Powertrain Options and Availability
Two V6 engines and a V8 have been available under Impala hoods, each driving a four-speed automatic transmission. LS and LT 3.5 models used a 211-horsepower, 3.5-liter V6. The LT 3.9 and LTZ contained a 242-horsepower 3.9-liter V6 (later rated to 233 hp). SS models unleashed a 303-horsepower 5.3-liter V8 with GM's Displacement on Demand, which deactivated four cylinders under light throttle conditions to save fuel. For 2007, the fuel-saving system also was installed on the 3.9-liter V6.
