2021 Engine thread

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Perhaps they have included the words "recovery mode" to try and prevent the use of the K as traction control? How they would police that is beyond me..?
It would still be recovery. Besides it can be only used as traction control if somehow it would affect the wheels differently in a particular way, which you can't accomplish with a motor connected to the crankshaft.
Can you please explain how a +/-120kW motor permanently connected to the crankshaft can't be used for traction control?

Shouldnt F1 have allowed more open rules for 2021 while just keeping the 105 kg and 100kg/hr rule?

This could have encouraged the Porsche V4 (with some development) to be considered as an works or customer option

Nope! :lol:

I was thinking more about torque vectoring rather than plain wheelspin protection. Anyway, if it could be used for that they'd do it now, which is obviously not the case based on the many examples when the driver spins the wheels and looses it.

They only have max -120kW of sneaky TC, and then only if they haven't recovered the full K-recovery amount for the lap. Either way, with over 600kW of boosted ICE power on tap there are still plenty of opportunites to spin it up and lose it.

If I remember correctly only the stored energy is limited, so they could still use the kers, they just have to waste that power in some form of a resistor.

Now you're thinking like an F1 team!
There are the rules and there's a box. There's always a lot more space outside that box than in!

May or may not join is right, but F1 loses nothing by relaxing a few of the conditions which were put in place as a cost measure for existing manufacturers. With 7 years of development the existing manufacturers are not disadvantaged in any way.

In the current scenario where manufacturers are facing a downturn and a shift in technology towards pure EV, what is wrong in keeping the door open.

Like hell they aren't. All of them need to re-design their PUs from almost square one if you make notable changes. Allowing 4 cylinders and different displacement would be such in this fuel limited era AFAIK.

If they allowed V4s every manufacturer would switch to them to minimize internal losses. Any change in layout would cause havoc as they all scramble for new engines.

I doubt they will return the HDi FAP V12 diesel...

¿Are the same engines like now the engines in F1 2021?

Essentially, yes. Only the weight increases, and the material usage is restricted as a cost cutting measure.

And a higher percentage of biofuel, which will mean less power
