Production by 1916 was over 700,000 model T's -- twice the output of all competitors combined. Production by 1916 was over 700,000 model T's -- twice the output of all competitors combined. The increased efficiency allowed Ford to cut prices by a third, selling the car for $850 in 1909, and $290 by 1924.
