ACCELERATION
| V6 | STS-V | Class Average |
|---|---|---|
| 7 | 9 | 7 |
The new V6 engine provides strong acceleration from a stop and has outstanding passing power. Cadillac claims a V6-powered STS will reach 60 mph in 6.5 seconds, which feels accurate to us. STS-V models are even more potent. Cadillac estimates 4.8 sec 0-60 mph, and it feels every bit that quick. No V8 models have been made available for us to test.
FUEL ECONOMY
| V6 | STS-V | Class Average |
|---|---|---|
| 4 | 2 | 4.7 |
In Consumer Guide testing, an STS-V averaged just 13.7 mpg. We've not had an opportunity to measure with the V6. V6 STS models use regular-grade gas. Premium is recommended for the 4.6 V8 and required for the STS-V.
RIDE QUALITY
| V6 | STS-V | Class Average |
|---|---|---|
| 8 | 7 | 6.6 |
STS blends absorbency and firm composure to good effect with the base suspension and standard 17-inch tires. The optional Performance Handling Package is almost as comfortable, but triggers mild jitter on coarse or rippled surfaces. The STS-V is surprisingly supple, with a ride that mimics the base setup.
STEERING/HANDLING/BRAKING
| V6 | STS-V | Class Average |
|---|---|---|
| 7 | 8 | 7.1 |
Any STS corners with poise and modest body lean, particularly the sharp STS-V. Compared with midsize cars from BMW and Mercedes-Benz, however, the steering on this Cadillac feels somewhat vague and overassisted. Reassuring brakes provide short, straight simulated panic stops.
QUIETNESS
| V6 | STS-V | Class Average |
|---|---|---|
| 8 | 7 | 7.1 |
Road and wind noise are both well muted. The new V6 sounds refined when accelerating and is otherwise quieter than the engine it replaces. There's slightly more road noise with the STS-V.
CONTROLS
| V6 | STS-V | Class Average |
|---|---|---|
| 8 | 8 | 6.2 |
STS has relatively few buttons compared with other premium cars--a big plus. All controls are easy to reach, though some markings are confusing. The available navigation system absorbs many audio functions but doesn't complicate their use.
DETAILS
| V6 | STS-V | Class Average |
|---|---|---|
| 7 | 7 | 7.5 |
Interior materials quality is good when compared to domestic-branded premium sedans but falls just shy of the standards set by German and Japanese rivals.
ROOM/COMFORT/DRIVER SEATING (FRONT)
| V6 | STS-V | Class Average |
|---|---|---|
| 7 | 7 | 7.4 |
Good headroom and legroom, but some testers feel hemmed-in by the wide center console and high windowsills. The standard power tilt and telescopic steering wheel helps dial in a comfortable driving stance.
ROOM/COMFORT (REAR)
| V6 | STS-V | Class Average |
|---|---|---|
| 5 | 5 | 5.4 |
Disappointing for a car this large. With the front seats set far back, legroom is limited and foot space is tight. The seat itself is well contoured and offers good back support, though a longer seat bottom would enhance long-distance comfort. Headroom is just adequate.
CARGO ROOM
| V6 | STS-V | Class Average |
|---|---|---|
| 3 | 3 | 4.1 |
Trunk space is unexceptional for STS's exterior size. The trunklid hinges don't intrude into the cargo area, and liftover is low. However, a small opening limits the size of items that can be loaded. Small-item storage is limited to a smallish center console and less-than-generous glove box.
VALUE WITHIN CLASS
| V6 | STS-V | Class Average |
|---|---|---|
| 6 | 4 | 6.5 |
STS impresses dynamically, and the availability of all-wheel drive is an asset. Inside, STS disappoints with subpar rear-seat space and materials that are not in step with class pacesetters--or other Cadillac models. On any model, extra-cost items can quickly add to the price, making a judiciously optioned V6 model the best value in this line.
