Last year the most points a team took from the midfield was by Haas 22 points in Austria (if memory serves.) 10 points is generally considered an excellent weekend in the midfield, but there are days when those out front fall apart and a team can make massive gains. Reliability is a key factor in being there for those days where the top three mess up.

 

Well realistically, the only cars falling apart out of the top 6 last season where Renault power units whether it was manufacturer or operator error. And they don't have those in the top 6 anymore. Bettering 7th on track will more rare this season than last.

If you start posting in other team or driver threads then perhaps you would have less judgement from those here.

"Posting in other team or other driver threads"
Is there a rule i missed? I mean its Renault and i'm not French. Do i have to ask the moderators if its allowed to post anyway?

I am not a fan of Renault. The way they handle things. Excuses, not fullfilling promisses and always pointing at others..yuck.
But a huge fan of Nico. If he had not signed for Renault he would be driving a Mercedes now. Its a harsh world.

I am sure Merc had the chance to sign him instead of Bottas (which I would have done), so I don't think he would have been anywhere close to a Mercedes or a Ferrari now. 

 

I thin Nico's best chance is Renault, Daniel on the other hand could have stayed at RBR and be competitive till another seat opens up, or maybe Renault build a beat next year or 2021 and both know something the outsiders don't

1)Sainz used H and S. Not H-M. So there goes your argument.

2)Hulk had a MUCH better tire choice in Bahrain. New tires all through the race vs Norris who started on old softs and ended the race on old softs and yet Hulk was just 2.5s ahead of him when he retired. See how I just used your argument against you? Renault was not a better race car on sunday in Bahrain using your argument.

3)Sainz had damaged to his entire boomerang that would disrupted flow to the back of the car AND the leading edge of the floor in the bargeboard area. There is no way a damage that big would have not caused major diffusor performance drop because sealing of the diffusor and rear wing efficiency as well diffusor efficiency would drop. Loss of a major bargeboard component would have affected R-L aero balance.. If anything, he probably lost over a tenth because of that.

So as of now, the facts say that Sainz used Hards and softs, Sainz had significant damage and Sainz was faster than Ricciardo by 9 seconds while being in no man's land for 95% of the race vs Ricciardo who was being pushed by Perez for 100% of the race.

This is not my opinion. I have not passed a judgment on what car was faster. I presented facts and water is wet, you can't argue against that.


Omg... I stopped reading your "facts" when you wrote the H-S is the very same strategy as the S-H. :D

Where exactly did I say that?

Is this one of those “I don’t like what I hear/read so I am just gonna make arguments over things that did not happen” or “I don’t like what I hear/read so I guess it’s fake news”.

If you actually bothered reading my other post, you would have known that I mentioned how they ran a very different race and you can’t really draw conclusions.

It’s funny how you make a statement about Sainz using mediums that can be refuted by a quick google search and then try to accuse someone of saying something that was never said in the first place.


Sigh.

Unless all the engines are placed on the bench and are measured by let's say the FIA, all these 'facts' are useless.

 

Speed traps are useless because of config. Williams used to top the sheets and were being lapped while Verstappen was winning races being at the bottom. Not too mention the influence of tows/drs overtakes etc.

 

Driver reactions are useless because none of the Renault drivers are going to say anything bad about their employer, of course they say it's a powerful and great engine. Well except Verstappen for the last 2 years.

 

Year-on-year comparisons are also useless because of new rules and regulations (incl. tyres), external factors such as weather. You could for example say:

 

2019 China quali

Fastest Renault: 1:32.958

Fastest Toro Rosso: 1:33.236

 

2018 China quali

Fastest Renault: 1:32.532

Fastest Toro Rosso: 1:33.795

 

I could say that the Renault engine is worse than last year, while the Honda is step forward.

 

Would I say that? No. Because it's a combination of driver/car/engine. There's no way for us to to make any sense of these performances.

