By 1911, Ford was building all Model T's at the Highland Park plant in Detroit, Michigan. Many of these cars, however, were shipped in knocked down form to assembly plants all over America and in several foreign countries.

Ford continued to improve the quality and dependability of the Model T and in 1911 changed to a stronger rear end assembly and used tapered axles to secure the wheels. The engine now had enclosed valves and an access pan to adjust the connecting rod bearings. The standard factory color was dark blue and all Model Ts were now supplied with tops, windshields, and headlamps as standard equipment. Ford believed there was nothing else needed on his cars and early sales agreements stated that 'the warrantee would be voided if any accessories were added.'

Approximately 40,000 Model T Fords were built and assembled during the 1911 model year. This was more than double than were produced in 1910. The bulk of the Model T's produced were touring cars which contributed to over 60 percent of all models sold.
