While there have been inevitable compromises and simplifications made in the application of the collected data in order to suit the physics engine and maximize the value of the driving experience, and acknowledging perfection is a complex goal to aim for even at this level of race car simulation, we hope the end result provides a level of accuracy all simracers can be satisfied with. The physics have evolved considerably since the Prologue release, with tyre physics in particular having been extensively revamped. They are based upon a large amount of real data which came not only from reputable books and studies, but also contemporary CART engineers and drivers. physics notesThe physics in the full release of CART Factor are a result of intensive research in all areas of vehicle dynamics and meticulous crafting of the rFactor physics engine spanning 30 months of development. Full, optimised DX7, DX8 and DX9 support.Accurate aero distribution, downforce and drag values, utilising CFD and wind tunnel verified data.


Reynard 98I, Swift 009c, Penske PC27 and Lola T98/00 chassis.Two tyre brands with unique characteristics.

29 cars from the 18 teams of the 1998 CART season.
