Do you mean Chevy "Volt"? I think VW and BMW announced last year a joint project to build charging stations along the east coast.They are going to have to come up with something a lot better than the current e-Golf - something comparable to the Chevrolet Bolt, for example, if they want to sell much more than 6 of them.
If one outcome involves installing a huge number of SAE Combo Level 3 public charging stations, that would help.
That was in the Article too. VW would pay a big chunk for changing infrastructure.... If one outcome involves installing a huge number of SAE Combo Level 3 public charging stations, that would help.
Might take a look here, post 693. Makes going electric interesting considering cradle to grave rather than just driving.

Yup . . . on golf courses . . . I find no value or desire elsewhere . . .I see this as a way out for the dieselgate mess,for VW.
And yes there is a need for electric powered Volkswagens.
I'm probably missing something, so I'll ask... what "fuel" (green bar) is involved in the solar charging of an e-Golf? Does this take into account the production of the solar panels or something?What's ironic if this is true is that corresponding electric vehicles would likely produce more life-cycle emission damage costs in most grids in the U.S. than the "cheating" TDIs. Graphical comparison of "cheating" Golf TDI (using "urban" emission profile of the 2013 Passat TDI in ICCT/WVU tests), Golf 1.8T and e-Golf, using GREET and EPA emission damage costs.
The German Papers report, that's the way VW will need to go. It's not speculative at all.VW not commenting, EPA not commenting. This is therefore speculative. As with all speculation that is outside of the Dieselgate threadzilla, I'm inclined to either lock this or combine it with Threadzilla - where this has already been mentioned.
Yes, it takes into account the production of the PV solar panels. Apparently, it's quite energy intensive to produce those panels per unit of electricity produced (at least according to the GREET model).I'm probably missing something, so I'll ask... what "fuel" (green bar) is involved in the solar charging of an e-Golf? Does this take into account the production of the solar panels or something?
Nevertheless, just because EVs produce (essentially) no direct vehicle emissions, there are significant emissions produced from manufacturing of the vehicle, and producing the "fuel".I hate when people make the argument that EVs are not as efficient because they simply transfer the source of emissions from the vehicle to the electricity source.
While it is true that in a state that uses primarily coal for electricity generation like Arizona for example. In a state like Washington, where the majority of electricity is hydroelectric then you can't make the same argument.
California, which has pushed EV adoption the hardest, only has 0.5% of its energy generated by coal. Of the rest 61% is generated using natural gas, which although still a fossil fuel is much more efficient than burning oil, gasoline or diesel. All the rest of California's electricity is generated using non-fossil fuel sources.
This is not to say that EVs are 100% emissions free or that they aren't without their own environmental consequences (Li mining anyone?) but it is a straw man argument to use the grid as a whipping boy for why EVs don't work.
Solar isn't the only emissions free source of power and not all fossil fuel sources are as dirty as coal.
Sorry for the rant it just irks me when it appears that it is assumed that our only sources of energy are either dirty coal or solar.
Anyway back to the discussion of possible VW EVs
I was not trying to imply that I dispute your calculations. Only that it irks me when a simplistic blanket measurement like (average US mix) is used when there is high variability depending on which state one lives in. As your improved figure above shows it is not a black and white issue there is a lot of grey. I like that figure BTW, nice job.Nevertheless, just because EVs produce (essentially) no direct vehicle emissions, there are significant emissions produced from manufacturing of the vehicle, and producing the "fuel".
The National Academy of Sciences produced a 2009 report that concluded essentially the same thing ("Hidden Costs Of Energy: Unpriced Consequences Of Energy Production And Use" - http://www8.nationalacademies.org/onpinews/newsitem.aspx?RecordID=12794). Here is a graphic from that report on its projected non-GHG emission damages for 2030 model year cars...
Based on the latest version of the GREET model (GREET_2015, available at https://greet.es.anl.gov/) and emission damage costs per EPA itself ("Draft Regulatory Impact Analysis: Proposed Rulemaking for 2017-2025 Light-Duty Vehicle Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards"; Table 7.1-6.4-1, page 7-2), the following are damage costs from various vehicle technologies and fuels currently available...
You're welcome to check my calculations (there's certainly a possibility of math errors in those calculations), but since the relative damages are reasonably close to what NAS calculated, it should be close hopefully.
I also agree that solar isn't the only source of renewable electricity, and it appears hydro power is "cleaner" than solar. It also should be noted that the "U.S. mix" for electricity is based on the latest info from EIA (first 10 months of 2015 when NG nearly equaled coal in electricity production (http://www.eia.gov/totalenergy/data/monthly/pdf/mer.pdf , Table 7.2a).
...and I still stand by my statement that one battery pack will produce more pollution overall than any diesel (IDI, DI, Common Rail...) ever. Add this to the tons of CO2 used to produce most of the electricity (because we're so afraid of The China Crisis) and you have a net loss.VW to redeem itself with electric cars?
Almost as stupid (in the corporate sense) as the early '80s GM diesels where they tried to retrofit a 350 (5.7L) block with diesel components.I should also point out that I think diesels make much more sense as a low emission passenger car here in North American than hybrids or EVs. That said I worry that what VW did may not make it an option as we go forward.
