It taking over 100 hours to the get the Factory Driver achievement was just PR talk by Turn 10. My guess it can be done in less then 50 hours with most manufactures. I have 930/1000 achievements in Forza 2, 985/1000 in Forza 3, 880/1250 in Forza 4, 1095/1500 (only 360 game where I have over 1000 points) in Forza Horizon and I'm 4th tier in the Forza Rewards program.
