New Tyre Physics



We are pleased to announce that a new tyre physics model is currently in the testing and refinement stage.

Many community members have been wondering what happened to the release of the new VW Scirocco and why there was no news about it.
Here are the reasons why :

While we were working on the Scirocco in December, we found that we could not make the LFS model handle as well as the real car. One of the reasons for this was that the LFS tyres had too much grip and this was causing the inside wheels to lose too much load while cornering. But simply reducing the grip would not have been a good approach... the result would have been just the same old LFS but at lower speeds.

We decided to look into a completely new core tyre model.

For several weeks it was just research and mathematics on paper, then the implementation started. A lot of old programming needed to be removed and refined in order to allow the new model to slot into its place. Next was the early refinement stage, at first seen only by the developers, while the main issues were sorted out. During this period we did not want to make any announcements about what we were working on, because it was possible that the new tyre model would not really work out. That did seem less likely as time went on, as more of the problems with the old tyre model came to the surface. The new LFS tyre model has a good mathematical basis for the way forces are produced from the physical state of the tyre, resulting in improved handling and feel with greater realism.

After some time we got to a stage where we felt the model was a clear improvement on the old physics. We updated all the default setups to use realistic values that would be found on similar real world cars and finally released it to our beta testers. Their verdict is unanimous : the new tyre physics model makes the cars much better and more realistic to drive.

There is quite a bit of refinement to be done and other aspects of car physics to update. Also the traction control and stability control of the VW Scirocco still need to be updated. So we cannot yet give a release date. This news item is intended as a progress report and to assure you that Live for Speed will be better when you do get the update!

A reminder :
- The new physics will be a free update for all LFS users
- The VW Scirocco will be available to S1 and S2 license holders
