Hybrid implementation (Regen and boost) is incorrect and bugged in several ways

Additional complaint of the deployment level vs engine power:  https://www.reddit.com/r/EASPORTSWRC/comments/17ol9py/ps5_throttleboost_issues_controller_options/

An additional issue I have is that whenever I lift the gas pedal a bit, even from a 50% acceleration which doesn't even use the electric power, all electric power is immediately removed.

Here is the document which lists what a Valid Regen is for the previous year (pages 124 125).  Grabbed from Reddit.  Note that 5 Bar brake pressure is very low.

The additional complaint from Reddit where the pdf was spotted  https://www.reddit.com/r/EASPORTSWRC/comments/17ppp63/is_the_hybrid_boost_on_the_wrc_cars_actually_this/

"Regen is active if throttle pedal is below 30%.”

Currently the throttle pedal must be at exactly 0%.

”Throttle pedal release will terminate the boost.”

Currently lifting the throttle just for 1% will terminate the boost. To me it doesn’t sound as intended in the doc.

“If SOC >= 80%, at the end of this boost it’s necessary to release the throttle OR press brake to get another boost if SOC is still >= 80%.”

How does that read to you guys? ‘Cos to me it sounds like you should be able to get another boost just by lifting the gas pedal. I guess SOC isn’t known in the game though, as the meter only shows the current available regen boost.

Agreed on the first points.

As for "“How does that read to you guys? ‘Cos to me it sounds like you should be able to get another boost just by lifting the gas pedal. I guess SOC isn’t known in the game though, as the meter only shows the current available regen boost."

Technically this doesn't matter to us as we can be assumed to be driving under SOC 80% especially after launching.  I don't think we need to worry about this at all for this game version. 🙂

To add my 2ct to the good explanation above and included the link to the official document.

The implementation of boost and regen in EA Sports WRC removes the fun of driving a Hybrid Rally 1 car. You have to lift the foot completely from the throttle pedal (or add a whole bunch of dead zone) also the regen is very slow and needs lot more brake pressure than in the regulation defined.

So we would have to over-brake each corner to get an amount of regen with the throttle foot complete removed from the pedal. 

The regulation (last updated version from the FIA site 2023-04-28) says on page 115:

4. VALID REGEN
• Maximum throttle pedal is 30%.

• The regen energy counter is active only when the front brakepressure is higher than 5 bars and the throttle pedal is below30%.

Link to the PDF of the regulation: 

https://www.fia.com/sites/default/files/wrcsr_2023_2023-04-28_green-blue_0.pdf ​

This means you have to lower the throttle under 30% but not 0% and have to break (5 bar is a very low brake pressure). If I look at the onboards of Rally 1 the regen is completed nearly in every corner while the driver only lowers the throttle and has boost out of every corner. 

The implementation in EA Sports WRC is nothing compared to this. You have to lift the foot completely from the throttle pedal and the regen is very slow and needs lot more pressure than in the regulation defined. 

This definitely removes a lot of driving fun from the Rally 1 cars.

There is also a total limit to the energy available, so you could get to the end of the stage without any more hybrid thrust. The 80% limit would become either an advantage, because you would get the boost on more accelerator presses, or a disadvantage, because it forces you to use a boost part that you could accumulate in more suitable parts of the track.
There is also a button to disable the hybrid, with the limitation that once reactivated it will only be active after 60 seconds.
If it were implemented as per the regulations it would make the use of the boost very strategic.
As it is now it's just a useless distraction from driving. I'm much faster if I force myself to ignore the boost bar.

Update from the devs on the patch 1.3 out now:

To clarify, prior to Version 1.3 the power unit would only charge when the throttle was at exactly 0%.

This has now been changed to be any throttle value below 10%.

This should now make it easier to recharge if you're resting your foot on the throttle or have your pedal calibrated in such a way that it doesn't stay at 0%.

Edit: so hopefully we can get this ammended to the FIA set 30% whenever the rest of hybrid gets fixed up

Quick Summary after the new patch and some driving:

1. Cautious setting 70% throttle threshold is way too low to allow control/drive out of corners without Boost.   (either engines need more power down there, or increase this to 90% or 95%)
2. Boost is 1 or 0, should be linear increase  after throttle threshold to WOT
3. Max Throttle is now 10% for regen to be active, should be 30% as per regs.
4. Regen should be active under VERY low front brake pressure, 5BAR = about 75PSI (out of 800+).  Currently seems to be a much higher threshold.
5. Handbrake seems to kill boost, so entering a HP, you regen under braking, use HB to turn in, and you lost your boost event!
6. Boost kicking in and running out should have a smooth transition.

You can pretty well observe the result of the above 6, EVEN with 50% balanced threshold setting, only 2 or 3 boost events total in this ~17 minute stage  https://www.youtube.com/watch?v=hw_UqAISZlI
