In the late 1920s, most auto manufacturers had shifted production to multi-cylinder internal combustion engines. As such, Cadillac needed to keep up with the Joneses and began working on a V-12 and V-16 model. Even at that time, it didn’t take long, and by 1931 Cadillac began selling the Cadillac Series 370 V-12. Surprisingly, Cadillac offered the V-12 with the same bodywork as the V-16, despite the fact that it featured a shorter wheelbase. This left the V-12 model looking so similar to the V-16 model that the only easy way to tell a V-12 from a V-16 (unless they were parked next to each other) was to look for the V-12 Badge.
