Any problem with putting the Volt in a separate thread !?

You have an algebraic error.

In addition, your highway assumptions are wrong. Here is the correct data for the 2017 volt

https://iaspub.epa.gov/otaqpub/display_ ... 789&flag=1Page 27 is the Highway EV

46.7 miles using 16.76 kWh from the wall on L2

Page 22 is Highway gasoline

40.8 mpg*

So the correct calc for your break-even petroleum use is

25+53x = 46.7 + 40.8x

12.2x = 21.7

x = 1.778688525

miles = 25+53*1.778688525 = 119.27

**However** ...

An additional 10.46 kWh is consumed by the Volt compared to the Prime in those 119 miles

A prime can travel 25*10.46/6.3 = 41.5 EV miles on those kwh so the correct calc after adjustment for equal kWh use would be

(25+41.5) +53x = 46.7 +40.8x

12.2x = -19.8

The conclusion should be obvious ... and in fact mirrors the differences between the cars in MPGe, as expected.

**Just for fun**Let's say I didn't hate GM, and would have considered a Volt for my 90 mile commute

Volt:

46.7 miles in EV using 16.76 kwh, then 43.3 miles using gasoline at 40.8 mpg so 1.06 gallons

Prime:

66.5 miles in EV using the same 16.7 kWh, then 23.5 miles at 53 mpg so 0.4434 gallons

Or if we ignore the discrepant electricity consumption, the Prime consumes 65/53 = 1.226 gallons

See the issue ? The Volt is only competitive with the Prime if electricity consumption is ignored ... which is retarded.
