Quote from Polaxis :

Thank you for the videos. Ok, I already knew them, but thank you
I saw a video of an S4 on Pikes Peak but perhaps it was with a private driver and not with the whole support from Lancia (compared to AUDI and Peugeo who send many people to the U.S. for this race).

I don't have Richard Burns Rally but you can drive the Austin Metro in some Colin McRae too
But I will ask some friends if they have it so just send me the link.

Btw: I heard about that the rules of how a rally stage should be were changed with the introduction of the WRC.
Now a rally stage shouldn't exceed the average speed of 120 km/h?

It is correct that the average speed has a limit now. Several stages in the Swedish rally have been shorted just because of this.

The reason so few games have the S4 must be that it didn't exist for very long. It was the last of the Group B monsters to see daylight.

Quote from z3r0c00l :

I would be extatic for any BMW road cars, but especially the following.

The first M5
new m5
z4
X5 for rally
M6 seeing as it's up as a prize for the LFS/INTEL road trip comp
316 coupe
330 (older version the newest one is ugly due to the stretched front lights)
Works Mini
850 turbo
BMW 633 CSi (1986)
A diesel, I want to see if all these diesel owners are right.
Hartge 1 Series http://www.auto-adrenalina.com/bmw_1_v8.html

All these car types are already represented in LFS. Apart from the X5, which can't be a fun car to race with. High center of gravity and so on.

And I'm quite certain that you can adjust the setup to make the cars in LFS behave as the different BMWs would.

I can't see what the models you've listed would contribute with.
