Interestingly he doesn't fully drain the battery at the end of lap. around 1/6th remains.

very "conservative" at the top of raidillon

How do you know how much battery is left?

Hey Juzh, yelistener from youtube.
Last year's summer break pu upgrade was really good. In quali they reached the same BSP1 speed as 2016 (in races before spa it was usually 7-10kph lower). Probably will not be the same this year as top-speed-wise 2018 dropped quite a lot comparing to 2017.

Halo added lots of drag, also some weight.

Yeah the halo added about 1 point of drag, a fairly insignificant amount compared to the total of the car (or about 5kW or 7bhp or Power at 300km/hr which is a smaller deficit than the power gain from the PUs since last year). Cars have been quicker around most tracks this season (excl' Azerbaijan and wet) by between 0.5 and 3s - which indicates a lot more downforce, hence more induced drag.

They also have fewer power units for the season now so they have to be more careful in practice and races with the engine modes and ERS deployment. The difference between fastest quali and fastest race laps this year has typically been 3 to 4.5s, which is all about PU management. They do a lot of clipping, where they get to a constant RPM and speed then just stop accelerating, which is balancing the MGU-H charging, fuel flow, lap-time. All the teams are doing that between Paul Frere, Blanchimont, and the chicane here in P1 and P2.

I was talking about qualifying where the 3 pu is less relevant. Azerbaijan in particular comes to mind because if you compare 2017 vs 2018 pole side by side, the 2018 car loses around 0.8s in the final straight. I've seen troughout this season top speeds have dropped somewhat compared to 2017 and there really isn't that many other reasons apart from the halo adding drag directly or indirectly trough DF loss and having to compensate with dirty and inefficient downforce. I could be wrong ofcourse, it just seemed sensible.

Advantage for Ferrari in high speed S1 & S3.
Merc stronger in S2 probably running more wing.
RB's mini RW compromises them heavly in S2.

Expecting a Ferrari Pole with the engines turned fully up.

Looking at Mercedes’ RW compared to Ferrari’s, I would say yes.

Bottom of the steering wheel. Probably because they have a 4MJ deployment limit from the battery per lap. This should show that the battery SOC is not the same as the per lap SOC, or the ES->MGU-K SOC for that matter.

Thanks.

Looking at regulations they state that every driver that reaches Q3 must start on his Q2 tyres. Will bottas need to start on used sets at the back?

[Sierra117]

How the heck did dabbing reach F1 ... what is happening ...

[Sierra117]

919 Evo record has been surpassed by Kimi (so far). Within regulations. Take that! :p

[Just_a_fan]

F1 running to regulations retakes the lap record from Porsche and their non-regulations "special". And does it in Q2 suggesting more to come...

[Sierra117]

OK now that we've retaken the record, let it rain, let it rain, let it rain!

Rain falling. Hamilton pole?
