We're talking about where they can be closer to the fastest car, not where they'll be in the overall pecking order. Their top speed was 319 kp/h whilst having less performance than RB in the high speed corners who were hitting 323-325.

I agree that Bahrain is a power circuit relative to most, that's part of why AMR are so good at Bahrain. The straights are short enough such that it doesn't make that weakness so obvious
You also need to take into account the unusually short gear ratios on the Merc (and AM). It's a benefit on the 3 shorter straights since they can easily push eight gear whilst RB stays in 7th, but it's a negative on the long straight.
I don't think the gear ratios are making nearly as much difference as aero :D The AMR car has to be weak in some places otherwise it would be the top of the timing. Reality is that its efficiency doesn't match up to RB/Ferrari who have been in an efficiency development race for 12 months - it's not surprising
The gear ratios are an underrated aspect of each car, especially when looking at end of straight speeds on long DRS straights. RB runs a pretty long 8th gear, and Merc has one of the shortest. This usually evens out time-wise over a lap but can impact speed trap results.

I also think the AM ran slightly more wing, their wing is very comparable to the second wing RB tried in testing, the medium-high wing.

Well the AM is not as fast in high speed corners, it doesn't have as much floor DF.

Yes they ran more wing (consequently more drag) and still don't have the most downforce.. less efficiency

That's all I'm saying.

This lower efficiency will likely cost them (along with whatever minuscule difference gear ratios will cost) at tracks that place a greater focus on efficiency

It might compared to RB, who seem to be masters of efficiency. But AM is not far off, 319 isn't bad at all with that wing and those gears.

Again this whole exchange begun because someone said amr should be closer at other tracks. But I am pointing out Bahrain already seems to suit their car very well based on its characteristics. Short gear ratios makes Bahrain suit them even more

2 laps won't make the difference so not sure what ferrari is trying to achieve here
Mercedes AMG + Hamilton => dreamteam!
If you can't beat'em, call Masi!

It's not bizarre. Every single lap your tire is 2 laps younger, adding up to a lot of laptime across the stint. It's worth seconds across the stint to have a fresh tyre vs a tyre that's had a hotlap on it.

That's also because doing a hotlap is a very aggressive introduction, whereas pirelli rubber wants to be introduced gently at the beginning of the stint. Tyre preparation is important.

Yeah that blog/site has bizarre understanding of the sport for sure :lol:
And they call it a stall. A STALL!

Fresh tires are 5s better in the first stint than used. They would be 5s slower if they had no new tires. Not sure what RBR situation matters at all in this. Ferrari strategy makes sense, was agreed upon before quali, both drivers agreed to it. LEC said in the interview that he agrees with it and it's a good idea.

Presuming the deg is identical across the 2 cars.

The RB might have 2 lap older tyres which might cost them a fraction lap time, but the car chasing might hurt its tyres more, so the offset becomes less.

Sainz didn't stick to it, though. Probably because his first run in Q3 wasn't good enough?

Yeah his lap wasn't good enough to be in front of Alonso which clearly was one of the minimum goals at play here. LEC said that ALO has faster race pace so having 2 Ferraris in front should help a bit, especially with the better top speed of the Ferrari. It will definitely be a hard race for us tomorrow.

Question to those who possess the knowledge: Is a fresh tyre worse at lights out? Is a slightly used tyre better at getaway?

Fresh tire is better all the time unless you run the special brand of Michelin tires from 2005-2006 designed to specifically increase the size of the contact patch after the first few laps, totally against the rules but Ferrari was too strong.

talking about it, interestingly, Aston Martin seems to have given up on rubbering in tyres. I didn't notice it this weekend at least
