Ok so ive had my Prius for about a month now every gas tank and been between 45-47mpg. I thought since it was new and after the "break in period" it would start to increase. I'm reading in this thread that some 2011 are already getting in the 50s. Car has 2k miles now. I think ill adjust my tire pressure.

Starting to get it, the Prius drive style. My (new) 2011 Prius II purchased the end of May a bit over 2,500 miles now. This last tank came in at; 54.2 Computer MPG 51.4 MPG at the Pump This was about over (about) 475 miles mixed city/highway my normal daily commute is 17 miles each way. This run is 3/4 freeway A/C whenever it's hot, and my normal errands although nice weather often see me on my Scooter for hops to the store, or my Motorcycle to waste gas and "bomb" the backroads. I don't drive to just get the best milage, although I'm looking to do "well" in the Prius, best tank so far and puts my cars "lifetime" milage per the "computer" read at about 50.5 mpg's so seems pretty groovy. Don't think I'm a 60 MPG type of driver but staying in a solid 50 is very cool, I did well with my 2007 Civic, still, that vehicle was at the pump every week and now I make 2 weeks easy before I have to hit the go juice--
Mr Mov'n, clearly I'm no expert, seemed in the beginning my milage was around that 47 mpg and I was reading all these 60 (mpg) club members leaving me in the proverbial dust? They say tire pressure is important so yes, check that. Terrain is an unavoidable factor and being a "Frisco" kid while I can't say for sure, seems to be a black fly in your Chardonnay. For me I think I'm starting to get the whole "pulse n' glide" without thinking about it. Accelerating into the crest of a hill then gliding with a bit of electric boost on the back side to add some gain. I also punch up "all" electric when I get into my home neighborhood for an easy 0.5 miles (a better safer driver) and again, to electric for the "traffic jam" syndrome to treat my "road rage" and helps makes me more a mellow fellow. However, now I also "roll stop signs" (becoming a new danger on the road) all for the sake that "extra mile" braggin' right. :rockon: Seems as if I have crossed to a solid 50+ mpg without being a complete "Old Codger" which is not too bad for an old codger. Mind you, I maintain two motorcycles to satisfy my lust both of which are in the plus 50 club. Seems a reasonable compromise as I find I done crossed over to 50+ too. :focus: REMEMBER your milage may vary......... :cheer2: however, driving 500 miles then getting a fill-up with less than 10 gallons, seems a MasterCard moment.
I started at 3130 PSI, AL80, max depth was 45', fresh water, drift dive. After 55 minutes had 955 PSI, just over 700 back on the boat after practicing the 10 min safety stop at 10'. Remember, YMMV
Rolling stop signs won't get you to 60mpg. I'm one of those guys at 60+ and I NEVER roll stop signs. I just glide up to them, stop, and then start off easy so the ICE doesn't light up. Lots of people do it around here, though, but I don't get the impression that their motive is saving gas. P.S. Just sold my motorcycle. Hadn't ridden it in ages, having too much fun in the Insight and the Prius.
Besides both you and your car now being broken in, I think the main component of your recent mpg gains is ideal weather; not too hot thus a lot of a/c use, not too cold so the ICE is having to run more frequently/longer to stay warm but juuuuust right. For me in the deep south, those conditions come in the winter.
It's pretty easy to get 50s or 60s per tank in the summer time if the roads are flat or slightly hilly with little or no traffic. With hypermiling under the special conditions (100% gas being one of the more very helpful factors) one can can sometimes push the Prius into 70s per tank. If you are driving continuously uphill for a long distance the optimum power level for a 2010 Toyota Prius ICE is approximately from 1240 RPM to 1500 RPM ( or from .80 GPH to 1.25 GPH if you have a ScangaugeII ) which more often than not is under the ECO capsule label up to 3/4 of the way on the ECO bar on the HSI indicator. The main computer will adjust in real time the ICE and MG1/MG2 contributions to the CVT as the car goes uphill depending on the speed, torque/power, and HV Battery SoC. In general, speeding up before going uphill and then allowing the speed to drop before you reach the top of the hill will helps keep the Prius MPG higher. When there is a long steep enough downhill stretches, you can take your foot off the accelerator and and let the gravitational forces recharge the Prius HV batteries as it goes downhill. When the HV batteries are full and the Prius is going downhill on along stretch, a hypermiler might to put the Hybrid into Neutral and allow it to coast part of the way down the hill ( this is a favorite for Gen1 Insight hypermilers with a Manual transmission ) To get the best MPGs on a Prius, one must keeping the tire pressures up. The Prius ICE warmup MPG penalty is fairly high for urban- suburban-metro area driving ( but much less so for long superhighway trips) - if you are mainly driving less than 40 mph in stop and go traffic in the winter time then you should consider blocking the air intake grills on your Prius to enhance its ability to warm up and stay warm in cold temperature.