 

The only thing, that everyone can see, is that the reliability of the Renault engine package is abysmal.

 

 

Dont know where to start...

 

1-Qualy speed traps are very useful. I'm a talking about qualy not race or fp... In qualy there is no tow (or rarely - and Renault didnt use that) nor overtake -_-' while drs, engine mode, fuel, tires and conditions are the same for everybody...

2-I'm comparing multiple qualy speeds traps, every 2018 and 2019 qualy. And there is a tendency, a constant change in them. there is a big change and improvement in every speed trap sheet...

3-the drivers can be very objective too, especially Hulkenberg and especially when he talks to other medias, like the german ones. He dont hesitate to pin point the weaknesses of his cars.

4-when this objective driver and other Renault drivers used to downplay/minimise the power gains in the past, they do the opposite this year and talk about big engine gains and no chassis gains.

5-that same driver said in 2018 that Renault's lacking was around 60%chassis and 40% engine or the way around. This year this driver who "isnt going to say anything bad about their employer" is blaming only the chassis. He also pinpointed the engine and chassis lack of development last year.

6-What about Sainz? is he a Renault driver? and he's is also a quite frank driver and talks about huge gains.

7-the rule changes are the same for everybody

8-and we're not talkin about a Williams or a HRT, we're talking about a car with very decent DF level and performances, so a decent drag level.

and there is still al ot of arguments against your load of nonsense

YOU cant make any sense of the performances because of your very simplistic "reasoning" and anti-Renault posture...

The engine made a big step performance wise and the chassis performance (compared to the top 3) is the problem, those are facts, which are also backed by the gps datas that AMuS and others gathered in every gp... 

Hosnestly only a fool or a troll thinks like you. And judging your record, avatar etc, it's mainly trolling and dishonesty. 

Regarding unreliability, it's not necessarily the "package" like you say. the only problematic part for now is the MGUK.

But one should indeed wait to see several tracks before judging the pace, as already stated, especially in the situation of Renault this season.

:lol: 
"acknowleging the complexity of the matter" do not mean brushing every fact aside, mixing everything together and even pretending that people are lying...
let alone understanding the matter...

 
Now, after seeing the list of the people who liked or approved statsman post (which include arrowslivery and artgp - which harms the credibility of statsman message even more) I'm even more confident that I'm on the right path  :)

I'm going to ignore all the insults (that Renault criticism hits you hard!) and just respond to the other stuff:

 



Dont know where to start...

 

1-Qualy speed traps are very useful. I'm a talking about qualy not race or fp... In qualy there is no tow (or rarely - and Renault didnt use that) nor overtake -_-' while drs, engine mode, fuel, tires and conditions are the same for everybody...

 

In qualy there is no tow (or rarely - and Renault didnt use that). No tow, or rarely. Eh yeah.. Red Bull used a tow when they had a Renault engine. And it all became a problem when one driver didn't tow the other on an occasion. McLaren used a tow all the time, the ALO/Stof tow even became a thing. And the ones who were towing were all Renault engines. So yeah, there's no tow in quali, except when there is..

 

2-I'm comparing multiple qualy speeds traps, every 2018 and 2019 qualy. And there is a tendency, a constant change in them. there is a big change and improvement in every speed trap sheet...

 

Again, speed traps don't say jack sh**. Again, car config and external factors play a big role. Verstappen won with low speed traps, Williams was lapped when leading the speed traps. The only relevant splits are the sector times

 

3-the drivers can be very objective too, especially Hulkenberg and especially when he talks to other medias, like the german ones. He dont hesitate to pin point the weaknesses of his cars.

4-when this objective driver and other Renault drivers used to downplay/minimise the power gains in the past, they do the opposite this year and talk about big engine gains and no chassis gains.

5-that same driver said in 2018 that Renault's lacking was around 60%chassis and 40% engine or the way around. This year this driver who "isnt going to say anything bad about their employer" is blaming only the chassis. He also pinpointed the engine and chassis lack of development last year.

