The 2011 Ford Fiesta is officially the most fuel efficient model in its class, with the EPA announcing today that the ultra-funky hatchback and sedan rates in at 29 mpg in the city and 40 mpg on the highway when equipped with the smooth shifting six-speed PowerShift dual clutch transmission. To put...

It's pretty rare when a group of drivers begs a government agency to regulate them. But when it could avert what they think would be even worse regulations from another agency, anything's fair in love and war. The drivers in this case are the nation's long-haul truckers or, more precisely, the...

It's been one of the most-asked questions about the 2011 Chevrolet Volt extended-range electric car: So what kind of gas mileage will it get? Despite confusion around Chevy's claim of 230 miles per gallon, what people wanted to know was simple: After the battery is depleted, when the car's...

The other shoe has dropped: Yesterday, two U.S. government agencies jointly announced the final fuel-economy rules for model year 2012 through 2016 vehicles, giving automakers a single national set of standards and averting the threat of state-by-state regulation. Starting with 2012, automakers...

The trend started in Europe, and now every car make seems to have a green sub-brand. For a while, Chevy used the "XFE" label, but its highest-mileage 2011 Chevrolet Cruze is to be called the Eco. The EPA hasn't released final gas-mileage figures, but Chevrolet expects the 2011 Cruze Eco to be rated...

When automakers and the Obama White House announced agreement on a single national standard for emissions and fuel economy last May, the entire auto industry heaved a huge sigh of relief. The issue was settled, at least until 2016. Yesterday, however, the state of Texas filed suit in the U.S. Court...

So what exactly IS a "green car"? At both the Los Angeles Auto Show and Detroit Auto Show, you could find the word "green" all over the place. LA has been pitching itself for years as the greenest auto show, with fewer muscle cars and more hybrids, clean diesels, and so forth than any other U.S...

You have to give corporate PR guys some credit when they publish an article on the astoundingly high mileage their car got in a road test, and then dismiss the whole thing as "silly and totally unscientific." That's what Lexus magazine auto editor Clark Heideger did. When a coworker got 47.4 miles...

The dirty little secrets of Top 10 lists are in the methodology, as Forbes found out with its weirdly inaccurate "10 Dirtiest Cars" list. (It's the end of the year, so it's time for a lot of Top 10s.) But we see no such problems in the EPA Green Vehicle Guide, which rates vehicles not only on...

If you're one of the 120,000 people who own a Honda Civic Hybrid made between 2003 and 2008, you may already know about the proposed settlement to a lawsuit against Honda contending its advertising overestimated the gas mileage of your car. If you're not aware of the suit, read up quick. EPA...

Once again, Honda has the most fuel-efficient model range of the nine carmakers that sell a full lineup of vehicles in the U.S. Preliminary figures from the U.S. Environmental Protection Agency showed Honda averaging 23.6 miles per gallon across its 2009 vehicles, closely trailed by Hyundai (23.4...

That old capitalist tool, Forbes magazine, has issued a list of the 10 dirtiest cars sold in the U.S. At the very top, in first place for filth, is the Jeep Grand Cherokee. But it turns out there are some problems with their list. There's history behind this. A decade ago, the website for Forbes...

We seem to be covering the 2010 Volkswagen Golf TDI clean diesel hatchback an awful lot here, but a recent blog post raised an issue we hadn't considered: How far can the 2010 Golf TDI go on a single tankful of diesel fuel? The question comes from blogger, host of #carchat on Twitter, and general...

Gasoline may be averaging around $2.50 a gallon right now, but gas mileage remains an important factor in choosing a new car. Now the EPA has released 2010 fuel efficiency figures for all new cars and trucks sold in the U.S. Hybrids from Ford, Honda, Lexus, Mazda, Mercury, Nissan, and Toyota...

We don't hear so much about ethanol these days, now that gasoline is back down to $2.50 a gallon. But we still get e-mails, so here's a post to answer the question: What's going on with flex-fuel cars? Short answer: Manufacturers are slowly increasing the number of vehicles they build that can...

With record unemployment numbers and an active global recession, it's not news that vehicle sales have been lousy, falling by more than one-third from the record levels of a few years ago. But at least one maker's green cars are doing better than ever: Ford's U.S. sales of its hybrid-electric...

We've known for a while that BMW would launch its first hybrid this year, and now we know when: The 2010 BMW ActiveHybrid X6 will reach dealers this December. We'll be driving the hybrid X6 in a couple of weeks, but meanwhile, here's our advance preview of BMW's hybrid-electric sport-activity...

Between car loans, trade-ins, and special promotional incentives, most people rarely write a large check for their new car purchase. But what you can get for $10,000? What's the absolutely simplest, least expensive car on the U.S. market today? Actually, there are two: the 2009 Hyundai Accent and...

One of our most popular posts in August was a piece that broke down how General Motors projected a fuel efficiency of 230 miles per gallon in the city for its 2011 Chevrolet Volt extended-range electric car. Soon after GM's elaborate press event, Nissan announced with a straight face that their...
