The federal government has announced new rules for increased fuel economy. It's not Clark's first choice for getting the job done; that would be a sky-high gas tax to create a marketplace incentive for more efficient cars. Of course, no one seems to agree with him on that one! So that necessitates the government imposed fuel-efficiency requirements.
Over the next several years, vehicles will have to get an average of 34 miles per gallon (combined city/highway). Very few cars on our roads get this today.So how are we going to get there? Well, it won't be through the mass production of econoboxes -- even though Clark loves cheap, tiny rides!

Ultimately, auto makers will innovate with various new types of engines. At a recent European auto show, Renault-Nissan unveiled plans for no less than four different electric cars. Volkswagen will also have an electric car called the E-Up (
pictured to the left) available in 2013. And the Ford Grand C-MAX will be available in the next 18 months with a small turbo-charged engine at the heart of a scaled-down minivan-like vehicle.
We've already got clean diesels in the market. We might even see diesel hybrids. And of course gas-electric hybrids will continue to grow in popularity.
All these efforts will reduce foreign oil dependency and that's great from a national security perspective -- even if it's not being done through Clark's favored gas tax approach.
