The modern Chevy Impala produces respectable fuel economy for a large sedan. When equipped with either the 3.5 or 3.9 liter six-cylinder engine, the roomy Impala’s gas mileage rating falls between 27 and 29 miles per gallon on the highway. Results with the 5.3 liter V-8 (last available in 2009) aren’t anything to sneeze at either, with a rating of 16 city / 24 highway. The Impala is a big, comfortable ride that’s conservatively priced and well suited to soaking up the highway miles.
A significant number of E85-capable FlexFuel Impalas were produced over the years. While these older engines were not optimized to achieve great fuel-efficiency with E85, the ability to run locally-produced ethanol may be advantageous in certain locales and instances. With the proverbial still in your shed, you can enjoy big (domestic!) car comfort without sending your fuel dollars overseas.
While all the chrome, the two-tone paint and the fins may be long gone, the Chevrolet Impala is still a king of the open road and a true slice of Americana, with a long and storied past that dates all the way back to the 1950s. And ready-or-not, the latest update might just bring back memories of the performance-oriented Impala SS.
Although long overdue for a platform and design update, the 2012 Impala offers significantly more power as well as a slightly higher level of fuel-efficiency, as it continues to offer FlexFuel-capability. The addition of a direct-injected 3.6-liter V6 engine and six-speed automatic transmission in the 2012 Impala promises to deliver 18 MPG city / 30 MPG highway with conventional regular unleaded gasoline.
The 2012 Impala’s 3.6-liter V6 is rated at 300 horsepower (HP), a significant jump from the previous model’s 211 HP 3.5 and 230 HP 3.9 V6 engine choices. Needless to say, we look forward to road tripping Chevy’s big four-door sedan in the near future.

Note: the EPA tweaked their testing procedure, starting with the 2008 model year, with the end result being that the 2008 MPG estimates are now lower than previous years. As always, YMMV.

Real world observations:
2006 and 2007 Impalas, 3.5 v-6, rented a year apart for 1400+ mile trips.
Speeds kept at posted limits – 65 & 75 on highway and interstate. Full use of cruise, occasional A/C.
Mountain passes through CO, ID, UT, MT, OR.
Average mpg for 2006 – 30-32.
Average mpg for 2007 – 32-34.
Recently tested 2008 LTZ with 3.9. Computer indicated mpg hovering just under 30.
Note that the final drive ratio (like the old ‘rear end ratio’ for FWD) for the 3.5 car is tall – something like 2.79 or 2.89. The 3.9 car is lower – something like 3.29. The rpm’s were noticeably higher at the same speed than the 3.5 car.
While the 3.9 car felt much stronger, it’s not much more powerful, and the lower gearing could account for the better acceleration and lower mileage. The cylinder deactivation didn’t seem to do much.
I’d like to get a 3.9 car and have the shop change it to the final drive ratio of the 3.5 car. Too bad GM doesn’t offer options like that any more.
