 Following the discontinuation of the Model K after 1940, Lincoln shifted its production exclusively to the Lincoln-Zephyr design; after World War II, the Zephyr name was dropped, lasting through 1948.The Lincoln-Zephyr would serve as the basis of the first Lincoln Continental, the longest-running nameplate of the Lincoln brand.The model line was powered by a V12 engine, in contrast to the V8 and inline-8 engines of its competitors.
