Honda leads the EV efficiency pack

Honda is bragging that his new 2013 Fit EV is leading the highest ever mile per gallon equivalency rating for an electric vehicle at 118 MPGe. To put that in perspective, the other EVs on the market come close, but fall just short of that 118 MPGe rating.
 
The Ford Focus Electric has rating of 110 MPGe, while the Prius plug-in hybrid gets 95 MPGe. The Chevrolet Volt is rated for 95 MPGe, and the Mitsubishi I EV has a 115 MPGe rating.
 
Honda estimates that the annual fuel costs for operating the Fit EV will be about $500. The little car promises 100 miles per charge of driving range from the 20 kWh lithium-ion battery pack. The Fit EV has combined city/highway driving range estimated 82 miles.
 
Honda designed the car to be efficient with a highly efficient powertrain design and weight conscious engineering combined with effective aerodynamics so the Fit is able to get a longer driving range from its smaller battery pack than other electric vehicles. The smaller battery pack also means faster charging time. Honda promises the Fit EV can charge in under three hours from the low charge indicator light coming on when connected to a 240 V circuit.

 
"Just as important as the industry-leading fuel-efficiency and fast recharging time, as a Honda, the 2013 Fit EV will be an absolute kick to drive," said Steve Center, vice president of the American Honda Environmental Business Development Office.
 
Honda plans to market the Fit EV in select California in emerging markets starting this summer and then roll the vehicle out on the East Coast in 2013.

"Coal power accounts for less than 50% since 2000. Today I think its less than 40%."

That's a huge amount, hardly an example of herring.

"An EV that is 100% powered by Coal will be slightly more polluting than a Prius type Strong Hybrid. Its true. But the difference is very slight."

Not according to the analysis I read. The analysis I read made it clear that it's simply not green to get a plug-in, let alone a full EV.

In the analyses I read, EVs give rise to less pollution. The less % of coal plants in an area, the better. Spreading any one plant's pollution output over N number of appliances makes this a simple math problem that is already widely publicised. The idea of EV's merely shifting the pollution source is just a myth - they are far less polluting than a gas burning ICE.

In any event, we should be rapidly replacing coal plants. Fine, "green" types get the most positive treatment here but building modern nuclear plants where the risk of a meltdown is basically zero (through modern design and the marvels of science invented after the 1950s) should also be pursued.

Yes, because most people (like you) who bring up the arguement like to take 100% numbers. If you multiplied by 50% or 40%, then it wouldn't be such misdirection.

Post a link. I am sure it's riddled with problems. A few common ones are the "100% Coal" and the "gasoline is free to make" issues.

The -very- best Strong Hybrid sold in the US gets ~50 miles per gallon of gasoline. Too bad gasoline doesn't spring from the ground.

Adding in refinary inefficieny (per Argonne National Lab. and DOE figures) it takes roughly .84 kWh of Oil to be deliered to a refinary to make a Prius go ~1 mile.

If this Honda Fit at ~3.5 miles per kWh of energy from the wall takes into account DOE estimates for transmission losses and power plant efficient, it takes roughly .9 kWh of Coal delievered to power plants to go one mile. (It takes roughly .3 kWh to travel one mile)

As of 2011, the US power grid for large utilities looks like this 42% Coal, 26% Natural Gas, 32% Nuclear, Renewables. This leads to 1 Fit EV mile requiring ~.55 kWh of Coal + Natural Gas and .1 kWh of Renewables/Nuclear.

The Fit EV would use ~35% less fossil fuels per mile that Prius and ~60% than the standard Fit.

(Now in this situation I've assumed it takes roughly the same energy to pump oil from the ground and get it to a refinary per kWh then Natural Gas/Coal. This is not really a great assumption, but insufficient data exists to do a good estimate for the entire US market for these variables)
