Introduction
The all-new 2005 STS marks Cadillac’s return to the luxury performance segment, replacing the Seville in the Cadillac lineup. The STS is based on the Sigma architecture, which is also the platform for the CTS and CTS-V sedans, and the SRX crossover SUV. The STS styling bears a strong resemblance to the CTS but has a softer, smoother edge to the sharp lines and its own distinct look. The STS name was previously used for the high-performance trim of the Seville. The Seville name was first used on coupe versions of the Eldorado in 1956, and the Seville model debuted in 1976 to compete with European luxury brands. The Seville name was retired with the end of 2004. Seville SLS production ends in December 2003.
