1913 Pierce-Arrow Model 66
- Engine
- 13.5L T-head inline-six, ~100 bhp

The 1913 Pierce-Arrow Model 66 (chassis 66667) is one of only 14 known surviving examples of what was, at the time, the world's largest-engined production automobile. Delivered originally in Chicago, it later served the Minneapolis Fire Department before passing through a radio station and the Sioux City Shriners. Restored by enthusiast Irving Jensen with period-correct cast aluminium coachwork, it has appeared at Pebble Beach and logged over a dozen long-distance tours, earning a reputation as a genuinely roadworthy rather than purely cosmetic survivor.
