Real World MPG Numbers

1st fill up:
370 mi
6.934 gal
53.4 calculated MPG

Note that this is with snow tires (Nokian Hakkapeliitta R2), my daily commute takes place over an 800 foot elevation difference (6400 feet to 7200 feet), and the average temp here in Colorado Springs has been below 20 in the mornings.

Edited to add: I admit being a bit giddy at paying only $11.50 for 2/3 of a tank of gas. My last car (BMW X1) would have cost at least $30.

 

OK, did any of the new owners get sub 50 MPG on the whole tank? It' winter in northern hemisphere and I'm at 45 MPG in Gen3.

 

Our 2010 Prius now with 136,000 miles, mpg 45 winter, 55 summer. Pretty consistent. I don't hypermile just drive and keep up with traffic.
Here in Winter in Northwestern Oregon rain is common along with 40 degree temps. With rain and standing water on the road it sure drops you mpg quite a bit.

 

Using the throttle EV in and out method I discovered last night, (also posted in What is the Max EV speed no ICE | PriusChat ) I was able to get 71.4mpgs on the same trip back home. No traffic, averaging 61mph.

 

love it!

 

That freakin rocks! I need about 70f, very light wind or a tail wind, 62 mph max and a perfect trip to crack 70 in my HCH over my 30 mile commute. With the new HV battery I'm hoping it will be easier. Don't get to drive the v much, but have pulled short P&G segments in the 60s and 70s.

 

Has anyone done any long jaunts on the Interstate yet? My wife's commute is about 40 miles one way averaging 75 mph and our Gen 3 2010 Prius in the past would've averaged around 44 mpg at best at this speed (of course depending on wind, temp, etc.). Currently she's driving a BMW 328d Sports Wagon and getting right at 40 mpg. We might consider the Prius next time around depending on what people are getting at higher speeds. Hard to give up the better drive and AWD, but we really like the idea of getting the best fuel economy possible and gaining Toyota reliability over BMW.

Thanks to all you early owners for posting your experiences!

 

I just turned 400 miles and am at 57.6 MPG overall, about 300 of that was highway 65-75 MPH. I'm sure it will do much better than that because where we bought it was 1100 foot altitude and we drove it home 110 miles to an altitude of 5000+ feet. Made another trip down the hill and back home today to reach the 400 miles. I have done many trips like this in my 05 and can tell you that under similar conditions and only going down the hill and back up once, the MPG would be no higher than 45-47. We're taking it on a trip to Vegas next week so I'll let you know how it does on longer freeway drives.

 

Prius uses cheapest gas? My first fill up is coming up

 

yes, 87 octane.

 

Using premium gas is a real turnoff. Our 2014 Volt uses Premium gas, the Prius, good old regular for
a lot less money. Though the Volt does run fine on regular but according to the manual premium is required
not recommended.

What is the compression ratio for the 2016 Prius engine? I believe our 2010 Prius is 13.1 or so, atkinson cyle..

 

I don't remember seeing data for the 2016. I'd expect the compression ratio to be similar to the Gen 3 but perhaps a bit higher as IIRC, they have done things to reduce hot spots in the cylinders.

Regarding the Gen 3, 13:1 sounds more like the expansion ratio. The compression ratio would be a lot less due to the Atkinson cycle

 

Here are some "Real World MPG" numbers from Motor Trend's latest comparo between the '16 Prius & the '16 Chevy Volt.

2016 Chevrolet Volt vs. 2016 Toyota Prius Comparison

To quote the article "[The '16 Li-ion (non Eco) Prius] city-cycle Real MPG of 56.5 mpg toppled the EPA’s 54, its 53.4 on the highway stomped EPA’s 50, and our combined 55.1 walloped the EPA’s 52. Wowee kazowee. That’s 7 percent better on the highway and 6 percent better overall."

Yet if you go to their "Real MPG" estimator- Motor Trend claims the '16 Prius will deliver 59mpg city & 59.7 hwy...
So, according to Motor Trend, a '16 Li-ion (non Eco) Prius is good for somewhere in between:
56.5-59 mpg city
53.4-59.7 mpg hwy

For reference, Motor Trend's "Real MPG" used to list the Gen 3 Prius' at: 54.7mpg city, 47.9mpg hwy

Again, YMMV. Enjoy!

 

Just drove mine home tonight in CT. Mid 40s. Over about 40 miles, almost 60 mpg reported. It's amazing.

 

very good mpgs, especially with temperature that cool. Congratulation on your new ride.

 

Around 4.5L/100km with temperatures under 0C and with elevation difference, is excellent news. Thanks for sharing.
On my Gen3 I usually get a full L more at temperatures below 0C/32F - i.e. 5.4L/100km (43mpg) (albeit in city traffic, with some elevation difference) - which is coincidentally my lifetime average (see Spritmonitor) on 98.000km/61.000mi, that includes about 70% city traffic, and 30% highway at 130km/h (80mph) or more (real GPS speed, not nonsense 10%+ reported by the very inaccurate speedometer) and not on flat land.
These numbers are making the whole thing more and more interesting.

 

congrats! keep us posted!

 

Took a trip to Vegas this week (500 miles round trip). 51.5 MPG overall. Not as good as I had hoped but the conditions weren't great either. Tires were set to the factory recommended pressures. Morning temp was 25 degrees when we left, and never got above 50 the entire trip. I used the cruise control the entire way, mostly 75 MPH and had a 12-15 MPH direct headwind most of the way also. Coming back we fought a bit of a crosswind and outside temps were about the same. Along with the two of us and the suitcase, we also picked up four bags of pellets for our stove so there was an extra 160 pounds in the back. The last time we went, back in December, we drove the 05 got just over 47 MPG for the entire trip and conditions were better as there was no wind to deal with.

 

Hey that's good considering. Do *try* (hypermile, coast, etc...)? Or is it 51.5 MPG not trying?
