Cadillac Eldorado sixth generation 1965-1966
For 1965 the Eldorado became a Fleetwood sub-series although there was strictly speaking no separate Fleetwood series at this time. It was consequently marketed as the Cadillac Fleetwood Eldorado, in a similar fashion to the Cadillac Fleetwood Series 75 and the Cadillac Fleetwood Sixty Special. The Biarritz nomenclature was finally dropped from sales literature, probably because there was no need to distinguish the convertible from the long absent Seville and Brougham. The Eldorado was redesigned but rode on the same 129.5-inch (3,290 mm) wheelbase. The elevated tailfins were removed, with fins planed flat, and sharp, distinct body lines replaced the rounded look. Also new were a straight rear bumper and vertical lamp clusters. The headlight pairs switched from horizontal to vertical, thus permitting a wider grille. Curved frameless side windows appeared with a tempered glass backlight. New standard features included lamps for luggage and glove compartments and front and rear safety belts. Power was still supplied by the 340 horsepower 429 cu in (7,030 cc) V8. Perimeter frame construction allowed repositioning the engine six inches forward in the frame, thus lowering the transmission hump and increasing interior room.
In 1966 changes included a somewhat coarser mesh for the radiator grille insert, which was now divided by a thick, bright metal horizontal center bar housing rectangular parking lamps at the outer ends. Separate rectangular side marker lamps replaced the integral grille extension designs. There was generally less chrome on all Cadillac models this year. Cadillac crests and V-shaped moldings, front and rear, were identifiers. Cadillac "firsts" this season included variable ratio steering and optional front seats with carbon cloth heating pads built into the cushions and seatbacks. Comfort and convenience innovations were headrests, reclining seats and an AM/FM stereo system. Automatic level control was available. Engineering improvements made to the perimeter frame increased ride and handling ease. Newly designed piston and oil rings and a new engine mounting system and patented quiet exhaust were used.