6-What about Sainz? is he a Renault driver? and he's is also a quite frank driver and talks about huge gains.

 

4 replies stating that drivers are capable of speaking corporate language. They're very honest! You know when they don't care about being nice, when someone like Prost got fired for bashing his Ferrari car, when Alonso spoke of a GP2 engine, or when Verstappen trashed the Renault engine for its reliability.

 

7-the rule changes are the same for everybody

 

Since you've included 2018-2019 comparisons, in other words year over year, the rules and regulations have changed and thus comparisons are worthless. For everybody.

 

8-and we're not talkin about a Williams or a HRT, we're talking about a car with very decent DF level and performances, so a decent drag level.

and there is still al ot of arguments against your load of nonsense

 

It's not you who get to decide which car or teams have "decent performances". You seems to think Renault is decent, I happen to think not. I might think the Toro Rosso has a decent performance, you might not. See how that works?

 

 

Regarding unreliability, it's not necessarily the "package" like you say. the only problematic part for now is the MGUK.

 

Which is part of the package, to have a fully functioning PU....

Btw, you think it's only the MGU-K, it might be more it might not. Who knows? Did Cyril take you backstage and show it to you? You're always stating opinions as facts.

Qualifying telemetry comparing Ricciardo to the two Red Bulls

 

PU seems better than Honda. Ricciardo is slightly faster on the straights once out of the traction zones but is running more wing (gap widens quite dramatically when DRS is deployed).

 

Just need to sort the reliability out.

Interesting graph.

I don’t see him being faster in traction zones. The DRS gap is remarkable, but does it necessaraly imply more wing?

Reliability is not Renault’s only issue if, as you suggest, its power unit has more grunt than Honda’s, its rear wing produces more downforce because DRS affects it more than the Red Bull and yet Ricciardo loses almost a second a lap to Verstappen. Also when you say “just”, do you realise these relaibility issues have been going on for years now?

Ric's speed curve is above Vertappen's but he loses time ?!

Gearing is pretty different - RB hits 8th way way earlier - so probably they set it too short?! Can they change it mid season? Renault gears look too long...

In Ferrari vs Mercedes thread on f1technical, tehre were claims that if Ferrari wins big time AFter DRs activation this means they run lower downforce wings...

Couple of things I (think) can see. Tell me if I'm wrong

 

- Max much later braking into T1 and carries more speed through 2-3

- Dan carries more speed into T7 but spends more time feathering the throttle whereas Max and Gasly both have a more ubrupt burst then lift through T7-9. Hard to read, but perhaps the better downforce and stability on the Red Bull shows here. 

- Max and also Gasly get on the power much better through T13, whereas again Dan has to fight through the corner making small adjustments on the throttle

- Throughout most the lap Dan shifts down one more gear. Does this indicate slower cornering speed?

- Dan lost most of his time in T2-3 and exiting T12 into the long T13

I said once out of the traction zones, not in them. RB's chassis advantage shows there.

The article it was ripped from claims this is the reason. But i'm not sure myself.

Have read a quote that Honda will have +20hp in Baku Qualy mode.  And that this therefore puts them within 18hp of Merc and Ferrari.

 

So where do we reckon the Renault sits in all this?  They could be still anywhere from 20-40hp down in the Q3 push mode relative to Merc and Ferrari. That's a massive deficit.

 

I really don't think the likes of Alfa, Haas, Toro Rosso, etc are in the same league chassis wise...If Renault can put the car in P7 on Saturday...with a speculated 20-40hp deficit...

I think the Renault has the grunt. At peak power they seem to be at least at the same level as the Honda, if not better, which I tend to think currently. So on the Saturdays I expect them to do pretty well actually. And Baku seems to suit them too.