It seems to me that the folks getting 60 -70 mpg tanks must really be pissing off other drivers. The very slow starts (to keep the ICE from turning on) would get you run over in my neck of the woods. And using pulse and glide is stressful (for me) and detracts from my being an alert defensive driver. I drive my Prius pretty much like I drove my truck and average 50 mpg. I'm happy with that. FWIW.
My take is that if you drive a Prius with absolutely no care at all for fuel economy you will get in the 40's mpg range. If you drive in a conservative manner you will get in the 50's mpg range. If you drive like you have one gallon left and you have to go 70 miles or walk the rest of the distance you will get in the 60's mpg. alfon
I think alfon is straight on. Although depending on where you live, and the length of your trips I think low 50's is a given, high 50's is conservative driving, and anything over that you piss a lot of people off, or do most of your driving at night time with very little traffic out.
Actually 60 mpg to 70 mpg is only possible if the daily commutes are over 50 minutes/10 miles long, the driving temperatures is over 65 Fahrenheit, and the roads are smooth, and there's not too much traffic on the road. The Prius can get 64 mpg if the cruise control is set to 53 mph and its just driven non-stop for for 2 hours straight. Drive a full hybrid less than 20 minutes each way to and from work and your MPGs will only be in the 40s. The ICE initial warmup penalty is from 15mpg to 25 mpg which is difficult to overcome unless the Prius is driven over 40 minutes- 8 miles each way. If the roadway is very congested with aggressive drivers - P&G will be difficult if impossible - inorder to do P&G - a hypermiler has to find a route and a time when it is possible - searching for that route and time can be problematic and often is skipped over when people talk about P&G. In addition, hypermiling takes time - the less time you have to get from one place to another - the less hypermiling makes sense. Essentially, hypermiling techniques like P&G trades travel time for fuel efficiency. If you don't have the time then most hypermiling techniques like P&G are not going to work for you. One trick I use for a quick start from a dead stop, is I switch on EV mode and accelerate up 25 mph very quickly --- At 25 mph, the Prius will automatically switch over to the ICE, when it does as long as the ICE is burning less than 1.20 gph - the FE should still be okay. You can't do this trick too often else your SoC will drop like a rock and force the ICE to do a auto HV recharge - which causes your MPGs to drop by about 6 mph. but once in a while - it can be done if the SoC is greater than 55% :focus: As for my monthly fillup and most recent tank .... car = 2010 Toyota Prius III, Blue Ribbon/Dk Grey, tire = Yokohama Avid S33 (50 psi / 48 psi) special equipment = ICE air intake 100% blocked, ScangaugeII date= 9/29/2011, odeometer= 15816 miles travelled = 727 miles gallons (Mobil E10 87oct) = 10.251 gallons cost = 3.439/gallon (cash price) calculated mpg = 70.12 mpg Temperature range = 65F to 80F Weather = 33% Rain/66% Sunny-Cloudy Daily commute = 16 miles, very hilly, congested urban like traffic 25% of the time.
530.6 miles 9.817 gallons $3.219/gallon $31.60 total 54.05 calculated mpg 55.5 computer mpg on tank. $0.0595/mile
$3.219 a gallon?! Really jealous about that number. I just filled up and the $3.759 I paid was less than many other stations along my route home. Just filled up for the second time: 393.0 miles 7.731 gallons 53.7 car computed mpg 50.83 calculated mpg 300 miles of the tank were my normal commute, 2 round trips. Weather was interesting - left home this morning at 36F and a bit of slushy snow on the windshield, left work this evening it was 69F and 39F when I got home. Windy, too (the car isn't bad in the wind at all though I definitely knew it was windy). Now I'm a very, very happy camper, it looks like I'll be able to get what I had hoped for on a regular basis.
An early storm, we usually get our first storm a little later. I was a bit surprised to see the bit of snow on the car - while it's not all that unusual to see early snow on the higher mountains (and it looked like there was a pretty dusting higher up, judging from the area's webcams), it doesn't usually venture down as low as the house until sometime in November.
