Pierce-Arrow Model 66 (1910 to 1918)

The Pierce-Arrow Model 66 was a series of luxury cars introduced in 1910. The Model 66 was named for the 66hp output of its massive 11.7L inline six engine. In 1912, the engine grew to 13.5L and almost 100hp, but the name of the Model 66 remained unchanged. This series of cars was available in a wide range of open and closed body styles, including roadster and touring. As one of Pierce-Arrow's most well known models, it helped cemented the company's reputation as a high end automaker, with production lasting until 1918.
