Vehicle Overview

Cadillac takes another step into rear-wheel-drive territory with its new STS sedan, which replaces the front-wheel-drive Seville. Built on a Sigma-based architecture, like the automaker's smaller CTS sedan and SRX sport utility vehicle, the STS is the first rear-drive version of the luxury performance sedan in more than 25 years. All-wheel drive is also available, which is another Cadillac first. Cadillac initially used the Seville name in 1956, and the STS is the sixth generation of that vehicle.

Introducing the STS at the 2004 New York International Auto Show, Gary Cowger, president of General Motors North America, said the sedan will deliver "serious performance credentials." One of two engines can be installed: a 3.6-liter V-6 or a Northstar 4.6-liter V-8. STS models fitted with V-8 power can have either rear- or all-wheel drive. When equipped with the V-8 and rear-wheel drive, Cadillac says the STS can accelerate from zero to 60 mph in 6 seconds or less.

Technology, both standard and optional, is a big part of the STS picture. A Performance Algorithm Liftfoot system controls transmission operation in a way better suited to spirited driving. Two-mode Magnetic Ride Control, with performance and touring modes, is optional. With Keyless Access, keys become unnecessary to enter and start the vehicle as long as a special key fob is carried. Smart Remote Start operates from up to 200 feet away.

Optional Adaptive Cruise Control uses radar to maintain a set distance from vehicles ahead. Intellibeam automatically selects either the high- or low-beam headlights in response to oncoming lights. The driver also gets a four-color head-up display. A ZF performance steering gear is optional.

Considered Cadillac's global luxury performance sedan, the automaker describes the STS as a "distinctly American package." Scheduled to go on sale in the fourth quarter of 2004, it's the largest sedan in the Sigma family.
