63EPA to scrutinize auto fuel economy tests, issue revised guidelines

Following the lowering of estimated fuel economy figures from companies like Ford, Hyundai, Kia and even a handful of Mercedes-Benz sedans in the recent past, the Environmental Protection Agency is cracking down by mandating new mileage testing procedures by the end of the year, after first considering some changes months ago. The improved evaluations should make the numbers that buyers see on the window sticker of a vehicle closer to what they experience in the real world.

AddMay new-vehicle fleetwide fuel-economy remains at record 23.7 mpg

Former NBA great Shaquille O'Neal retired with a career scoring average of 23.7 points per game. And like Shaq's scoring average, the new-vehicle fleetwide fuel economy mpg number doesn't want to budge, either.

AddFord hit with another lawsuit over C-Max, Fusion Hybrid mpg claims

Ford is waiting to see if it will be facing several class action lawsuits over its mileage ratings - three of which were filed in late April. Suits filed in federal courthouses in Massachusetts, Pennsylvania and California claim Ford is overstating the average mileage ratings for its 2013 Ford C-Max and Fusion Hybrids.

AddHyundai, Kia owners accept fuel economy apologies, love their debit cards

Hyundai and Kia may have gotten lots of bad press for inflated fuel economy ratings, but the on-the-ground reality isn't all that bad. Automotive News says that dealers have been pleased at how the parent companies have handled the November scandal and the reimbursement programs are making customers happy and them back in the door.

AddIowa newspaper finds no problems using E15; biofuel could have saved drivers $69m

There's been a lot of concern expressed over the potentially damaging impact on engines that E15 – gasoline with 15 percent ethanol – could have on vehicle engines. AAA most recently sounded an alarm on the issue – the organization says that sale of E15 gasoline should be postponed until consumers can be educated on the fuel – and using the fuel can void the warranty in some vehicles.

34Will fallout from Hyundai and Kia's MPG issues hurt resale values?

First came Hyundai's and Kia's corporate admission of guilt about overstating fuel economy numbers, then the recompense, then the lawsuits. Now begins the process of gnawing on every one of the consequences. In case you've only just returned from the International Space Station, Hyundai and Kia have admitted that about a third of the cars they have sold over the past three years have advertised inflated EPA fuel mileage numbers. For instance, the highway mpg number for the 2013 Hyundai Accent is

AddFleets and consumers now see practical alternative-fuel vehicle options

Automakers and fans of alternative fuel vehicles have been waiting for years for consumers to start rolling off dealer lots driving green cars. It is slowly starting to happen, with the number of vehicles that don't run exclusively on standard gasoline nearly doubling from 534,000 on US roads in 2003 to almost 940,000 in 2010, according to US Energy Information Administration. The numbers have only risen since then, and are expected to increase in the coming years – Pike Research is foreca

AddFord C-Max Hybrid requires disciplined driving to hit 47 mpg

Ford, and other automakers selling hybrid electric vehicles, may need to place a warning label near the city/highway miles per gallon label on the car's window sticker: "WARNING: Your average fuel economy will be determined by your driving conditions, including speed traveled on highways and how you apply your braking."

44NY Volvo owner closing in on 3 million miles in P1800S [w/video]

If you've been following these pages for a while, you may remember Irv Gordon and his 1966 Volvo P1800. The duo have found their way onto these pages twice before: first back in 2007 when the machine cruised past 2.6 million miles and then again in 2011 when the machine picked up an additional 300,000. Now Gordon has just 34,000 miles to go before rolling past the three million mile mark. He bought the coupe brand-new in 1966, and while the engine has been rebuilt twice in the intervening 46 yea

AddChevy Volt, Chevy Cruze Eco square off in 1,000-mile showdown

It's been argued that General Motors' halo vehicle, the Chevrolet Volt, is more or less a bait and switch bit of technology dreamed up by folks at GM for one reason: to draw buyers into showrooms. Once there, loads of potential Volt buyers opt for the Chevy Cruze Eco instead of the pricey plug-in hybrid.

532011 Ford Explorer with EcoBoost 2.0-liter delivers 30% better fuel economy than V6

Ford has got the gas mileage goods on its 2011 EcoBoost-powered Explorer, and it's news you might like if you want one: you'll get 30 percent better mileage with the inline-four than you could with the outgoing V6. Ford did, however, leave a key detail out of the press release touting this: it didn't reveal the actual mileage number, "pending EPA certification."

AddPay-per-mile car insurance might come to California

The idea of paying for your insurance by the mile is not new. MileMeter, in Texas, offers pay-as-you-drive (PAYD) rates and California has been using mileage brackets to set insurance rates for years. A new, more precise PAYD system is under discussion in California that would give people who drive less a financial incentive to do keep doing so – and maybe convince people on the fence to find an alternative when possible.

AddMileage tax gains support of House Transportation Committee chair

Earlier this year, new Transportation Secretary Ray LaHood (R) briefly flirted with the idea of a mileage tax, where drivers would pay based on how far they drive. Briefly. Later, the State of Oregon released a study that found a way to "successfully" implement a mileage tax - GPS units and a wireless communicataion system at the pump were two key components - but this didn't address the big problem with a mileage tax: it removes any tax-based incentive to consume less fuel (a gas tax, on the ot

AddMiles per gallon: Overrated?

Sure, there are plenty of things in the automotive world that are overrated. Enough, in fact, to compile a whole list of them, as seen here. Come on, join in... it's fun! For instance, in addition to the small SUVs that already made the list, why not add big SUVs too? Most buyers of the big behemoths rarely use the full capabilities of their rigs and could almost always use a smaller vehicle. What about those rare instances when a monster 'ute is necessary? Rent one. Remember, even if one more g

AddCar and Driver looks at mileage myths and misconceptions

In the latest issue of Car and Driver my friend Mike Austin has taken a look at a variety of different beliefs that people have about what saves fuel when driving. As we all know by now, driver behavior does have a major impact on fuel consumption. Mike and his test colleagues went out and ran mileage tests evaluating factors like using air conditioning vs. having the windows down vs. the sunroof open, removing extra stuff from the trunk, and running with stuff tied to the roof. The A/C vs. wind

AddEarth Day: How much energy would the U.S. save if ten percent of the population switched to hybrids

We here at AutoblogGreen are big on technology that can lower environmental impact. Hybrids are widely touted as one way of doing that although some are much better at it than others. With over a million of the most popular hybrid, the iconic Prius, being sold there must be a noticeable decrease in the amount of gas being burned by Americans, right? Have you ever wondered how much gas would be saved if we all drove a Prius? About half, unless we all drive like Danika. OK, that's an unlikely scen
