Pierce-Arrow Model 66 History
History
The Model 66 debuted for 1910 as the flagship of Pierce-Arrow's new six-cylinder range, named for the rated horsepower of its enormous T-head inline-six. It is regarded as one of the greatest American cars of the brass and nickel era — a vast, stately machine for the very wealthy.
The engine grew over the model's life: roughly 714 cubic inches at launch, it expanded to around 825 cubic inches by 1913, making it for a time the largest-displacement engine offered in any production passenger car. About 1,250 Model 66s were built across the 1910–1918 run, and only a handful survive today, making it one of the most coveted of all pre-war American automobiles.
