New Car Fuel Updates

September 18th, 2018 at 09:29 am

This week is shaping up to be pretty quiet. I had a few social things I was trying to plan, but everyone is being super flakey. Working folk!

Today my plan is to nap in the morning and then will start hitting chores. I think just one or two days of that (chores) and I will start to feel a lot better. If I can feel like I am starting to move more forward than backwards...

Still figuring out new car and probably will make October 1 more of a starting point for really tracking costs.

Our electric company is in the process of shifting to different rates for peak times. We get to jump ahead to this new schedule with the electric car purchase (and will also get a discount for overnight electricity use). So of course I signed up the day we got the car.

In the end, we looked more carefully at the schedule. Winter prices are mostly going down. We will have to change our habits a little bit though and avoid 5pm - 8pm during the week. Off the top of my head, that maybe went up a cent or two (per Kwh) during winter.

Summer? Ugh. Electric rates more than doubled for 5pm-8pm. MH was just asking me if we were paying that now. Kind of told him, don't know, don't care. Have to power the car. It's just one more week until we can switch that to quick overnight charging? But he's kind of, "It's more than just the car. Laundry? Dishes?" Fair enough. So while he was asking me and I was looking something or other up on electric bill, I just decided to call. In the end, just more good luck on our part. We get to keep old/cheap summer rates through the end of this month. We switch to winter rates AND cheaper overnight rates starting when our bill closes, around October 1st.

Anyway, I put the new electricity schedule up on the fridge. Will have to be more mindful of peak times. I think that is easy enough for us to work around.

In the meantime, everything is just kind of chaos. We already drove new car 520 miles. Since Thursday 8pm. What in the heck!? We did drive 280-ish miles to/from the Bay Area. It was a 60 mile drive from the dealership. Everything else was more than usual. We probably both have mostly been driving new car. I did drive to my new work city and took MM to the animal shelter (both around 21 miles each way).

I'd say this week should be way more calm, but MH has stuff going on every night. Will see how that ends up.

Today I used 3 miles electric range to take MM to school. (It's 5 miles?) MH will be driving one round trip 6 miles, unless he gets off work early (probably) and has to go back to get kids later. He told me his free movie tonight is the movie theater in our neighborhood, so that may be another 6-ish miles. All electric for today.

Tomorrow we might be able to squeeze out all electric. We are going to the movies a little further away, but might be able to start with a full battery if we don't drain it more today.

Thursday is chaos. MH has a bit of a drive for paid medical study. I *just* got an e-mail from SF bff and I guess I never got back to her. Oops! Our plans are Thursday. She was waiting for me to reply. I will probably go visit her and then spend some time with my parents. Lots of driving. (Driving to the Bay Area twice in one week is not unusual at all for us, and where we hope to see some real fuel savings).

After Thursday, I think we might be able to keep it all electric? Through the weekend?

We have 60-ish miles of gas left in the car. I will try to remember to take note of mileage when we fill up. Dealership gave us a full tank of gas, to start.

How did weekend driving go?

Didn't get so much fuel efficiency on the long drive. MH was being such a backseat driver. Gah. It was the first time we had long enough to fully charge between trips. So we started with a full 53 mile electric range. I believe the car said 50 miles, and I wondered if we had been dumb to not see the full charge before we bought it. I kept it in electric mode during all the traffic we hit, and whenever we were on city streets. Not a lot of traffic or lights, but the range just kept going up more and more. I later read that 75 miles is pretty common/easy. I think in the end we ended up getting 57 miles, adding 7 miles for passing through a few bottlenecks on the freeway. (The braking generates more electricity).

I guess the car does easily get 50mpg (on gas) on the open freeway, but we had never particularly seen this advertised. They advertise the combined freeway/city rating of 43mpg. We did go over some hills. That was when MH was driving me nuts with his backseat driving.

I had it on gas mode on the hills (which was maybe a mistake) but it was *amazing*. It gets a little electric boost and that was actually pretty awesome. I usually drive pretty slow on the big hills, not wanting to gun the engine too much.

I think that trip ended up being closer to 42mpg on the fuel side. I think we can survive with that.



This display shows our trip stats. I finally looked up what MPGe was. Wasn't entirely sure. In the end, the way it works is that 33.7 Kwh is considered to be equivalent to one gallon of gas. So it figures the electric mpg and the fuel mpg, and combines it together (combined MPGe is on the left). This is by far *not* the most fuel efficient the car has been, but that's just how it worked out on our big trip. We did try to conserve all the electric charge for the traffic and city driving.

For reference, I believe our winter rates will be around $3 for 33.7 Kwh, or the equivalent of purchasing a gallon of gas. So the MPGe figures can be converted to fuel prices for a rough idea of what we are paying/saving. I am really going to track energy savings closely starting October 1 when it will be easier and more logical to track all of this.

Edited to add: I looked at winter (overnight) rate and it was cheaper than I remembered. $0.0819 per Kwh. That means it (will) cost us $1.12 to drive 53.2 miles, starting October 1 (winter rates). & again, we can improve on that electric mile range if we drive very efficiently and driving conditions are favorable to the electric engine. It will be interesting to see how my commute shakes out (real world MPGe). I am starting to think that we can quickly recoup the cost of installing a charger in our garage. If my "twice as long commute" only costs $1 per day. Maybe just 6 months to recoup the charger install in our garage?

Here is the beauty:
