Mach E AWD Equivalent MPG of ICE Cars in New England based on Gas Cost.

[Nklem]

I evaluate my EVs this way. It know not many others do, but to me it paints a great picture of the benefit of EVs based on Home Level 2 Charging.

I calculated the equivalent MPG of an ICE car to match the Mach E for my home electrical rate and the EA rate and figured I would share it.

I am sure folks are wondering what the Mach E costs to drive (Fuel only) compared to ICE (Gas cars) cars.

My home Electricity rate is $0.234 per kWh in Maine. The EA DCFC rate is $0.43/kWh

I assumed winter, 2.2 M/kWh, EPA Spec 3.1 M/kWh, and best summer of 3.7 M/kWh

BTW, to use the chart,
If Gas is $5.00 per gallon, and you pay $0.15/kWh for home electricity, a Gas Car would have to get 73 MPG Winter or 123 MPG summer to equal the cost of driving a Mach E based on charging at home.

wow, your electricity is expensive in ME ! $.23/kWhr retail for residential ?!

we have a tiered rate in NM, not time of use... Most of the state is served by PNM which has retail rate of $.09/kWhr for first 450, then about $.11 for 450-900, and $.13 above that. Going Solar however is even better; a 'premium' system with true 25 yr warranty enables the net cost to be amortized over the warranty, and drops the cost to about $.05/kWhr produced under warranty in most cases for Residential solar.

so.... I find it interesting to break it down to cost per mile. If you consider only fuel cost.....
- avg actual $/mi for me, in NM with Solar, is about : $.05/kWhr / 3 mi/kWhr = $0.0166 / mile
- similar size ICE vehicle might get ... 20 mpg ? at current price $4.03/g for regular...
thats 4.03/20 = $.2015 / mi

soooo.... 2 cents/ mile for electricity in my case, versus closer to 20 cents/ mile for similar ICE vehicle
... but the fuel cost is only part of the story

if you really want to be 'fair', you might want to consider the battery pack itself to be a 'consumable' part of the BEV fuel system. Lets say it costs $28k to replace after 100k miles.... that adds $.28/mile to the BEV side.... But by extension you'd probably have to include 100k miles worth of oil changes, maintenance, and 'average' repair costs for an ICE vehicle... maybe around $10k/100k miles; or, adding around $.10/mile for ICE related maintenance and repairs.

Of course paying for EA Pass+ gets you $.31/kWh and a breakeven of less than a day's normal travel.

Yes, that's expensive electricity!

Yup. Shutting down Nuclear plants, removing hydroelectric dams and super high natural gas costs... It is so saaad! New England and California are the highest rates in the Country. They also deregulated our power in the 90's which makes T & D and Power separate profit centers AND utilities cannot own generation. A big mistake from our wonderful lawmakers. Congrats on the cheap power. RI has off shore Wind. The cost bases of that (net cost of the power is around $0.20/kWH without T & D.) Government needs to stay out of the Power Business and let utilities figure what is best for the customer.

That's exactly what the deregulation did. You can't have it both ways. Of course, with deregulation the utilities figured out what was best for their profits.

I'm not sure I understand how to read your chart. What is the result?

If I understand it correctly (and I've done these calculation myself), the table lists the breakeven MPG an ICE car would need to get given gas costs (the left side) and electricity rates (the top) and actual miles/kWh achieved (the 3 columns under each electricity rate).

The choice of starting gas at $4.25/gal indicates that he built this within the last week. I started mine at $2.50 and stopped at $4.50/gal.

Side note: when people ask me about charging costs, I find the easiest comparison is $/100 miles. Maybe I'll build and share that table later.

My very old Lexus gets about 3 miles per dollar.
My electric Mustang gets about 12 miles per dollar.

12 is better.

Interesting that 3rd Party Fast charging, Newer ICE vehicles have the advantage until $5.50. Home charging, except for you in winter, no contest.

You left $2.00 gas off your chart. And $2.50, $3.00, $3.50, and $4.00.

It's spiking right now but that's surely temporary.

Electricity in my part of Massachusetts is around $0.28/kwh 24/7 with no discounts available, distribution costs are about half of that. I can't believe how cheap electricity is in other parts of the country.

I just do it as $ per mile. Never really cared for the 100 mile (or 100 km) scale-up. I just fine it simpler to go straight to the base unit.

exactly.....
and depending on what YOUR local cost for electricity is, or amortized cost if you have Solar, you can boil that down to $/mi easily.... then reverse to calculate the 'break-even' price of gas assuming some aprox mpg for a similar size SUV... which I would peg at maybe 20-22 mpg for a AWD 'performance' SUV

Yeah, it would be helpful to compare at all likely fuel prices.

But either way, it’s waaaaaay more helpful than however they figure MPGe.
