Merc and Red Bull engineers have indicated the Merc race pace advantage was around 0.15 a lap.

Gap divided by laps? They probably extrapolated the time without a 2nd stop and Max should have been some 10s behind in the end.

You can’t do that with drivers running completely different strategies.

Only point where you can really compare it is the first stint, and since Hamilton kept up despite dirty air but couldnt go faster once Max pitted those 0.15 s seems to be about right.

Still seems a wild stab to me. 0.15? Why not 0.3? Or even 0.5? After Max pitted, all comparisons are out the window. Lewis might not have gone faster because he was preserving tyres.
I am fine believing actual data from the teams, but this is just guessing in my opinion.

If Hamilton would be 0,5 faster, he'd most 

 

a) pressure Max more instead of staying within 2 second

b) he'd be faster the moment Max pitted, because he was driving 0,5 slower than his car/tires could handle for many laps and should have some extra speed. Instead, when Max pitted, Hamilton's laptimes actually also dropped / stagnated.

Excited for the new line up and the engine/car upgrades. I still think 5 wins is doable :)

Nothing really. The interviewer mumbles something about whether going aggressive when they first entered F1 has paid dividends in the long run, to which the reply is ‘(you mean) size zero?’

What is interesting is how much the PUs are a work in progress after they are introduced. They say that Honda were disappointed with the spec they introduced in France where the increased power didn’t seem to manifest itself in improved performance with MV losing out to Leclerc at the start and Gasly to a Renault later. He says they had problems with the heat in France which they set out to address to maintain performance in hot conditions. A few weeks later this paid dividends in Austria.

There is a lot about Austria and what it meant to Honda, also about the podium where Tanabe was presented an award by Berger, the guy who he used to be a race engineer for and is a longstanding friend with.

Also a lot of positive stuff about RBR and what great partners they are.

I think this is what sets them apart from Renault. Not looking for excuses, but just working your ass off to solve problems.

Renault would've probably blamed RBR for not providing enough cooling.

I would be extremely surprised if Renault and the rest weren't doing the exact same thing as Honda, evolving the way the engine is used from race to race.

Honda and Red Bull are a good match.  :up:

Of course, but Honda have been refreshingly open (as below), compared to the boring secrecy of Renault, Ferrari and Mercedes.

Of course, but it works differently when you're not a works team and have less shared responsibilities.

I also don't get this hide and seek from Merc, Ren, Fer. I think it's quite hard to "steal" some secrets from pictures. I mean it's not like they have to show us piston design, cylinder head,...
But instead they should be proud of their technical masterpieces and show their products to the community.

The new Honda engine is expected at the next race? Grid penalties then anything from 5 to end of the grid?

Lap time comparison suggests 0.3 is the the most realistic (looking at the laps on tyres of similar age, with both needing to push and not too close to one another, delta then disappearing when running too close).

Probably Monza.

 

But this article suggests there may be another engine update at Sochi to prepare for Suzuka and in that case introducing an update at Monza means it will only do two races. So perhaps for that reason they may decide to go for a Spa update.

it is also for pooling engines, they seem to have a Suzuka delight in preparation. Don't be surpised Albon gets a fresh unit to 'test' for Verstappen in Spa and Verstappen gets one in Monza.

It’s hard to say. It’s easier to pass in Spa than in Monza, but RBR Honda might be the best package in Spa, so you don’t want to give up on a potential win for a PU change.

Depends. If a good result on Suzuka is of vital importance to keep Honda in F1 after 2020, then that should be priority if you ask me.

Interesting piece on test benches. It has Max hinting at having not enough engines to test when they were a Renault customer. Now with Honda they can test for longer (Honda provide more test engines) and that improves relibility of other parts as well.

https://www.auto-mot...verlaessigkeit/

Used google translate:

Max Verstappen reveals that indirectly the engine partner was also responsible for the damage in the chassis area. "Today we can drive much longer and more intensively on the test bench. This allows us to test all components in continuous load at the limit. "
...
The secret: Honda provides many more engines for test-bench trials, and they can be driven there with more power, ie under realistic conditions. "You also have a lot more test benches. In Japan, there are test facilities for all sorts of components, "reveals team boss Christian Horner.

Yeah but they already had the VTT test bench when they were a Renault customer. I guess it must have added to the frustration that they couldn't get enough Renault engines to test what they wanted to test.

Good points A3. 

 

When you think about it, it's quite remarkable how much more reliable RB has been this year regarding non-PU issues. 

 

Last year there were quite a few gearbox issues if I remember correctly, and also drive shaft issues etc.

Yeah it’s amazing. They can just tell whoever is in the sim to extremely attack the kerbs over 10 laps at Spa for instance and they can record those 10 laps and just let the sim repeat it over and over again until parts break.

I reckon the only technical DNF from Gasly was when he scraped/hit a wall? He had a driveshaft failure, quite common on street tracks when some tail wiggling can do damage.
