Fuel Efficiency

New Federal standards for higher average gas-mileage in vehicles sold from now to 2015 will save consumers money on fuel. But the cars themselves are likely to cost more, according to a study released yesterday by the National Research Council. Regular readers know we've been saying that it'll be a...

Our reader Celeste wrote to ask us about available hybrid SUVs and crossovers, and we thought our answer might be useful for the site. At the moment, there are three main hybrid SUVs sold in the U.S. Each of them also has variations sold under other brands. All are likely to be durable, as their...

We're eagerly looking forward to the arrival of the 2011 Ford Fiesta, the first truly modern subcompact from Ford in many years. The greenest Fiesta is rated at 40 miles per gallon on the highway, and the car has been widely praised for its dynamic styling, the high-quality interior, and an array...

Over the last year, the U.S. Department of Energy has granted almost $9 billion of low-interest loans to help automakers retool for more fuel-efficient cars. But until now, General Motors and Chrysler had been shut out while Ford, Nissan, and Tesla were awarded loans last June, joined by Fisker in...

Yeah, yeah, we know. The only people who buy hybrids are the ones who want to show off their green credentials. They're effete, elite coastal residents who probably drove Subarus before they got their hybrids. Uh huh. Tell it to the Marines. Or, more accurately, tell it to the Israel Defense...

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...

Going green on the road may involve smaller engines, electric cars, and clean diesels, but it also requires making all engines far more fuel efficient. To that end, General Motors will announce this morning that it will invest almost one billion dollars in five separate plants to build a new, far...

Just a month after being turned down for low-interest loans by the U.S. Department of Energy, the reclusive V-Vehicle Co. has shown a drivable prototype of its affordable, green V-Car to Louisiana governor Bobby Jindal and members of the press in Baton Rouge. While no photos were allowed, many more...

Today is Earth Day, and in honor of that event--it started 40 years ago as a nationwide teach-in on environmental issues--we bring you a list of the greenest cities in the United States. It's not actually our list; it comes from Cars.com, which based its ranking on the percentage of car shoppers...

What a shock! Who'd ever have thought it? Will wonders never cease? Yes, yet another survey shows that fuel efficiency matters to car and truck buyers. And that more than half say their next vehicle will get better gas mileage than their current ride. Fuel efficiency: It matters Capital One Auto...

We've written already about the 2011 Chevrolet Cruze Eco high-mileage model launched at the New York Auto Show. Now we've had a chance to sit down with Gary Altman, GM's vehicle chief engineer for compact cars-North America, and find out exactly how they did it. In addition to predictable...

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...

Looks like secretive startup V-Vehicle Co. won't be joining Ford, Nissan, Tesla, and Fisker in getting government guarantees for low-interest loans to invest in advanced vehicle technology. Yesterday the U.S. Department of Energy turned down a $321.1 million loan application by V-Vehicle (VVC)...

At December's Los Angeles Auto Show, Hyundai made a big splash by saying it would no longer offer V-6 engines in its Sonata midsize car or its Tucson compact crossover. Instead, it replaced them with higher-performance, more fuel-efficient four-cylinder motors. But Hyundai's just one of many makers...

Just yesterday, we reported on Ford's first-ever 300 hp/30 mpg ratings for the 2011 Mustang. The company has vowed to achieve best-in-class fuel economy numbers for every new model it launches. Certainly the 2010 Ford Fusion Hybrid clears that bar, trouncing any other mid-size sedan with an EPA...

Ford's on a roll lately, selling more cars in the U.S. than General Motors last month. And it's vowed to achieve best-in-class fuel economy numbers for every new model it launches. So the news today that its revised 2011 Ford Mustang with the 3.7-liter V-6 engine has been rated at 19 mpg city, 31...

As we keep saying, one of the ways that automakers will meet more stringent fuel economy regulations is by making smaller engines that work harder. Now Fiat has one-upped its European competition by announcing it will offer a 900cc turbocharged twin in European models of its Fiat 500 mini-car. That...

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...

Continuing the trend of raising gas mileage by using smaller, more powerful engines, Ford is set to launch its first four-cylinder EcoBoost engine in the 2011 Ford Edge, which will be unveiled at the 2010 Chicago Auto Show next week. We've written before about Ford's EcoBoost system, which uses...
