2019 Azerbaijan Grand Prix - Baku, April 26-28

Leclerc doing a an old school throttle under braking or is it the Ferrari ECU?

Maybe because more regenaration. If you have enough fuel it is logical ( at least level of my knowledge )

ham vs ver
verstappen did his best lap on his first flying lap, compared to many other drivers, most of whom improved a lot as they did more laps. Verstappen was unable to do so as he did his quali run a bit later on and got stuck in incidents from other drivers, preventing him from doing more runs (If I recall correctly). Even so, he gains a few tenths in middle sector here on hamilton, but loses time on the final straight (~2.5 - 3 tenths).

at one point they are almost equal

but then you see the power of the mercs

Is not all power Mercedes are effectively running without much wing like Renault

Dang Bottas hit 344 kmh and engines are turned down. Wonder if he got a draft. What's that about Ferrari straight line advantage?

344 km/h was with slipstream. That’s pretty obvious.

Yes, But Vettel & Leclerc also had slipstreams on a few laps and couldn't better Bottas!

And I didn’t claim that. Just pointed out that it couldn’t be more obvious that such a speed with detuned engines could just be done with the help of slipstream.

Ferrari rear wing looks gigantic compared to Mercedes

Bottas did while doing a fast lap on Mediums and getting a tow practically from the beginning of the back straight from a Renault (he actually made the pass even before he opened DRS).

The times from FP2 are very misleading, the conditions played a big factor with a very green track (with the drivers that chose to do their quick laps later in the session benefiting from track evolution, like Kvyat or Sainz)... It was a very busy session also, therefore a lot of cars didn’t had the luxury of trying to get in the right track position... This slowed some (Ferrari was stuck behind Alfa Romeo for a number of laps) and in other cases it helped some teams (when the tow worked in their favor).

If usually FP2 times aren’t representative of actual pace, this particular session is even less representative than others... The teams really don’t know where they are in relation to others.

This strikes me of 2017 where it looked close in practice then Merc blitzed it. I think it'll be close in qualifying but Hamilton on his race run did a couple of laps in the 1.46s that are massively quicker than anyone else, showing their potential. They probably wanted to do that to confirm how much they'd gain when they turn it up. Plus when track rubbers in they'll gain time comparatively I would imagine in the corners.

Yeah, something's fishy! Usually, on race sim they are at least 5 to 6 sec. per lap slower compared to qualy lap.
And now delta time is somewhere between 3 and 3.5 sec (1.43,5 Lewis`fastest lap to 1.46.6/1.46.9 race sim) ...

Clearly, it's kinda trending this year for Ferrari to run in higher modes on Friday and Merc to crank down the power as we could see after 3 races so far ...

the fuel effect is not particularly high in Baku. Renault doesn't give out that information in their new fact files anymore unfortunately, but last year's one stated 0.34s per 10kg of fuel:

So those 3.5s you mentioned above more or less fit as the difference between an empty and fully tanked car.

I believe the difference is more related to relatively slow “Qualy Laps” than fast race sim lap times... The track was dusty and not rubbered in when teams when for their fast laps... Considering track evolution, it is not surprising that the race simulations were relatively quick

I for one am glad that the two free practice sessions were a bit confusing. There were a lot of incidents red flags etc. I'm hoping most of the teams did not get as much data as they would have liked for setting up their cars for the race and qualifying. I think that will be a nice think especially for the race with the car's not being super dialed in. That will separate the wheat from the chaff.

lec vs ham
interesting how much more speed leclerc gains with drs compared to hamilton who barely gains any, but has much higher speed prior to the last drs zone of the lap. Makes sense as ferrari runs visibly higher wing levels.

Lec gained much more at the main straight when DRS is activated. Aside from a bigger rear wing, looks like it also has something to do with that Lec saved ERS for the main straight. Before turn 1 his speed dropped from 325 to 320 before braking. Lewis on the other hand stayed at 329 till braking.

Maybe Mercedes was testing different ERS mapping?
