Fuel Economy

The 2011 New York Auto Show is kicking off this week, with new compact car entries that include the all-wheel-drive 2012 Subaru Impreza, among others. But a strong new contender this year that's already selling fast is the 2011 Hyundai Elantra, which we recently road-tested over our usual route of...

Oh, the pain. We hear about all those special European models with astoundingly high gas mileage ratings, and we wonder, why can't we have them here? The latest is the 2012 Ford Focus ECOnetic, which goes on sale in Europe later this year. During its debut yesterday at the Amsterdam Auto Show, Ford...

Americans aren't stupid. We're just badly informed. And occasionally, stubborn. Why else would we ignorantly cling to using miles per gallon as the way to measure how efficiently a car uses fuel? But maybe you don't quite see the problem. OK, so here's a little test: Which saves more gasoline...

Sure, it'd be nice to have a brand-new, more fuel-efficient vehicle. But not everyone is able to buy one of the growing number of new cars with at least 40 mpg highway mileage. So here are our tips for getting better mileage out of whatever vehicles are in your driveway right now, today, from...

This week is the heart of tax time. If you're like many other taxpayers or a small businessperson, right about now you're looking up the 2010 mileage rate that the IRS lets you use when deducting personal-vehicle use as a business expense. So here's the answer: The IRS mileage rate is 50 cents per...

We're barreling toward the 2011 New York Auto Show, where media days kick off in two weeks. While concept cars like the Lexus LF-Gh luxury hybrid sports sedan will get lots of attention, once the media leave, actual car buyers will be just as curious about fuel efficient cars with high gas mileage...

Cutting carbon emissions is complex. And there are a lot of myths and misinformation out there. The effective impact of some actions--reusing your grocery bags, for instance--is relatively low. Other methods, things that many people never even consider, are considerably more effective. For...

Throughout the history of the internal combustion engine there have been a multitude of scientists, inventors and entrepreneurs shouting claims about revolutionary new engine designs promising greater efficiency, more power, fewer emissions and lower production and running costs. However, to this...

MPGs matter, it turns out, even to pickup buyers. Or, perhaps especially to pickup truck buyers. Just four months after Ford added an EcoBoost engine option to its top-selling F-150 pickup truck, the company reports that fully 35 percent of the 2011 model's sales are fitted with either that...

What are the tricks that car designers and engineers use to squeeze out those last few miles per gallon in your next new car--regardless of what size it is? In our continuing series of videos on ways to drive a little greener and stretch your gas budget that much further, editorial director Marty...

To date, Buick and "fuel economy" haven't often been used in the same sentence. But the 2012 Buick LaCrosse, the brand's largest surviving car, will offer one engine option that's projected to deliver 25 mpg city, 37 mpg highway. That's not bad for a midsize near-luxury sedan (though 1 mpg lower on...

Gas mileage is on absolutely everyone's mind these days. Strife in oil-producing nations, and the associated rising gasoline prices, have already led to a surge of interest in any vehicle's MPG ratings. Now production in Japan (source of most of the world's hybrids) is shut down, at least...

Expect to see smaller engines for BMW’s future models, as high fuel prices and greater environmental concerns push automakers towards engines with lower displacements. We’ve already seen this trend with the recent announcement of BMW’s new TwinPower Turbo 2.0-liter four-cylinder...

The EPA rates the 2011 Chevrolet Cruze Eco at 28 mpg city, 42 mpg highway, when it's fitted with the six-speed manual transmission. But can the Cruze Eco really reach beyond that magic 40-mpg number, which is highway mileage only? VIDEO: 2011 Chevrolet Cruze Eco, Our Real-World Gas Mileage On our...

Americans rarely think much about zoning, but it governs almost every facet of how we live our lives. And unintended consequences of 50-year-old zoning codes may be about to turn some of our loveliest and quietest suburbs into the next slums. Why? Simply because they've been built too far away from...

While many Americans may still scoff at the idea of driving a reasonably sized car with an engine not much bigger than that found on a motorbike, sales numbers are showing that the tide is starting to turn and this archaic negative perception towards smaller engines may soon alleviate altogether...

At just over 2,300 pounds, the Mazda2 is a lightweight. It's about 200 pounds less than the Honda Fit, MINI Cooper, or Ford Fiesta, and a bit less than the Toyota Yaris even. And, Smart Fortwo aside, that makes it the lightest regular production vehicle for 2011. Lighter weight and smaller engine...

For every new vehicle that gets sold in the United States, four used cars change hands. Those new cars have nice, big window stickers showing their EPA-rated gas mileage figures. Used cars? All you get is the seller mumbling something like, "Oh, yeah, it always gets, ummmmm, at least 25 miles a...

The recent spike in oil prices has got the whole world focused on fuel consumption, so much so in some parts that countries are lowering their national speed limits in an effort to reduce their national fuel consumption levels. One such country is Spain, which reduced its speed limit for cars from...

It’s the age-old question: Why do we still not have the wide range of clean-diesel models that automakers have offered to the rest of the world for decades? It’s proven that diesel powered cars can offer hybrid-like fuel economy--even better in some situations--as well as thrilling...
