The 1938-1940 Cadillac Series 90 Sixteen and overall Sixteen production was never more than a few hundred per year after 1933. Both the V-12 and original V-16 engines were dropped after 1937, but Cadillac offered a new L-head V-16 for three more model years.

At 431 cid and 185 bhp, the 1938-1940 Cadillac Series 90 Sixteen powerplant was smaller and lighter, but more powerful than the earlier jewel-like engine. However, it's never received collector acclaim. The advent of precision-insert con rod bearings helped eliminate the traditional knock and engine wear of eights and sixes, which had occasioned multi-cylinder engines.

Cadillac found it uneconomical to continue this Sixteen past 1940, even though it shared its wheelbase and many body styles with the Series Seventy-Five. Few open models were built, most being Imperial and formal sedans.
