2006 Cadillac STS Review

2006 Cadillac STS - V-6 sips gas.

By:

With rising gasoline prices, Cadillac is probably happy it offers a V-6 for its mid-size STS luxury sports sedan because it only offered a V-8 in this country's last two fuel-crunch periods.

In fact, the $41,020 STS V-6 is arguably the best buy with its 3.6-liter, 254-horsepower engine, which provides lively performance. The $47,520 STS V-8 has a 4.6-liter engine that generates 320 horsepower and neck-snapping acceleration.

There's also an all-out-performance STS with a supercharged 4.4-liter V-8 that kicks out 469-horsepower. The STS-V also has unique interior and exterior trim and upgraded mechanical components. But it's very costly at $74,270, and is strictly for those who want the ultimate high-performance STS.

Cadillac builds the STS-V because rival BMW and Mercedes-Benz also offer extreme hot rod versions of their standard luxury sports sedans.

The STS V-6 requires only regular-grade gasoline and provides an estimated 18 mpg in the city and 27 on highways with rear-drive and 17 and 25 with optional all-wheel drive.

Premium fuel is recommended for the V-8, which delivers 17 mpg city and 26 highway with rear-drive and 16 and 23 with all-wheel drive.

Both engines work with a smooth, responsive five-speed automatic transmission with a manual shift gate, which works well, but is superfluous for anything but, say, mountain driving.

One shouldn't expect much fuel economy from the sizzling STS-V because the car doesn't provide it, at 14 city and 20 highway. It has a six-speed automatic and isn't offered with all-wheel drive.

Those considering the $1,900 all-wheel-drive system should save their money because it really is- n't needed for even Chicago area winter driving. That's because the STS has standard anti-skid and traction control systems to keep the car stable on slippery roads.

The STS arrived as a redesigned rear-drive model for 2005, replacing the aged front-drive Seville STS. The new STS was a hit. Sales totaled 33,497 cars in calendar 2005, compared with only 9,484 in 2004.

Sales of the STS slipped in the first three months this year to 5,625 units from 6,871 in the same year-earlier period, as sales of most U.S. cars dipped.

I've driven the STS V-8, but recently tested the latest STS V-6. It again reminded me that Cadillac didn't design the STS to be a head-to-head rival to European luxury sports sedans from Audi, BMW or Mercedes-Benz.

Rather, Cadillac has made the STS a little softer than those cars so it doesn't alienate older loyal Cadillac buyers, although most such folks opt for the more traditional full-size Cadillac DTS, which has front-drive.

Steering is quick, and ride and handling are good -- as is braking. The STS still is a step or two behind those European sedans when driven hard, but is generally more comfortable. And how often can you safely drive a sports sedan hard in this area?

The STS is packed with standard comfort, convenience and safety equipment. The STS V-8 just adds the extra two cylinders and different tires, although the V-8 makes the car a little smoother and quieter -- besides providing swifter acceleration.

There are numerous, enticing option packages and stand-alone options. For instance, my test car had the $2,640 luxury package, which contains heated front seats, wood interior trim, upscale sound system with an in-dash 6-disc CD changer and 17-inch polished aluminum wheels.

Most options are in the pricey option packages. Key stand-alone extras include a $1,200 power sunroof for the STS V-6 and V-8 and a $2,590 navigation system for the STS V-6. (That system is offered in a $4,445 option package for the STS V-8.)

Four tall adults easily fit in the nicely built STS, and it can accommodate five if the rear center passenger doesn't mind sitting on a stiff section of the seat. The upscale interior is quiet, with supportive seats, highly legible gauges and easily reached controls designed for no-fuss operation.

The trunk is long and deep, with a low, wide opening.

It can be difficult for some to ignore the allure of the 320-horsepower STS V-8, but the best-value STS is the V-6 rear-drive version with few, if any, options. 

2006 CADILLAC STS 

PRICES: $41,020-$74,270

LIKES: More economical V-6 available. Very fast with V-8. Smooth ride. Good handling.

DISLIKES: Costly STS-V version has limited appeal. Not as sharp as harder-edged European sports sedans.
