2006 Chevrolet Impala Trims

LS

Avg. Price: $8,185

The LS is the base-level trim for the Impala, featuring the most modest power plant and a more basic selection of comfort and convenience amenities. Standard features include air conditioning, full power accessories, a tilt steering wheel, a power driver seat and keyless entry. The LS also features a three-passenger front bench, while the higher trims come with two bucket seats.

The LS is only available with one engine: a new 3.5-liter V6 engine that produces 211 horsepower and 214 pound-feet of torque. This V6 is paired with a four-speed automatic transmission. The LS offers the best Impala fuel economy, estimated at 21/31 mpg.

LT

Avg. Price: $8,628

The LT takes a very gradual step beyond the base level LS trim, by adding a remote vehicle starter to the standard features roster. Like the LS, the LT comes equipped with air conditioning, full power accessories, a tilt steering wheel, a power driver seat and keyless entry.

The LT also gives buyers a choice of engines; the standard 3.5 liter V6 can be swapped for a slightly larger mill. The optional engine is a 3.9 liter V6, producing 240 horsepower and 242 pound-feet of torque. Many reviewers have advised that this level of engine power is the best suited to match the sedan's rather mediocre suspension and steering systems.

LTZ

Avg. Price: $10,014

A new addition to the Impala lineup for 2006, LTZ is a common badging for luxury-oriented Chevy cars. Upscale enhancements at this level include heated leather seats, a premium Bose audio system, 17-inch alloy wheels and an auto-dimming rearview mirror. The front bench is also swapped out for two more inviting bucket seats at this level.

While the LS and LT and both powered by the new 3.5 liter V6, the LTZ upgrades to a standard 3.9 liter V6, producing 240 horsepower and 242 pound-feet of torque. The same four-speed automatic transmission is also paired with this mill. Many reviewers have advised that this level of engine power is the best suited to match the sedan's rather mediocre suspension and steering systems.

SS

Avg. Price: $11,353

The V8-powered SS is a new trim for 2006, replacing last year's supercharged V6 SS.

The sport-focused Impala SS upgrades to a 5.3-liter V8, which generates 303 horsepower and 323 pound-feet of torque. Other performance enhancements include a heavy-duty version of GM's four-speed automatic transmission and a slightly stiffer suspension setup. Despite its larger and significantly more potent power plant, the SS does not loss too much in the way of fuel economy compared to the V6 Impalas; the SS boasts a very reasonable EPA estimate of 18/28 mpg.

The SS is similarly equipped tot he luxury-oriented LTZ, but it gains a few exclusive aesthetic enhancements, including a rear spoiler, 18-inch wheels and a monochromatic finish.
