##### Description

The 2017 Prius Prime marks Toyota’s re-entry into the plug-in car market. The Prius Prime offers 25 miles of all electric range and an additional 615 miles of hybrid range for a total range of 640 miles. The Prime features a 265 pound 8.8 kWh lithium ion battery coupled to an electric motor and a 1.8-liter 4-cylinder gas engine that generate a combined 121 horsepower (90 kW). In hybrid mode, the Prime achieves 54 miles per gallon with an 11.3 gallon gas tank; combined with the electric range, the Prime has a total MPG rating of 133 miles per gallon. The four-seater Prime is offered in three trims: Plus (starting at $27,100), Premium (starting at $28,800), and Advanced (starting at $33,100). All trims feature the same battery size, range, and performance, as well as 19.8 cubic feet of cargo space with fold-down rear seats. The Prime comes standard with quad-LED headlights and tail lights for optimal energy efficiency, a 11.6-inch HD center display info-tainment system, an optional heads-up display (HUD), and heated front seats with an optional heated steering wheel.

This looks like a slow vehicle with combined only 120 HP from whatever is under the hood. I like the Volt’s rating of the electric motor at 150 HP

How do you calculate how many KW hours were needed to fully charge a 2017 Prius Prime?

Cost of electricity to use Prius Prime – in EV mode:

Toyota says it takes 5.5 hours at charging rate of 3.3 KWatts = 17.15 KW-Hr.

At 12 cents per KWatt-Hr that’s about $2.00 per charge. This is the cost to run

a 12000 BTU high efficiency room air conditioner for 16 hours!

$2.00 for 25 miles is more than it costs to drive using the gas engine.

Don’t know where you get the figure of 3.3 KWatts for the charging rate. On standard house AC the current drawn by the stock charging adapter is 12Amps so charge wattage is only 1.44KW assuming 120VAC. That cuts your cost estimate by over half.

The 3.3 KWatt charging rate is for 240V level 2 charging which takes 2 hours. There is more than 2Kwh left in the battery when the car is done running in EV mode. So only about 6+ Kwh needs to be added. 6 Kwh * 12 cents is 72 cents for 25 miles. The Prius gets more than 50 miles on a gallon of gas ($2.00+) so 25 miles for $1.00. Cheaper to run on electricity.

Your math is wrong.

Battery capacity is 8.8kWhr, multiply this by the cost of energy (i.e. 0.1518 dollars per kW) then your result is $1.34 dollars per charge. In other words, if your electric company charges 15.18c per kW and you want to fully charge the 8.8kWhr battery in the Prius Prime, then it will cost you $1.34.

I’ve heard that that there is some inefficiency involved with recharging… don’t know if its true… but if it is true then it might take more Kwh to charge a fully depleted battery than the Kwh capacity of the battery.

Our electricity rate here (Oregon coast) is $0.0735 per kwh. So we are figuring a cost per full charge of $0.60-0.70. We also have high gasoline prices! So it seems like a good deal for us because we rarely drive more than 35 miles a day; most often less than 5 miles. At the end of the first year of ownership we’ll be able to compare before and after electric utility and gasoline costs. Right now it appears it will be a huge reduction in fuel costs and about $10 per month electricity costs. Even so, operating cost isn’t the reason we bought a Prius Prime. We like green technology but don’t want to organize our lives around finding recharging stations on trips exceeding the EV range, Besides, the Prius Prime is a fun car to drive in EV mode. No lack of power when needed.

Re: cost comparison of gas & electric,

Prius window sticker states 25 KWH/100 mi. Car goes 54 mi./gal. 54% of 25 = 13.5 KWH to go distance of 1 gal. gas.

KWH cost in my area is 19 cents. 13.5 x .19 = $2.56/54 mi. range. This is approximately same cost as 1 gal of gas.

However, Plug In America’s example figures* work out to $3.08/54 mi. at $.19/KWH cost [see below].

[*15,000 mi cost = $540 @ $.12/KWH, = $855 @ $.19/KWH, = $.057/mi, = $3.08/54 miles]

So Plug In America’s cost figures work out to 20% more than Toyota’s! What gives? Any ideas?

Does the New Prius Prime provide propulsion after the battery is depleted or does it assist the battery to regenerate after depletion similar to the Chevy Volt?

The Prius Prime is a parellel hybrid system where the engine and electric motor linked to the wheels to where either one or both can drive the vehicle.

