Researchers from the University of Iowa Public Policy Center have developed a system for charging drivers federal taxes by the distance traveled rather than on gallons of gas purchased. The study is being conducted with 2,700 drivers from states like Maryland, Texas, Iowa and California to gauge public reactions and experiences with the system. The basis for the study is the declining tax dollars being paid for car use in the States; as fuel prices rise, cars get more efficient, and alternatives like ethanol and hybrids gain ground, our 18.4-cents-a-gallon tax on gas (which was set in 1993) remains static, thereby making it harder for The Man to get paid. Eventually, the government will have to find another way to generate tax dollars from drivers -- and researchers think this might be it. Instead of paying a constant fee on the fuel we purchase, drivers cars are equipped with a taxi-like meter, and users will be given a monthly bill for the miles that they've driven. We can only hope this is avoidable, perhaps due to the spontaneous existence of a free, plentiful, environment-friendly fuel source... or another revolution.

While we've seen everything from brilliant engineering to run-of-the-mill hacks enable vehicles to squeeze every last inch out of a tank of fuel, it looks like the Senate is taking larger strides in order to raise the MPG bar. The US Senate has reportedly passed an energy bill that would raise fuel efficiency standards to an average of 35 miles-per-gallon, create additional provisions that make it unlawful to charge "unconscionably excessive" prices for oil products, and establish new appliance and lighting efficiency standards to accelerate the use of more efficient lighting in public buildings. Lastly, there was purportedly verbiage that provided "grants, loan guarantees, and other assistance to promote research into fuel efficient vehicles." Of course, the bill still has quite a ways to go before it gets set in stone, and while upping the standard sure seems novel, a quick glance around existing lots will show that quite a few whips sold today aren't quite living up to the 22.7 mpg standard that's already in place.

In a presumed attempt to prove questionable reports about the Prius' true fuel efficiency dead wrong, a Japanese group of mileage maniacs (or nenpimania) have assembled to push their hybrids to the brink and utilize a sly combination of hackery and zen-ish ways to elicit extreme miles per gallon figures. One such enthusiast burns his gas money on special tires, cardboard surround for the engine bay (saywha?), and blocks of foam rubber that occupy the grill, and somehow manages about 100 mpg by "hacking into the Toyota's computer" and carefully manipulating the accelerator with just his large toe. One upping even him, however, is a fellow mpg freak dubbed Teddy-Girl, who has reportedly become such a master of the "pulse and glide" method of driving that she can crank out 116 miles on a single gallon of fuel. Of course, sustaining such numbers on even mild inclines is entirely unlikely, and we're fairly sure you're hearing best case scenarios with all these gaudy numbers, but until we're all cruising in purely electric whips, this doesn't sound like a half bad approach to keep those trips to the pump at a minimum.

If you've been wondering how your Honda or Acura just seems to cover ground an awful lot quicker than your previous ride without even getting you a speeding ticket, listen up. Apparently, around six million Honda / Acura owners have been wheeling around in vehicles that are clicking off miles quite a bit faster than they're actually being driven. The Society of Automotive Engineers' voluntary standard for fluctuation in an odometer "is plus or minus 4-percent," and strangely enough, the National Highway Traffic Safety Administration doesn't even regulate it. Honda claims that its units were "accurate to within 3.75-percent" on the high side, but a lawsuit against them claims that's just a bit too close for the average consumer's well-being. The automaker will be shelling out over $6 million in overcharges for leasers who were unfairly penalized for exceeding the agreed upon mileage, and will also extend the warranty mileage five-percent. Of course, Honda has since tightened up its standards (read: fixed the programming bug), purportedly "aiming for zero" in regard to future error, but if you happen to own a Honda / Acura purchased between April of 2002 and November of last year (or a select '07 Honda Fit), these benefits should be coming your way pending a district court judgment on the settlement.

Nothing, we mean nothing, says success like rollin' in a big fat Hummer eh sparky? Only thing is, you can't stand the thought of those accusatory stares from your fellow highwaymen as you lumber along sucking-up fuel. Well, we guess you never heard of the Mileage Maximizer then? Don't sweat it, 'cause two friendly Detroit, rock city Hummer dealerships have, and they'll happily sell you the $190 wonder mod while touting its 30% increase in fuel efficiency. The promotion has been so successful at selling new Hummers in fact, that these boys are now considering expanding the modification to more stores and vehicles. Sure, GM and Hummer officials don't endorse the application of the "Vortex Valve" to the vehicle's intake manifold and may not even honor warranties. And just you never mind that no one will stand by those unofficial claims of increased efficiency or that tampering with the emission controls on EPA certified vehicles is, ehem, illegal. You go right on feeling better about yourself... after all, you tried, right?
