Group B rally cars had to be street legal (or have special permits), between stages they drove them on public (open) roads which would suggest the handbrake wasn't removed. Part of a 4wd (AWD) vehicle is a centre diff which were open differentials meaning the front wheels could spin at diffent rates to the rear. Think normal RWD vehicles, jack up one side and the wheel can be spun freely. So why then would pulling the handbrake lock the front wheels also? Possibly the centre diff was locked, but that'd cause a lot off stress on drivetrains when run on dry tarmac stages. I've owned many, many cars a few of them AWD and one 4WD. Only one of these had a fluid assisted HB, yet all responded by locking the wheels the HB was attached to and only those wheels.The exception being the 4WD (with 4WD engaged) because it had no centre diff. Now I've watched more than my fair share of Rally footage focused mainly late70's- early 2000s and except for one case the drivers of Group B AWD vehicles didn't seem to use the handbrake.

Ther's a good chance I'm a blubbering idiot with no clue, if so please explain to me why we can't use what was most likely available in the real life versions of our digital toys? Or explain why they weren't available or able to be used..

It is because the first AWD vehicles did not have open center differentials. The fronts and backs always turned at the same speed, because the technology was new.

Locking the fronts or rears would lock the other side as well because it was a "primitive" form of AWD.

So they'd lock the centre diff by welding it (for example) and run like that? Makes sense, possibly helped cause all the transmission failures. So much torgue put thru a locked drive train on tarmac where there's no chance of wheel slip, would be a tad stressful on the drivetrain.

"edit" I hope no one starts a "Remove centre diff's" topic as well, that'd be fun to drive...

It doesn't teach any bad habbits because.

1. It's faster to have use of handbrake as it works right now.
2. Nobody is using Dirt Rally to learn to become a Rally driver
3. Even if they did, Group B ended 29 years ago.

It would be more realistic if they had no handbrakes, but lets not overstate the relevance here.


spot on mate well said,can't quite understand the whining about having use of a handbrake
on the group B cars, just don't use it it it bothers them so much,


next thing is they'll want everyone to use H pattern shifts on everything that have them

Worth mentioning, on another thread discussion about the game's restarts, some people suggested that OP should have self control and not use restarts if don't like them. So, the same thing should be applied to the use of handbrake. Talk about double standards.

Just leave the e-brake where it is. Options are a good thing.

we are driving historic cars with modern technology obliviously...

seriously, if u asking for pure realism as someone said they should remove driving assistance from all cars except rx cars and 2000/2010 cars with abs only from '90 maybe (i m not an expert but u know what i mean)

this means realism but also more difficult for new DR players

Like I said before:
I would be nice to have a "soft lock" option, like we have it for steering.
Also for shifters this would be very nice, but that has already been posted in other threads.
No one said it's a big deal, simply that it's worth mentioning. OP was just enquiring about the state of the real Group B cars.

You have to realise that while this kind of nitpicking might not be for you, without it you would be driving cars that all felt the same. Someone has taken the time to research the power differences, the drivetrain differences, the number of gears, the list goes on. And these things have been accurately implemented to allow us to enjoy a taste of what these cars might have been like. Even if it's a virtual taste that can never come close to reality it's this research and mind for details that has allowed it. With this in mind it makes sense to mention the things that stand out as different from the real thing. It's not just whining, it's a continuation of the mindset this game is based on.

If it's not for you, that's fine, just enjoy the game. But don't come in here and talk ♥♥♥♥ because people want to contribute to the realism that has underscored the project from the beginning. This is early access and it's what it's here for.

+1)

It would certainly not harm this game to make things work as closely following the real-world functionality as possible. So why that would mean to actually provide for a handbrake on most group-B cars: that would then need to act like the real thing: thus not be of much use - handling-wise - in the case of the early AWD cars.

@rs200wrx(Trev)
any answers yet that you could share regarding the source you have?
well all those out there wanting reality, but no one notices the manta and mk2 escort has the wrong type of rear suspension. Both have an independant setup and not the big live axles they are supposed to have.

Not exactly, at the time they only had mechanical LSD that used clutch packs. And they used that type of differential for all of those installed (front, rear and center).

Viscous, torsen and others did not exist at the time or were too expensive to be pratical to use.

Mechanical LSD tended to fully lock when the difference was too high between the two output, which included the center differential at the time. It meant that if you pulled the hardbrake, the 4 wheel would slow down at the same time, if not all lock up depending on how much pressure was applied on the e-brake. It meant that it was impossible to use the e-brake unless you wanted all the wheels to lock up.

In comparison, Group A cars used Viscous Coupling in the center differential(with exception of the Celica ST165, which used a manual lockable center differential, and the pilot or copilot usually deactivated the lock on asphalt or when there when they knew they needed the ebrake), which permitted to use the handbrake without much problem, with the only problem of added wear on the coupling.

They probably had the e-brake installed in the group cars, but was probably only used for parking the car.

BTW, fun thing to know : the current WRC cars, does not have a center differential. Instead it have a transfer case, and they use a clutch pack between the driveshaft and the rear differential to disconnect it when pulling the ebrake.

Group B cars did not have that at the time because probably it was either too expensive, too complicated for the time, or they just did'nt think about it

I wouldn't necessarily remove it altogether, as I can already see the flood of bug reports that the handbrake doesn't work on 4WD cars. Best option IMO is to just put it as a driving aid and give the option to disable it with a bonus like the other ones.

Agree this is the best solution. Turning The driving aid off should revert its operation to how it is in the real world (lock all 4), as this is preferable over it doing nothing at all.
leave my hanbrake alone thank you and leave t16 alone in genreal gitz

Thank you kind sir/madam for that insightful explanation. I've been searching on and off for a while trying to understand why they (Group B) never seemed to use the handbrake to initiate a slide. I owned a Pulsar GTI-R and quickly discovered combining a corner with a little bit of handbrake and a LOT of throttle equalled stupid grin whilst (mostly) keeping to the speed limits. Anyway thanks again for clearing up that knot of confusion I've been stuck with.

good find. That would need "fixing", then. Especially since that is such a crucial property of both cars, defining a huge part of their "soul"!

Who cares, it's easy to drive these cars with assists turned off. You would have to have severe learning disabilities not to figure it out.

See how many people acctually drive with assists disabled and learn it's a non issue.

Accessibility shouldnt even be an argument these days, This is a PC game on Steam no doubt. If you can figure out how to buy, download, install and start the game you should be able to figure out how to drive these rally cars.

More realism and you will protect the legacy and raise the bar for other games.

No problem

The pulsar had a viscous coupling, like most Group A cars of its time (from the very late 80s (88-89) until the end). Which explain why you where able to do that :P

They were in development at the time of Group B, and I'm sure that if it was not canceled, the planned replacement of Group B, Group S (check Toyota 222D and Lancia ECV for examples), would had used viscous coupling instead of mechanical LSD differential for the center differential
