Vehicle Overview

Cadillac stepped into rear-wheel-drive territory with its STS sedan, which replaced the front-wheel-drive Seville for 2005. Built on a Sigma-based architecture, like the company's smaller CTS sedan and SRX sport utility vehicle, the STS was Cadillac's first rear-drive luxury performance sedan in a quarter of a century.

For 2006, STS models with V-6 or Northstar V-8 power can have all-wheel drive instead of rear-wheel drive. Cadillac says an STS equipped with the V-8 and rear-wheel drive can accelerate from zero to 60 mph in 6 seconds or less.

Technology, whether standard or optional, is a big part of the STS picture. A Performance Algorithm Liftfoot system controls transmission operation to enhance spirited driving. Two-mode Magnetic Ride Control is optional. Keyless Access lets you enter and start the vehicle by carrying a special key fob. 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 gets a four-color head-up display.

A high-performance STS-V sedan joins the 2006 lineup. It packs a supercharged 4.4-liter V-8 that generates 469 horsepower.
