spinning the wheel (whether the track traditionally requires a 1st or 2nd gear start) and go into anti-stall, in a way that they can be 'caught' between a rock and a hard place - 1st gear being too short and 2nd being too tall, while others can comfortably start in 1st. Just a hunch.
In all the videos I saw of standing start practice, Lando and Oscar didn't have any major issues, like stalling, loss of acceleration, and so on. But that could happen in a real race. The problem Stella raised is very real, and I support him. It's the FIA ​​that's messing things up. The same goes for the Mercedes engine. The FIA ​​didn't see the problem, and now Mercedes could be outlawed. If I were the FIA, I'd say that in 2027 we'll change the regulations to include a procedural review, like, "You have to change something in your engines." The matter is closed. Any protests will be illegal. You can't blame those who built the engine entirely according to the letter of the law.

Getting back to the start. This never happened before; everyone took off with full energy. But now, you see, it's only when they reach 50 km/h. You have to admit, that's idiotic. :) And this is an organization that supposedly works for safety around the world. I hope that the starting procedure will be revised, otherwise the races will turn into a farce before they even begin.

In any case, I think this round of gear talks came about because venky suggested that wheelspin might cause anti stall at the start, my point being that they won't deploy at the start and the power is halved. But beyond that, I don't get why wheelspin would cause anti stall, I would have thought that would only happen when gears get too low, not when the revs are higher than traction would allow.
When too much torque goes through (shorter starting gear), it will spin, the driver would have already upshifted (reflex) and will simultaneously lift & brake (again reflex) for a moment as soon as he realizes the spin, the torque would disappear; and then once he gets on the gas again, the 'load' would already be too much for the higher gear => anti stall. Except for the spin, this lift+brake and then reapply gas pedal is how they get trapped in anti-stall when they make a momentary false start, realize it, and try to stop the car creeping.

I think the philosophy of the Mclaren is more on the side of using super clipping at end of straights for regeneration (higher RPM with short gears) since they think driving at higher top speeds is not as efficient. They get to their top speed quicker with the shorter gears, but then stop accelerating because the gears are shorter. The downside would be the lack of straight-line speed race-ability compared to others.

Other teams seem more focused on maximizing the harvesting in the brake zones with aggressive downshifting. The downside to this approach is excessive rear tire wear. Considering Mclaren's philosophy with the tire management, then it makes sense that they prefer to have a more stable balance of the tire wear over the stint. With how much torque the MGU-K has, it's actually very important to have good traction. If you are taking too much out of the rear tires in the brake zones for recovery, then you won't have the grip later in the stint to use that power. It's a vicious cycle. It could pay off for Mclaren to be more selective about how the rear tires are stressed.

No MGU-K until 50kph.
They'll be hitting that before phase 2 of the launch, so the MGU-K should still play a massive role in race starts.
If they choose to use it, do you think they will deploy battery power at 50kph..?

I would have thought that race starts will be traction limited well past 100kph. Will we deploy ERS in 2nd gear??
Possibly. I think they'll have the ability to blend power in with speed using curves, but it will depend on available traction as you said. May depend on compound and track conditions.

100% agree on rears, its what I've been saying, they will be key this year to a strong weekend. Can imagine more rear instability in corners and brake balance issues causing deg and mistakes in racing conditions. Certainly earlier on.

Longer gears would provide more progressive braking though, or am I mistaken. Thinking of corners where multiple downshiftscare required, engine braking is not smooth as you change down again and engine braking increases once more. Sounds like it would change balance mid corner.

If we are just talking false start then that is an exceptional circumstance and they might well be harder to deal with, but can't see brakes being applied anywhere else during start sequence to cause anti stall

I imagine another issue with using engine breaking is it is less precise than using the brakes and brake balance, so I imagine it will take some effort to keep the rear in check, maximise energy recovery and get through the corner quickly.
A good F1 team is going to integrate the downshifts into the brake-by-wire logic. So the brake-by-wire controller predicts the downshift torque reversal based on the current wheel speed, current engine speed, current gear, next gear, and could blend out the mechanical brakes automatically while the downshift occurs to avoid sudden rear wheel locking.
Missed this, thanks.

I thought this would be something basic, happening right from 2014 itself.

I have a feeling McLaren will show stronger performance this week, particularly on their race sims. There seems to be quite a bit to extract from the PU side, thy must have done some learning.

