Toyota Prius Prime: Detailed Range/Efficiency Ratings – 27 Miles City, 54 MPG In Gas


Toyota Prius Prime

Toyota Prius Prime

Via the EPA’s internal database, we now have our first detailed look at the various “fuel economy” ratings for the Toyota Prius Prime.

First up is the city, highway, combined MPG figures for the Prius Prime. As you’ll notice in the image below, the Prius Prime gets 55 MPG city, 53 MPG highway and 54 MPG combined.

Ever more important to us though are the electric range ratings. Seen below, the Prius Prime’s all-electric range is 27.10 miles city, 22.82 miles highway and 25 miles combined. Of note is the “all-electric range = 0 to 25 miles (combined).”  This indicates that the gas engine does have the ability to kick in at times/under certain conditions, even when you expect to be operating in pure electric mode.

prime-2All around, the Prius Prime is far more efficient (and way more electric) than the old Prius plug-in hybrid, which got 50 MPG combined and had an all-electric range of just 11 miles or “all-electric range = 0 to 6 miles (combined).”

Decent range at least. 25 miles should cover most commuting, especially if people are able to charge at work as well as home.

Indeed.. I could probably make due with the range as a PHEV, seldom using gas. It’s the acceleration numbers which I don’t think I would be able to stand.

The EV acceleration numbers are not as bad as originally reported, but still nothing to write home about. The EV mode 0 to 60 mph acceleration was originally reported as 16 seconds. Car and Driver subsequently reported the 0 to 60 time to be 12.2 seconds in EV mode, while hybrid mode posted a 10.2 second time.

That 12.2 seconds 0-60 is pretty terrible. It’s a shame they didn’t make the electric powertrain powerful enough to at minimum match the standard Prius’ acceleration at about 10 sec 0-60.

Maybe it’s peppy at low speeds though? 0-30?

The EV range is too puny. Especially in Michigan, it will be back to the 11 miles of the PiP. They just came out with this car, and it doesn’t even match the range of the Gen1 Volt from 2010. Or the Ford Energi products.

Typical Toyota, too little, too late.

Actually it beats the Ford Energi products in both range and EV acceleration. So I’m not sure what you’re talking about.

Energi but not Volt

We see that same “too little, too late” chant regularly now. It’s the result of Toyota having successfully delivered an affordable plug-in hybrid system sooner than GM. No need for the complexity & expense of liquid cooling. Like Nissan, Toyota invested in better chemistry to prevent that need. And to make a Prius into a Prime, all that’s basically needed is a clutch, charger, and a larger battery. So, it’s easy to see lots of potential.

Toyota is a laggard.

too.. little.. too.. late..

Yeah.. if only GM could make a car that did not depresiate 60% in the first 3 years.. brag on a car cause it gets better EV range but can not even break 45 mpg when the electric is gone and doesn’t even offer power seats..

How many gas cars get better than 45mpg? And when you can drive in EV mode 95% of the time, who cares?

Also, all EVs have higher depreciation due to fast moving technology, and the tax credits.

12.2 seconds is still pretty bad. I mean, a Bolt could almost accelerate to 60 twice in that amount of time. However, I haven’t driven the Prius Prime, but I suspect it will be similar to the Ford Energi products. Basically, it has great acceleration from 0-30, decent from 30-45 and abysmal above that. So it will be fine for driving around in the city, but highway driving will be a slug.

I merged onto the 70 mph highway with the electric-heat running while in EV mode. It was no big deal. Prime handled it fine.

The belief that faster is needed comes from years of marketing to convince us, even though there’s rarely a need for maximum power.

It’s too bad other plug-ins sacrificed overall efficiency just for the sake of those few rare occasions.

I’ve never seen my mother do 0-60 in less than 10 seconds ever in my life. I just don’t think she’s ever done it. Even when she owned cars with V8 engines. It is like her right ankle just won’t bend that far or something.

The point is, there are a whole lot of slow drivers out there who just won’t even know that the car is slow with the pedal to the floor, because they just won’t ever try…

Different strokes for different folks.

