Pierce-Arrow was always one of the most opulent and expensive luxury cars built in America, but with the introduction of the 66-horsepower model, it moved into a class that was nearly unmatched. The 66 featured an 825 cubic-inch, six-cylinder engine, the largest engine ever installed in a production car - a record shared with Peerless Automobiles that still stands today as noted in the Guinness Book of World Records. Along with the enormous engine, every part of the driveline of a 66 is of larger scale than the other models, giving a true example of how Pierce-Arrow set out to build the best automobile of the era.

This 66 7-passenger touring is a quintessential example of not only Pierce-Arrow's grandest model, but also their most popular open car body, the ubiquitous 7-passenger touring.
