Review of the 2007 Cadillac STS

  • Thanks to its handsome styling, strong performance, well-balanced chassis and luxurious cabin, the 2007 Cadillac STS is a strong player in an arena filled with talent. The Caddy's competitive pricing is another factor that makes it a must on any consumer's short list.

  • Safety
  • Pros

    Full-size luxury car at a midsize price, nimble road feel for this size of car, powerful engine options, available all-wheel drive, optional Bose stereo is one of the best in its class.

  • Cons

    Sporty bucket seats might be too firm for some, some plastic interior panels not quite up to German standards, only automatic transmissions available.

  • What's New for 2007

What's New for 2007

The 2007 Cadillac STS sees a couple of hardware changes. A six-speed automatic transmission debuts on V8 versions, and the Performance Handling Package adopts Brembo brakes, Michelin Pilot Sport tires and 18-inch chrome wheels. In addition, the wheels now feature a colored wreath and crest, and the powertrain warranty is extended to five years/100,000 miles.


Debuting a few years ago as the successor to the Seville, the STS (Seville Touring Sedan) made it clear that Cadillac was serious about going tire to tire with Europe's iconic luxury sport sedans. The 2007 Cadillac STS has the looks, power, performance and luxury trappings to make it an enticing package.

The STS wears the company's new design language well, tastefully incorporating the trademark egg-crate grille, stacked headlights and sharply creased body panels. The STS' platform is based on that which underpins the CTS and SRX models, meaning a fair amount of athletic DNA is in this larger sedan. Plenty of handsomely stitched leather and fillets of wood trim fill the cabin, and the latest technologies, such as a head-up display and Bluetooth connectivity, are found here as well. Thanks to special attention paid to things like door seals and dash insulation, the STS is (according to the company) the quietest GM car ever made.

With a pair of powerful engines (a 255-horsepower V6 and 320-hp V8), a well-sorted suspension that blends a nice ride with athletic handling, and powerful brakes, the STS gives nothing away in terms of overall performance to its closest rivals.

The 2007 Cadillac STS occupies a niche of sorts. Sized more like a full-sizer (at 196.3 inches long, it's 6 inches longer than a Mercedes E-Class) yet priced more like a smaller premium-badged car, the STS would seem to represent a good value. Of course, that would only be true if this Caddy could comfortably compete with cars like the E-Class, BMW 5 Series, Audi A6, Infiniti M35/45 and Lexus GS series. It does suffer in a few areas, such as interior materials quality and the lack of an available manual transmission. But these aren't major issues, and with such a strong, well-rounded personality, the STS has no problem taking on challengers on the world stage.

Body Styles, Trim Levels, and Options

Cadillac offers the STS with a V6 or V8 engine and rear- or all-wheel drive. All versions feature 17-inch wheels, leather seating, aluminum interior trim, eight-way power front seats, dual-zone climate control, remote vehicle start, XM satellite radio, an eight-speaker Bose sound system and OnStar. The V8 version adds a CD changer, memory seating presets, heated seats (front and rear) and steering wheel, real wood trim and rain-sensing wipers. Many of the V8's features can be added to the V6 model via a trio of packages. Other features available on both models include a DVD entertainment and navigation system, adaptive cruise control, a head-up display, and heated and ventilated front seats. An adaptive suspension system (Magnetic Ride Control) is also available, as are larger 18-inch wheels. Available only on V8s are xenon headlamps with washers and the "Intellibeam" system, which automatically controls the high beams.

Powertrains and Performance

STS buyers have a choice of two engines: a 3.6-liter V6 (255 hp and 252 pound-feet of torque) and a 4.6-liter V8 (320 hp and 315 lb-ft of torque). The V6 comes paired with a five-speed automatic transmission, while the V8 is matched to a six-speed automatic. Both transmissions feature regular and sport shift programs. There is also the choice of rear-wheel drive to maximize performance and economy, or all-wheel drive for better all-weather traction. The standard V6 is able to get the big sedan up to speed with surprising gusto. But step up to the V8 and the STS really shows its mettle -- we recorded a 0-60-mph time of 6.3 seconds and a quarter-mile sprint of 14.4 seconds.


Antilock disc brakes, stability control, a tire-pressure monitor and a full complement of airbags are standard on every 2007 Cadillac STS. The airbags include front-seat side and full-length side curtains. In IIHS frontal-offset crash testing, the STS scored a rating of "Good," the highest possible.