I am looking to buy Prius Prime but i am skeptical regarding my eligibility for federal credit ($4500). i live in Maryland and own a house so my taxes returns are like $1000federal and 500$ paying to the state.

question is do i still qualify for federal credit or should i go for regular prius.

appreciate your help !

The amount of the federal tax credit is based on your tax liability before your paycheck withholdings are applied. The tax credit will apply to your tax liability before your withholdings are applied. If your tax liability is at least $4502, you will get the full tax credit and whatever amount of your withholdings needed to cover your tax liability. After your tax liability is covered, you would getva refund of what is left of your withholdings for the year. If it is less, then you would get the tax credit of the amount of your tax liability and get all of your withholdings for the year back as a refund.

I am thinking about buying a Prius plug-in but curious about the plug-in requirements for charging at home. I am currently renting an in-law on a property and wondering what conversion are needed for the outlets within the standard garage set up. Thanks

You will be able to charge with a chord that comes with the Prime. The cord plugs into a regular 110 Volt outlet and will take about 5.5 hours to completely charge the battery. No special equipment to buy or needed. If you want to charge faster, you can invest in a EV charging station with a 220 Volt outlet needed to completely charge the battery in about 2.1 hours.

Where do you purchase a 220V at-home charging station and how much does it cost? Don’t you need some kind of adapter for the 110V cord that comes with the Prius prime and, if so, how much does that cost? Could this harm your car or void your warranty?

We just purchased a 2017 Prius Prime Premium and we love it. We’re retired so most of driving is within the 25 mile range of this Hybrid PlugIn. The internal calculated MPG is 199.9 mpg. I think 200 mpg may be the max for this car’s calculator. The only handycap with this PHEV is there’s NO spare tire. Has anyone developed a workaround scenario & if so where did they place the spare tire since the battery pack takes up most of rear storage. I’v also found that the Dunlop Adesaver tires that came with the car don’t track well when it’s windy out. I’m moving to Michelin Premium tires since TireTrack.com shows they have the best tracking for the cost.

One question – has any tried a Synthetic Oil in this car? My prior cars were all VW TDIs diesels so I’m very much into the European Synthetic oils like Liqui Moly LongLife III 5w30 5 Liter. My researched showed that the European Synthetics seem to be far ahead of the American Synthetics like Castrol Edge. I’m curious if anyone else is using a Synthetic in their Prius Prime?

We’ve had our Prius less than a month and driven 600 miles mostly beyond EV range. So the combined mpg is only 66. Now our trips will be within EV range starting on a fully charged battery. One trip per week will exceed the EV range by just 5 miles; longer trips only every few months. The combined mpg is climbing rapidly. I imagine after a year of this driving habit our combined mpg will exceed 150 mpg. Our electric rate is $0.0735 per Kwh so driving our Prius will be very economical.

Actually this is a question: Has there been any thought to making the Rav-4 a PHEV? We currently own a Venza. My wife loves this car, but we have discussed and decided our next car would be a PHEV. Wife is a big fan of Venza sized Crossover vehicles. Originally we were going to purchase a Rav-4 and we tested both the Venza and the Rav-4. The Venza won that battle and haven’t been able to pry it from her hands since. The Rav-4 in a PHEV format would be a great addition to our family. Just throwing in my two cents…

Hi John, Have you considered the all-electric Kia Soul EV? It feels very mini SUV like, gets 93 miles per charge, and is lots of fun to drive. Also, before the end of the year, the Kia Niro plug-in hybrid crossover will arrive in California, with 25 all-electric miles. We’re holding out for that as our second car. We’ve had three Priuses, including a plug-in, but none were as quiet and refined as our Kia Soul EV.

The Prius Prime is superior to the first generation Prius PHEV. It operates like an all EV when the battery is charged. It can go up to 84 mph in all EV. It have achieved 37 EV miles on my Prime per charge. I currently have 6300 miles on mine since December 3rd and have 475 miles to empty on my 2nd tank of gas. I have driven 900 miles a month without using any gas. I have 3400 miles driven on my second tank of gas so far from when i filled up on February 26th. I got the Advanced model with all the bells and whistles. Best car i have ever owned! Love it!

The only options that Toyota has or have offered for the Rav 4 are the 2012 to 2014 Rav 4 EV or 2016 and up Rav 4 Hybrid. It is a shame that Toyota currently only offers the Prius Prime as the only plugin vehicle.
