Fuel Efficiency

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...

All-wheel-drive is an increasingly popular option in new vehicles, especially in areas of the country that get snow. But the security of having all four wheels powered in your car can be offset by the price of the option and, in most cases, a significant gas mileage penalty. And these days, it's...

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...

The Frankfurt Auto Show just wound up today, and most of the concept cars focus on lowering carbon dioxide emissions. Volkswagen, for instance, launched a two-seat "1-Liter" concept car that gets a remarkable 170 miles per gallon. But suppose all the money we're investing in better gas mileage and...

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...

With gas prices top of mind for many drivers, the 2011 Chevrolet Cruze Eco model seems perfectly timed. The model with a six-speed manual gearbox is EPA-rated at 28 mpg city, 42 mpg highway, for a combined 33 mpg. On our recent road test over a long weekend, we beat that slightly, getting 34.2 mpg...

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...

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...

We rarely think about what's in our gasoline when we fill the tank, but carmakers have to. Mercedes-Benz has just launched a new direct-injected 3.5-liter V-6 engine in its 2012 SLK model, with an innovative "lean burn" mode that will also be used on a smaller four-cylinder engine. The "Stratified"...

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...

With political uncertainty in oil-producing states, and the rising gas prices that brings, you can expect to see a lot more headlines saying "40 MPG!" We just did a quick overnight road test of a 2011 Chevrolet Cruze Eco with the six-speed manual transmission, which the EPA rates at 28 mpg city and...

Gas prices got you all nervous? Figuring the days of cheap gas are over? Thinking about a new car with much better gas mileage? Well, just because the EPA rates a specific car at the magic 40-mpg mark doesn't mean you'll actually get 40 mpg. But the ratings are a good indicator of where cars stand...

You may have seen it on a t-shirt: "40 is the new 30." But you may not have realized it applies to miles-per-gallon just as much as age. While cars with EPA ratings of 30 mpg or more used to be considered in the highest ranks of fuel efficiency, now 40 mpg seems to be the new benchmark for...

Next year's Mazda3 models will deliver fuel efficiency gains over their 2011 counterparts, the company said today, as it unveiled refreshed versions of its popular compact hatchback and sedan, to go on sale later this fall. The 2012 Mazda3 will offer as an option what Mazda now calls the SkyActiv-G...

Writing about green cars can be a challenge. On the one hand, this site attracts many new-car buyers who want to learn more about more fuel-efficient alternatives to what they're driving now. Consider the Ford Explorer driver who bought a Honda Fit because it was really all he needed. But on the...
