- What does your home charging situation look like? (do you have a garage with a power outlet?)
- What speed do you drive for your commute? What percent City/Highway speeds? (I see you answered this, what speeds? 55 mph or 75 mph will make a big difference)
- Where do you live? Generally. Climate can impact operating costs, cold especially.
- Do you have a time of use rate plan for electricity? Does your power cost the same all day?
- How much does your electricity cost per kwh? Your bill might list cost per kwh, or estimate by taking your bill cost divided by your usage. For example, $100 / 1000 kwh = $0.10 per kwh.
- Do you have workplace charging (or even an exterior outlet that they allow you to use)?
The Clarity can charge over night (about 12 hours) from a standard wall outlet in the US. With custom 240 V outlet and charging station install (roughly $1,000 to $1,500 depending on install) can charge in 2.5 hours.
As an example, if you drive 45 miles each way, you leave with a fully charged car, about 100% of your driving is at 75 mph, you might get 40 miles EV range (guessing a little here, at 75 mph it will be less than EPA rating of 47 combined). At 75 mph you probably get 37 mpg average. So 50 miles gas a day and you are looking at 1 full charge and 1.35 gallons of gas. A full charge is about 14 kwh on the Clarity (it doesn't use all the 17 kwh battery, only about 12 and some charging losses). So my example, if you pay $0.10 per kwh and $2.60 for a gallon of 87 octane gas, you are looking at 14kwh*$0.10/kwh + 1.35gal*$2.60/gal = $4.91 per day.
A second example, if you average 55 mph and get 47 mile electric range and 43 mpg you are looking at 14 kwh of electricity and 1 gallon of gas = $4.00 per day. As it is, you use 3.6 gallons of gas per commute, and does the X3 require premium? So you would probably cut your costs at least in half. If you just look at a Prius or Ioniq or similar hybrid that gets 50 to 60 mpg for your commute you would probably be similarly priced to the Clarity.
If you go a Bolt EV or other battery electric (get at least 2x to 3x max range vs your daily commute, so for 90 mile commute your min range would be 180-270 mile EPA range) you are looking at around $2.50 to $3.00 for the commute at $0.10 cent per kwh electricity. Plus you save all the gas instead of maybe 1/2 to 2/3rds a PHEV or more efficient vehicle would save. As it is, if you commute 250 days a year at 3.6 gallons per commute you use about 900 gallons of gas per year for your commute.
As mentioned, you could easily save between 450 and 900 gallons of gas a year depending on choice and could cut your costs by 50-70% depending on your fuel prices, electricity prices, etc.
