WRC Testing

[stefanvv]

Btw, isn’t the criticism on ’17 cars a bit over the head?

Till recently everybody felt WRC cars were annoying and they should be replaced.

Yeah, they should have been replaced by segment D cars. Now I'm trolling.

dont listen it with your headphones, you will be deaf

What are You talking about? It is on different planet with different gravity (possibly a black hole nearby).

For the competition and more drivers to compete to each other R5 should be better. Agree with Mirek on this.

The increased risk with higher cornering speed is indisputable as it's pure physics and near non existent strenghtening of the body (the prototypes seem to have pretty common rollcages) makes no difference in comparison to the kinetic energy growing with a square of speed. On the other hand I am quite sure that the works drivers can handle it.

Divided by 2 to be more precise:

This is the graph of similar weight vehicle (Tesla roadster):


So if we take an example of speed increase from 100 to 110 at some corner, which seems realistic, that's about 0.03 kWh. Can't the wider and strengthened doors handle to swallow it? The rollcage is the same ok.

Stop it already, enough.

I don't think it's a case of if they'll swallow it. It's a fact that the impacts will be bigger, since the cars will be quicker. So there you'll have more danger to hurt someone.

IMHO the cars should drive more spectacularly, not being quicker in the corners.

What matters is the change not the absolute number which tells You exactly nothing (I am sure You have no idea what structure You need to dissipate 0,03 kWh - so have I). In relative numbers a WRC car with the crew going 110 km/h instead of 100 km/h has 21% higher kinetic energy and that is what matters.

Anyway we are way off topic and I agree with Rally Power that the safety factor is pushed way too far in here especially since we have no relevant information. Throwing some bullshit numbers around and acting like we know what they mean is good for nothing.

Fast forwarded videos like this - https://www.youtube.com/watch?v=G-1f-_Z58GE aren't good for something either.

Never usually stops anyone on internet forums though!
