2008 Cadillac STS Review

KBB Editors

By KBB Editors

Updated December 23, 2019

Our editors drive and evaluate hundreds of new cars every single year, turning thousands of miles and countless hours behind the wheel into helpful reviews, ratings, and comparisons. They also have lives outside of work, or so they think. You’d be surprised what you can learn by hauling a dirt bike, hunting for a wayward sippy cup, or just packing the trunk full of groceries.

Pros

Head-over-heels in love with the original CTS-V’s good looks, but crave the technical wizardry and opulent interiors associated with BMW and Mercedes-Benz vehicles? If you can swing the higher price tag, the 2008 Cadillac STS-V can satisfy both demands.

Cons

In the eyes of many status seekers, BMW’s blue and white propeller badge easily trumps Cadillac’s wreath and crest. If image is more important than performance, the STS-V’s impressive statistics may not be enough to overcome its Detroit background and reputation.

What's New?

New features include Lane Departure Warning and Side Blind Zone Alert. A new 100,000-mile warranty now covers all Cadillacs.

The verdict is in on the 2008 Cadillac STS-V: It’s an unmitigated success. Some had doubts a Cadillac could ever play in the same arena as the famed M cars from BMW, the AMG offerings of Mercedes-Benz or the R models from Jaguar, but the STS-V has left even its harshest critics slack-jawed. Why? Here’s part of the reason: A 469-horsepower supercharged V8 teamed to a super-taut chassis and a fluid body with razor-sharp good looks. The STS-V has the acceleration (zero-to-60 miles per hour in less than five seconds), braking and handling to place it among the world’s best, making it easy for proud American driving enthusiasts to get behind the wheel. It also includes all the luxury one would expect from America’s quintessential luxury car manufacturer.

2008 Cadillac STS Pricing

2008 Cadillac STS pricing starts at $4,476 for the STS Sedan 4D, which had a starting MSRP of $43,135 when new. The range-topping 2008 STS STS-V Sedan 4D starts at $10,817 today, originally priced from $79,000.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2008 Cadillac STS models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the Cadillac STS

The STS-V’s sport-tuned suspension is an impressive piece of engineering, holding the car tightly in the sharpest curves while delivering excellent feedback to the driver through the nicely-weighted steering and responsive brakes. There’s no shortage of power from the supercharged V8 engine, which propels the 4,300-pound STS-V like a rock leaving a slingshot. While it isn’t as fluid through a canyon run as some other factory-tuned sedans, the STS-V’s sport-tuned suspension delivers impressive cornering limits. To ensure the STS-V’s abundant power doesn’t overwhelm the driving experience, Cadillac has created a unique four-mode version of its StabiliTrak stability control system, with settings for comfort, sport and competitive driving styles. The system seems to work best in the sport mode, delivering a balanced combination of ride comfort and handling.

Interior Comfort

The 2008 Cadillac STS-V’s cabin may be the most handsome interior ever produced by Cadillac. Supple leather covers the seats, steering wheel, door panels and dashboard. The clean simplicity of the STS-V’s center console is highlighted by a large touch-screen display for the audio and navigation systems, while a separate panel for the heating and ventilation controls resides beneath. The stalk-mounted cruise control switch struck us as outdated; we prefer this function to be placed on the steering wheel, where it’s more easily operated. As for Cadillac’s sport seats, we can confirm the suede inserts help keep occupants in place, but a bit more side bolstering would accomplish the same goal while providing much-needed lateral support.

Exterior Styling

The same stylistic gene pool that spawned the CTS sedan and XLR roadster also gives birth to the 2008 Cadillac STS-V. The car’s angular lines and upright profile distance it from the rounded contours found on most of its competitors and create a bold look that is uniquely American. Cadillac’s V-treatment takes this visual statement one step further, applying stainless-steel mesh to the grille and lower air intake and lowering the front and rear fascias. To make space for the engine’s supercharger, Cadillac sculpted a subtle bulge in the center of the STS-V’s hood, giving it a menacing stance slightly reminiscent of a 1960s-era muscle car. Keeping the STS-V firmly planted on the road are 18-inch wheels up front, with 19-inch wheels in the rear.

Favorite Features

Head-up Display
The Head-up Display works by projecting a digital readout onto the lower portion of the windshield. Without ever removing your eyes from the road, you can view pertinent information about speed, audio and cruise control settings.

Adaptive Remote Start
Cadillac’s remote start not only allows the car to be started from as far away as 200 feet, but it can also activate a number of preset commands, including operations for heating, air conditioning and defrost.

Standard Features

Standard equipment for the STS-V includes Brembo four-wheel anti-lock disc brakes (ABS), StabiliTrak stability control, a limited-slip rear differential and a six-speed automatic transmission with manual-shift mode. Inside, the STS-V features front and rear side-curtain airbags, Side Blind Zone Alert, Lane Departure Warning, Bose 5.1 Studio Surround Sound audio with MP3-capable six-disc CD changer, GPS navigation, OnStar, cruise control, Head-up Display, dual-zone automatic climate control, eight-way power front seats, heated front and rear seats, remote start, power tilt/telescoping steering wheel, High-Intensity Discharge automatic headlamps with washers, power sunroof, a heated windshield washer system and Ultrasonic Rear Parking Assist.

Factory Options

The STS-V’s option list is a short one. You can add cross-drilled brake rotors for enhanced fade resistance and equip the engine with a block heater. You can also order your STS-V without the power sunroof.

Engine & Transmission

The 2008 Cadillac STS-V employs a variation of Cadillac’s all-aluminum Northstar V8 engine. The 32-valve, 4.4-liter powerplant features dual overhead camshafts and variable valve timing (VVT) for improved efficiency. Cadillac engineers then added a supercharger that forces air into the engine’s combustion chambers, thus increasing horsepower and torque. The added power can mean added stress to the engine, so internal components such as the pistons, connecting rods, cylinder heads and camshaft have all been strengthened accordingly.

4.4-liter V8 Supercharged
469 horsepower @ 6400 rpm
439 lb.-ft. of torque @ 3900 rpm
