In the second half of 2004, GM will replace its Cadillac Seville with an all-new model, expected to be called the "STS," which is shown here as a first prototype in the vicinity of GM's Detroit headquarters.
The STS will be based on GM's Epsilon platform, and sports a Northstar V-8 engine and rear-wheel drive. It will have a significantly bigger cabin than the smaller CTS.
The STS will also feature Cadillac's bold new styling scheme with sharp angular looks, vertically stacked headlights and thin rear lights, as introduced with the CTS, the XLR roadster, and the latest generation Escalade luxury SUV.
A special high-performance "STS V-Series" edition is expected to be introduced in 2005, and will feature a specially modified Northstar engine tuned to 400 hp.
