The Obama administration is pushing for new U.S. fuel efficiency standards of 56.2 mpg by 2025. In May 2009 President Obama announced domestic car and light truck fuel efficiency standards of 35 mpg by 2016. Europe is expected to reach fuel efficiency of 60 mpg by 2020. This would still leave Europe considerably ahead of the U.S. in fuel efficiency for automobiles, but the gap would be much smaller. For the last several decades the U.S. has fallen sadly behind Europe and Japan in fuel efficiency. The perception of poor fuel efficiency hurt the automakers badly during periods of high fuel prices and when buyers were facing difficult economic choices. The automakers are beginning to grasp this fact. Mark Reuss, president of General Motors, commented that- "it's very challenging, but its upto us engineers to provide high value to the customer and support the environment." This is an issue that has serious national and global implications as it affects the future prices and demand for oil, emissions, and future economic growth. It would also bring the U.S. in line with Europe and Japan when it comes to fuel efficiency of automobiles. ...

How GM is seeing the value of new technologies not just for their value in commercialization but in the value in brand image. To be seen as the innovation leader does a lot for brand image and this does a lot for selling cars across a whole lineup which does't remotely use that technology. This is the case with hydrogen fueled cars and GM is now taking this challenge seriously. Refueling remains an issue but all untested technologies have to start somewhere and GM wants to be seen as an innovator from now on.

The critical exchange between oil companies and auto companies about who is at fault for the energy crisis. In one ad that ran last year, Chevron argued that "if automakers improved fuel economy across the board by just 5 mpg, we'd save over 22 billion gallons of gasoline a year." The criticism is also sparked by the high price of oil which is hurting sales of pickups and large SUV's that the automakers depend on for profits. One ad by Exxon Mobil shows a cartoon of a large SUV filling up at a gas station and hints that the problem rests with the automakers who have failed to build the kind of highly fuel efficient vehicles that are needed. The ad says that the average fuel economy of new U.S. autos has not gone up much in two decades, the small gains have been offset by the increases in the size and weight of vehicles.

Fuel efficiency rules require average fuel efficiency in the U.S. of 35 mpg by 2016. The debate is now on what to do for 2017 to 2025. New technology such as the P2 systems for hybrids already used in VW, Nissan and Hyundai vehicles makes a 20% increase in fuel efficiency possible. Large investments are being made to bring new technology to bear on increasing fuel efficiency significantly. Government agencies are looking at different scenarios by which the new fuel economy standards beyond 2017-2025 could be set between 47 mpg and 62 mpg. An additional factor is the reduction in greenhouse gas emissions- at 47 mpg the reduction would be 3%, at 62 mpg the reduction would be 6%. Another factor is how much the impact is on the cost of vehicles and reduced cost on gasoline. Here there is a wide range in the numbers for average mpg rules at 62 mpg- with EPA estimates at $2800-$3500 increase in vehicle cost and $5000 savings in fuel cost, Centre for Automotive Research estimates at $9790 increase in vehicle cost. The 62 mpg translates into "real world" actual efficiency of 45 mpg. In April 2011, 17 senators put out a letter of support for the 62 mpg proposal. There is a public value involved in this that is also significant- the reduced dependence on foreign oil means savings in defense expenditures in parts of the Middle East, and an economy that is less impacted by volatility in the price of oil. As this aspect of public value or benefits cannot be quantified easily even though they are significant, this may tend to be lost in the debate and the politics of fuel efficiency. For automakers there is significant marketing value in having a visible and strong presence in fuel efficient vehicles because of perception as forward looking- something that hurt Detroit carmakers in the last decade. During periods of gasoline prices at $5 a gallon this provides carmakers with an extra cushion of safety in securing car sales. Carmakers in one country such as the U.S. also have to worry about what carmakers in other countries such as Japan and Germany are doing- if the standards in the U.S. develop a gap compared to other countries developing advanced fuel efficiency technologies this poses significant risks because of the global nature of the automobile marketplace. See the group "Asleep at the Spigot" for more details on this. Many of these less quantifiable factors do not get the attention they deserve because they are significant from experience but not easily quantified. Throw into this the large unknown of what new technologies not yet developed lie ahead with a burst of effort by one country or another, which bring cost reductions at the same time - and the debate requires as much a good sense of what is the path offering the greatest advantages in years ahead than a pure exercize in numbers. ...

Controversy about whether bringing back a revamped Ford Explorer is a good idea. Ford's Farley thinks Americans might still consider an Explorer with high fuel economy, getting it up to 28 mpg from 15 mpg. But the evidence is that Americans have soured on SUV's. Consider that during the cash-for-clunkers program more Explorers were scrapped, and by a large margin, than any other model. Sales are down from 450,000 at one time to 52,000 today. To get buyers to look at the Explorer Ford is trying to change the looks from boxy to sleeker car-based crossover , and add high tech features. In fact it is going to be built not as an SUV, but on the same architectural base as the Taurus.

U.S. gasoline prices were below $2.06, adjusted for inflation, during 1986-2003, dropping to a low of $1.51 in 1998. U.S. gasoline prices at the pump dropped below $2.00 in Jan. 2015. Buyer behaviour responded quickly to the change for automobiles, with sport utility (SUV) sales rising to 34% market share in the U.S. in mid-Nov. 2014, according to Edmunds.com.

American manufacturers are importing more of the parts that go into each product. According to Susan Houseman, a senior economist at the W.E. Upjohn Institute in Kalamazoo, Michigan, the imported portion for these parts is up to 25% from 17%. Even the Bureau of Economic Analysis figure of the share of GDP coming from manufacturing is overstated, says Houseman. That figure was 11.2% for 2009, but is closer to 10.5% if all the imported components are included instead of being counted as domestically made. This is down from 14.2% ten years ago, and about 30% in the 1950's. There is deep concern that the manufacturing decline has weakened America. Houseman says that one cannot separate manufacturing from innovation, and she asks if America can continue to be strong in R&D with a shrunken manufacturing base. James Jordan of the Interstate Maglev project, says Maglev- which uses special magnets to levitate and propel high-speed trains- was invented in the United States. Today equipment for that technology is manufactured and used in Japan, and innovation in high speed trains is taking place in Japan and Germany. The decline in manufacturing is shockingly large. From 1979 employment in manufacturing went down by 8.1 million to 11.6 million, with the largest drop occurring in the last ten years. With it America is losing something significant- all the knowhow and skills that go into making things. Today the airplane wings for several Boeing airliners are made in Japan and shipped here. In a not too distant past these wings would have been built here, and workers with the knowhow and skills for these critical components were part of Boeing's workforce....
