The Cadillac deVille (series 6C) had a new V-8 which was nearly 20
percent more powerful and 10 percent larger than the unit it replaced. Yet
its fuel economy was virtually unchanged from the 1987 level. The larger
V-8 also now had roller lifters and low friction pistons. The de Ville had a
revised suspension and engine mount rates as well as revised heater/air
conditioner components and electronic cruise control system. Previous
options now standard for the de Ville included
the tilt and telescope steering wheel
cruise control
dual comfort front seat
controlled cycle wiper system
power trunk release
heavy-duty battery.
The deVille's THM 440 automatic transmission now had a computer-controlled
electronic torque management to prevent overstressing of driveline components.
Six new exterior colors were introduced for the de Ville. A 4.5 liter V-8
engine identification plaque was added to the decklid. The armrest
switch-plate was changed from cherrywood to black for 1988.
Among the numerous electronic changes for 1988 found in the de Ville were
a higher resolution internal speed sensor and a new under-dash relay center.
FLEETWOOD SIXTY SPECIAL
The Fleetwood Sixty Special (also series 6C) continued to offer a longer
wheelbase than the D'Elegance model with which it shared the same
refinements and features for 1988.
