RIC DNF is because of the damaged bodywork.

The super-dyno is only operational since mid February so it came a bit too late for the new PU. So the spec b and the following specs should be the first PUs to really benefit from it.

Regarding power gains, all the Renault-powered cars have interestingly gained 10-11km/h here compared to 2018 qualy. (while STR gains 7-8kmh and RB 5-6) But Hulk had an electric problem in Q2 (a chassis one according to Permane)

Regarding winter testing, Mclaren has probably used two engines. So the first one has probably ran atleast the distance of 5 Spanish gp races and the second 8 races.*
The first Renault engine should have done around 5 races while the two others 9,5 races together (but in which ratio?)...
Some of those engines were experimental.
*the first one ran for the first two days, as planned.
And AFAIR Renault did a similar thing in 2016 and one of the PU covered the distance of 8 races (not gps)
And I dont think it's necessary to do 7 grand prix with a PU if the track/dyno/super-dyno datas are reliable.
The super-dyno is very new so they probably built special PUs with special features and extra sensors to work on the calibration and the correlation.
In 2016 too Renault had to work with new dynos to them; the Illmor ones.

It’s a little bit discouraging to start the season with a PU failure (MGU-K)... Hoping that they got that out of the way and if it had to happened, it was in a race where the result wasn’t expected to be good... Still wondering how both teams (Renault and Mclaren) will perform in a more traditional circuit and in the fast ones as China.

It will be interesting to see.

But top speed were goods in testing.

Also you have to keep in mind that bad chassis, with bad traction, always have a bad top speed nowadays.
So it will be once again difficult to juge Renault engine.

They also just have their new dynamic dyno, so I think they will unlock more power this year.

I seem to remember somebody posting how the Renault engined teams didn't improve between sessions which seems to validate this theory... apparently HAAS the same maybe Ferrari as well. Could shuffle things up in Bahrain.

That’s speculation derived from comments from Cyril saying that Hulk had a drop in performance in Q2... I don’t think it means that they used Quali mode, but if cooling was an issue, it would have had an effect on performance.

I think I heard somewhere shortly after qualifying that Nico had an "electronics" issue, don't know what the interpretation of that is.
Cyril also mentioned during their Bahrain Grand Prix preview that they need to show the improvements they've made on the engine side, suggesting that they have more than they showed in Melbourne?

In its last interview with L'equipe Abiteboul said that they have this MGU issue since testing.

And they have developped a fix... The fix was given to McLaren because of AUS failure.
Renault works team didn't had it in Barhain

So that may explain the issue, on the other hand, there is no way to be sure that the fix will be reliable.
Let's see in the next races

Diferentes mediciones en pit y paddock en cuanto a potencia d motores. Todas coinciden en Ferrari claramente delante d Mercedes, pero no atrás. La q me ha llegado da a Honda más potencia q Renault en carrera y menos en quali. Otra da a Renault por delante en ambos. Muy igualados.
