Little is changed on Cadillac's STS sedan for 2007. Engines include a 3.6-liter V-6 or 4.4-liter Northstar V-8, both shared with a wide range of Cadillac vehicles. The latter engine receives a new six-speed automatic transmission for 2007, replacing last year's five-speed automatic.
All-wheel drive is available with either engine.
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.
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 joined the lineup in 2006. It packs a supercharged 4.4-liter V-8 with 469 horsepower.

Designed with a chiseled look, the four-door STS features what Cadillac says is a "faster profile" with "more rake" than the CTS. Cadillac styling touches include a wide airfoil grille with dual horizontal slats, a dihedral-shaped hood and vertically stacked twin-projector headlights. The sides of the STS are devoid of decoration. LED taillamps contain indirect optics to provide a more even lighting pattern.
Body-panel gaps promise close tolerances. Either 17- or 18-inch wheels can be installed.
Five occupants get to enjoy soft all-leather seats. Offerings include heated and ventilated seating and a heated steering wheel. The STS features genuine eucalyptus wood and aluminum trim.
Eight-way power front seats include four-way power lumbar adjustment, and a memory feature is optional. Trunk space totals 13.8 cubic feet.
Options include Bose 5.1 Studio Surround Sound and a DVD/CD changer that can play DVD audio discs as well as MP3 CDs. A DVD-based navigation system is available. General Motors' OnStar communication system includes automatic crash notification.
Under the Hood
The 3.6-liter V-6 produces 254 hp and 252 pounds-feet of torque; it teams with a five-speed automatic transmission. Cadillac's 4.6-liter Northstar V-8 generates 320 hp and 315 pounds-feet of torque. It runs through a six-speed automatic. Both transmissions include a manual-shift feature.
Six airbags, including front-seat side-impact and side curtain airbags, are standard. All-disc antilock brakes include brake assist. GM's StabiliTrak electronic stability system is also standard.
Cadillac's Seville was known for years as a potent road car. The STS builds solidly upon that reputation, adding a stylish exterior and ample technology.
Smooth-riding and well-controlled on good pavement, the STS isn't especially troublesome on rougher patches, either. The sedan steers with a light feel, comports itself neatly on wet pavement and yields confident sensations.
A performance-oriented V edition of the STS went on sale as a 2006 model. Equipped with a supercharged 4.4-liter V-8 that produces 469 hp at 6,400 rpm and 439 pounds-feet of torque at 3,800 rpm, the STS-V can accelerate from zero to 60 mph in less than 5 seconds. The supercharged Northstar engine teams with a new six-speed automatic transmission. Cadillac says that during shifts, power is instantly lowered and then carefully ramped back up, making gear changes virtually unnoticed.
Special STS-V design touches include a larger, polished stainless-steel wire-mesh grille; a lower front fascia that contains a bigger grille; brake-cooling ducts; and a splitter to counteract lift. Rocker panels are lower than usual, and the special sculpted hood allows space for the engine's supercharger. The STS-V features 10-spoke, painted, aluminum-alloy wheels. Features inside include hand-wrapped leather surfaces, Olive Ash Burl wood appointments and suede fabric seat inserts. Back to top