I drive a Prius V, so yeah Im not going to win any drag races. But then again this slow acceleration does have to be noted; there are certain on ramps that I will try and avoid due to the lack of a merging lane and the ability to accelerate quickly without fear of being rear-ended. It’s not necessarily the fact that the majority of the time you’re not going to be stomping on the accelerator (no longer gas pedal 😉 but that you can possibly need it to help you avoid potential accidents and unsafe situations. CnD recently did a comparison with the gen2 volt that was pretty good; if I had the choice I’d definitely go with the more expensive (before and after incentives) volt

You can merge in 70 MPH highway with 50 HP VW beatle from 1960’s with people honking their horns behind you, but that means nothing. Quicker acceleration means easier merging more times.

When I had Prius, I just resigned to the fact that Prius is slow and just make do. But with SparkEV, merging in freeway with confidence is refreshing. You wouldn’t understand until you regularly drive a quicker car.

Toyota says EV mode will handle half of all home-work-home commutes. With workplace charging it’s 80%.

Of course that’s a lot less than 50% or 80% of all commuting miles, since longer trips comprise a disproportionate share, but it’s still terrific at this price point.

With charging wires on our interstates a Prime would hardly ever need gas.

I own this car and the acceleration is better than on my old 2012 Hyundai Elantra. I do not know about numbers but the car performs admirably, especially in EV mode. It is not a muscle car by any stretch of the imagination, but numbers are definitely misleading here

The worse car company imaginable. At the Toyota Prius for 27k in 2012 and 3 years later they tell me its worth 7k. Then i trade it in for a corolla and i tell them i demand gap knsurance. They promised me it would be included…that was until it got totaled 7 months later and they tell me they couldnt give me gap because the extra warrenties exceeded their payment in a loan. I” with honda now untill i get cash up for the 35k tsla.

“all-electric range = 0 to 11 miles (combined).” is the correct value for gen-1. That original 6 came from a hard-acceleration during the test, which gen-2 remains in EV mode for. The “combined” is misleading, since engine triggers (like extreme cold), won’t happen during the warm season or in states with mild winters.

The point is you’ve got an plug-in electric system that’s extremely efficient. For some perspective:

31 kWh/100 mi = 106 MPGe = 2017 Chevy Volt
30 kWh/100 mi = 114 MPGe = 2016 Nissan Leaf
30 kWh/100 mi = 116 MPGe = 2016 VW e-Golf
29 kWh/100 mi = 111 MPGe = 2017 BMW i3 PHEV
28 kWh/100 mi = 119 MPGe = 2017 Chevy Bolt
27 kWh/100 mi = 124 MPGe = 2017 BMW i3 EV
25 kWh/100 mi = 133 MPGe = 2017 Toyota Prius Prime

John – there are engine triggers even on warm days, e.g. flooring it for an uphill freeway merge or exceeding 84 mph. Congrats to Toyota for expanding the EV envelope and making a very efficient car, though.

How often does a person actually drop the pedal to the floor for an uphill highway acceleration?

It’s very rare. And if the need does arise, the engine will only run for a short time anyway. The goal of greatly reduced gas consumption in favor of using electricity is still very much achieved.

Poor acceleration is enough of an issue that a lot of people reject the Prius because of it. It’s worse than typical compacts and mid-size vehicles.

And that misses the point about the triggers. The fact that turning on defrost will cause the engine to run is terrible since it so dramatically weakens the benefit of the heat pump and the key appeal of electric mode.

That assumption about defrost need is incorrect. Driving a Prius PHV in Minnesota, I know how infrequently that is actually used. Most of the time, I simply have the heater blowing on the windshield. That’s it. More is really only required on freakishly cold days and when snow is coming down hard. I only find myself pushing the defrost button on rare occasions.

23F and heavy snow this morning. Heater set 65F and blower at 2 notches. 19-mile commute in the Prius PHV.

The regular blower from the heater was plenty.

Defrost was never needed.

“How often does a person actually drop the pedal to the floor for an uphill highway acceleration?”

Certainly NOT often for a loyal Prius fan boy who goes on every EV related website to tout his bias for Prius Prime…

Give it a rest, John. Just admit that Prius is slow but good enough for slow drivers like you and then we can just agree to disagree…

Prius are basically slow moving road blocks on every uphill merging ramp.

