The Eldorado continued to be available as the Eldorado coupe and as the Eldorado Biarritz, which was ordered as Option Code YP3. A new white diamond color was introduced, allowing a choice of 18 colors for the Eldorado buyer. The black metallic roof of 1988 was replaced with a sable black version. The Biarritz roof was revised via the elimination of the bright bead adjacent to the roof molding. New options consisted of the electrochromic mirror, Delco/Bose Symphony sound System and digital disc player. New standard features consisted of an accent molding, remote fuel door release, front license plate mounting, the AM/FM stereo radio used on the Sixty Special and aluminum alloy wheels with a snowflake finish.
The 1989 Eldo boasted more standard equipment with no significant price increase, while the ’90 gained 35 bhp with no loss in mileage by switching from throttle-body injection to the more efficient multi-port type. A driver’s airbag became standard that year, and the Touring Coupe returned as a nine-second 0-60 sprinter with 215/60 performance tires, 16 x 7-inch forged-alloy wheels, 10-way power sport seats, and a deftly dechromed exterior. Performance improved further for 1991 via a newly stroked 4.9 V-8 delivering 200 bhp and 0-60 in 8.2 seconds. Even better, ABS became standard, as did a velvety-shifting new chip-controlled automatic transaxle. Also standard now was Computer Command Ride, the speed-dependent variable-rate damping system pioneered for 1989 on Cadillac’s singular two-seat Allanté.
Interior changes for 1989 were headlined by a high-gloss bird’s-eye maple wood trim for the instrument panel, front console and door panels that were installed on the Eldorado Biarritz and standard on Eldorados with the B20 Appliques option. The Eldorado’s floor mats were of the new design used on other 1989 Cadillacs. A passive vehicle anti-theft system (VATS) that disengaged the starter, fuel pump and ECM we standard. Also found on all Eldorados was a driver side express-down window with a three-second activation and a tap up/down deactivation. The heater/defroster and bi-level air modes were revised to provide a more gradual and comfortable transition from warm to cool air, as well as an increased bi-level airflow.
