calculation details of Volt's 230mpg city estimate

I am NOT saying that H2 will always be produced with natural gas. I am saying that companies like GM are promoting it because at present it would create a market for natural gas.

Furthermore, fuel cells are so expensive, even after a decade of intensive research, that nobody could afford one. And please do not accuse me of promoting gasoline. Battery electric cars are a much better fit for sustainably-produced electricity than are fuel cell cars.

The technology for fast charging IS here now. Fast-charging stations exist! Tesla has installed fast-charging stations in its region, and Nissan is installing fast-charging stations in its test markets for the Leaf. We do not yet have extensive infrastructure in place. In five to ten years we could have fast-charging stations on all our highways if we chose to. Meanwhile, fuel-cell cars will still cost between one million and ten million dollars each!

 

Tell me why you think GM is any more connected to fossil fuel companies than say toyota, ford or nissan? Not urban legend crap, real facts.

 

Overlapping boards of directors and reciprocal share ownership. All the Big Three. None of the Japanese.

 

Malorn seems to have disappeared from this thread. Who wudda thunk ?

 

Is that a loss? NOT

 

GM is in the business of 'managing' information. As they have told us umpteen times, "it is about perception."

Unless you drive a Prius. Then you know what your mpg is, and you are corrupted.

 

The contract worked. :eyebrows:

I like to read more about that. Any good links?

 

so the math is to be ignored? Why again waste energy to create energy, store energy, then put it to use? short answer is this: show me where hydrogen is a better deal than simply storing electricity in a battery. I mean...h2 is an energy storage medium that has many steps and parts...ALL i've read and I'm sure not saying I'm an expert...ALL i've read says h2 is a stupid way to utilize our electricity for cars. what's it take to compress that h2 in a tank? what's it take to get h2 OUT of substances (such as water or natural gas)? it all adds up to more than if a battery is used to store electricity. Simple laws of physics and all that.

that's all. use less, pollute less. so using more energy to make energy is good? not in my world.

PS I'd welcome more info on the efficiency of h2. i will continue to look myself...

 

Thanks, best post of the month! rofl

 

Iceland is unique, due to it's geothermal energy mix. Do not extrapolate what they do to anywhere else.

 

Nice. So a Prius uses 383 gallons. A series hybrid would have used 172 gallons.

I see in the standardized 15K miles, you could have used a BEV like Leaf, 350 days. Only on 15 or so days you'd have done more than 85 miles. This is why I think it makes perfect sense for a multi-car family to replace one of the ICE cars with a BEV.

 

Interesting... For you, PHV Prius would use only 84 gallons of gas more per year than the Volt.

 

Burning fossil fuels for heat is very efficient. Unless you get electricity from renewables, I doubt you will save much emission.

 

PHV Prius has already been certified with Enhanced AT-PZEV. I think Stage1 warm up period can be minimized, if not eliminated.

Can you take a picture of the PHV Prius catalyst converter? I want to compare it to a standard Prius' to see if there is extra heat shield.

PHV Prius should be able to supply cabin heat without taking away heat from the coolant since the heat will be supplied by the heat-pump. You should be able to drive further with the gas engine off for sure.

The Volt is able to get 39.9 EV miles in 40 deg F outside temp. The entire trip was 44 miles and it got impressive 338 MPG! There is no indication if the heater was turned on or not.

Further analysis shows that CS mode gave only 31.5 MPG (4.1 miles / 0.13 gallon) and the Lifetime average is 60.5 MPG!

Nice data and graph. Thanks for collecting and reporting.
