34US fuel economy average down for the first time in four years

It's almost impossible not to notice that it's a lot cheaper to fill up at the gas station in the latter portion of this year. As of December 1, the US Energy Information Administration said the average cost of a gallon of gas was $2.778, down almost 50 cents from a year ago. In general, fuel prices have been on the decline for much of 2014, and the effects have started showing themselves with people seemingly more willing to buy lower efficiency vehicles.

53Ford decides C-Max shoppers not interested in fuel economy

If you say a car – the Ford C-Max Hybrid, for example – is "fun to drive," can anyone really come up with some empirical evidence against your claim? What about calling it "versatile"? We wonder if Ford has been thinking along these lines when it talks about the green little hatch.

6Hellcat no help to Fiat-Chrysler's bottom-of-the-pile mpg average

What, you expected the "fastest muscle car ever" to help fleetwide fuel economy? Nope, don't think that's going to happen. That means Fiat Chrysler will likely to continue to languish at the bottom of the heap when it comes to fleetwide fuel economy among the largest automakers serving the US, especially as the automaker starts to sell its Dodge Challenger SRT Hellcat. A few hundred Fiat 500E electric vehicles aren't going to turn the trend around.

7EPA study proves plug-in vehicles making their mark

Talk about a report both green-car advocates and gearheads can celebrate. The US Environmental Protection Agency (EPA) put out its annual Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends report. And the 148-page study has something for everyone.

48EPA Says New Vehicle Mileage Hits Record 24.1 MPG

Fuel economy is up almost 5 mpg since 2004

Gas mileage for new cars and trucks in the U.S. averaged a record 24.1 miles per gallon last year, but gains in fuel economy are slowing.

6284-MPG Elio Motors trike preorders get limited-time 50 percent bonus

For prospective buyers of Elio Motors' super-fuel-efficient vehicle set to debut next year, one day may cost you $250. For a car that costs $6,800, that's a decent chunk. You've been warned.

12AAA finds stop-start could save you $179 a year

That silence you hear? It's a month's worth of payments on the family car-insurance plan not being spent on an idling engine. That's one way to look at new numbers out from the AAA that say stop-start engine technology will save drivers a solid chunk of change in the form of lower refueling costs. If only more automakers would embrace the tech for their vehicles.

63EPA wants actual road-test results to fix auto fuel economy estimates [w/poll]

The agency thinks the new approach will result in more realistic ratings, especially for hybrids.

16UMTRI: average fuel economy in US climbs yet again

Go figure. That's what we're saying after fleetwide fuel economy of new cars purchased in January rose during a month when green-car sales fell yet again.

24Chevy Cruze diesel goes on 54.7-mpg cross-Canada journey

Oh, Canada, indeed. A husband-and-wife team set out to see what kind of fuel economy numbers they could get out of a Chevrolet Cruze Diesel on a transcontinental drive, and they ended up hitting some pretty impressive numbers. The team, according to their Driving.ca blog, averaged 4.3 liters of fuel use per 100 kilometers for their 5,956-kilometer (3,701-mile) jaunt from Vancouver to Halifax. That maps out to about 55 miles per gallon. And the drivers weren't total slow pokes, averaging about 50

10Ricardo says only 'minor electrification' needed to reach 2025 CAFE standards

Ricardo Plc appears to be adhering to an "it takes a village" approach to ratcheting up US fleetwide fuel economy levels to the higher Corporate Average Fuel Economy standards the federal government set for 2025. Last year, the US government finalized the new CAFE standards, which call for increasing fleetwide fuel economy starting in 2017 and ending at 54.5 miles per gallon (about 40 mpg in "real world" terms) by 2025.

AddMore automakers will use turbochargers to meet CAFE standards

Plug-ins may be getting a lot of the attention from folks looking to cut emissions, but no one is forgetting the good old-fashioned turbocharger. In the end, turbos might even have a far larger impact.

6With 23.7 mpg, March sets third-straight month of record-high fleetwide fuel economy

As the Beatles succinctly put it: "It's getting better all the time." That's how we can characterize US new-vehicle fleetwide fuel economy, which last month marked the third straight in which US new vehicles set an all-time record for fuel economy.

9Mobilis Trading proposes CAFE credit auctions

One Washington, DC-based startup is looking to create a market for trading automaker "credits" that will allow gas-guzzler makers to "meet" stricter US fuel-economy requirements during the next few years, Automotive News reports.

AddEPA finds 2012 fuel economy was highest ever, 23.8 mpg

The average fuel economy for a new car in the US made a record single-year jump, according to new data from the US Environmental Protection Agency. Fleetwide fuel economy rose a record 1.4 miles per gallon to an all-time high of 23.8 mpg, the EPA says. During the past five years, average new-vehicle fuel economy went up 16 percent while emissions decreased 13 percent. Check out the EPA's press release below and find further information here.

69Ford Fusion Energi boasts 620-mile total range, 21 in EV mode

The Ford Fusion Energi, the automaker's second production plug-in hybrid after the Ford C-Max Energi, officially boasts a range of 620 miles between fuel stops when calculated with EPA-rated figures (108 miles per gallon equivalent in the city, 92 MPGe highway and 100 MPGe combined). Of that distance, the sedan is capable of running 21 miles in electric-only mode.

34Iowa 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.

24Ford, Chrysler join Toyota in fighting high-MPG rules in Mexico

Automakers may have given in to the 800-pound gorilla that is the US government when it comes to more stringent fuel-economy standards. But the Mexican government? That's a smaller monkey that the companies are apparently more than willing to battle.

11Fuel economy numbers are increasing, but still have a long way to go to hit 54.5

The average fuel economy number for new, light duty vehicles sold in the US reached an all-time high of 24.1 miles per gallon in October, up from 23.8 mpg the previous month, according to a report released by the University of Michigan's Transportation Research Institute.

102012 model year was the greenest new U.S. auto fleet ever

To paraphrase the infamous Gordon Gekko from the movie Wall Street: "Green, for lack of a better word, is good."

189New CAFE rules officially finalized; 54.5 mpg is like making gas $1/gallon cheaper

Increasing the Corporate Average Fuel Economy standards for model year 2017-2025 cars to 54.5 miles per gallon was first proposed in July 2011. Since then, there has been a lot of back and forth, a lot of positive and negative responses, and, lately, a delay for unknown reasons. Since the CAFE rules were not changed between the mid-1980s and when President Obama came into office and rules for 2012-2016 model year vehicles were put in place in 2010, it's not a huge surprise this update took so lo
