Interlagos 2021 Pre-Race Thread

Right. What’s the purpose of those grooves anyway—water drainage?

 

Yeah.

I forget which track had this as well and it led to cut tyres. Spa maybe?

 

With volvos report comparing their cx40petrol road car vs their cx40 hybrid and electric versions, and total emissions in its lifetime of use. The electric version was 70% more emission costly to build and IF being run on 100% emission free electricity (though if wind energy this doesn't count towards the build off wind Mills ans getting rid of them, which totally erodes all energy they created in a best case scenario), it takes 35000 Miles for it to be on par with run of the mill petrol (including the carbon cost of drilling oil, refining into petrol and transporting it to petrol stations).

Clearly the expensive in case in part is the cost of mining, transport the battery. I don't think it accounted for the recycling of battery mind you.


Now this leads to an interesting discussion: how green is F1 new engine really? They use 2 battery packs a season minimum. They get charged between sessions and of course charged by an f1 for as long as it's on track (at a rate of 2mj a lap). With the added weight (25kg battery, electric engine, mguh etc), cost of charging (is it still purely from harvesting lost energy?).

Someone with the knowledge could shed some light on this.

I don't think the current f1 engines are as green as they tell us they are.

 

Awesome stuff. But let's hope he doesn't eat it until after the race!

Neither Senna nor Lauda or Prost ever needed to refer to so-called Idols.
Simply because they were men and not immature young boys unable to exist by themselves.
I think Mark Webber had already noticed that a few years ago.

 

Autosport headline:

“Why Vettel visited a former F1 midfielder's Brazilian farm”

Why? I don’t know—didn’t bother to read.

 

Thereafter, Diniz’s attention shifted to his Brazilian homeland and included the creation of an organic produce and dairy farm. And it is that latter interest, rather than what he did in F1, that prompted a visit this week from four-time world champion Vettel.

The German, who is taking an increasing interest in environmental issues, wanted to understand more about Diniz’s farm as part of his education.

“I think it’s a very exciting way of doing agriculture,” explained the Aston Martin driver.

“I was happy to have a look at his farm and learn about it: learn about his path, what he’s been through, and learn about the idea, the objective, and his intention.

“I think it is very good and very forward-thinking, and something the world needs. It’s a very honourable job to supply the world or supply people with food, and doing it in a responsible and regenerative way. I think it is a great approach.”
