Final answer:
Ford is the automobile manufacturer known for pioneering mass production methods through the use of assembly lines, making cars affordable and revolutionizing the industry.
Step-by-step explanation:
The automobile manufacturer known for using mass production methods is Ford. The mass production technique of using an assembly line was perfected by Henry Ford, which revolutionized the car manufacturing process. Ford's introduction of the moving assembly line in 1913 at his Highland Park plant allowed for more efficient production, leading to the Model T being produced in record time. This method significantly lowered the cost of production and the price of the vehicle, making automobiles affordable to the broader American public. As a result, this attracted a huge workforce to Detroit for these new assembly line jobs, fundamentally reshaping the automobile industry and the American workforce.
