So now our country is divided into an EV vs PHEV. Will this country survive?
That has most certainly been true for me.LeftieBiker said:I think the Prime will serve the EV community the same way the Prius and then the PIP did: by functioning as a 'gateway drug' to electric driving.

Nah.rmay635703 said:On the twice weekly 100ish mile trip I listed I'm running a lower energy use than said Prime on a 90 mile trip.

Something about your numbers is not adding up.rmay635703 said:I used .5553 gallons of gas
And 12kwhr from the wall to go
Over 99 miles
0.5553 x 25lbs + 12kwhr (at wall) x 1.5 = 31.88 lbs of CO2
Assuming someone's goal is to use the least amount of gas possible and thus reduce emissions from same, using EPA numbers to eliminate individual variation (as always YMMV, and some will do a lot better or worse, which applies to BOTH cars), the Prime uses less gas than a 2011-2012 Volt anytime you drive it 66 miles or more between charges, assuming both cars start fully charged. Note: I use the EPA Hwy rating for the Prime for gas miles, rather than combined or city, and either EPA Hwy or what a large number of people have reported getting (forget which) for the Volt 1, as I couldn't find the EPA HWY rating for it off-hand. 40 mpg is either equal or greater than the EPA number.SageBrush said:Something about your numbers is not adding up.rmay635703 said:I used .5553 gallons of gas

12 kWh from the wall is at most 11 kWh in the battery.
If you traveled 60 miles on EV, that is 5.5 miles a kWh
The remaining 40 miles of HV using 0.55 gallons is then 72 mpg
These do not look like reproducible numbers in a Volt unless undisclosed, atypical driving and/or conditions are present.

If the question is emissions then it does not make sense to ignore emissions from electricity.GRA said:Assuming someone's goal is to use the least amount of gas possible and thus reduce emissions from same,

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_file.jsp?docid=37789&flag=1
Page 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.

I'm not seeing the numbers you quote on page 27. On page 26 it shows 43.6 mpg for a test labeled SC03, and on 28 it shows the 46.7 you mention for CD highway, but I'm not sure if that's the offical EPA highway number, as I believe they also include US06 into the mix for that and then round. I'm going to try and find the official range numbers they released - I think IEVS included them.SageBrush said:Any problem with putting the Volt in a separate thread !?
