Project CARS – Spectacular On Board Video

Francisco Rodriguez has created a stunning on board video with Project CARS + new tire model feature news.

Francisco Rodriguez has created a stunning on board video with Project CARS, showing a run with the Ruf RGT-8 at California Highway.

The video lets us check out Francisco pushing the car to the limit, including some mighty impressive pedal work and some great saves.

Even though the Seta tire model has been introduced to Project CARS a while ago, the physics development is nowhere near done as new features are being added to the complex tire model all the time.

The latest addition to the STM is comprehensive and highly dynamic heat modeling, as explained by Slightly Mad Studios’ physics guru Andrew Weber:

The gist of the model is that the road flashes temperature into the contact patch (flash heating). That heat diffuses into the bulk rubber of the tread. The tread heat transfers with the ambient air and the carcass. The carcass interacts with the internal air. The internal air interacts with the rim. The rim interacts with the well air (air ‘inside’ the rim well). The rim air interacts with both the ambient air and the brakes. There is also evaporation cooling in the wet.

Depending on the resolution of the contact patch and the tread, each of those has many “heat reservoirs”, one per seta in the patch and one per tread element in the whole tread. Right now most tires have 36 of each. Beyond that there is also one reservoir for each of: internal tire air, rim, well air, and carcass. FlexiCarcass may have more than one. ElementCarcass will have more than one. From the tire model point of view, the road temp, ambient temp, and brake temp are just numbers fed to the model each time step.

Bottom line, most current tires will have 76 reservoirs.

The new model is being introduced car by car as both WMD testers and professional race drivers Ben Collins & Nicolas Hamilton will help tweak & fine tune it for maximum realism.

Project CARS is coming to the PC, Xbox 360, Playstation 3 and Wii U in 2014. More info can be found on the WMD website.
