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.
Smart Fortwo ED gets official EPA ratings: 94 MPG city, 79 MPG on the highway
Looks like "Team 250" is primed to add a few new members now that the EPA has revealed its official MPGe ratings for Smart's Fortwo EDs. Rated at 94 miles-per-gallon in the city and 79 on the highway, the car takes motorists 63 miles per charge -- making it slightly less able than Nissan's Leaf with its 73 mile range, 106 MPG in town, and 92 MPG on the open road. Now that the Fortwo ED has its governmental blessing, interested parties can lease one from selected dealers -- sorry folks, buying's not an option -- for a hefty $599 per-month, which seems staggeringly high compared to the $349 monthly lease rate for the larger, more capable Leaf. Perhaps the Smart squad won't be getting many new teammates after all.
EPA's letter grade automobile stickers could bring QR codes to car windows in 2013
Ever wonder how the world would still turn after MPG stickers were updated to take hybrids and EVs into consideration? Wonder no more. Purportedly, the Environmental Protection Agency is planning to decide by July's end whether it'll require "emissions grades" on all new vehicles. We're told that said stickers would resemble those shown above, complete with a QR code that could be scanned by any smartphone for more detailed information on how a grade was decided upon. As the story goes, cars would be graded from A through D, with a score of F presumably omitted for political correctness. If implemented, it wouldn't require automakers to slap these onto their rides until the 2013 model year, but as you'd expect, said car companies aren't exactly pumped about the idea. As of now, 40 percent of the vehicles on American roads would receive Cs or Ds, and Ohio's own Rep. Steven LaTourette had this to say about it: "Those who live in Planet Reality might need a minivan or SUV to haul around four kids in child and booster seats, and have room for luggage and a family dog. Thanks to the EPA, they'll be lucky to find a vehicle that gets a C." In truth, he's dead right, but there's always two sides to every story. To counter the obvious, automakers are instead backing "a more modest labeling redesign" that's not quite so jarring to consumers. Ah, the wonders of compromise.
2011 Chevy Volt gets stickered: 93MPG on battery, 37MPG on gasoline
The poster child for the electric car has just received its official EPA sticker, merely days after Nissan's Leaf received its own. The Volt has been found to have a 93MPG equivalent when running purely on batteries, while one could expect an average of 37MPG when using petrol alone. According to the EPA, the Volt will only be capable of cruising 35 miles on a full charge (here's hoping you've got a socket at your workplace, right?), but the overall range of 379 miles ain't too shabby for a car of this size. The good news here is that this sticker will enable General Motors to finally get these automobiles onto showroom floors, but the bad news is pretty obvious: 93 definitely isn't 230.
Nissan Leaf blessed with 99MPG 'equivalent' sticker, roundtable arguments ensue
Cue the pundits. Nissan's incoming Leaf has just nabbed an official EPA sticker, with a mind-melting 99MPG "equivalent" rating set to grace every single window. That'll undoubtedly catch eyes, but it's also likely to spur a huge debate on what "miles per gallon" truly means when you're throwing a battery into the mix. We actually had the pleasure of driving one ourselves late last month, but we weren't able to take off on any extended joyrides to really put MPG claims to the test. At any rate, the 99 rating breaks down to 106MPG in the city and 92MPG on the highway, but there's quite a bit of fuzzy math here that gas guzzlers aren't accustomed to considering. Nissan claims that the EPA uses a formula where 33.7 kWhs are equivalent to one gallon of gasoline energy, and that the entity also found the Leaf's efficiency to be 3.4 miles per kWh. Given that the car has a 24 kWh battery pack and can go 73 miles officially, then the EPA says it could theoretically go 99 miles if it had a 33.7 kWh pack. Still, the Leaf has to await its other label from the FTC, but it's apt to show a range of 96 to 110 miles of range. Head on past the break for the full presser.
Honda's color-changing speedometer to drive out bad driving habits
So, you've a lead foot? What of it, right? Honda's hoping to make that bad little habit vanish by using the tried and true guilt trip method, or more specifically, the Ecological Drive Assist System. For starters, the technology's ECON Mode works with the CVT and engine to "support more fuel-efficient driving." The real kicker, however, is the color-based "guidance function" -- drive like a granny, your speedo lights up green, drive a little wilder, and things get a bit blue, and if you toss fuel economy to the wind and let 'er rip, expect a full-on blue screen and the voice of God to come thundering through your sound system instructing that those horses be held. The EDAS should appear in the automaker's Insight hybrid as early as Spring 2009, though there's no word if it'll be standard equipment on the rumored S3000.
Volkswagen to produce 1-Liter car in 2010, should get over 200MPG
Although you can definitely pre-order an Aptera if you're okay with space-aged design, Volkswagen is hoping to provide another option for those looking for ridiculous MPG and a little bit of normalcy in construction. Okay, so maybe the 1-Liter isn't exactly standard fare -- with its plastic / magnesium shell and all-glass roof -- but at least it packs four whole wheels and an iconic VW badge, right? According to Motor Authority, the automaker will be producing said vehicle and pushing it to market as early as 2010, and while the minuscule engine will only take you to 75MPH, it will still seat two people -- one in front of the other, though -- and get around 235MPG. No word on a price or any of that good stuff, but we're hearing that they'll only be produced in "limited numbers" whenever they're launched.[Via EcoGeek, thanks Yossi]
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]
