CarTest is a physics based simulator, certainly many effects are missing from the enormous range of subtleties in any real world car, however, the dominant effects that allow accurate absolute predictions and even better relative predictions of all common vehicle performance metrics are all present. That includes but is not limited to power, torque (full rpm dependent curves for both), weight, weight distribution, weight transfer, gearing, parasitic losses (drive train, tires and others), traction, friction and wheel spin, tire size, wheel growth with speed, environmental effects such as pressure and air density, road slope, shift times and last but not least aerodynamics including drag coefficient and frontal area.

Now that being said, I think you misunderstood what I mean by "eliminating variables". What that means is that if you compare car A and car B you can change one and only one parameter between the cars and ALL other inputs (variables if you like) are held completely fixed and identical. It is this sort of control and parameter isolation that is not at all possible in real world test, no matter how much care is taken.
