Nowadays the numbers are about 40% and 30% respectively.
Note my "over operating range" disclaimer. Not peak, static numbers
However, we agree that there is a 5-10% delta, with the advantage to diesel

People who own VOLTs buy a lot less gasoline, and it cost most people a lot less to drive on electricity then what their gas bill on a comparable car would cost.
The Ram Promaster van configuration pages are available now. Choose from 1500, 2500 and 3500 models. The Promaster is available as a cutaway cab, too. Prices start around $28K, with tons of options.
The base Promaster van uses Chrysler's 3.6L V6 gasoline engine and 6 speed automatic transmission. A four cylinder 3.0L diesel is available for $4000 extra. Note this is not the V6 diesel found in the Grand Cherokee and Ram 1500 pickup.
This web page has links to the configuration pages for the Promaster models.

A large percentage of the cost differential is attributable to taxes. It varies from state to state, but on average across the U.S. consumers are paying 48.8 cents per gallon for gasoline and 54.4 cents per gallon for diesel in federal, state, and local taxes. Electricity, CNG, propane, and etc. do not yet have any road taxes on them - but once electric and/or CNG vehicles reach some critical mass of noticeable usage, it will be irresistible for governments at all levels to get their insatiably greedy fingers on those too, so enjoy your temporary tax holiday while you can.

How very interesting.
Does anyone have specs on that engine? (I can't find anything)
I have to assume it's lighter than the 3.0 V6 in the GC and RAM 1500.
The Federal road taxes are the big difference. There are certainly taxes on electricity, but not those specific to road-use. I'm sure it's coming.
Still, a gallon of pure 87 octane gasoline holds the same energy as 33.7KwH of electricity, and electric motors are much more efficient at putting that power to the road, and not wasting a large percentage as heat and sound. So even if a gallon of pure gasoline (not ethanol blended) cost the same as 33.7KwH of electricity, the electric car would have a substantial advantage in costs-per-mile. An electric (or PHEV or EREV) car uses that energy more efficiently..... a Tesla S, for example, is officially rated at 36 KwH/100 miles. If 33.7 KwH equals a gallon of gasoline, that's the equivalent of 94 mpg....they call it mpge. A Chevy VOLT is officially rated at 98 mpge and a Chevy Spark at 119 mpge.
Right now, in my area, a gallon of 90% gasoline / 10% ethanol costs $3.70 per gallon. My daytime retail electricity rate is $0.0675 per KwH, so 33 KwH costs $2.23 at retail (at the meter, peak rates). Even stripped of taxes, a gallon of gasoline is more than $2.23 per gallon.
Take the cheaper energy and the more efficient application of that energy, and you have big savings. Since we were talking about the VOLT, here's the math:
In the real world, the VOLT takes a 12.8 KwH charge (including all losses) from full depletion to full charge, and that charge lasts approximately 35 miles in real world use.
Locally (peak-rate $0.0675), that 12.8 KwH 'fill' would cost $0.87
Locally (currently $3.70/gal), that $0.87 would buy 0.24 gallons of gasoline.
If it takes .24 gallons to drive 35 miles, that's 145 mpge.... in other words, a gasoline powered car would have to average 145mpg to have the same fuel costs per mile
Can you think of a 3,700 pound car with 275 lb-ft of torque that averages 145mpg? How about 1/2 that? 1/3 that? Even a diesel?
Hard to argue with your math. FWIW I'm not arguing against electric cars per se, I just think the differential between gas/diesel and electric will narrow over time, primarily because of increased taxes. But also because if everyone did buy an electric car, electricity demand would skyrocket, and electric rates would go up because we'd have to buy and burn that much more fossil fuels to generate the electricity.
Well, the VW Jetta TDI can get 1/3 of that (mine does), but it only puts out 236 ft-lbs of torque. That's still the big trade-off, efficiency and economy versus range and practicality of charging versus filling. Using the Jetta TDI again as an example, I can get more than 650 miles on a single tank of fuel. Like the cost of operating, I believe this differential will narrow too as electric cars get better range and diesels get more efficient. Obviously electric car range is going to have to increase exponentially before they make any significant market penetration.
Not arguing your larger points, but a good portion of electricity is (and/or can be) generated without using fossil fuels.
However, if we did nothing fossil fuel prices will go up too. The demand may be shrinking, but supplies are too. Or at the 'easy' supplies. We know where lots of oil is, but it's expensive to get to.
Jetta TDI's combined EPA rating is 34 mpg, and diesel fuel is more expensive than gasoline. So it's four times as expensive per mile as a VOLT using electricity.
Remember, a VOLT can travel 380 miles before needing gasoline or electricity. I don't think that's a range issue at all.
Even when operating on gasoline only (no EV) the VOLT is rated 37 mpg combined...still better than the Jetta TDI.
But remember that 85% of Americans drive less than 35 miles per day, so most days would be electric-only.
Pure electric vehicles with no back-up have their limitations, so I largely agree with your point.
snip...
A single data point only admittedly, but my 2010 Jetta TDI gets 42+ mpg around town and 49 mpg on the highway, and I don't "hypermile" it or drive it any differently than my other cars and trucks.
.......last week we finally replaced our old VW TDI with a new VW TDI. Much more torque & HP than the old car, probably a bit less fuel economy, but I bet we still top 40 MPG much of the time.
We are not building any more nuclear reactors......