Having driven from Prince Rupert, BC, East to Thunder Bay, from the Alaska Panhandle to Tucson, years of driving 2, 3, & 4 lane Highways in the Mountains, Toronto to Oshkosh, Oshkosh to The West Texas Mexican Border, Toronto to Key West, and Toronto to Sudbury, as well as to Maryland, Montreal, & Ottawa, I have only ‘Floored it’ a few seldom times, even on uphill on ramps, since – as a Pilot – I learned how to fly by applying smooth pressure increases and decreases, and do the same with the Accelerator Pedal, and never had merging issues in Prius, Firefly (Gas, or 96 Volt Electric), Citation, Datson 510, RX7 with Turbo, Sprint, Mini Van, Mazda 1800, or any car I have rented, in about 40 years and maybe the 300,000+ miles driven in Canada or USA, nor in England or in Australia! 0-60 times are nice to have shorter, but high speed crashes have killed more kids and adults, than slow speed crashes, I dare say! Some people can’t adapt to rapid acceleration well, so the Prime will deliver as good as many people need, for acceleration! Not everyone needs the Balls to the Wall Acceleration my RX7… Read more »

And Hyundai Ioniq Electric 136MPGe.

The Ioniq is not for sale in the USA and won’t be until April. Then the Ioniq EV has to recharge while the Prime is still on the highway making time. The Ioniq today is Beta-ware compared real plug-in hybrids.

No, it’s not “extremely” efficient. It’s only slightly more efficient in EV mode than one of the other PEVs you cite. An “extremely efficient” EV would be something like an e-bike or an electric scooter.

And more to the point, it’s only that bit more efficient over its rather small electric range. As soon as you exceed that, as soon as it starts burning gasoline, then it’s much less energy efficient than PHEVs with a longer range!

Prius Prime= Yawn

When is the Prius gonna die already? Sheesh, it was great in it’s time, but Toyota just can’t let go of ICE. Granted, they make a huge amount off the brand recognition alone, but now with a 240 mile Bolt, I don’t see the point??

The point is that you can take it to the middle of nowhere and not worry about finding a plug.

What other ICE gets that kind of mpg?

Wish the majority of ICE were Prius.

Heck, my 2012 Prius plug-in with 10-12 miles of ranges allows me to do 33% of my driving in EV mode. Double that EV range, and I’m sure I go over 50%.

The point is with my Volt I don’t need a plug, either. But my lifetime MPG is 127- twice the Prius. Granted, the efficiency in ICE mode isn’t that of the Prius, but 99% of plug drivers use… wait for it, a PLUG. Buying an ICE so I can have the most efficient ICE isn’t the point. The goal is EV. And considering 99% of the population doesn’t buy a daily driver so they can drive it into the middle of nowhere, I’d say focus on electric.

Twice that of Prius is meaningless. We’re talking about Prime.

Your 127 MPG average will easily be matched by some… and for a much lower production cost.

Note how much less electricity Prime will use compared to Volt. The KWH/MILE rating makes a difference.

$27,100 MSRP and overnight recharge with existing ordinary 120-volt household outlets is the point.

Toyota wants to reach mainstream consumers right away. Bolt doesn’t come even remotely close to fulfilling that criteria. It depends heavily upon the tax-credit subsidy and expects owners to upgrade their garage. Those are business & consumer expenses Prius Prime doesn’t require.

As for letting go of the ICE, are you implying Volt should be abandoned in favor of Bolt? If not, what is the point of Volt?

It’s the Prius Prime which should be abandoned in favor of the Volt!

25 miles of electric range, from the company which made the first popular full hybrid car, is downright embarrassing. It doesn’t hold a candle to the new Volt’s 53 miles of EPA rated electric range.

Embarrassing? You’ve totally lost perspective. The goal is to replace traditional vehicles with plug choices.

$27,100 MSRP positions the technology to be directly competitive. Prius Prime is confirmed well in that regard, an accomplishment to be proud of.

$33,220 MSRP for Volt is what? It’s heavy dependence on tax-credit to subsidize sales and compensate for the smaller rear seating certainly isn’t a bragging point.

We want plug-in purchased by the masses. Don’t forget how much importance they place on price.

“Embarrassing? You’ve totally lost perspective. The goal is to replace traditional vehicles with plug choices.”


In your stupid cases, it is replacing another Prius or another Prius plugin. So, give it a rest and you sound like a Prius sales person…

john1701a said:

No, the goal is to eliminate burning fossil fuels for ordinary transportation, or at least reduce that as much as possible.

Your argument is based on the idea that the difference in electric ranges of different PHEVs is unimportant, whereas in reality it’s by far the most important difference. It’s not merely that you have a different opinion, it’s that your assertions are factually incorrect.

