2006 Chevrolet Impala SS Sedan

Displacing 5.3 liters, the Impala SS's engine is a member of GM's small-block family of overhead-valve V8s and its all-aluminum construction means it isn't much heavier than the iron-block V6s otherwise installed in the Impala LS, LT, LTZ and 9C1 and 9C3 police packages. Its 323 pound-feet of peak torque at 4,400 rpm, however, is up 43 lb-ft from the 240-horsepower, supercharged 3.8-liter V6 used in the 2005 Impala SS.

To handle the extra twist the Impala has been reinforced. The unibody chassis design carries over but there are thicker frame sections surrounding the engine bay, and the engine and its four-speed automatic transaxle ride in a new extruded aluminum engine cradle. The suspension still uses struts front and rear, rack and pinion steering and four-wheel disc brakes with standard ABS, but the gorgeous 18-inch wheels inside P235/50R18 Goodyear Eagle RS-A tires are new.

Although the 2006 edition rides on the same 110.5-inch wheelbase of the 2005 car, it's a little less than half an inch longer and 106.4 pounds heavier. That's more or less the weight of two additional cylinders plus the bigger wheels and tires minus one supercharger.........Has recently been through an 117-point safety inspection, has been serviced, fully detailed, and is ready to go!!!
