  • Goodyear's self-inflating tires could improve gas mileage, leave Schrader valves unsatisfied

    Reminiscent of Ghostbuster's Marshmallow Man, new Goodyear tires might just Stay-Puft on their own. The company is developing Air Maintenance Technology (AMT) tires with built-in pumps to keep themselves at the perfect pressure. The reason? Even slightly under-inflated tires can drop your mileage by 3.3 percent, costing you cash at the pump. For highway-hustling commercial trucks that's a whole lot of moola, leading the US Department of Energy's Office of Vehicle Technology to grant Goodyear $1.5 million towards self-plumping commercial tire development. For those of us who don't wear mesh hats, Goodyear is working on a consumer version in its Luxembourg lab. It's unclear exactly how they will work, but earlier implementations have a pipe that's compressed as the tire rolls, allowing air to enter the tire without bursting thanks to a pressure sensitive valve. With so much automated car technology now all we need is the kind that cleans out its own trunk and pumps its own gas. Check out the full PR after the break.

  • UK students' 1,980 MPG car scores first place in marathon race, by a 1,000 MPG margin

    A car that looks like the one above and gets the "equivalent" of 1,980 miles to the gallon (and one gallon only) is certainly impressive enough on its own, but it's all the more so when you consider that it's driven by a 14-year-old and built by his classmates (with a little assistance, of course). This particular vehicle hails from Kingdown School in Wiltshire, England, and it won the recent Mallory Park Mileage Marathon by a margin of more than 1,000 MPG over its next closest competitor. Not surprisingly, however, the students are already looking to improve things for next years' race, and say they're planning on upgrading the engine for starters. No word if they're considering an X-Prize challenge after that.

  • GM reaffirms commitment to 2010 Volt launch

    Although we haven't noticed an atypical resurgence in doubters, General Motors' Bob Lutz apparently has. The exec has come forward and stated that the 2010 timeline for its much-anticipated Chevy Volt is still valid, despite the fact that employees working on the vehicle are "becoming increasingly nervous." While speaking at the Reuters Autos Summit in Detroit, Lutz also noted that there was "a lot of skepticism within the company," but that those in leadership roles firmly believe that it "has to be done." More specifically, GM is hoping to "leapfrog anything that is done by any other competitor," and while we're delighted to hear that the commitment is still strong, three years offers up a lot of time for situations to change.[Image courtesy of WindingRoad]

  • MasterFlex's CargoBike hauls wares via hydrogen fuel cells

    Nah, MasterFlex's fresh new wheels aren't exactly made for easy lugging, but if your legs are all given out, this hydrogen fuel cell-powered bicycle won't rely on fossil fuels to get you around. Designed for easily hauling goods (or rambunctious youngsters) around town, the bike also sports a 250-watt fuel cell system that not only gives your body a rest whilst handling "inner-city logistics," but you can reportedly stroll along for 150 miles at a mind-numbingly slow 3.7-miles per hour if you're in need of fresh air. Interestingly, it seems that the power system can also be channeled to peripheral lighting sources or to "cool transported goods," which should definitely interest those looking to open a mobile drink shop in downtown Phoenix. The bikes are already being utilized in various third world nations, but the pieces are seemingly in place to get these motorized machines to areas of Europe in the very near future.[Via Wired]

  • Toyota looking to go hybrid-only by 2020?

    Be warned, you should certainly take this one with a helping or two of salt, but according to a report over at Motor Authority, Toyota's Masatami Takimoto has at least insinuated that by 2020, hybrid vehicles would account for "100-percent" of the automaker's fleet. Of course, the context of the conversation was surrounding the firm's recent report that it expected to "make as much money on hybrids as it does on conventional gasoline-powered cars by 2010," so all sorts of boasting was likely to be aimlessly floating out of higher-ups' mouths. While making such a bold claim can't be seen as entirely unrealistic, we have to wonder if purely electric whips won't have at least some presence in the mainstream automotive market (and Toyota's lineup) within the next 13 years.[Via Edmunds]

  • Prius hack utilizes Vehicle-to-Grid technology to power your crib

    For those of you Prius owners who felt the novelty of a hybrid vehicle was finally wearing off, a whole host of new hacks are starting to emerge, which should go quite a ways in expanding the utility of your gas-sipping whip. When you're not cruising around at the tune of 116 mpg, you can purportedly flip the power in reverse and actually juice up your house with your ride. A prototype system being demonstrated by California's Pacific Gas and Electric Company utilizes Vehicle-to-Grid (V2G) technology to actually send power in reverse to energize a few in-home lights, appliances, and of course, Wii exercise sessions. Potentially more interesting is the possibility to actually "sell back energy to the utility during hot afternoons when demand is highest and most costly to avoid blackouts." No word just yet on when this stuff will be rolled out en masse, but if you needed just one more reason to plunk down for a Prius, it doesn't get much better than this.[Via The Raw Feed]

  • Mileage maniacs hack Toyota's Prius for 116 mpg

    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.[Via The Raw Feed]
