2006 Cadillac STS-V Review

A powerful luxury sport sedan.

Reviewed by Automotive on


Not long ago, Cadillac automobiles had lost their popularity in the car market. But a nice turn-around happened when the brand introduced the STS, replacing the formerly-popular Seville luxury sedan. And now, Cadillac has expanded their V-Series with the high performing STS-V.

An automatic six-speed transmission with a manual shifting feature conveys power to the Cadillac’s rear wheels and Pirelli tires. The diameter of the upsized brakes measure 14 inches in the front and 14.3 inches in back. Small touches of aluminum on instrument bezels and the steering column and wheel are the most radical you will see in the STS-V interior. Most features of the interior come standard, and seats have added bolsters with suede inserts that hold you and passengers in place if you drive immaturely. On the exterior, you can’t miss the metal grilles, rear deck spoiler, and front spoiler. If you want a sport sedan, the 2006 Cadillac STS-V deserves a look. It provides an interesting alternative to the Jaguar S-Type R and the Mercedes E55.

What's New

Cadillac follows up the STS sedan with the introduction of its STS-V variant for 2006. It features a V-8 supercharged engine, upgraded braking and suspension hardware, larger wheels, enhanced aerodynamics, and a classier interior trim.


The beautiful exterior of the 2006 Cadillac STS-V has a choice of Black Raven, Light Platinum, or Stealth Gray colors. Standard features include a sunroof, HID headlights, rear parking assist, and aerodynamic enhancements. The ?V? in the name stands for the fact that the automobile comes with 19-inch wheels in the back and 18-inch wheels on the front, along with the quicker steering, limited-slip differential, and performance-tuned suspension. Brembo oversized disc brakes come standard, as well as a rear spoiler and a chrome grille.


The STS-V’s extra wheelbase of almost 17 inches allows for more than ample legroom in the rear seats, which is much more than the competition’s. The luggage capacity remains simply adequate with the 13.8 cubic feet of storage space.

Some of the interior standard features include air-conditioning, cruise and audio controls placed on the steering wheel, satellite radio, a leather steering wheel, a surround sound Bose 15-speaker audio system, a DVD-based navigation system, and six-CD in-dash changer. The sport seats have perforated suede inserts and the special aluminum and wood accents add just the right touch of elegance to the cabin.

Performance & Handling

The 2006 Cadillac STS-V installs a supercharger on top of its Northstar V-8 engine, creating the best Cadillac engine that the brand has ever had. Engineers redesigned all major components in the Northstar motor, reducing displacement in the engine to 4.4 liters from 4.6 liters, and the compression ratio dials back from nine to one. A unique system, patented and engineered for air induction, allows the air to enter through the rear, pass through turning vanes at the bottom, and cool by an intercooler as it heads down to the intake manifold. It all neatly fits under the bulging hood of the STS-V, cranking the horsepower from 320 up to a delightful 469 hp. In less than five seconds, the Cadillac STS-V accelerates from zero to 60 mph. The STS-V’s power moves towards the rear wheels via an automatic six-speed transmission that has manual-shifting control.

As a serious performance automobile, the Cadillac STS-V can overtake slow-moving cars with ease. Driving the STS-V offers an amazing experience considering its size, until it comes to cornering. It nevertheless proves to be as competent as any sedan in its class. The larger wheels, sport-tuned suspension, and big Brembo brakes make the Cadillac STS-V a very worthy package for most drivers.


The Cadillac STS-V has stability control, side airbags for the front, an engine immobilizer, head airbags for rear passengers, and traction control as standard safety equipment. The STS-V has not been crash tested by the IIHS or the NHTSA.
