In 1959, the memorable "zap!" fins appeared on nearly all Cadillacs this year, including the Sixty Special. Now riding a 3 in (76 mm)-shorter wheelbase (130 in (3,300 mm)), the 225 in (5,700 mm)-long Sixty Special continued as a pillarless hardtop with its own distinct moldings - including a side-mounted dummy air-scoop on the rear fender, and a thin chrome bead that ran from the front fender back to the rear bumper, and then forward again to the front wheel well. The fin-mounted tail lights pods (which were body-colored on lesser Cadillacs) were chromed. The 390 cu in (6.4 L) engine provided 325 horsepower (242 kW). Air suspension, utilizing freon-filled shock absorbers, was optional on Sixty Special. Cadillac also advertised a new "Scientifically engineered" drainage system. Although the Sixty Special script was gone, the Fleetwood script remained, and since the only other Cadillac bodied by Fleetwood was the Series 75, for this and many other reasons, there was no confusing the Sixty Special with other Cadillacs. However a front fender-mounted cloisonne "Sixty Special" emblem would appear the following year and last through 1962.
1960 saw new (shorter) rear fins, and a cleaner side-trim design,as well as a rear "grille" design shared with Eldorado. The Sixty Special was also distinguished by a new front fender-mounted cloisonne "Sixty Special" emblem. Wheelbase remained 130 in (3,300 mm), and the $6,233 price was the same as the 1959. New for 1960 was a standard vinyl roof covering, and the small chrome "louvers" returned (first seen in 1942, last seen in 1956) mounted on the rear fenders, just ahead of the tail lights. Power steering and brakes were standard.
