Proposed standards are expected to be the same Washington and automakers agreed to last summer

The White House, California, and major automakers have came to an agreement on proposed economy standards that will see the requirements ultimately nearly double fleet wide fuel economy to 54.5 mpg by 2025.
People against the plan in the auto industry and Washington have argued that the 54.5 mpg goal will mean additional money added to the price of each vehicle and the loss of jobs in the auto industry due to reduced sales. Some estimates from Washington peg the cost to the automotive industry to meet the proposed standards at as much as $100 billion.
The proposed 54.5 mpg standard would save customers $6,600 in lifetime fuel costs for a 2025 model year vehicle. The Department of Transportation (DOT) and Environmental Protection Agency (EPA), however, rightly point out that the actual savings is closer to $4,400 when you take into account the additional cost of the technology needed (as reflected by the sticker price of the car) to make cars reach such lofty mileage numbers.
"These unprecedented standards are a remarkable leap forward in improving fuel efficiency. We expect this program will not only save consumers money, it will ensure automakers have the regulatory certainty they need to make key decisions that create jobs and invest in the future," said U.S. Transportation Secretary Ray LaHood. "We are pleased that we've been able to work with the auto industry, the states, and leaders in the environmental and labor communities to move toward even tougher standards for the second phase of the President's national program to improve fuel economy and reduce pollution."
"This is an important addition to the landmark clean cars program that President Obama initiated to establish fuel economy standards more than two years ago," added EPA Administrator Lisa P. Jackson. "The progress we made with the help of the auto industry, the environmental community, consumer groups and others will be expanded upon in the years to come -- benefitting the health, the environment and the economy for the American people."
A letter sent to President Obama this week from 100 House Democrats praised the new standards writing, "[The new efficiency standards] increase our national and economic security in an unprecedented way by dramatically decreasing our dependence on foreign sources of petroleum." 

The following are areas targeted for improving fuel efficiency across the board:
  • More efficient gasoline engines
  • Greater availability of diesel engines for passenger cars
  • Advanced transmissions
  • Improvements in vehicle aerodynamics
  • Reduced vehicle weight thanks to the use of aluminum and composites
  • Low rolling resistance tires
  • Improved air conditioning systems
  • More efficient vehicle accessories
The rules offered up today are not final; there is still a period for the industry and consumers to make comment on the rules. Administration official in Washington said recently that cars would have to average 62 mpg and light trucks 44 mpg to meet the economy standards of 54.5 mpg by 2025. The EPA estimates that real world driving would see 39 mpg.
Some in Washington have already argued that the new fuel economy proposal will legislate out of existence the cars on the market today selling for under $15,000. Obama and his administration still claim that the new standards will save consumers $1.7 trillion in fuel over the life of the vehicles on the road. That figure is contested and some fear that automakers will be forced to build vehicles consumers aren't interested in to meet the economy standards.

I took my 99 Honda Civic that normally gets 39/40 mpg...

You only get 1 mpg better on the highway than in city driving?

quote: a place that sells gas without the ethanol and nursed it, I got 55 mpg.

You're claiming you went from 40 MPG to 55 MPG by using pure gasoline. Right? That's a staggering 37.5% increase in fuel economy. Since ethanol has approximately 75% the energy content as gasoline, E10 (which is the maximum currently legal to sell in pump gas) has approximately 97.5% the energy content as gasoline.

If you're numbers are correct, ethanol would have a negative energy content of about -70,000 BTU.

More likely is that your MPG numbers are more of a failure than the environmental measures you're referring to.

Last summer I drove a 2005 Silverado 4x4 with the 4.8L V8 from BC, down to the I90 and then east to Iowa. As we moved further and further east our mileage moved lower and lower. We went from no ethanol to only ethanol blends throughout the mid-US. Our mileage went from 32mpg down to 18mpg. I90 is really straight, and some of the difference could be attributed to the elevation change, but there is no way it's all elevation, ethanol had a big impact and this was just the ~10% ethanol, not E85 or anything. We noticed improvements in mileage when we headed back west and got out of the corn belt even though by that time we were in Montana and now climbing mountains rather than coasting down them. Had we been using the ethanol crapoline we probably would have be down in the single digit economy range. But through the mountains we stuck around 18-20.
