I find it iteresting that they end the article talking about fuel mileage. I just had a Chevy Impala, daily rental car in Ohio this week. I did mostly highway but I was also in quite a bit of stop-and-go city driving so it was an 80-20 mix. I drove at about 70 mph (not 55 or 60) on cruise control on the highway and the car's computer was indicating an average of 35 to 36.5 mpg most of the time.

It only took 10.5 gallons to do 323 miles which works out to 30.8 mpg overall. I have no idea how many miles were put on the previous full tank of gas before I picked it up at the airport but it is safe to assume around 20 miles (customer fills up, drives to airport, rental company takes car to be washed, etc, car is moved back to the airport garage). So an additional 20 miles on that 10.5 gallons would give 32.7 mpg combined highway and city driving.

I think that is excellent mileage for a full size car so GM is doing some things right.
