EPA weakens annual fuel economy standard increase to 1.5 percent
While coverage of the ongoing coronavirus pandemic continues to dominate headlines, the Trump administration has quietly weakened the country's fuel economy standards. The National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) today announced the Safer Affordable Fuel-Efficient Vehicles Rule.

2020 Ford Explorer Hybrid delivers towing power and 500 miles per tank
If you're seeking a green SUV, the 2020 Ford Explorer Hybrid is a viable option -- as long as you don't opt for the four-wheel drive model. The EPA released fuel economy estimates for Ford's latest hybrid model which indicate that the rear-wheel drive model is 4 mpg more frugal than the non-hybrid Explorer's 2.3 liter turbo-4 engine. If you opt for all-wheel drive, the Hybrid is 2 mpg more frugal.

Volkswagen introduces 10-speed transmission for better fuel efficiency
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?

Ford hybrid software update will improve gas mileage, arrives in August
Apparently the window stickers of Ford's hybrid line didn't tell the whole story when it came to gas mileage. After a series of class-action lawsuits regarding fuel usage estimates and Consumer Reports noticing the vast disparity between what was advertised and what was possible, the blue oval company is finally paying the piper. To make it right, the Dearborn automaker is offering a free software update for C-MAX, Fusion and Lincoln MKZ models starting this August. There are a slew of fixes beyond supposedly better fuel efficiency, but perhaps the most dramatic is an increase in electric-only top speed. After the patch, the gas motor kicks in when the power plant reaches 85MPH, instead of the previous 62MPH threshold. No, your 88MPH joke won't work here, so don't even try it.

Chevy Volt EcoHub app tells drivers how little they pay to charge, goads them into staying green (video)
GM's OnStar team would really like us to stay on the electric side of the Chevy Volt's powertrain as much as possible. That's the selling point, after all. Rather than simply preach green driving and hope for the best, the division is testing a new EcoHub app that reminds Volt drivers just how miserly their plug-in hybrids can be. Qualifying owners who opt in or subscribe to OnStar have the Volt's energy usage costs compared to their home's total electricity bill, showing how much cheaper it can be to avoid the gas pump. There's more if money isn't enough of a motivator -- the app also builds in a counter that estimates how much gas Volt drivers are saving nationwide. The eco-friendly ego boost is currently limited to Android users participating in Pecan Street's smart grid project in Austin, but long-term plans have the app reaching iOS and all Volt fans eager to justify their ride.

Ford C-MAX Hybrid rated for 47MPG across the board, C-MAX Energi hits 85MPH in EV mode
The wait for the Ford C-MAX Hybrid has been a long one, and we'll still be waiting until the fall before the driving public takes a set of keys. In the meantime, there's good news from the EPA for travelers wondering just how far that hybrid MPV will go on its combined power. It should be quite the distance: the now-confirmed fuel economy rating is an even 47MPG, whether it's for putting around the city or cruising the highway. Ford is more than eager to crow about the figures giving its $25,995 ride an edge over Toyota, whose slightly more expensive Prius V peaks at 44MPG on highway stretches and dips to 40MPG in urban areas. The early victory parade is continuing with the C-MAX Energi, too -- the plug-in hybrid variant can peak at a brisk 85MPH in pure EV driving, or more than 20MPH faster than either the regular Hybrid or a Prius plug-in. Toyota does have the slightly important advantage of having a vehicle on the market. Those who have yet to commit to a hybrid family hauler, though, will be glad to know their patience could earn them some extra efficiency or speed.

Tesla Roadster 2.5 gets 119 MPGe rating from EPA, still as expensive as ever (updated)
Move over, Nissan, because there's a new MPGe king in town. Yesterday, the EPA anointed Tesla scored its Roadster 2.5 with an MPGe rating of 119, which would make it the most fuel-efficient car on the market. That places the plug-in ahead of both the Nissan Leaf (99 MPGe) and Chevy Volt (93 MPGe). According to the government-approved mock-up window sticker, Tesla's EV can last for up to 245 miles on a single, eight-hour charge, while getting the equivalent of 112 miles per gallon on the highway and 124 in the city. The original Roadster, meanwhile, received an MPGe score of 111 yesterday, with ratings of 105 on the open road and 116 in the city. Both models scored a perfect 10 for their greenhouse gas and smog emissions, though those ratings probably didn't factor in all the cash you'd have to burn to actually buy one. Update: We just heard from the EPA, which clarified that this is not their official rating for the Roadster 2.5. These numbers are Tesla's, and the window sticker itself is a mockup - not a legitimate sticker from the EPA. Still, if you'd like to see it, it's down 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.

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.

BMW makes the awesome look SIMPLE with leaning three-wheeler (video)
BMW's latest concept isn't quite as far out as some of its earlier efforts, and the company has dubbed it SIMPLE, but don't let that fool you. Joining Nissan's Land Glider in a new trend toward leaning vehicles that have motorbike-like footprints, the "Sustainable and Innovative Mobility Product for Low Energy consumption" is said to have similar seating space to a BMW 3 Series coupe. Its space fighter appearance isn't just for show either -- with a drag coefficient of 0.18 and a weight of only 992 pounds, this bad boy is capable of harnessing a small internal combustion engine and electric motor to tear up the autobahn at up to 124mph. Zero to sixty in under ten seconds and 118 miles per gallon fuel efficiency fill out the sexy stat sheet, though sadly there are no productions plans as of yet. The concept is being exhibited in the BMW Museum in Munich, but if you can't make it over to Germany right now, there's a video for you after the break.

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.

Toyota to introduce plug-in hybrid for 2010, hybrid versions of all cars by 2029
Toyota continues to lead the silent race to efficient cars with plans to introduce a plug-in hybrid in 2010 that will use lithium-ion batteries. Meanwhile, Toyota has been working with Matsushita Electric Industrial Co to develop batteries that will outperform lithium-ion batteries for its plans to introduce hybrid versions of every single car in its lineup between 2020 and 2029. If that seems too far away, the next generation Prius, due next year, will use NiMH batteries. Toyota president Katsuaki Watanabe told reporters in Tokyo that it's time to move past oil and get serious about electric power. "Our view is that oil production will peak in the near future. We need to develop power train(s) for alternative energy sources."

Triac: the highway-capable, three-wheeled electric car available now?
Our siblings over at AutoblogGreen discovered a little video hinting that a new three-wheeled, 70MPH electric car called the Triac is available... now. While we wait for the Aptera to hit the road, it seems Green Vehicles went ahead and made the Triac, tested it, and got it all sorts of market-ready. For those who don't know, the Triac is highway capable and will go 120 miles before needing a recharge. Video after the break.

Moletech Fuel Saver theoretically saves fuel
Add Moletech to the growing list of companies trying to cash in on going green -- they claim their new Fuel Saver cuts down on emissions and improves fuel economy in all fossil fueled engines. After some preliminary testing the California Environment Engineering Center for Environmental Research seems to agree that the device does actually work, but until more rigorous assessments are made your, uh, mileage may vary. The "universal product" comes in eight models to fit any size vehicle from cars to scooters to boats, with prices ranging from $119 to $299 USD. If you install one in your Prius and start contributing back to the grid, be sure to let us know.

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]
