Volkswagen Seeks To Repair Its Image By Focusing On Electric (wired.com)
An anonymous reader writes: The emissions scandal that's plagued Volkswagen over the past month will be tough to recover from. But they're trying. The company announced a number of changes they're making to their line of vehicles. First, they'll be revamping their flagship Phaeton vehicles to be all-electric. (If you live in the U.S. and haven't heard of these, don't be surprised — they aren't marketed there.) Second, they've announced their intention to install top-of-the-line environmental protection systems in their new diesel cars. (In other words, they'll actually do what they're required by law to do, but vehicle prices will jump significantly.) Their press release is difficult to decipher, given the density of buzzwords and vague promises, but they indicate a greater general focus on hybrids and electric vehicles in the future.
I'd say Volkswagon can count on the short term memory of the buying public.
Like a bad breakup, time will heal this, too.

Bullshit. They conned the entire fucking planet. Europe has far higher emission requirements than the US, and most countries require vehicles to be tested annually. Fail the test, your is rendered illegal for public roads. VW's aim was to mislead the public about the efficiency of their diesel engines, but the efficiency took a dive in clean running mode, so they switched it off only for testing conditions.
Because the EPA requirements are zealous, and makes producing a diesel vehicle unviable.
No it does not. Diesels can easily meet the emissions rules and there are plenty of vehicles that do it without cheating. VW cheated because they didn't want to install the expensive equipment necessary to make this happen such as a urea injection system. It has nothing to do with diesel technology and everything to do with profit motive. VW cheated to pad their bottom line.
The funny thing is electric cars are the real unviable vehicles, hydrogen powered vehicles are the best idea, only waste they produce from the combustion of hydrogen is water.
Umm, what? Hydrogen powered cars are clearly a non-starter at this time. Basically zero fuel infrastructure unless you use derivatives of hydrocarbons which basically ends up with the same sort of emissions problems we currently face. They've got high emissions intensity because our primary source of hydrogen is from natural gas. They also have low performance (comparatively) and poor efficiency (comparatively) with PHEVs. While conceptually hydrogen power has some attractive features, in practice it isn't superior to existing alternatives and there is no evidence to suggest that will change in the near future.
Since you think (wrongly IMO) that electric cars are "unviable", I'm not going to waste time trying to convince you otherwise but so far the evidence does not appear to be agreeing with you. Electric and hybrid electric vehicles are pretty clearly the next evolution in automobiles and that only happens if they are a viable technology.

Right. So what they're going to do is make yet another "Tesla killer" that sells to a few thousand rich people, and leave all the people that bought a Jetta in the cold. The net effect of this on overall emissions will be basically zero.
Perhaps they would be better off spending this on making a diesel hybrid PEH drivetrain that could equip 80% of the cars they sell? This is a move that takes far less development, would cost less in real dollar terms, and would *drastically* reduce overall real-world emissions.
Hydrogen has more energy per mass than gasoline.
It has more energy per unit of mass (Specific Energy) but FAR less per unit of volume (Energy Density). So unless you plan on turning it into liquid hydrogen (impractical and dangerous) or can find some alternative storage medium, it's not practical as a fuel. The chemical storage mediums we've found so far are either lab experiments or impractical for various reasons.
The future is storing hydrogen in magnesium hydride and using algae to produce hydrogen.
And your evidence for this is what exactly? You are talking about a couple of laboratory projects. Nothing that is in any danger of becoming a commercial product any time soon. Your biological solution hasn't solved the key efficiency problem plus a host of other non-trivial issues. Your storage medium is not used in an commercial product that I am aware of.
I have no principled objection to hydrogen powered vehicles but I think your optimism regarding their prospects as commercial products is unwarranted given the available evidence. If we do see commercial hydrogen powered vehicles it will not be at any kind of scale for many many years.
