2010 MPG Stats - Post Them Here

I live in an area with drumilns and other glacial deposits in southern Ontario, Canada, and the hills can be pretty challenging if you are trying to get good mileage. I also tend to have a heavy foot on the gas anyway, so I`m quite happy with the 4.5 L/100 Km (52.2 mpg US or 62.7 mpg Imperial) that I get on average. Mixed in with this number are trips I have run completely on Power mode (to assess the difference), and I have still not seen them cause too much of a hit on mileage.

Today I had time for a hypermiling run and, despite all the hills, I did a circle route of 46.6 Kilometers (about 29 miles), and I got 2.9 L/100 Km (81.1 mpg US or 97.4 mpg Imp). In order to do this I had to stick to back roads where people wouldn't be bothered if I took the hills slowly.

I can see how you could easily get over 100 mpg if you were not dealing with this type of terrain.

 

Drove a total of 720 miles this weekend. On highway at speeds of 75-82 plus a tad of city driving I averaged about 47.5 mpg. Not too bad I guess.

What has helped me get to the 50 milestone has been the cooler weather... using the AC is another obstacle for good mileage...
I am forecasting many more 50+ tanks in our cooler Florida winter...with no AC running...
:cheer2:

 

My current consumption in the signature.

 

I have 3700 miles on my model III 2010 with Solar Roof. Got it in August and most miles were driven in very hot weather. So far I've gotten 53.4 mpg, my calculation. Highest tank 56.4, lowest tank 50.5mpg.

 

Just picked up my Gen 3 last Friday. Have 284 miles on it now and the display says I'm getting 52.4 MPG. Driving it in ECO mode 98% of the time but I'm not crawling up to speed either. I get off a light reasonably quickley. Driving has been probably 70% around town, 30% freeway.

I'm amazed by the car! Incredible piece of engineering.

 

The first 3rd gen Prius we delivered from our dealership was back for its first service today. Lifetime 4.4l/100km (53.5 mpg), latest trip 3.9l/100km (60.3 mpg). Average ambient temperatures for lifetime (Sep/Oct) in high 20s/early 30s C (mid to high 80s F).

 

Hello all, I'm a new 2010 Prius owner. I commute 114 miles per day in NE Ohio. Most of the drive is either 45+ MPH two lane roads with infrequent stops or freeway miles with little city congestion. Two 8-10 minute sections of city driving in my hour long commute (one way).

I'm a fast non-aggressive driver, meaning I never ride up on people or generally drive aggressively but if the road is clear and conditions are safe I'm usually doing 5 to 10 mph over. So the freeway driving for me is usually 70 to 75 mph.

All that being said, my first 3 tanks were driven 100% in my normal driving patterns with the car in ECO mode 98% of the time (would hit PWR on on-ramps occasionally but not usually) and I consistently got 50 MPG on each tank (within +/- .2 MPG per the on board).

The last 2 tanks I've tried using pulse and gliding to see what difference it would make. My drive isn't very well suited for it but doing it when and where it made sense along the route has made an overall 3 to 4 MPG difference.

I was impressed by the change but do not think, for me, a 6-8% increase when I am already at 50MPG justifies the added work to attain that. I think my monthly savings would be about 7$. For some that may be enough to justify the added "work" in driving. For me it took too much concentration away from driving to monitor the gauges and my lowering speed during gliding then what I am comfortable with.

 

Hi Bill,
Someone in another thread said that they were amazingly getting better milage when in PWR mode all the time. I'm in the city mostly, but go fairly randomly from client to client, but it does seem to have a positive effect for me. It would be interesting to see how a steady route like yours performs in that mode.

I'm 230 miles into my first tank and so far I'm getting about 52mpg with stock tire psu and 95% power mode. Pretty even mix between highway and pretty hilly city areas (anyone familiar with Manayunk in Philadelphia knows what I mean). We'll see what I can get when I inflate to 42/40 but right now I'm at about where my Gen II was in its first 5,000 miles.

 

Hi Rich. Interesting, I just refilled the tank yesterday and reset Trip A. If I remember in the morning I'll reset Trip B and ride in PWR to work and back then post my results.

Did round trip Slovenia - Munich - Slovenia on highway (speed limits up to 130kph / 80mph):
856 km, 47.4 l, 5.54 l/100km (532 mi, 12.5 gal, 42 mpg)
mfd:
856 km 5.2 l/100km av.speed 90kph (532 mi, 45.2 mpg, 56 mph)

Done on new 17" winter tyres. One way 3 adults plus 100 kg baggage.

 

I drove from Brooklyn to Philadelphia and got 59.4 mpg. Unbelievable. My gen 2 never got better than 53mpg on the same trip with the tires at 42/40. My 2010 is at whatever the stock psi is. Oh my God. Overall I'm averaging 53.5 mpg. I don't even know how to glide yet (I use the HSI, I just stink at it). Amazing. I can't wait to see what sort of mileage I'll be hitting once I break the car in.

 

Well for my route and my style of driving PWR mode was not a good choice. lol
47.5 MPG over 114 miles... worst mpg I ever got going to work and back. It was worth a try though.

Interesting side note... when I restarted the car to come home from work I had to re-engage PWR mode. When I use ECO mode it remembers the setting.

As far as I know, PWR mode just makes the gas more sensitive. Shouldn't you get the same results as normal but just having a lighter foot when not doing initial acceleration?

 

You will also need a steadier foot as the gas is also more responsive in PWR. Note that ECO mode also reduce A/C power; this will have an impact on FE.

 

Right. I think PWR is perfect for highway driving but you really need to be sensitive when on smaller roads. I find that normal mode is just not responsive enough when I need to push the car up to and maintain speeds of 60+ when the highway isn't nice and flat.

 

I'm only 100 miles into my prius. I'm in Florida, so the AC is pretty much cranked up the whole time. So far, I'm getting around 48MPG. Have to go on a long drive this weekend. Will post the results of that trip.

 

Is this your first Prius or did you own a Gen I/II previously? Either way, nice job.

 

Most of my driving was with the cruise control set. I don't think it adjusts it's sensitivity by mode so I think it went in the red more often when approaching slight grades. Thats my guess at least.

When I was actively driving I was using the HSI to drive like I normally do with acceleration up to but not in the red. I did notice the added sensitivity but if I entered the red a little I would immediately adjust.
