2010 MPG Stats - Post Them Here

no

there have been people here that reporting tracking issues with various MY Pri's.

i have had or have 2004, 2006 and 2010. all have tracked straight to the point i can comfortably (within reason) remove my hand from the steering wheel and not worry about it wandering in its lane.

verify you have no road slant/wind sheer issues and report this to your dealer

 

1175 miles with 3 fill ups so far...averaging 45-47 MPG on the 2010 Prius IV

 

I found these results a little disappointing, since I was doing about the same in my 2006 Prius. Most of my driving is local/short trips, that include lots of little hills and stop-and-go driving, but about 30% has been highway driving -- where the MID was showing 49-53mpg.

7/31 Purchased car - dealer filled tank
8/8 6.98 gallons - Trip A display: 314 miles, 44.90 mpg; calculated: 45.01 mpg
8/18 8.26 gallons -Trip A display: 370 miles, 46.90 mpg; calculated: 44.79 mpg

What's also interesting is that the calculated mpg for my first fill-up, which has to be based on the dealer's fill-up, was actually higher than the computer MID display.

 

I have a model III with sunroof and just finished my first tank of gas. I drive 50 miles to and from work every day, 40 miles of that are on the freeway and I got 52.6 mpg real calculation. The car's estimate was 53.7. That was with the AC running too since it's hot out here. So not so bad. This is my first Prius, I'm not using P&G yet.

 

Yesterday I drove about 30 miles, mainly highway, to the office where I was taking a class and ended up with a trip reading of around 53mpg. Coming back, I had to go to my office in town first, and then drove back home taking a route directed by my nav, which was almost all uphill and roads with a lot of traffic and many lights -- My average speed dropped to 45mpg. This included the 30 miles I had registered at 53 mpg so the mpg for my return trip must have been lower than 45. On my return trip, I felt that the car was almost laboring the entire way. I was continually having to slow down or stop at lights and then start up again. I put it on PWR mode for a while so that it would handle the uphill battle a little better.

 

I just finished a 900 mile round trip from Denver to Sheridan Wyoming (with side trips). Conditions:
- Cruise control set at 77
- heavy winds
- rolling hills and mountains.

At these conditions I averaged 43 MPG

When taking cruise off and the winds had diminished, I got 54

 

I just went through my first tank of gas. My dealer said I had a full tank, but I stopped at the station on put in 1 gallon to make sure it was topped off. Then, I started driving I my first tank. I went 486.6 miles before fueling for the first time, and it took 9.3 gallons. Now, I know I can drive until my last bar is gone, until I fill up again.

So, the display showed 56 MPG, and my actual was 52.3 MPG. Bummer

I was hoping my actual would only be 2 MPG off the display, like many others, and I would be getting 54. However, my next tank may be better. My drive home last night was my best ever. Looking at the 5 minute display, I had 4 over 75, and the other 2 just over 50.

I drive 48 miles to work everyday, with 33 HWY, and the rest suburb driving, plus short trips out a lunch time. I'm going for 55 calculated on my next tank.

 

I own my Prius II for almost a month now. Delivered on 7/29/09. I will post my impressions and things I like and I dont like about Prius in another thread.

Regarding gas consumption, my car has total 895 miles. Today I bought my second tank. My average for the first tank is 51 mpg second tank 53.1 mpg. Those are measured at the pump. The indicator in the car reads about 5 percent more.

I do mostly suburban type of driving. Up and down small hills (SE PA) 5 - 7 mile runs to the grocery store, mall, post office etc. Most of the time ICE has to warm up, which kills my mileage. Still I am averaging 52 miles + per gallon. In my previous car I used to fill the tank at least once a week. Now I am at once every two weeks interval, plus the tank is smaller, therefore it costs me less at the pump.

On average I am saving about USD 100 per month in gas cost only!! Plus (thanks to C4C) I am saving on repairs/maintenance since Prius is a brand new car..

I dont think I will ever go back to a non-hybrid car for daily driving purposes.

I cannot be more happy.

 

Just finished a highway trip.

distance: 479.0km(297.7miles)
mileage indicated: 32.0km/L(75.3MPG)
mileage calculated: 30.1km/L(70.8MPG)
average speed: 80km/h(50MPH)

10	8/24	10.4	575.3	56.5	daily commute

during the break in period, I didn't pay much attention to the pump reading and the display. Also, the road trip really brings down the MPGs, but at least we were comfortable for the ~1900 miles. The car does a lot better on the daily commute ~70 miles a day.

 

My best road trip for fuel consumption to date.

I've had my Prius V with AT (17" wheels) for a little over one month now with display readings averaging about 52 mpg display (50 mpg calculated) for the last three fill ups. Yesterday (Tuesday, August 25, 2009) I had to pick up a couple of instruments that I had repaired up at a Mansfield, Ohio, factory - a 75 mile trip each way from my office/lab in Columbus.

Before leaving I adjusted the air pressure in the Bridgestone tires to 40/39 psi (front/rear) using a newly purchaed $20 digital pressure gauge. Most of the way was on the freeway (I-75). I used the cruise control with the radar set at the closest distance (one bar = about 3 cars lenghts) and, for most of both ways, followed (in an attempt to draft) behind big semi tracter-trailers that were going about 68 mph most of the time.

I got an average of 58.5 mpg (display reading) going to Mansfield without the two instruments and 57.5 mpg at an average speed of 56 mph for the round trip (150.4 miles). Made the same trip 10 days before to drop off the instruments with a round-trip fuel consumption of 55.7 mpg at an average speed of 52 mph.

Apparently, using the cruise control with radar set at the shortest distance and following behind large semi tractor-trailers can improve fuel consumption. Very pleased with results.

 

To each his own but that won't be happening here. Last thing I want to do is stare at the back of a big ugly truck for an entire trip.

 

the only way i would follow that close is with the radar CC. sure as hell wouldnt rely on me to be alert enough in case something happened

 

Per trip A, my average for 3,012 miles is 46.8 ... compared to my other German cars, this is great!

 

Third fill up today:
miles: 549
comp: 56.4
calc: 52.9
temp range: 45-65

I didn't get the average speed for that tank but it is probably around 31 mph.

Getting better FE every tank: 50.9, 51.3 and 52.9 (~1500 miles on car)!

Rats. I'm only getting 47.4 mpg- I've put gas in once and my calculation based on the gas I put in comes in at 49.9. I have had the air on most of the time and am still figuring out how to work things. I find the nav irritating and sometimes wrong. guess i'll have to work on getting higher milage.

 

This is my first hybrid. I'm not much of a hyper-miler as my right foot tends to be a bit lead heavy. I just broke 200 total miles. I haven't had to fill up yet, so I'm just going by the numbers on the display. For the total 200, I'm averaging about 58.0 MPG.
The last two days have been in the 90's in SoCal. So, I decided to do some experimenting during my commute. Using some P&G sporadically (otherwise these SoCal commuters will probably kill me), I was able to return close to 60.5 MPG. This with the AC running at 75 degrees during my afternoon commute.

 

From what I've been able to gleam from the posted records in this thread:

Just FYI,
My data was taken at no A/C use trip.

Most of my driving is very short (less than 5 miles). I finally took a short drive today, nice to see how the MPG changes as it warms up and I get in the groove. Was really pumped to see 100mpg over 10 minutes or whatever. What do the little regenerated cars mean again? (in the graphic)
