Would hate to see what my Subaru 2003 Baja would get doing a 3 mile commute My commute is 10 miles taking 20 to 30 minutes depending on traffic along back roads.
 
Right now I get 20mpg in the Baja, the 32mpg by prius2007's experience would be nice to see. And looking at the www.fueleconomy.gov site, the low of 37mpg on the 2011's I have sights on would be even better.
 
Thinking of doing a rental from the dealership I plan on buying from for this coming weekend to see what my typical driving might bring. Hefty price tag for the Prius for some of us.

#953 of 982 Mileage on 2008 by sthoge

On my 2008 Prius IV, I get around 45 in the winter and 52 in the summer. I also have a 10 mile commute each way to and from work. It is mostly flat with a couple of hills. The speed varies between 35 and 30 mph. It usually takes around 10 to 15 minutes for it to warm up, then the graph shows a great increase in mileage. Mileage is calculated by hand and tends to be around 2 to 3 mpg below the displayed average.

I agree with you Chip, it is a hefty price tag. I found a 2010 Prius II with 45,000 miles on it for $15,400, and I am very happy with it . . . averaging 49 mpg (51 mpg according to the optimistic Prius computer).
 
Also, the rental is a good idea and you can see what kind of mileage is delivered by your commute conditions. As they say, "Your mileage may avary".

51 mpg calculated after fillup. car's computer said the MPG was 54.6 MPG.
 
Trip A will be reset after each fillup and Trip B will be used to look at the long term mileage...

I have done this for the last 13000 miles (bought it new). On average, my calculated mpg are about 3 less than Toyota calc's when measuring just one tanks worth. (Your Trip A) I get anywhere from 51 to 48. (Significantly lower in winter when temp is down). My longterm (your Trip b) measures 51.8 over last 13000 miles, but calculated it is more like 49.2. Toyota does not calculate averages very accurately.

New to this board and have found it incredibly helpful while choosing a new car! I just bought my 2010 Prius III last week. After 1 tank and around 470 miles, here is my data:
 
Computer 54.3 mpg
Calculated 50.2mpg
 
My drive is 60-70% freewaY. My primary job is 60 mile commute on primarily flat highway. My 2nd job is 20 miles on hilly backroads. Hoping to get my next tank closer to 55mpg... been working on driving techniques I have been reading about around the boards, yt, etc.

For your 60 mile highway commute, what sort of speeds are you driving. For me there's a pretty big MPG difference between a constant 65mph and a constant 75mph. If you can keep your speed closer to 60mph even better.
 
And if you think about it, driving 60mph for your 60 miles will take one hour. If you drove 72mph, then it take 50 minutes. If you drove a constant 60mph you'd probably get close to 60mpg, so that would be on gallon of gas. At 72mph it might be down to 45mpg and you'd use 1.33gal of gas, or about $1.25, or about $2.50 round trip, or about $12.50/week or $600/year.
 
The question is whether or not the $600/year is worth the extra 10 minute commute each way. That's a personal decision. My commute is only 20 - 25 minutes depending on my speed, so for me I keep the speed down to increase my MPG, plus it gives me a chance to listen to more news on the radio driving to and from work.

Use 100% ethanol-free gasoline. 10% ethanol in gasoline loses 2-4% btus compared to 100% ethanol-free gasoline. Also, gasoline engines do not have high compression as actual ethanol engines would have, to be able to access the full energy in ethanol.
 
Go to pure-gas.org to find the 5100(& rising) stations that sell 100% ethanol-free gasoline. Thousands of drivers switching to 100% ethanol-free gasoline show mpg jumps of 6-8%..... some people say they get even higher mpg jumps.
 
Also, gasoline engines running on 100% pure gasoline(no 10% ethanol blends need apply) will run smoother, quieter & have less need to shift down while ascending hills.

For my 60 mile commute, I would say I typically have the cruise set at 65mpg. There is a 5-6 mile stretch where the speed limit is 55, so i tend to slow down to at least 60. I wouldnt care about a 10 min longer commute, but i might have someone up my you know what if i slow down that much! LOL

2nd tank info-
Calculated 53mpg Computer 56.5mpg. I was doing really well on my current tank. Computer was reading 61.5... then it got hot out and I succumbed to AC! Now down to 58.5 per computer.
 
 Question-what are the "ranges" for rpm based on the eco bar? Sometimes i feel like i need alot of umphh, even into power zone to accelerate up any incline.
