Benefits of Driving a 2009 Cadillac STS Sedan

The 2009 STS occupies a slot in between the CTS and DTS in Cadillac's lineup. In terms of performance and features, it is every bit a rival to the top sedans from Germany and Japan. With all-wheel drive, the STS makes a surprisingly good all-weather car, and with its front-wheel steer system, the AWD V8 model is especially safe and nimble. Inside, the STS has a look and feel that entirely justifies the price, plus convenience and safety features that compete with the best in its class.

What's new for 2009?

For 2009, Cadillac's STS and STS-V get mostly superficial changes following the 2008 refresh. Exterior colors Radiant Silver, Black Ice, and Blue Diamond Tricoat replace Blue Chip, Radiant Bronze, Light Platinum, and Sunset Blue. A speed limit notification has been added to navigation radio, and a Bluetooth interface is now available on non-navigation-equipped STS models. The Platinum Edition receives an alcantara ultra-microfiber headliner.

TheCarConnection.com goes the distance to bringing you the best and most complete information available on the 2009 Cadillac STS. Experts have combed the Web to bring together diverse observations; these are then available with firsthand driving impressions and insights from TheCarConnection.com editors.

The 2009 Cadillac STS is the luxury make's mid-size sport sedan. Unlike the front-wheel-drive STS of many years past, the STS has been primarily rear-wheel drive since 2005, sharing some of its underpinnings with the smaller Cadillac CTS. All-wheel drive is also available throughout the STS lineup.

The Cadillac STS saw some slight styling changes for 2008, including a new nose and wider grille, along with some engine updates, and they carry into 2009 with few additional changes. From the outside, the 2009 STS has a unique blend of angular proportions and smooth, continuous sheetmetal surfaces combined with simple but classy detailing, which still makes the design feel contemporary even if it's no longer fresh.

Overall, the 2009 Cadillac STS bears a strong family resemblance to the smaller CTS sport sedan, and it has a similar mix of aggressive, assertive exterior styling, but its interior feels softer and more luxurious. Seating rivals that offered by the German competition; it's amply proportioned and very supportive, with plenty of space in front, but the backseat is barely roomy enough for average adults.

The Cadillac STS comes in three flavors for the 2009 model year. There's a new base engine: a 3.6-liter, 302-horsepower direct-injection V-6 teamed with a six-speed automatic. A 4.6-liter, 320-hp V-8 with a six-speed automatic transmission slots in above it, while the top rung on the STS ladder is occupied by the performance-oriented STS-V and its hand-built 469-hp, supercharged V-8. V-6 and V-8 models can be specified with rear- or all-wheel drive, but the STS-V only comes with rear-wheel drive; all have an excellent six-speed automatic with tap-shift controls. The STS-V can accelerate to 60 mph in less than five seconds.

A performance handling package is offered on every model aside from all-wheel-drive V-6 editions of the 2009 Cadillac STS and includes 18-inch chromed wheels, Michelin summer tires, and the larger Brembo four-piston brakes. The STS-V also rides on larger wheels and tires, with stiffer stabilizer bars, a quicker steering ratio, and a specifically tuned chassis; Brembo brakes are included with larger rotors, pads, and calipers.

Between the V-6 and V-8 versions of the 2009 Cadillac STS, the V-6 makes the most sense. It's nearly as fast as the V-8 model, and it saves fuel, with much better ratings of 17 mpg city, 26 mpg highway (versus 13/19 mpg for the V-8). With either STS configuration, you can expect brisk acceleration, sharp handling, and better steering feel than rival vehicles from Germany. Both models have a rather firm ride, but thanks to the standard Magnetic Ride Control, which can make almost instantaneous adjustments to damper firmness, ride comfort is quite smooth.

The 2009 Cadillac STS sports a heated, wood-trimmed steering wheel, a head-up display (HUD) on V-6 models, and more metallic trim integrated into the center stack, though the instrument panel won't be to everyone's liking. The layout, with some screen-driven controls and quite a few small buttons, can be confusing, and the materials haven't been upgraded to the extent seen in the CTS.

Technology is one of the STS's best selling points. Available features include an Easy Key keyless entry system, Adaptive Remote Start system, Adaptive Cruise Control, Intellibeam headlights, four-color HUD, and heated and ventilated seats. In 2009, the eNav system becomes a standard part of OnStar Turn-by Turn navigation.

Intellibeam headlamps are also on the options list for the 2009 STS; they sense approaching taillights or headlights and dim themselves accordingly. Other technological upgrades include revised stability control, a lane-departure warning system, and a blind-spot warning system.

