Cadillacswere restyled and re-engineered for 1961. The new grille slanted back towards both the bumper and the hood lip along the horizontal plane and sat between quad headlamps. New forward slanting front roof pillars with non-wraparound windshield glass was seen. The revised backlight (rear window) treatment had crisp, angular lines with thin pillars on some models and heavier, semi-blind-quarter roof posts on others. A new short-deck sedan was situated in the 6300 lineup, ostensibly created for rich dowagers with small parking stalls in their luxury apartment houses.
The DeVille models were retained as the 63 sub-series (which was technically part of the Sixty-Two line), but the Eldorado Seville and Brougham were dropped. This moved the Eldorado Biarritz convertible into the DeVille sub-series.
DeVille models featured front fender series designation scripts and a lower body “skeg” trimmed with a thin three-quarter length spear molding running from behind the front wheel opening to the rear of the car. Standard equipment was the same used on 6200 models plus Two-way power seat and power windows. The Biarritz convertible also had power vent windows, whitewall tires, Six-Way power bench seat (or bucket seats) and remote control trunk lock. The new short-deck four-door hardtop appeared in mid-season and is often referred to as the Town Sedan.
