Most likely outsorcing has nothing to do with it, but rather it's a matter of budget and how much content you have to do.
Even if both games had the same budgets (and they do not) Forza would have less allocated to each car because it has so much more cars to model.
What you just said does mean that outsourcing has a lot to do with it.
Not to mention the amount of data Polyphony artists can work with, considering how they work closely with car companies.
