Driving the redesigned 2006 Chevrolet Impala through the Tennessee backcountry, we found plenty to like about this new full-size American sedan. Putting the Impala SS through its paces revealed fairly tight and responsive steering that allowed for crisp curve carving, and capable brakes that are a step up from the base model’s stoppers, which feature too much squish at the top of the pedal before grabbing. Not surprisingly, the Impala SS’s steering ratio has been quickened, helping it to feel more responsive. Our only complaint about the handling revolves around torque steer when throttling out of turns.

That torque steer underlines the biggest difference between the SS and the standard Impala: engine power. Dip into the throttle, and the 2006 Chevrolet Impala SS makes you think it’s been downing Red Bull, thanks to its flat torque curve, aggressive throttle tip-in, cleaner shifting, higher redline, and a honkin’ growl that is guaranteed to make bobble heads of muscle-car fans. According to Chevy, its acceleration time to 60 mph is less than six seconds, and out on the highway the DOD system makes seamless transitions from eight to four cylinders. In fact, those who get their kicks trying to maximize fuel economy will enjoy watching the DOD cycle on and off through a display in the Impala SS’s Driver Information Center. Note that Chevrolet recommends the use of premium fuel to maximize the Impala SS’s performance, but the 5.3-liter V8 will run just fine on regular unleaded.

After getting our kicks in the Impala SS, we also tried each of the two V6 models, finding both adequate for their missions, but preferring the LTZ model’s stronger 3.9-liter V6, which can nail a 7.8-second sprint to 60 mph compared to the 8.4 seconds it takes the smaller 3.5-liter version used in the LS and LT. Both V6 engines have enough torque on tap, and smooth throttle tip-in as well. Notably, the LTZ’s 3.9-liter V6 employs variable valve timing, a feature seldom seen from General Motors. And the 3.5-liter V6’s fuel economy of 21-mpg city and 31-mpg highway is second in its segment only to its GM stablemate, the Malibu Maxx. Throttle and exhaust notes are not unpleasant, but are bland, like class competitor Toyota Camry.

All 2006 Chevrolet Impalas are noticeably quiet for everyday motoring. Newly-styled windshield wipers, engine covers, large volume exhaust systems, and a mesh air deflector for the available sunroof help to keep the cabin silent. Chevy engineers have also added thicker side glass and have stiffened and isolated the engine cradles to further reduce the intrusion of NVH into the cockpit.

Chevy has also improved the suspension over last year’s model, with new jounce bumpers and tie bars, and revised variable rate rear springs. The result is responsive handling, a controlled ride, and a small amount of body roll in turns. The stiffer suspension in the Impala SS provides even more control. Compared to the Chrysler 300, the Impala SS was easier to steer and brake. And the Impala V6 models were better mannered than the Ford Five Hundred and on par with the Toyota Camry.
