History
Franklin Series 11-A
The Franklin Series 11-A represented the pinnacle of air-cooled automotive engineering in the late 1920s. Unlike virtually all competitors, Franklin eschewed water cooling in favor of direct air cooling with distinctive finned cylinders. The aluminum construction kept weight down while the overhead valve inline-six provided smooth, reliable power. Franklin's unconventional approach earned a devoted following among engineers and aviation enthusiasts who appreciated the elimination of radiator freezing and boiling issues.
