Like ACC, Cadillac’s Intellibeam Headlamps detect other traffic and adjust accordingly. Also available on V8 models, these headlights switch between their high and low beams automatically. When headlights or taillights are perceived the units switch to the low-beam setting. With no oncoming or up-ahead traffic, they stay on high. Cadillac assures that the sensors filter out ambient lighting that would cause unnecessary dimming.
While the optional Intellibeam lamps are not crucial components, the technologically advanced safety features are. Eight airbags - two in front, two to the side of the front passengers, and a curtain at each outboard position - maintain occupant integrity in the event of a collision. Four-wheel disc brakes with ABS behind standard 17-in. wheels provide binding power with the Standard or Luxury package checked. Sport treatment yields larger discs surrounded by 18-in. wheels. Rack-and-pinion steering with variable assist is also considered a “Sport” option. Other options include heated and ventilated seats, a heated steering wheel, Tuscany leather, XM satellite radio, a sunroof, and exotic eucalyptus wood trim.
The STS could prove a formidable opponent to other mid-size luxury sedans. Five-series and 7-Bimmers, E-class Benzes, and GS/LS430 Lexuses take note - the General now has a contender.