Interior Design and Special Features

Eye-catching design, the use of premium materials and overall fine fit and finish mark the Cadillac STS' luxurious cabin. With its eucalyptus wood trim, handsomely stitched leather and waterfall-style center stack, the STS' inner sanctum looks and feels top-shelf. However, there are a few small demerits, such as a few lower-grade plastic trim pieces and an unfinished edge near the nav screen. Most of the luxury features are easy to use, with the exception of the confounding memory-setting procedure for the driver seat, mirrors, radio and climate controls. Unlike traditional systems, which place the buttons on the door or console, you must dive deep into the nav screen to set the memory in the STS. A four-color head-up display, Bluetooth connectivity and an optional 15-speaker Bose 5.1 surround-sound audio system should satisfy the most ardent technophile.

Driving Impressions

The optional Magnetic Ride suspension offers Touring and Sport modes. In Touring mode the Cadillac STS provides a cushy ride and composed handling; indeed, the car will dive into the turns with unwavering composure and never feels as if it's sprung too softly. In the Performance setting, the handling is a little sharper and the ride a bit stiffer, but the STS handles so well in Touring we question the necessity of the two settings. Overall, this large car feels three-fourths its size when driven with enthusiasm, yet it rides like a luxury car when you're spinning up the miles on the highway. Braking is strong as well, with progressive pedal action and an impressively short 120-foot stopping distance from 60 mph.

Well made car

Vehicle: 2007 Cadillac STS Luxury 4dr Sedan (4.6L 8cyl 6A)

This car is a dream. It performs well and looks great. I have had no problems with it. Unless you get a 535i or higher, they do not compare. BMW's are mechanical pieces of junk. You best not keep one after the warranty runs out. This caddy is super, handles extremely well. I also own a 2001 STS. It has 180,000 miles on it, still runs like new. To all the haters, you can put a dead key fob in the center console pocket and the car will work fine. Read the manual. If you want cavernous rear seat room, get the DTS.

Very happy!

I love the V8 AWD, the few thousand is worth it for the AWD option if you are in snow states. Also the magnetic ride control with the available option of riding with performance or touring is great. I love the navigation, once you get it down. it is quite user friendly. Definitely luxurious with the diamond white pearl and the cashmere interior and light brown wood grain! Great sound with the Bose speakers also! HID lights and LED tail-lights. This car is perfect!

Not so good

Vehicle: 2007 Cadillac STS Luxury 4dr Sedan (4.6L 8cyl 6A)

I have enjoyed leasing this caddy. I was so happy the day I picked up. Over the past 3 years the car has had some problem. There was about 4 recalls. I wore a hole through the driver side carpet. The outside chrome has come off. Gas tank lid spring broke. Knobs on the dash have worn off. I only avg 14 mpg. A bit under powered. Trunk and back seat way too small. The rims bust up very easy. Had to replace 2 of them in the past 2 years. The plus is the car looks great and does have a smooth ride. After driving the car for 3 years I would never buy one. Its just not a well made car for a stick price of $54,000.

My last cadillac

Vehicle: 2007 Cadillac STS Luxury 4dr Sedan (4.6L 8cyl 6A)

This is my 3rd or 4th Cadillac (lost count) but it is surely my last one. This little STS has had one annoying problem after another...and NO MILES ON IT!!! This evening it has shut down completely and doesn't recognize fobs, won't open the trunk or move out of PARK. Road Side Assistance sent a tow truck out to carry the car back to the dealer, but, the tow driver couldn't budge the car out of PARK. Thankfully, we are home and have a second vehicle (Toyota) so we aren't stranded. Now, if this was happening at a mall or anywhere on the road, this incident would be more than infuriating. I would not advise anyone to buy a Cadillac.

A sporty luxoboat

I inherited my like new '07 STS this year and it is a pleasure to drive. There are only a few squawks: programming without the nav screen is complex and the drivers seat appears loose (there's a TSB that addresses it) and nitrogen-filled tires are a bit overboard. Aside from those minor criticisms, the car is an excellent performing car. It's rakish looks are complemented by its terrific handling.

Stay away

Vehicle: 2007 Cadillac STS Luxury 4dr Sedan (4.6L 8cyl 6A)

I leased this car, and within the first year, the car was in the shop for over 30 days! It was first a recall, then rattles in the trunk that took three tries to fix, then a blown speaker, then Homelink failures. Unbelievable! I was never offered anything for my troubles by the dealer or GM. Bottom line, I traded for a 2008 335i BMW sedan and could not be happier. BMW offers so much more for the money. Imagine that, a BMW more affordable and a better value than a Cadillac!! The original list on the Caddy was $65,000, and it wholesaled after I traded it in for $25000, and only after 13 months!!
