A new six-speed automatic transmission and the option of all-wheel drive are among the enhancements offered on the latest models of the Cadillac STS , the flagship sedan of the Cadillac portfolio. The STS is the product of unwavering attention to detail, resulting in refined performance, sophisticated luxury, overall harmony and purposeful innovation.
There’s no mistaking the STS as anything but a Cadillac. Styling cues include vertically stacked headlamps and light-emitting diode (LED) taillamps, LED center high-mounted stop light (CHMSL) and horizontal “spline lines.” These are further enhanced on the latest models by larger, standard 18-inch polished aluminum wheels on V-6 Sport Luxury models and by stylish wheel center caps featuring the Cadillac wreath and crest emblem
With an overall length of 4985 mm, a wheelbase of 2957 mm and front/rear track of 1596/1581 mm, the STS is the largest sedan in the Cadillac portfolio. The STS ensures a particularly spacious and stylish interior, with an emphasis on high-quality fit and finish.
Quality materials are used throughout. The interior choices include aluminum trim on both console and instrument panel on the Elegance and two color choices for wood trim that is standard on the Sport Luxury. Dual-firmness leather seats are specially tanned for a softer feel, with the added option of Tuscany leather upholstery. Natural grained surfaces on the door and instrument panel ensure an inviting, tactile touch, as do the headliner and interior pillars, which are soft backed and covered with a Monaco woven fabric.
The STS is offered with the 189 kW (257 hp) 3.6L V-6 VVT or the 239 kW (325 hp) Northstar 4.6L V-8 VVT. Both engines incorporate variable valve timing (VVT) and are mated to Cadillac’s automatic transmissions with Driver Shift Control, driving the rear wheels. V-8 models will feature a new six-speed automatic transmission along with the option of all-wheel drive (available at the beginning of November 2006).
Four-cam variable valve timing gives the V-6 engine increased efficiency, with benefits in fuel economy, emissions and flexibility. Ninety percent of the 3.6L V-6’s peak torque is available from 1600 rpm to 5800 rpm. In addition, an electronically controlled throttle (ETC) coordinates the driver’s intentions with the actions of the various control components. With the V-6 the STS achieves 0-100 km/h in 7.4 seconds. The 4.6L Northstar engine delivers 0-100 km/h acceleration in 6.2 seconds.
Integrated chassis control technologies combine performance with a comfortable ride, including two-mode Magnetic Ride Control with performance or touring selections as standard on the V-8. Driver involvement is further enhanced by ZF steering gear and four-channel StabiliTrak. This stability system assists the vehicle in maintaining the driver’s intended path by applying a brake force at any corner of the vehicle independent of the driver’s use of the brake pedal. StabiliTrak is fully integrated with the traction control and ABS systems.
Technical appointments include a keyless access system with a push-button start; optional Adaptive Cruise Control (ACC) and reconfigurable four-color head-up display (HUD); heated and ventilated seats and heated steering wheel.
An enhanced equipment package for the latest STS V-8 Elegance models includes heated seats and power lumbar support as standard, along with eight-way power seat adjustments for the driver and front occupant. This incorporates a memory package with presets for two drivers and automatically adjusts the outside rearview mirrors; power tilt and telescoping steering wheel position, radio and climate control settings.
Additional refinements on the Sport Luxury model include the Eucalyptus wood trim package, heated front seats, heated steering wheel, power lumbar adjustment on the front seats and an uplevel infotainment system, with a 15-speaker Bose 5.1 Surround Sound system with an integrated six-disc CD/DVD changer, an eight-inch (203 mm) VGA quality touch screen, Bluetooth capability, voice recognition and a navigation system.
