Coming Back To The Prius Family

Welcome Back!

 

Be a conscious driver and become used to plug it in a s often you can to maximize your fuel economy

 

Hey.

 

Yo!

 

$2000 per year estimated...does this include electric energy costs? If not, real figures might actually be around $900 or so

 

What was the price of the used PiP? If you don't mind me asking. I know you paid $4000 out of pocket but just curious what used ones go for.

 

Depends on what you were driving and how you were driving it, but you can save a lot of money with the Prius. In my case, I drove a 2009 Toyota Corolla for mainly commuting, and it was costing me $200 more per month than I'm spending now with my PiP, for the same type of driving. That's a $2400 a year savings, and in the process, I gain more cargo room and a much nicer ride.

 

Again - energy costs? I can see $200 a month in savings for gas only...but people forget - Teslas and Leafs still cost money to charge! And in my town it's 17 cents per KWh which is roughly $3.4 / gallon of gas equivalent, around 28 cents savings per gallon So on a 10 gal fill, (and this is only if I recharge that worth) I'd save myself $2.80 cents. But I'm estimating on a 10 EV mile average and about 4 KW charge (I know that's not real world, but maybe average?)

 

Most of my mileage comes from burning gasoline. I only plug in when it's convenient, which isn't most of the time.

 

Let's see, a full charge is about 3KWh from the wall (counting charging losses) = $0.51 at your electric rates. A full charge gets you about 13 miles, which is about 1/4 gallon of gasoline. So that makes your fuel cost on electricity be equivalent to about $2.04/gallon. At least, that is what my numbers say

 

If a Tesla can do 333W/mi (which it can, better even for some Tesla owners), thats 3 miles per $0.17 of electricity. So to go 50 miles (which I'm assuming you are using by comparing with your 2010 Prius), it would cost a Tesla $2.80, which would be about $0.88 a gallon savings based on your $3.68 per gallon scenario. So to go an equivalent number of miles as a 10 gallon fill in a Prius, it would be saving $8.80 per tank. I'm not sure what W/mi a Leaf does, but I bet its better than a Tesla MS.

Your earlier comment about $2000 of gas savings turning into $900 would only happen with a crazy amount of EV miles.. at your rate of $0.17, that would pay for about 6,500kWh.. lets say the PiP gets 270W/mi (which it can, some better), that would be 24,000 miles of pure EV from the wall, per year from his home (although he said he's getting juice at work too)

A PiP's full charge is about 3kW

 

On most days, my 40-mile round-trip commute averages 56 usmpg. It's mostly at freeway speeds at 50-60 mph, with 3 traffic lights en-route. My best mileage on the commute has been 60 mpg, and some days it's as low as 49. All of these numbers are without any plugging-in.

 

Thanks for the info. I'm going to be selling my 2014 with 8k miles so I am trying to gather info right now.

 

Your electric to gasoline cost ratio is off a bit.

Let's do a quick check:
You can go about (arguably for calculation sake) 11 miles on 3kWh (or in your case, $.51). If you get nominally 50mpg on gasoline, your equivalent cost is approximately $.51 x 5 or $2.50/gal. That's a lot better than $3.40 and this is a conservative estimate (lowball EV range).

At 15 miles EV range (and assuming the same 50mpg), your equivalent cost is $.51 x 3.3 or about$1.80/gal. That comports with what I've come to see as a quick and dirty way to calculate kWh cost to gasoline: about 10x your kWh rate.

 

welcome back sushi, all the best with your pip! 2012 was a great year.
