Production1903–1904
Recorded originUnited States
ClassOpen runabout
Power6.5 hp
More powerful two-cylinder Caloric runabout on the same documented 66-inch/1,680 mm wheelbase as the 4½ HP. The engine's blowtorch-preheated cylinder-head starting procedure is documented, but surviving summaries do not establish whether the two runabouts differed beyond output.