You are entitled to your opinion. But you are not entitled to your own facts. — Daniel Patrick Moynihan

Not recognizing diminishing returns is a common problem.

The need for balance was the point. No absolute was stated.

It is vital to find a cost/capacity for mainstream buyers.

What’s embarrassing is the Gen 2 Volt’s atrocious reliability history so far. Consumer Reports pegs it in the bottom 20% of new cars.

So, while I enjoy my Gen 1 Volt, the Gen 2 will not be an option for me until they bring that reliability rating up to at least average.

I don’t get this thing about the overnight recharge on 120V.

If this care were massively more efficient than I’d see it.

But since it isn’t, it gains about the same amount of range overnight as a Volt, Bolt, LEAF or whatever. If 25 miles cuts it for you you can easily put that much in a Volt overnight too. Maybe the Bolt or LEAF won’t cut it for you due to no range extender, but if the Prius Prime works for you you can have a Volt too.

So everyone knows I have a prime I just went 996 miles on one tank of gas and she’s a hundred and thirteen miles per gallon I did drive the first Prius Plug-In this car exceeds its no problem as well as the heat makes it much more efficient the car is exactly what they say I achieved almost a thousand miles on one tank of gas in one shot per day charge wise…. again tell me how you drive and use the Eco gauge I gained 450 miles on the whole tank more than Toyota unbelievable

It’s good to see automakers edging toward more all electric range in their PHEVs, although I skipped the hybrids and bought a leaf because as a second car it was enough range for me, and I didn’t want the hassle of maintaining an ICE. It’s a bridge technology just like compact fluorescent bulbs were for lighting. I’m guessing in 10 years most of the cars that aren’t all electric will be PHEV, and in 15 years every new car will be all-electric.

The point of the Prime? Condo dwellers who want great efficiency and stumble upon 110v outlets here and there.

And that’s an issue that needs fixing. Someday in the future a condo without EV charging will seem just as backwards as a condo without electricity or running water. But for now, it is a challenge.

Every plug-in sold in US is capable of 120V charging. Prime isn’t any more special in this regard.

In fact, with trunk space intrusion and only 4 seats, regular Prius is far better value for apt dwellers even if it’s bit more expensive than Prime.

Well, if you literally have no place to plug in at home or at work, then there’s probably not much point in owning a Prime, given the seating and space constraints you mention. But I bet a lot of people who live in apartments or condos could plug in at home or work.

Prius should get it’s best mpg in the city because it has the lowest hp of most any motorized vehicle, along with just being in the way, when traffic does pick up.

Being behind a prius is just annoying. Owners going for efficiency over actually driving with excessively slow acceleration from a stop, and excessively early breaking for the next stop.

Similar to being behind a big rig at a stop light. The goal is get around it before the next light.

So yes it will be very efficient, but it will also be very boring, slow, in the way, and this new model…ugly.

Junk, Lame, even the Chevy Bolt, can do 50 miles in EV mode. I live in a BIG CITY Los Angeles, I can’t even do a one way on EV with the Prime to Disneyland from downtown LA, or to some Business event in OC or Irvine in EV mode one way on that LAME RANGE. I’m trying to do everything I can to not make the oil companies richer. my commute one way from home to work is 15 miles as-the-crow-flies. so I can charge it at work which is free, but then from work to home and back to work won’t make it on one charge. LAME, LAME, I was expecting at least 40 Mile range to 50 mile range on one charge like the Chevy Volt, now it looks like my next car will be the Chevy Bolt.

Prius Prime would get more support from me if it has slightly more performance. This whole “hybrid = slow” myth was started with the insight and confirmed by Prius and has been the stigma for ANY/ALL green vehicles until Tesla broke it.

It is time to move away from the slow crappy Prius.

Sure, if you need an efficient transportation, Prius is a good choice. But don’t come here to defend its performance.

The spin of want verses need is older than hybrids. Marketing to those who are told faster is better lose touch after having heard it enough times.

Prius owners tend to be better informed, not guallable enough to just take numbers at face value.

That’s why so many sakes happen as a result of test-drives.

“Prius owners tend to be better informed…”

Well, you’re certainly doing more than your fair share of dragging the average back down. 🙄

Remember how marketing convinced people that SUVs were safer?
