1990-1993 Cadillac Allante: Year-to-Year Changes

1991 Cadillac Allante: The standard Delco-Bose Gold Series sound system earned an upgrade to 200-watt output this year. Under the hood, Cadillac switched to platinum-tipped spark plug for long life. A new second-generation speed-dependent damping system was supposed to provide shorter reaction times to adjust suspension firmness, based on vehicle speed.

1992 Cadillac Allante: Virtually no change was evident in the 1992 Allantes.

1993 Cadillac Allante: Major changes went beneath the hood of the 1993 model, which went on sale in January 1992. Cadillac installed its 4.6-liter Northstar V8 engine, which also went into the '93 Eldorado and Seville. The new dual-overhead-cam V8 made 95 more horsepower than its overhead-valve predecessor and drove a new electronically controlled 4-speed automatic transmission. A new traction control system could simultaneously apply the brakes or shut down engine cylinders, to minimize front-tire spin. It worked at any speed. Previous traction control had acted upon braking only, and was inactive above about 30 mph. A new Road Sensing Suspension had sensors at each wheel, to "read" the road by measuring wheel position and body motion, automatically adjusting suspension damping. The system reacted in fractions of a second and replaced a simpler Speed Dependent Damping system that switched among three firmness settings according to vehicle speed. The rear suspension was redesigned and new all-season tires were rated to 155 mph. Also new were one-piece door glass, redesigned seats, an eight-speaker audio system, and a new console module with a dual fold-out cupholder. Despite the many improvements, Cadillac's 2-seater faded away after the '93 model year.
