It considers pretty much none of that (apart from 4wd). I am far too stupid to build a simulator that sophisticated. Far, far, far too mathematically incapable.
But what it DOES consider are acceleration numbers we have in fl database. And I know you have provided a lot of those. In fact, cars without sufficient amount of known acceleration figures won't even appear in the acceleration calculator applet.
It will be a very minimalistic, simple interface that allows you to select virtually unlimited set of cars from fl database and calculate acceleration times from x to y km/h (or mph, it will support both metric and imperial measurements) as well as completion times for x meters long race. (up to 400 m or 1/4 mile).
It will be extremely simple and easy to use. Forget about multitudes of input boxes usually associated with 1/4 simulators. Mine is more like a simple calculator. It is not a simulator, technically.
