Took a trip from here in Dalla to south Texas (Lake Jackson) this weekend, and I watched the gas mileage on the way back. For the first 100 miles, I got 28 MPG. Amazing. The terrain in the south part of Texas is fairly flat, though. For the entire trip, I got 27.3 MPG. Still not bad at all. The altitude down there is near sea level, and Dallas is at about 400 feet, so it's an uphill climb. I have a Steeda CAI and Brenspeed 93 octane tune, and the speed limit on the freeway is 65 or 70, depending on where you are and time of day. I kept to the speed limit. Cops were everywhere.

BTW, I paid $4.15 for 93 octane at a small town in central Texas.

 

i did a 250 mile trip to Reno, got about the same, did the same trip in the wifes prius last yeasr and i actualy got better milage out of the stang? go figuar.....

 

I call BS!

 

I have gotten some great gas mileage out of the stang. If its all flat highway maintaing same speed I have gotten 27+.

 

Most I have gotten recently was 30 mpg the other day coming home from work.. it's a 20 mile trip each way.. so I have been motivated to take it a little easy on the pedal. All I had to do was drive the speed limit (60mph) and take it easy at lights

 

me too....something that is suppose to get 45 MPG somehow only got 30

 

If you say so........
you have to remember the prius is designed for city driving not high way driving.

 

Dude you are crazy, the Prius gets 48 city and 45 highway.
There is no way your Mustang got better mileage, stop BSin us.

 

Fuel consumption
[/align] [/align] The Prius is marketed as a fuel efficient car. In the United States, the Environmental Protection Agency (EPA) test results must be posted on new vehicle windows, and are the only fuel consumption figures that can be advertised. Similar to other vehicles, Consumer Reports viewed the initial estimate as flawed[19] and issued their own assessment[20] giving a real-world fuel consumption of 44mpg–U.S. (5.35L/100km/52.8mpg–imp) for the Prius instead of 55mpg–U.S. (4.28L/100km/66.1mpg–imp) (51mpg–U.S. (4.61L/100km/61.3mpg–imp) highway, 60mpg–U.S. (3.92L/100km/72.1mpg–imp) city. EPA testing procedures for all vehicles were revised in 2007.[21] According to the EPA's revised estimates, the combined fuel consumption for the 2008 Prius is 46mpg–U.S. (5.11L/100km/55.2mpg–imp),[22] making it the most efficient car available in the U.S. in 2008, based on the official rating.[5]

 

Something I've always wondered. Wouldn't a small engine have to work harder to make the same power as that of a V8. Doesn't it take more power to drive 70 mph? If so, then small engine would have to work a little harder than the V8 to drive 70 mph. I dunno, I've just kind of wondered about that.