Well, I had some free time and watched the entire 2016 Bahrain Grand Prix race. The conclusions I made from my observations were quite interesting. I raised the issue of race pace earlier. Qualifying pace doesn't interest me because points aren't awarded in qualifying. Moreover, energy management is paramount in the race, and it's more difficult than in qualifying.

So, the average race pace, based on race simulations last week, shows that the leaders' average times are between 1 minute 38 and 1 minute 39 seconds. Of course, this is just the first attempt. The cars will be further refined, with tires and chassis settings adjusted, and the electrical system optimized. Some teams have already chosen softer C4 tires for testing tomorrow. We'll see how this will positively impact average race pace, and whether these tires will be used more heavily in the race or just for one qualifying lap.

Let's just take as an example that cars are capable of running consistently for 1 minute and 38 seconds as an average time throughout the entire race by taking the total race time and dividing that time by 57 laps. The most important thing is that this is a confirmed time based on a real race simulation and not just a time taken at random from nowhere. Now let's compare the times set by drivers from mid-level teams, where 1 minute 37 seconds and 1 minute 38 seconds are quite representative. This is from Bahrain in 2016. The tires used during the race were Super Soft, Soft, and Medium. The majority of the race involved three pit stops. On fresh tires, the times dropped to 1 minute and 35 seconds, then rapid tire degradation over the next 15 laps made itself felt and the time dropped to 1.37.5, while for others it dropped to 1 minute 39 seconds. It's harder to get an average time from the leading Mercedes and Ferrari teams, as they were given little time and the infographics for them were scant. But their pace was faster, meaning their times were better.

For example, Romain Grosjean's time on lap 14, when he was already driving on fresh Super Soft tires, was 1:37.285, and 10 laps later, by lap 24, it was 1:39.265. A loss of 2 seconds. Modern cars with harder tires don't have such rapid tire degradation. On lap 33 of the race, he had a time of 1:37.600 on a different set of tires. Kevin Magnussen's best time on lap 33 was 1:37.106, and his latest current time was 1:38.861. Rosberg, the race leader, had a latest time on lap 36 of 1:36.232, Raikkonen's 1:36.467, and Hamilton's 1:36.784. All three leaders were driving on the re-rolled Supersofts and had all made two pit stops by that point. On lap 39, Ricciardo, who was running on soft tires, had a lap time of 1:38.339, while his best was 1:36.510. Rosberg's best time of the race was 1:34.482. After the final three pit stops, by lap 43, Rosberg and Raikkonen's times had dropped to 1:35.5. By laps 48-50, they were down to 1:36.2. By lap 55, they were down to 1:36.9. Without the safety car, the race time for the leader was 1 hour 33 minutes and 34 seconds.

So far, the following conclusions can be drawn: at racing pace, 2016 cars are even faster than 2026 cars.
This is exactly what I wanted to draw my attention to. The 2016 cars confidently reached 330-336 km/h on the starting straight. Current cars can do the same, but in a race, this can result in a loss of up to half their power. Overall, it will be fun.


Oh, and if anyone thinks this is a joke, here's a little bonus: Hamilton's 2016 Bahrain pole time was 1:29.493. :D

I agree with that, as per the downsides, there are some initial indications about Mclaren's lack of race-ability due to the shorter gears and considerably lower top speeds.
"In the past, DRS created such an advantage from an aerodynamic drag point of view for the following car," Stella set out. "This year, when you follow somebody, you have the same drag and the same power, so it becomes quite difficult to overtake. Our drivers have been racing with other drivers during these three days of testing in Bahrain and they found it extremely difficult to overtake."
https://www.motorsport.com/f1/news/mcla ... /10797523/

I think there are fundamental problems baked in to the regs that make it hard to overtake (lack of energy for overtake mode, etc), but Mclaren hasn't done themselves any favors with having a lower top end than others either.

LoL, That's not what I meant.
Meant to say that you are right, and right about it from 2014 itself. I am sure they faced the rear locking related to downshifts and would have used the 'facility' of the MGU-K as a sponge to absorb the spikes. This time they need to 'just do more' (as Will Joseph so eloquently put it, in Vegas).

A lot of discussion about gear ratios and how for some this means that McLaren has a drag problem because of choosing relative lower ratios compared to the competition and how this handicaps them in terms of top speed… Can anyone share the data showing that McLaren’s top speed is gear ratio limited? What are the assumptions to based that on?
