A replacement for Seville was on Cadillac's to-do list for 2005, and it emerged as the STS. As expected, it was basically a stretched CTS, though with slightly softer body lines. Though 4.7 inches shorter overall than the Seville, the STS stood an inch taller on a 4.2-inch-longer wheelbase, to the benefit of interior room. Engine choices comprised a base 255-bhp 3.6-liter V-6, borrowed from the CTS, or the new "Gen II" Northstar tuned for 320 bhp. Both engines teamed with a five-speed automatic transmission. But in a rather large surprise, all-wheel drive was a $1900 option for the V-8 model; the V-6 got it as a 2006 addition.
The rear-drive STS was initially priced from $40,300 with V-6, $46,800 with V-8. Each was a pleasant, capable road car, and arguably more rewarding than the front-drive compromised Seville. Sportier types could shell out a hefty $11,000-$13,000 for a Preferred Equipment Group comprising Z-rated performance tires on 18-inch wheels (replacing standard 17s), Magnetic Ride Control, and uprated brakes and steering.
Even with that, however, the STS lacked the outright dynamic ability of most import-brand rivals, finishing seventh in an eight-way Car and Driver test. "The STS is agonizingly close to meeting the challenge of the best [midsize sport sedans]," said the editors, "but we think the sensibilities of its makers could use a little fine-tuning." Consumer Guide, by contrast, thought roadability just fine, but chided "subpar rear-seat space and cargo room. Interior materials and assembly are not up to the best in class, either."
An expected STS-V muscled in for 2006 at a stiff $74,270, but was fully loaded (no options) -- and loaded for bear. Enhancements were much like those of the V-Series XLR, but here the supercharged Northstar made a thumping 469 bhp and 439 lb-ft of torque, delivered to the rear wheels only via a six-speed automatic.
A three-way Car and Driver test ranked the mightiest STS between the BMW M5 and Mercedes' CLS 55 AMG, reflecting the Caddy's somewhat "softer" responses and plusher, less driver-oriented character. But as the editors observed: "...the STS-V's price nets you a no-apologies supersedan with big money left over -- almost 16 large versus the CLS 55. That's a huge advantage -- especially since the STS-V has this group's most comprehensive allocation of features and amenities..."
As if to hedge its bets with the STS, Cadillac freshened the front-drive DeVille for 2006 and changed the name to DTS. Optional Night Vision was canned -- demand for it had never been strong -- but the Gen II Northstar was specified, the G-body structure strengthened, and the chassis revised to improve both handling and refinement. Appearance was modernized too, with an edgy Art & Science-style lower-body reskin and improved dashboard ergonomics.
Like other GM divisions, Cadillac now stressed dollar value. Luxury I, Luxury II, and Luxury III versions delivered 275 bhp in the $42,000-$48,000 range; a sportier $47,000 Performance model packed 291 horses and many DeVille DTS features. Consumer Guide put the new line in perspective by noting that "Cadillac leaves any sporting pretensions to its [STS models. DTS] aims for the traditional American luxury-car buyer and scores. It's powerful, roomy, and refined, and matches most rivals for standard safety features."