 

The reliability remains my main worry though. It's often said that it is easier to make a fast engine reliable, than vice versa. With Renault I doubt that due to proven history. They just don't seem to be able to make things reliable. Which is also why I suspect in races they might not run power levels up to the levels others can. I would actually argue to make it reliable first for two reasons:

Firstly it's far more costly to lose an sixth place race finish due to an engine failing, than run it more conservative and finish eighth. If we want fourth in the WCC, they need the points.

Secondly, you need every lap on track you can. Especially now Renault 'only' run four cars.

 

All that said, it does seem the PU made good strides this winter in performance, even when the reliability is still at the old level. Now ll they need is a new designer and TP  :p

I would imagine this being the first race where they want to run as little drag as possible, that those updates are probably specific for low drag, and won’t be seen again at the likes of Spain and Monaco.

Make of this what you will. Article from post Bahrain analysis suggest Renault down 7hp on Honda who are down 38hp to Merc and Ferrari in qualification modes. Analysis seems to come from ItalianMotorsport.com. 

 

https://translate.go...accate/4362961/

 

Renault beating out the midfield in qualy with a 40hp deficit  :rotfl: . Mind boggling. Just goes to show you where the 1.5 second gap to the leaders is. 0.3-0.5 seconds in the engine easily. Another second in the downforce and chassis ride characteristics....Let's atleast close that engine gap and move clear of the B teams...

Why do they need points? I don't think their WCC position matters this year, if they show flashes of speed that take them clear of the midfield.

Well, that’s true of course. But that might apply to more teams. Alfa shows flashes of speed. Haas does as well. McLaren doesn’t seem to be too bad either. And it’s early days still. To me it doesn’t seem Renault is suddenly better off this year than the midfield compared to last year. It just seems the midfield closed the gap to the big three ever so slightly, but are very much on par with each other points and speed wise. I mentioned the WCC because I think Renault actually does very much care. I don’t think top management would be happy with 6th in the WCC at all. Not even if Cyril can tell the top level management that “we had flashes of speed”.
Now they are tied with Alfa on points. I don’t expect that to stay the same, however, with the continuous reliability issues that haven’t been addressed for years and years, that might actually be in the works. I fully agree that their speed and grunt seems to be improving, but reliability is everything in F1 nowadays.

“Nico and Daniel are top drivers and the car has, at the moment, enough pace to be at the top end of the midfield,” said Chester.

“We want to show that in the next few races.

 

“Daniel was satisfied in Shanghai with the balance and the changes we’ve made to the car has helped him in terms of braking and suspension.

“We have made a step forwards in China, but there’s still a lot more work to do.”

With the unique Baku City Circuit, featuring its long straights and tight corners, playing host to Formula 1 this weekend, Chester also confirmed that Renault would have updates for its R.S.19s.

“Most teams will run a lower downforce rear wing than they’ve run in previous races. There will be a variety of levels with a tradeoff between time in the middle section against the last section,” he explained.

“The main change on the R.S.19 is the medium downforce package with new front and rear wings as well as a small update to the sidepod area.”

[Facepalm]

FYI* both Renault cars lost a lot of HP during the Bahraini qualy because of that mapping problem... 

 

As the datas and the drivers and Prost say; Renault is losing time because of the chassis aero which is too weak in two or three specific areas. The engine performance is very close and the loss there is marginal this year.

 

Renault were best of the rest in China but still almost a second off Red Bull’s pace. While it appears as though the Renault PU doesn’t rev as high as the Honda, this is due to the longer gearing on the Renault; like for like the two PUs are fairly close in this regard. Their setup also appears to be one with significant rear wing relative to Red Bull as with DRS they gain more speed, and are also strong in traction and high speed corners like T7-8. Straight line speed on non DRS straights is also strong, particularly so if they’re running more downforce at the expense of drag as well as longer gears, so perhaps there is more absolute performance the Renault PU then it might appear. https://unendinginsi...ysis/#more-1125

[Facepalm]

FYI* both Renault cars lost a lot of HP during the Bahraini qualy because of that mapping problem... 

