With LaSalle gone for 1941, Cadillac became a one-make, one-engine division of General Motors. For the first time since 1926, all Cadillac products used the same engine, a 346-cid L-head V-8 producing 150-hp. The Oldsmobile Hydra-Matic automatic transmission was offered as an option, as was air conditioning for the first time. New front-end styling introduced Cadillac’s trademark rectangular eggcrate grille while fenders incorporated headlights keeping with the styling trends of the day. Sixty Specials featured front fenders that gracefully flowed into the front doors, a styling cue that would be widely-copied. 1941 marked the final year of the unique Sixty Special styling originating in the landmark Bill Mitchell design of 1938. The 1942 was a more mainstream, less distinctive car. Sixty Specials lacked running boards and the triple chrome strips found on the fenders of other Cadillac models, further differentiating the model from its lesser siblings. It is one of just 220 Imperial Sedans with formal glass division produced for 1941.
