The Seville sedan and Seville Touring Sedan (STS) again represented the series, with refinements and upgrades aligned with those listed for the Eldorado and Eldo Touring Coupe, respectively.
Seville again used the 4.9-liter V-8 and 4T60-E transmission while the STS received the new Northstar 4.6-liter V-8 and 4T80-E transmission.
Final drive ratio for the Seville was 2.97:1 while the STS’s was 3.71:1.
In addition to the Northstar engine, STS featured the new Bosch ASRIIU traction control system. Designed to eliminate wheel spin on slippery road surfaces, the system reduced engine torque by shutting down up to five cylinders simultaneously while applying the brakes.
The STS was distinguished by its monochromatic paint scheme, STS badging and Northstar engine identification.
The STS also featured a body-color grille with wreath-and-crest emblem, specific rocker molding and bright dual exhaust outlets.
New standard features for STS included solar control glass and two new exterior colors: Academy Gray and Dark Cherry Red Metallic.
