Re: 2009 fuel economy
The revised / lowered EPA ratings for my 2008 Impala LTZ with the 3.9 V-6 (using regular gasoline) was rated at 18 city / 28 highway. The car has never achieved that mileage.
The 2009 EPA mpg ratings for the 2009 Impala with the 3.9 V-6 (using regular gasoline) has been revised / lowered again to 17 city / 27 highway.