 

As the datas and the drivers and Prost say; Renault is losing time because of the chassis aero which is too weak in two or three specific areas. The engine performance is very close and the loss there is marginal this year.

 

Ah I see. Don't worry. I'm sure if you look you'll see I was aware of this at some point in the past :rotfl: . Honest mistake. I forgot...

 

Have still heard Renault say directly that they are missing something in the qualy mode.  So there's still that...No matter how you want to lay it out. The rest of the midfielders have a little more power than we do on Saturday. And we still manage to outqualify them handily in China.

Qualifying telemetry comparing Ricciardo to the two Red Bulls

 

PU seems better than Honda. Ricciardo is slightly faster on the straights once out of the traction zones but is running more wing (gap widens quite dramatically when DRS is deployed).

 

Just need to sort the reliability out.

 

 

Where did that come from?!

 

pretty cool.

 

Ric does a pretty solid job in the last corner, gearing is different I see, but not hugely different. The higher gears are a tad longer that is all. I think corner speed in slow and Highspeed corners is quite down in the Renault than the RBR. I am surprised that at the medium speed turns the Renault looks quite handy (Turns 7,8 and 16).

 

I have to say I don't trust this 100% though, somethings don' add up somehow, specially turns 8 and 9 time lost.

 

Of all the things here, the most critical one (perhaps connected to the lack of high end downforce) is the braking, they really lose in every braking zone the most, the mid corner speed is not so bad. could also be that the engine braking helps the RBR more due to the gearing (but I suspect not that much).

 

Another thing, Gasly is there for the taking.

Yes, the bulk of the time seems to be lost in the braking zones & change of direction in the slow speed stuff (ability to attack the kerbs?). Dan is right, Renault need to put most of their development into the brakes.

Damaged Renault MGU-K that led to Hulkenbergs DNF at Shanghai has been repaired & can be used again at Baku. Grid penalty avoided!

I think the quality of the brake systems are very similar across the teams, as all the components come from third party suppliers (mostly Brembo, Hitco and Carbone Industries). It is also very driver specific, often drivers use different combinations of components in the same team.

If Renault wants to improve the performance under braking, they need to work on how the chassis, aero, engine and brakes work together.

So looks like it was a software issue, that’s good news for Renault, let’s see how the new spec does in Baku.

Doesn't confirm that it was a software issue though. Just hope for Hulk's sake that it doesn't fail on him anyway...

@tgruener
Ferrari rear wing looks huge compared to the skinny wings Mercedes, Red Bull & Renault are running.

It was confirmed pretty much post race, it was in the teams post race quotes.

It was Cyril who said that after the race Hulk's car was ready to go after a hard reset. So this twit from Gruner is a bit stange that they managed to fix the K.

I thought I remembered reading a lot of 'we believe' and 'we think' from Cyril but not actual confirmation of what it actually was...

Exactly - the MGU-K was supposed to be ok after a hard reset was done post-race iirc?

And the video about trying to reset the MGU-K also confirms this. I don't think it was a hw issue.

From AMuS:

 

Then the Rhinelander reveals: "We have another mechanical change in the car, in the same direction as in China, and if that works just as well, that could be a good step forward."

AMuS expanded on that just a little bit-

Renault
Nico Hülkenberg can breathe easy. He does not get a starting penalty. The ailing MGU-K has survived. She could be repaired. Renault has like many teams a new rear wing on the car. It is already the fourth version. "One is coming. That's the Monza wing. The five variants should be enough to get through the season, "says Operations Manager Alan Permane.
The visible changes to the rear and front wing is still a modification to the steering. She speaks less directly now. This calms the car when turning. A first step in this direction was already effective in China. "We are going even further in this direction," reveals Hülkenberg. It's one of those modifications that can be said of: small cause, big effect.
