The Allanté was refined for 1989 by virtue of
a larger 4.5 liter port fuel injection engine that provided increased power
and improved
performance. With 10 percent greater displacement, new low-restriction
exhaust manifolds
and improved flow air cleaner, the Allanté's engine had a 17 percent
increase in
horsepower and a 13 percent increase in torque. Its 0-60 mph time was
improved from 9.5 to
8.3 seconds. Performance from 40 to 80 mph progressed from 12.3 to 10.3
sec. The
Allanté's top speed increased from 125 to 135 mph.
Exterior changes for 1989 began with a new light blue metallic color
choice. Seven colors
were available as gold metallic was deleted. Central door unlocking was
now available from
the trunk. Several improvements took place in the Allanté's soft top.
The lower well
and relocated roller guides prevented fabric wear, a self-folding fabric
eliminated the need for
tucking and walking around the vehicle, the use of dual springs reduced
lifting effort and a
major reduction in body squeaks and rattles was achieved.
A total of three interior colors, including a new charcoal color, compatible
with all exterior
colors were offered. Both driver and passenger express-down windows
were standard.
Cadillac's VATS was also standard. A new seat design was used with a
softer foam on
cushion and back wings, along with softer wrinkled leather trim and French
seams for the
wings and head restraints. A softer trim was also used for the instrument
panel, doors,
armrests and upper door trim. An engine oil life indicator was now
standard. The 1989
Allanté also had reversible and washable carpeted floor mats with
retention features.
Significant technical developments were also part of the 1989
Allanté package. A new
speed-dependent suspension provided for a variety of ride/handling
characteristics. At low
speed the emphasis was on a greater sense of isolation and smooth road
feel. At normal
cruising speeds the suspension provided what Cadillac regarded as
"traditional Allanté ride qualities." For higher speeds the focus was upon stability without a
significant loss of
ride quality. This system also monitored braking and acceleration to reduce
the rate of fore/aft
movement. A new variable-assist steering system reduced pump output
flow as engine speed
increased. It also reduced parking and low speed effort while increasing
steering effort and
precision at higher speeds. In order to improve ride softness and road
isolation the bushings
and cradle mounts were retuned. New 16 in. x 7 in. wheels and Goodyear
P225/55VR16 tires
were standard.
