Google.org, a For-Profit Charity
Google has set up a subsidiary, Google.org, a for-profit philanthropy with initial capital of a billion dollars. Not being organized on a tax-free basis carries both advantages and drawbacks. From the article: "Unlike most charities, this one will be for-profit, allowing it to fund start-up companies, form partnerships with venture capitalists and even lobby Congress. It will also pay taxes." One of Google.org's first projects is the development of a plug-in hybrid vehicle that achieves a mileage rating equivalent to 100 MPG.

I hope it turns out as good as it blurb makes it sound. I believe Pierre Omidyar's Omidyar Network was founded with the same/similar goals in mind.
Simpy
A common system for evaluating advanced technology vehicle energy sources (hybrids, fuel cells, etc.) uses the "GREET" model developed by Argonne National Labs. This model considers the 'well-to-wheels' efficiency, which gives the most accurate picture of how a particular fuel or energy source is used. In the end, you get a measurement of miles per equivalent gallon of gasoline, or MPEGG.

Well, to be even more complete, one could also say that traditionnal car manufacturers already have diesel cars that go under 4 l/100km (over 58 mpg). Volkwagen already sold cars that could go down to 3 l/100km (or over 78 mpg).
Ok, that's not in the US, and you still need particle filters, but still, I also think that limiting the options is a bad idea.

FYI, the Prius does not use a Lithium battery.
For long battery life, they do a lot of battery management to make the battery last the life of the car.
For starters they do not treat the battery the same way you would treat a cell phone or laptop battery. Full charge then deep discharge cycles are not done. The battery is rarely charged to 100% and almost never discharged below 50%.
There are Prius cars out there with over 250K miles and still going strong on the original battery. Do some online research on the rate of Prius battery failures. Most battery failures are not the HV traction pack but the 12V cabin battery.
Cell phones and laptops are often charged fully and run down below 50% for long battery run-time. This kills batteries. Cell phone and laptop batteries life is not expected to last more than a couple years. The Prius battery on the other hand is expected to last the life of the car. The plug in mod may change the expected battery life considerably.
The truth shall set you free!
