Introduced in 1908, the Model T offered simplicity, reliability, and respectable performance in an affordable package. When Henry Ford added the moving assembly line to Model T production, the result was a car that not only became cheaper to buy every year but one that dominated world-wide automobile production for almost two decades. By 1922, over one million "Flivvers" were being sold annually. Its aging design led to the replacement of the Model T with the Model A for the 1928 model year. The Model T had a front mounted 177 cubic inch inline four-cylinder engine producing 20 hp for a top speed of 40-45 mph. The cost of a 1915 Model T was approximately $390 dollars. Henry Ford’s approach to the Model T design was one of getting it right and never changing.  He believed the Model T was all the car a person would ever need.  However, there were design changes. For example, in 1915 the hood design retained the five-sided design but louvers were added to the vertical sides, and electric headlights replaced carbide headlights.
