Power windows, door locks and outside mirrors are also standard. A unique option is the OnStar system, which links a cellular phone to a satellite navigation system and can provide location assistance, track the car if it's been stolen, automatically summon help if the airbags deploy, and even unlock the doors, all via a satellite. By now most all automotive buffs know about Cadillac's Northstar system, a powertrain combination that centers around an all-aluminum 4.6 liter V8 engine with dual overhead camshafts and 32 valves. In standard Eldorado form, it produces 275 horsepower and 300 lb-ft of torque, more than enough to launch the car very quickly to speed. Passing power is impressive, too, even over high elevation mountain highways.
Fuel mileage is adequate, provided the driver can refrain from using a heavy right foot.
A set of platinum-tipped spark plugs, a distributorless ignition and an electronic fuel management system allows the car to be driven 100,000 miles between tuneups. Base Eldorado models use computer-controlled suspension, to automatically dampen road shocks instantaneously. The base model uses softer suspension settings than the Touring Coupe, giving an ultra- plush highway ride over almost any bump. New lower control arm bushings have been realigned to allow the main bushing to absorb more cornering loads, while a stiffening of the frame helped reduce vibration and harshness. Steering feel is enhanced for 1997 with the help of MagnaSteer, a combination of electronic and hydraulic systems which adapts to changes in vehicle speed and road conditions.
