Fuel Efficiency

Think "hybrid" and what comes to mind? Small or midsize, sometimes odd-driving Toyotas? There's now actually a raft of low-volume hybrid luxury and sports sedans from such makers as Mercedes-Benz, BMW, Lexus, and now Infiniti. The 2012 Infiniti M35h Hybrid was officially unveiled at last fall's...

With fuel-efficiency and emissions regulations tightening all over the world, carmakers continue to push the limits on how economical a production car can get. The latest entrant in the high-mileage stakes: a future edition of Volkswagen's Up minicar that will return 79 miles per gallon using a...

Although EPA gas-mileage ratings may or may not be achievable in real-world driving conditions, they're a good relative benchmark. They're also a very public encouragement to carmakers to make more fuel-efficient cars. Hyundai, whose new 2011 Elantra compact model is rated at 40 mpg highway for all...

Electronic driving coaches designed to promote more fuel efficient driving are nothing new and have been appearing in production cars for the past several years, mostly in hybrids but regular models too. Some memorable driving coaches include Nissan’s Eco-Pedal, which works by activating a...

Despite criticism from the auto industry, it looks like the EPA may be sticking to its guns and planning to launch new redesigned gas-mileage stickers for new cars that feature a prominent letter grade. The letter-grade scheme was one of two alternatives introduced for public comment last August...

Automakers all over the world are adapting their engine strategies to the need for higher fuel efficiency and lower carbon emissions. From mass-market to high-end luxury, engines are getting smaller and more efficient, using direct injection and turbocharging to wring higher power from lower...

What's good gas mileage? 30 mpg? 40 mpg? The 50-mpg combined rating of the 2011 Toyota Prius, the most fuel-efficient car sold in the U.S. this year? Nah. How about 261 miles per gallon? Or, for the Europeans in the house, a mere 24 grams of carbon dioxide per kilometer. You heard right. The...

Three government agencies agree to "coordinate" their actions and announce "a single timeframe" for proposing new rules. This signals "continued collaboration" among the trio. Yawn. But actually, this is a bigger deal than you might think. In the 10 months since President Barack Obama announced a...

Mercedes-Benz likes to launch technologies and lead trends, but sometimes they follow along with the crowd. In this case, Hyundai's doing it. Chevy's doing it. Chrysler's going to do it. Even Porsche will be doing it. And now Mercedes-Benz has joined the gang: The luxury carmaker too will fit a...

While the styling of Buick’s new compact sedan has been known for some time now (a version of the car was unveiled last year in China as the Excelle GT), we finally get a look at the North American model, which will be making its official debut next week at the 2011 Detroit Auto Show. Set to...

Many readers on this site are concerned with miles per gallon, or how much fuel their car uses. And while any site called Green Car Reports is bound to have an environmental tilt, most car buyers are far more concerned with saving money than saving the planet. Nonetheless, we're all about making...

We love looking back to see what's been popular over the course of a full year. And 2010 was definitely chock-full of green car news. Our 10 most popular posts this year are a little less random than last year's most popular, which featured Muslims and ethanol, urine, hybrid Ferraris, and our...

Even if you may not have heard of the Peak Oil theory, everyone knows that we'll continue to use more and more gasoline in years to come. Right? Well, errrrr, no. Maybe not. At least, that's the conclusion of both industry analysts and the oil companies themselves. The peak year for U.S. gasoline...

Today's small cars are better than they've ever been, even if few of them are among the EPA's all-time gas mileage champs. And spurred by tighter fuel-economy laws, 40 miles per gallon on the highway is becoming the new target for subcompact and even compact cars. There's just one little problem...

Every now and then, readers write to grumble about new cars and their gas mileage. The gist is usually something like this: You wrote that the new 2011 [Make & Model] gets 40 mpg highway? Well, big whoop-de-doo. I always got at least 45 mpg in my 1992 Geo Metro, and it was a whole lot cheaper...

The U.S. launch of the 2011 Hyundai Sonata Hybrid has slipped a month, just enough to preclude buyers from taking advantage of a $1,300 Federal tax credit that expires December 31. According to Hyundai, the first cars will now reach dealers in January or perhaps later, rather than in early or mid...

One of the main reasons buyers steered away from the old Ford Explorer sport utility vehicle, according to Ford itself, was its fuel economy. So gas mileage had to be a major selling point for the all-new 2011 Ford Explorer. Like so many new cars and crossovers, the latest model does indeed get...

Just a month ago, we suggested that 40 miles per gallon is the new bragging threshold for subcompact and even compact cars. Now, Hyundai has dropped the gloves (or thrown down the gauntlet) with a clever marketing campaign to contrast it with other makers: It will start breaking out the sales of...

For many years, Honda was routinely awarded the title of greenest carmaker in the U.S. market. But its most recent green cars have stumbled, and a dark-horse competitor is rising fast toward taking the coveted title, conferred every few years by the Union of Concerned Scientists. It's not Nissan...

The shenanigans continue. Just this week the Nissan LEAF was rated at 99 mpg-equivalent by the EPA, raising the ire of our own John Voelcker--and justifiably so. Today, the Volt gets similar treatment and a similar rating, but only in EV mode. Add in the gas-only mode's 37 mpg rating and the...
