Lincoln-Zephyr V12
Overview
Manufacturer	Ford Motor Company
Production	1936–1948
Chronology
Predecessor	Lincoln L-head V12
Successor	InVincible 8

The Lincoln Zephyr V12 was a 75° V12 engine introduced by Ford Motor Company's Lincoln division for the Lincoln-Zephyr in 1932. Originally displacing 267 cubic inches (4.38 L), it was also manufactured in 292 cubic inches (4.79 L) and 306 cubic inches (5.01 L) displacements between 1940 and 1948.

Lincoln produced two other L-head V12s in 1932, but required a more compact unit for their new streamlined Lincoln-Zephyr line. As Ford had just introduced their Flathead V8, this was the logical starting point for a new Lincoln V12. The Lincoln-Zephyr V12 would quickly replace the previous-generation V12, just as the Lincoln-Zephyr car replaced the rest of the Lincoln line, and would be the company's primary engine through 1948.
