Fuel economy / miles/gallon

[Audio]

I personally can't complain. I knew what I was getting myself into buying a 375HP V8 powered car that weighs almost 4100 pounds. I can have a heavy foot from time to time and see anywhere from 13 to 17 in city depending on how I drive that tank. I had a long distance almost all highway road trip and was over 29mpg average by the time I got home. Absolutely no complaints about that at all.

Yeah. When I google "epa mileage ratings" that is the first website that shows up.

I just followed your directions.... maybe that was my mistake!!

Now I know better than to think "go to the EPA website" actually means "Google EPA website" !!

Here is some interesting information from MotorWeek segment about gasoline octane:

Can confirm that the R-Spec gets an average of 2-3 MPG more on 93 vs 87. Also gets about 20-25 more HP at the top end.

My average on 87 is ~21.5 combined. My joy, however, is pegged at 95-100% when driving, so I say who cares?

my 3.8 AWD gets around 8.5 - 9 L/100 km on the highway cruising at 95 - 100 km/h (59 - 62 MPH), but fares much worse in town, at around 14 - 16 L/100 km (I have a pretty heavy foot in town). Average usually works out to between 11 - 13.5 L/100 km. Which isn't bad for a 320 HP car that weighs 4500 lbs. dry. Its better than my previous 2.0T Genesis Coupe funny enough. Loving the car so far. Apparently its a thief trap though. Hasn't been successfully broken into yet, but doesn't mean people haven't tried.
