Lincoln-Zephyr V12 engine

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 (4.4 L), it was also manufactured in 292-cubic-inch (4.8 L) and 306-cubic-inch (5.0 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.
