In my experience, you can't always believe what the press writes, team principles rarely speak the facts and when they do, spin them to make the team and/or themselves look better than maybe they actually are.
This is surely true for Red Bull, McLaren, Ferrari, Renault and Honda.

Even if we limit it to F1 that Statement is true for everyone that says something to the Media.

The difference between Renault and Honda performance wise is worth giving up 7 years of Works Support for which is the only 100% cast iron fact out there and tells us absolutely everything we need to know.

I have to believe this. I can't phantom that if McLaren would have believed there was a high probability in Honda catching Renault for the beginning of the 2018 season that they would have gone through all the pain of switching.

By "catching" I mean , HP, reliability, fuel efficiency and amount of electrical power generated by the MGU-H, therefore, how much time the MGU-K can be used over a single lap.


I think In total HP they're close...The reliability it's hard to tell. Honda is doing so much testing on the track that I'm sure that's showing up in their reliability. It's the last 2 items, which might be interpreted as one and the same, where they're is a HUGE gap. The old flashing red light.

An elementary question, but what does the flashing rear red light mean ? MGU-K harvesting, or MGU-H harvesting, or either ? (I guess MGU-K). Can MGU-K harvesting be of varying intensity, I mean it's not just an 'on or off' scenario (I guess, yes, can vary). Lastly, if anyone has a link to a good explanation of both sorts of mechanism, could you post it here, or PM me ? I think I know roughly what they are, but only roughly ! Thanks.

I always thought it meant they had run out of energy to deploy

Floor is one part that can be used for optimum downforce generation through Venturi effect. That is the reason why a lot of purists, want higher levels of ground effect and want a lot of these wings be simplified, for better racing. Lowering the wake with reduced wing elements, helps car follow closer.
Is there any evidence that supports the view that lower wake helps car follow closer of that less wing downforce helps cars follow closer?

Im going to suggest that at Mexico it was much harder for cars to follow closely. Further due to the lower air density even having one of the longest straights in F1 and DRS it was very difficult for one car to get past another slower car.

I think that running very high drag would actually make overtaking easier as the slipstream would be a much higher benefit.

This will help you gain some more understanding of the "Wake" issue.

Highlighted the key word.

FWIW I am in agreement with Bhall from your link (as I was the last time this was discussed)

Quoting from Bhall:

Image

There was a big change in Aero rules between 2008 and 2009 which greatly simplified the cars, removed a lot of the sensitive winglets and there was absolutely no change in the amount of overtaking in the season.

From this:

to this:

Made absolutely no difference at all.

But sorry I am dragging this somewhat off topic.

You could at least have used pics of Mclaren cars!! Lol

Turned down the chance to meet Vettel at Silverstone in 2007. He was a test driver at the time and I didn't think it was worth queuing!! 🤦🏻‍♂️

Did you try and understand what could have been the reason, why the overtaking trend was such, through the years? Let me try and help.

The numbers of cars participated over the years.
Image

This is the % AND NOT the actual number of overtakes. I will explain why this is accurate.
Image

And if you see there, THERE WAS AN INCREASE in overtakes in 2009. Something more interesting here. I have taken qualifying performance from Malaysian GP in 2008 and in 2009 as a reference. As the track generally offered good overtaking opportunities, this is a good reference.

2008
Image

2009
Image

Observe the performance difference between the top 10 cars from 2008 to 2009. The field got bunched up! Which means, lower overtaking possibilities. But again, here is another interesting statistic. The DNFs in 2008 and in 2009.

More DNFs in 2008, compared to 2009. Had the 2008 cars managed to have the 2009 reliability, there was theoretically more overtakes possible. Contrary to that, if the field in 2009 was as spread as it was in 2008, theoretically, more overtakes were possible. Different factors balancing the act, but in different ways! But, if you look at the first picture, it shows that the % of overtakes increased 2009!

2008
Image

2009
Image

And compare the reliability situation to 1991. (Click to enlarge). 34 cars and disastrous reliability. If those cars would have had the 2011 type of reliability, the overtaking numbers would have gone out of the roof.
Image

This is the qualifying performance difference between top 10 cars in 1991 USA GP. With such a large performance gap, there must have been great number of overtakes, but the balancing factor was bad reliability that never allowed cars to really be on track in races. If the cars of 1991 would have managed a reliability like that of 2016-17 Mercedes cars, Ayrton could have lapped the last 15 (of the 34) cars, atleast 15 times in the race. That is around 225 overtakes in one for race for one driver alone! Ayrton had lapped the 8th placed Gabriele Tarquini, 4 times.
Image

So, the truth of the matter lies in the details of the situations. Factors like number of cars participated, performance difference between the cars and the reliability issues have all contributed to a skewed picture of overtaking over the years. The overtaking graph considers none of those factors as I don't think the intent was that either. It just shows number of overtakes, without going into any further details.

Simply looking at a trend graph says nothing. When a credible driver talks about his difficulties in overtaking, it has to be granted a level of authenticity.

Mods, please move this discussion to an appropriate thread. Thanks.

It seems the ban on refueling did more for overtaking than the new aero regs of 2009 did.

Lets ban refuelling. Oh wait...

the key for more overtakes is the tires...sort life tires and more pit stops...3 types with 15-18 laps life with 2 of them must use ...for 3 and more pit stops per race ...and giving all drive style

In 2010 we still had Bridgestones which could probably last the entire season

Actually it started from a floor related aero discussion about wake and that lead to its effects on overtaking etc. Completely off topic but hope the mods will move it because it is quite interesting

Alonso probably testing with Toyota LMP1 before the end of the year... Isn't Alonso a Honda driver until the season ends? I would like to hear Wazari's opinion on this, in Japan it must be important I think.

Again it would be more suited to the McL-32 car thread...
