Fresh off its award-winning accomplishment of interchangeability of parts in 1908 with a one-cylinder model, Cadillac introduced a new model, the Thirty, in 1909.
This new four-cylinder model advertised that “1/1000th of an inch is the standard of measurement.” This was in reference to Cadillac’s use of Johansen gauge blocks, precision gauges used in machine setup that allowed very low tolerance of deviation in parts.

This Model Thirty represents a new body style introduced in 1911, the Fore-Door. Careful inspection will reveal that the car has only three doors. The name refers to the fact that previous Cadillac Touring cars featured only rear doors. In 1911 a stripped down Model Thirty covered 1,448 miles in 24 hours at an average speed of 60.03 miles per hour to set a new record. In 1912, Cadillac would become “The car that has no crank,” with the introduction of the electric starter motor.
