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.

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
