We have had our 2019 Prius Prime for only one week and I have a question about the expected mpg. Is the mpg you see on the dash based on an average from when you last filled up or is it a lifetime average? When the salesman said we could get up to 133 mpg I knew he was just blowing smoke. I don't think any one could get that mpg in the real world. But, I'm surprised we're not getting better mpg. The best mpg we have gotten is about 66. This includes city and highway driving. I noticed that when we are in EV mode the mpg goes up a little, but not as much as one would expect. On our last trip, the mpg at the start was about 66 and at the end of the 240 mile trip it was at 61. Most of it was highway driving as you would expect.
Welcome to PriusChat! It depends on which readout (which you cycle through via the TRIP button on your steering wheel). The odometer one will give the lifetime readout since you last reset it (either by holding TRIP to reset or by pressing “Update” on the Consumption Screen in the MFD (7” or 11.6” screen). The mpg includes both EV and HV modes. The 133mpg is mpge or the equivalent mpg for the electric mode. The HV mpg is 55mpg so if you haven’t plugged it in and you’ve been driving in hybrid mode (HV) for the past week, you’re beating the EPA numbers. As an example, here are my numbers. I’ve always plugged in where available and my engine hasn’t been on since Mar 31. In order, that’s my lifetime, Trip A (since my trip to Mount Baker), Trip B (close to lifetime) and last trip (which is empty since I just turned on the car at home)
Show off. I’m at 144 mpg for the 4500 miles I’ve put on our Prime. And I’ve only filled up 3 times. Good enough for us.
Here are my "basic" stats, these are off the top of my head without going out & looking. Lifetime average MPG = ~125 Estimated daily EV range = 27.2 When on a long distance trip, ICE MPG = ~49 MPG Rob43
Because the dealer gave them the mpg number without stating that it was the EV mpg. The hybrid mpg is 54 combined. Haha. Well I am within range of the battery capacity for my commute so that helps.
imagine buying a car that gets 54 mpg, being told it gets 133, but knowing sales people exaggerate, and still expecting much better than 66? talk about buyers remorse there are prime owners here, and have been pip owners, who really believe the number on the dash is their actual mpg compared to the gasser they were driving previously. hey, whatever works.
My 38 mile one way commute has me outside of this, but if I just did a work commute, I’d be over 200 mpg. But we take the Prime on the weekend trips, like to Napa today to pick up a wine club shipment. It’s hard for the wife to agree and not take the RX450h, but I’m a persuasive lad .
I asked the question for more information on how the mpg on the dash is calculated. There are so many variables to take into account. No buyers remorse in regard to fuel consumption.
It'll go down this weekend once I take it out on a trip (and my engine maintenance mode experiment comes to an end)
As others chimed in, the mpg displayed depends on which meter is being displayed. If it is ODO, then your mpg is a lifetime, but for TripA, TripB and icon with a car, then the mpg are corresponding to the distance for the TripA, TripB, or since the start (just for the current trip until you turn your car off). That said, the mpg numbers are just for gasoline used for that distance. Therefor, if you drove any portion of your trip using the wall charge for EV mode, the number will be inflated depending on how much of EV mode are included. 133 mpg the salesman told you is EPA rating for EV for gasoline equivalent. It is actually 133MPGe. However, you will not find any numbers showing the MPGe on PRIME.
As a general rule, I never rely on what a salesperson says about a car and I do my own research. However, during my last fill up back in April, I technically did get 215 mpg*: Record your Prime and Gas Fill-ups | Page 7 | PriusChat *Caveat: I got this by driving primarily in EV mode (my daily commute is within the ~25mile EV range). Its perfectly possible if you do significant amounts of EV driving to get the dashboard 'mpg' into the several hundred range. Though, I feel at that point mpg no longer becomes a useful measure of how efficient your vehicle is and I switched to monitoring mi/kWh.
I wish I had the 999 mpg read out on my car instead of the 199 mpg. I have just over 10,000 miles on my car and have filled up once for a total of 6.5 gallons. My gas gauge today is still showing 3/4 of a tank. Curious what the mpg reading would be since I have owned the car.
Change the units to km/h (which happens to change all the units to metric) and you can see the L/100km. Convert that into mpg. There'll be rounding errors but at least you'll be in the ballpark.
OK ... So I'm just feeling like the general wiseguy smartass that I usually am. My last mileage at fill-ups 2 Fridays ago was 68.2 mpg. On a 2005 Gen2. Yeah sure big deal. ... I've had this car since February. Bought used w/ 142,000 miles. I've put 4,000 on since. I love this car. I wish it had a sunroof. A guy on my block has one w/ a solar panel on the roof. The speakers suck when the windows are down. I still love this car.
I'd say that MPG is a meaningless metric on these vehicles. I put in $6 of gas whenever the light comes on, which is every 6-8 weeks. Last time I did that, it was 1200 miles since the last time, which is less than 2 gallons of gas here. If you do the math, that's better than 600 MPG. While it sounds great, it's utterly meaningless. I routinely get 24-28 miles per charge on the EV battery, and most days that's less than I need. So I rarely use any gas. There are a couple of places across town that I go and I'll consume most of the EV battery charge one-way. So I run on gas during most of the return trip. <shrug> It would be nice if they had a free charger there, but gas is half the cost per mile of what those chargers want, so I'm fine with the amount of gas I use. You need to come up with a strategy that maximizes your use of electric miles vs. gas miles and make that work in your favor. Everybody has different needs and driving habits, so it's very personal. And FWIW, the sales people don't understand squat about these vehicles. Most dealerships don't even bother to keep the EV batteries charged on their demo models, so nobody ever gets to test drive them in EV mode. When I bought mine, even the main battery was discharged! The car needed to be jump-started, and they ran the engine for 45 minutes just to get the main battery charged. Forget the EV battery! I was happy the regular engine would start when I drove it off the lot.
Example - I have a 20 mile drive to my daughter's house. Can't make it there and back on EV only, and I'm generally not there long enough to get much charge (an hour or so). There is a stretch of highway between here and there, and then some surface streets. So, it's EV on the surface streets, HV on the highway. With a bit of practice I can get back home with 2% battery remaining, and that's with adjustments for any charge I got there.
