For the 1948 model, Cadillac
introduced the
e
which set the trend in automotive styling for nearly two decades. This
was followed
by the 1949 model with
the two door hardtop Coupe DeVille
and the modern overhead valve,
high compression V8 engine.
Engineering innovations, con-
veniences and styling dominated the
'50s and '60s. Cruise control, auto-
matic climate control,
tilt and
telescoping steering wheels, twilight
sentinel and four door hard tops all
debuted in these years. In 1957 the
Eldorado Brougham featured
ad-
vances such as air suspension, mem-
ory seat, automatic electric door
locks, transistor radio, a brushed stainless steel
roof and low profile
tires.
1953, was redesigned for 1967 as the
first front wheel drive personal lux-
ury car. The
472 cu. in. V8 engine
used
in all Cadillacs in 1968 and
1969 was enlarged to 500 cu. in. for
all 1970 Eldorados.
An Air Cushion Restraint Sys-
tem (airbag) was available for
1974,
1975 and 1976 Cadillacs.
Analog Electronic Fuel Injec-
tion was available, on
1975 Cadillacs
and was standard
on the new inter-
national size 1976 Seville. In
1978,
the Trip Computer option incor-
porated an on-board microprocessor.

A 1993 Cadillac Allantit in stock
technical configuration, was selected
as the pace car for the 76th Indianap-
olis
500. The demanding pace car
performance and handling require- ments were met because of such
advances as the Northstar system.
The system includes the
32 valve,
dual overhead camshaft, Northstar
4.6 liter V8 engine, 4T80 E electroni-
cally controlled automatic transaxle,
road sensing suspension,. speed sen-
sitive steering, antilock brakes and
traction control. For more than nine decades
Cadillac has been
a leader in quality
and technical innovation. Now more

Speed Sensitive Steering (SSS)
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort is also increased proportionately. At highway speeds the
amount
of steering effort is greatly increased to provide a manual like
steering feel for maximum control and enhanced vehicle stability.
Speed Sensitive Suspension
The Speed Sensitive Suspension automatically controls the ride of your
vehicle. The system controls damping forces in the shock absorbers and
struts in response to various speed and road conditions. There are three
dampening modes: Comfort, Normal and Firm. As the vehicle speed
increases, the firmness of the suspension increases. The system is in the
Comfort mode, for speeds less than
40 mph (65 km), normal mode for
speeds between 40 mph
(65 km) and’70 mph (110 km/h), and firm for
speeds greater than 70 mph
(1 10 km/h). The system also stiffens damping
during hard acceleration, braking and cornering for increased control.
The Speed Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from acceleration
and determines optimum mode strut valving
(or suspension stiffness) for
your current operating conditions. The computer also receives feedback

the vehicle must be towed on the front wheels, don't go more than 55
mph (88 km/h) or farther than 500 miles (804 km) or your transaxle will
be damaged. If these limits must be exceeded, then the front wheels have
to be supported on a dolly.
NOTICE:
Do not attach winch cables or "J" hooks to suspension
