Low gasoline prices and fuel economy, revisited
From plunging fuel prices to soaring SUV sales, several factors have emerged that could plausibly impact fuel economy performance.

Today’s energy efficient cars strive to meet CAFE standards
The looming 2025 federal Corporate Average Fuel Economy (CAFE) goal of 54.5 miles per gallon across an automaker’s fleet is one of the driving factors behind a series of advancements in more-efficient engine and powertrain technologies.
Is it time for Greens to reassess their opposition to ethanol?
For almost as long as there have been cars, gasoline has been the dominant fuel in transportation. But for a host of reasons — environmental, climate change, public health, and economic — the time has come to consider mixing higher blends of biofuels with gasoline.
How CAFE works: 5 things you should know about gas-mileage standards
As automakers and policy wonks fret and fuss over future fuel economy standards, interested spectators may be lost in the fumes. What exactly are Corporate Average Fuel Economy standards, and what’s important to know about them?
It’s time for an octane boost
The most promising and economical approach identified by the automakers is to greatly expand the use of turbocharging and high compression ratio engines. And that will require an increase in the octane rating of our gasoline.
The E15 perspective from those marketing the fuel
The argument among those marketers and retailers that have embraced the fuel is that E15 fuel allows them to market a cleaner-burning, higher-octane fuel that can technically be used by more than 200 million cars on the road today, and it can typically cost less than the E10 competitors are selling.
Study: 2025 EPA fuel-economy targets would save drivers thousands
Americans who drive could save between $3,000 and $4,200 over the life of their vehicles if the government does not reduce the 2025 fuel economy standards that could be revised by early 2018, according to a study released today by Consumers Union.
American cars on track to double fuel efficiency
A growing number of vehicles are meeting or surpassing federal fuel economy standards, though improvements to cars outpace those to trucks, according to a new analysis by the Consumer Federation of America.
Automakers beating fuel economy expectations despite an upswing in truck/SUV sales
SUVs and pickups, while still lagging the leaders with regard to fuel economy, are holding their own. Models rated at less than 16 mpg are down to just 4% of the nation’s new-vehicle fleet, compared to nearly a third of the market in 2008.
Carmakers continue to meet rising CAFE goals, just as expected
The 54.5 mpg standard, which equates to about 40 mpg on new-vehicle window stickers, is the backbone of U.S. policy to reduce carbon emissions from cars and trucks. It has also been seen as a daunting technical challenge for carmakers—but one, it turns out, that they’re largely meeting.