Standard safety equipment includes front side airbags, head-protecting side-curtain bags, and electronic stability control--all expected features in a luxury sport sedan. Based on crash-test results, the 2009 Cadillac STS is in the middle of the pack in safety. Four-star results are awarded by the federal government in all but side protection for rear-seat passengers (five stars), and the STS earns "good" results in frontal-offset protection, "acceptable" results in side impact, and "poor" in rear impact insurance industry (IIHS) tests.

The Bottom Line:

The 2009 Cadillac STS isn't a standout for looks, but you'll appreciate the way it drives.

Safety Ratings help

What do the Safety Ratings mean?

The National Highway Traffic Safety Administration (NHTSA) performs independent crash testing of new vehicles and then assigns them a score based on their performance. The overall crash test rating is based on how a vehicle performs in the following tests:

Driver Crash Grade:

Measures the chance of a serious injury to a crash test dummy that is placed in a driver's seat and driven into a fixed barrier at 35 MPH. A five-star rating means there is 10 percent or less chance of injury.

Passenger Crash Grade:

Similar to the driver crash grade, only now the focus is on the passenger.

Rollover Resistance:

Simulates an emergency lane change to measure the likelihood of a vehicle rolling over. A five-star rating means there is 10 percent or less risk of rollover.

Side Impact Crash Test - Front:

Focuses on the front side of a vehicle. It simulates crashes that can occur in intersections by striking a 3,015-pound weight against the side of a vehicle at 38.5 MPH. A five-star rating means there is 5 percent or less chance of injury.

Side Impact Crash Test - Rear:

Similar to the front side impact test only now the focus is on the rear passenger.

Original Warranty  help
Original Warranty
An original warranty is the warranty associated with a vehicle when it is brand new. In addition to the original warranty, select items, like tires, are typically covered by respective manufacturers. Also, an act of Federal law sometimes provides protection for certain components, like emissions equipment.
The original warranty is often broken down into multiple sections, including:
Basic Warranty:
Typically covers everything except for parts that wear out through normal use of the vehicle. Examples of non-covered items are brake pads, wiper blades and filters.
Drivetrain Warranty:
This warranty covers items the basic warranty does not protect. Wear and tear items such as hoses will not be covered, but key items like the engine, transmission, drive axles and driveshaft often will be.
Roadside Assistance:
The level of service differs greatly with this warranty, but many manufacturers offer a toll-free number that helps provide assistance in case you run out of gas, get a flat tire or lock your keys in the car.
Corrosion Warranty:
This warranty focuses on protecting you from holes caused by rust or corrosion in your vehicle's sheet metal.
Please check the owner's manual, visit a local dealership or look at the manufacturer's website to learn more about the specifics of the warranties that apply to a vehicle.

Basic 4 Years/50,000 Miles
Drivetrain 5 Years/100,000 Miles
Corrosion 6 Years/100,000 Miles
Roadside Assistance 5 Years/100,000 Miles

Cadillac Certified Pre-Owned Warranty  help
Certified Pre-Owned Warranty
To be eligible for Certified Pre-Owned (CPO) status, vehicles generally must be recent models with relatively low mileage. CPO vehicles must also pass a detailed inspection, outlined by the manufacturer, which is measured by the number of inspected points.
Warranty coverage can vary from one manufacturer to the next. While most certified pre-owned programs transfer and extend the existing new car warranty terms, others offer a warranty that simply represents an additional year and mileage value. Always check with the manufacturer for the specific warranties they offer.
Common features and benefits of Certified Pre-Owned warranties include:
Age/Mileage Eligibility
To even be considered for certification, a car must be a recent model year and have limited mileage. The exact requirements are established by individual manufacturers.
Lease Term Certified
Some manufacturers offer certified pre-owned cars for lease. The length of the lease is often shorter than a new car lease, but it will cost you less.
Point Inspection
These inspections entail a comprehensive vehicle test to ensure that all parts are in excellent working order. The point inspection list is simply a numbered list of exactly what parts of the car are examined. While many inspections range from a 70- to 150-point checklist, most are very similar and are performed using strict guidelines. Ask your local dealer about specific details.
Return/Exchange Program
Some manufacturers offer a very limited return or exchange period. Find out if you will get the sales tax and licensing/registration fees back should you return or exchange the car.
Roadside Assistance
Most certified pre-owned programs offer free roadside service in case your car breaks down while still under warranty.
Special Financing
Reduced-rate loans are available through many certified pre-owned programs. Manufacturer-backed inspections and warranties help eliminate the risks involved with buying pre-owned, so buyers who qualify can take advantage of the great offers.
Transferable Warranty
When a new car warranty transfers with the certification of the car and remains eligible for the next owner, it is known as a transferable warranty. Once the original transferable warranty expires, an extended warranty takes effect.
Warranty Deductible
This is the amount for which you are responsible when repair work is performed under the warranty. Some manufacturers require a deductible while others don't, so always ask.
