This beauty of a vehicle literally defines the combination of high performance and pure luxury. Producing a thundering 469 horsepower and 439 lb-ft of torque the supercharged 4.4 Liter Northstar is the most powerful Cadillac engine available. Blasting this 4,233-pound collection of exotic steel, leather and wood from a dead stop to sixty miles per hour takes less than five seconds.

Few luxury vehicles have more than 300 horsepower and the 400 plus club is an exceedingly elite group. Cadillac accomplishes this performance with amazing grace and fuel economy ratings of just 14 MPG in the city and 20 MPG on the open road. However with your foot in the gas and the supercharger screaming, economy is a mere fantasy.

The 2007 Cadillac STS-V is not just about horsepower and 0-60 times. The STS is a true drivers car from Cadillac. Based on a stretched CTS platform, many feel that there is not enough distinction between the two models. But the STS is certainly upstream from the CTS in regards to luxury appointments as well as driving technologies. The STS-V competes well with the very best that European and Asian manufacturers offer.

It's a mistake to compare the 2006 Cadillac STS-V with the base STS. Equipped with a 255 horsepower V6, the base STS can be stripped down to a $41, 740 MSRP while the STS-V offers no additional options for a hefty $77,090 price tag. Is the STS-V worth an additional $35,350? Only you can answer that question, but I can tell you that there is little comparison between the two vehicles. The premium options found on the V-series cars place them in a category all by themselves. The drawback to engineering over-the-top performance on an existing vehicle is that it retains the limitations of the original platform.

Therefore the STS-V still suffers from a cramped entry and exit, especially for rear seat passengers. The STS-V is limited only by the original platform and fortunately it's an adequate foundation.

With the STS V, it's all about the driving. Suspension is upgraded for superior handling with a 4-wheel independent design utilizing a short/long arm, coil-over strut with anti-sway bar in front, and a modified multi-link with anti-sway bar and automatic level control system in the rear.

Huge 14-inch rotors on both the front and rear are shod with Brembo high performance vented ABS disc brakes using 4 piston calipers. Big brakes require big wheels and tires. Pirelli P255/45WR18 are mounted on cast aluminum 18-inch wheels up front while 19-inch 40 series tires provide rear traction.

The 2006 Cadillac STS-V is a remarkable blend of luxury and very high performance, making it one of the very best sedans on the market at any price.
