    When it comes to gas mileage, Volkswagen's always had a competitive lineup of vehicles. Even still, the company wants to improve its fuel economy by 15 percent across the board come 2020. As part of said initiative, VW Group development boss Hans-Jakob Neusser announced plans to introduce the world's first 10-speed dual-clutch automatic transmission. Yes, we said 10-speed. Set to arrive in a variety of 2015 FWD and RWD models, the transmission is capable of handling up to 369 pound-feet or torque (which would be enough to power the rumored Golf R400 super-GTI seen above). Such a gearbox would save you some dollars by better optimizing the engine's RPMs, so basically, you get better gas mileage without sacrificing power. That's a win-win, right?

    When we caught a glimpse of Edison2's Very Light Car earlier this year, we were told to expect an electric version of the X-Prize winning featherweight in the near future. Well, here it is. Known as the eVLC, this "supremely aerodynamic" concept car is powered by a 10-kWh battery pack and, believe it or not, can comfortably seat four passengers. The plug-in has yet to go through the EPA's official round of mileage testing, but Edison2 claims that the eVLC is far more fuel efficient than the Nissan Leaf and believes it could even receive the highest MPGe rating ever awarded. There's still no word on when this little critter could hit the market, but you can check out Autoblog Green's gallery (at the source link below) for a more extensive tour of what Edison2 calls the "inevitable future of the automobile."

  • 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.

  • Volkswagen's XL1 concept plug-in diesel hybrid has 260MPG fuel efficiency, questionable aesthetics

    Steaming down the autobahn could be about to get a whole lot more efficient. Volkswagen has carted out its newly updated Super Efficient Vehicle concept, now dubbed the XL1, which -- after a great deal of fuzzy math, we're sure -- is rated at a 313MPG fuel efficiency and produces only 24g of CO2 per kilometer traveled. There's an electric motor and a TDI diesel engine making all the buzzing and roaring noises inside, while the overall body design is focused on making the car as light and as aerodynamic as possible. Volkswagen has achieved a 795kg curb weight by using carbon fiber, magnesium, ceramics, and aluminum to shave down any excess portliness from the XL1, while wind-tunnel testing and optimizations have resulted in a rather exemplary 0.186 drag coefficient. It's rare to see such attributes on anything outside the supercar realm, but then there's a reason why this PHEV is still only a concept. FOF. Update: Oh bother. Turns out Volkswagen's mileage claim is based on Imperial gallons, which are 1.2 times the size of the American stuff, meaning that the XL1 actually measures in at 260MPG when viewed through US glasses. Now do you see why the rest of the world has gone metric?

  • Nissan Leaf rates you against other drivers, creates a high score list for hypermilers

    Xbox Live and the Achievement system kind of reinvented the high score list, letting you compete against your friends even when you're roaming solo through a stark, barren wasteland. It looks like Nissan is doing much the same with the Leaf -- but minus the bloatflies and the supermutants. As the cars are now rolling out to eager owners we're learning more about just what its Carwings system can do and another neat trick is the "Regional Rankings" page, where one driver's driving efficiency is rated against others in the area. There are bronze, silver, and gold medals up for grabs but, if you cover the thing with speed tape and only commute downhill, you might just be awarded the platinum award. What does that get you? Why, a little picture of a trophy, of course. What were you expecting?

  • 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.

    The Week in Green is a new item from our friends at Inhabitat, recapping the week's most interesting green developments and clean tech news for us. This week Inhabitat explored the high-tech side of green building, showcasing Shigeru Ban's new design for the Pomidou-Metz art museum, and announcing the near-completion of the greenest skyscraper in the world. We also explored green building strategies ranging from super efficient LED lamps. We also saw several signs that the next generation of efficient vehicles is right around the corner - this week Chevrolet rolled out its first production Volt while Nissan announced the final pricing of its Leaf EV - a remarkably affordable $25,280. Even the hard working vehicles at FedEx are getting some much-needed relief as the company rolls out its first round of electric delivery vans. And if you're concerned about green vehicles going the distance, look no further than this student-built supercar that's able to get 2,487 MPG. This week biotech also blew our minds as researchers unveiled plant-based molecules that could create more efficient solar cells and a new type of photovoltaic frog foam that's capable of capturing carbon. Finally, sticks and stones may break bones, but scientists have figured out a way to grow new ones -- using liposuctioned human fat.

  • Toyota claims plug-in Prius averaging 65 mpg

    Not only does the impending plug-in Prius poop rainbows and chill out with unicorns, it's also doing pretty good for itself in "real world" MPG testing. Toyota claims they're hitting 65 mpg on average, 10 mpg higher than the brand new 2010 Prius "regular," and credit that fancy new lithium ion battery, which lets the car store up a lot more energy than an average hybrid. They also claim that this didn't involve any special hypermiling techniques, the drivers were instructed to drive like any other vehicle.

    Being shown at the Clean Vehicle Technology Expo in Ontario, California is Hymotion's modified Prius that can hit up to 150MPG in city areas. By adding a 175 pound battery pack to the trunk of a Prius -- which fits conveniently under the floor panel -- and charging overnight using a regular power plug, owners will be able to drive for up to 50 miles on battery power alone: that's well over the average motorist's daily journey. It'll cost $9,500 including installation, but according to one of the staff at the show, half of that could be covered by rebates as part of a new electric cars bill soon to be before Congress. Onwards we go, tip toeing towards a petrol-free future.[Thanks, I LOVE THE CAPS LOCK KEY]

  • Senate passes energy bill, hopes to up mileage standards

    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.[Via Digg, image courtesy of MPGStickers]

  • Software patch could boost MPG in gas-powered vehicles

    No doubt, we've seen more than a few sensational sounding gizmos aiming to provide (nearly) limitless power and create energy out of thin air, but a simple software patch could enable the vast majority of the world that's still stuck in gasoline-powered vehicles to get better gas mileage. John Kessels at the University of Eindhoven has partnered with Ford to develop software to improve engine performance and save "up to 2.6-percent" in terms of miles per gallon. Quite simply, the patch dynamically switches the dynamo, (which charges the car battery) on and off when it is "particularly inefficient for the engine to power it, thus improving the overall efficiency of the engine." Mr. Kessels even stated that "a simple cable and a software upgrade" was all that would be necessary to boost MPG, and thankfully it's not exclusive to Ford motors. Notably, a fuel savings closer to six-percent could likely be achieved if a "powerful starter motor" was installed to allow your engine to cut off entirely and restart quickly in between long traffic jams, but both methods have a good bit of testing to go through before being deemed non-abrasive to batteries and engine components. But hey, there's nothing a firmware upgrade can't fix, right?

  • Get more mileage from that Hummer

    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?
