Just why? What's the point of all that?

Again and again they spend time and effort on rule changes which are completely pointless and bring nothing for the future of the sport.

A question which DF can not answer.

I understood that the main issue was overcharging of the battery. It can be charged and drained only up to certain current values depending on its capacity. Some circuit cars use supercaps instead of...

I think you undersestimate the deceleration value a lot. Let's say you need to slow down the Rally1 car from 150 km/h to 100 km/h on asphalt (from 42 m/s to 28 m/s). The car has around 1400 kg with...

After some discussions on this topic I realized that the total capacity of the battery is what limits the recuperation power to a relativerly low value like this.

I expected a lot more to be honest. That means that the braking effect will be also really small. For proper racing braking you need values 10x higher or more I guess.

That's true but it also removes the possibility to control the shifting by the ECU. Honestly I have no idea how the WRC gearshift system was designed but I would expect that indirect shifting by the...

I'm known as a no fan of EVs here on the forum but this is actually a great thing because one of the major sources of polution caused by the vehicle traffic is the dust from the brake pads.

Not only that. It also doesn't make sense from technical point of view. The time to reach the top speed from standstill is probably around 15 seconds. You don't need any extra boost to keep the top...

The regen of course slows down the car, it can not work other way according to the laws of physics (you take away the kinetic energy of the car and transform it into electricity). It helps to the...

Sort of... I'd say the awkward rear bumpers are made along an idea like this: "Let's make the best diffuser which doesn't look too much as a diffuser."

Man, please aducate yourself in basic physics. Your questions make no sense whatsoever.

First kW or Hp is NOT a unit of energy. It is a unit of power which is a different thing. Power is a...

I meant only simultaneous braking and pushing the throttle. Sorry if I was not clear.

I remember that already in the era of the fully active 2.0 litre WRC they often said that left foot braking isn't needed if you set the diff maps right (at least on asphalt). After all the left foot...

If I count right in a veeeeery simplistic linear scenario a 300 kW recuperation would be able to slow down a WRC car from 150 km/h with a deceleration of 1,5G without using brakes at all.

If there was only one short braking in the whole stage than the recuperation would make no change but there is a lot of braking. Every braking generates heat. The harder you brake the more heat you...

The thing is that with recuperation you can brake harder and later when there is enough grip. The recuperation takes away reasonable part of the energy which would otherwise transform all into heat.

If I remember right Jan Skála, who is a supplier of carbon parts for all WRC teams, said in an interview on ewrc that they were all using spaceframe.

By the way he said his company in the last two...

IMHO they do the things way too complicated. As if the rally rules weren't complicated enough already without that.

That's more or less the same as pre-2017 WRC cars, isn't it?

That's one thing which puzzles me. I simply don't see any meaning in doing so. Why limit suspension travel? The impact on the cost is probably marginal, it only makes the cars harder and riskier to...

They are not completely stupid. They would not carry the hybrid system and invest huge money in it just to use it only on the road sections. That would be just a ridiculous nonsense :)

I guess that you still need a homologation done by the manufacturer.

On the other hand I think that WRC will need to allow (and should) privately built cars in the future in a similar way to...

It's early days. Let's see how it behaves in January ;)

It often happens with Yaris WRC on asphalt.



He meant that the car often goes on three wheels in sharp corners lifting the inner rear wheel like a typical FWD.
