Fuel Economy

How do you get better gas mileage from engines that create the same power as what you've built your brand on? If you're BMW, the answer is that you launch an entirely new family of small engines derived from the world-famous inline six-cylinders you're famous for. But if you're fitting them with...

The 2013 Volkswagen Jetta Hybrid is VW's second hybrid model, and the first hybrid sedan we've had in the U.S. market from the German automaker. It's also interesting because the Jetta is available with a fuel-efficient TDI turbodiesel engine--and VW discovered that hybrid and diesel buyers are...

We've written quite a lot about the gas mileage of Ford's two new 2013 hybrid models, the C-Max and Fusion hybrids. That's because a lot of shoppers and buyers have been talking about it. Both cars are rated at 47 mpg combined, and neither car seems to achieve anything close to that rating in...

The 2013 Ford Fusion Hybrid is the second of Ford's two hybrid models, both all-new for 2013. The Fusion Hybrid, unlike the C-Max Hybrid compact hatchback, is a four-door mid-size sedan aimed right at the heart of a high-volume market segment. Competitors for the Fusion lineup include the Toyota...

Obviously, fuel economy will be an increasingly big deal in years to come. The gas-mileage ratings of new cars and trucks must double (and then some) between last year and 2025. But as two recent news events pointed out once again, EPA mileage ratings on the window stickers of new cars may not be...

The quest toward better gas mileage and incremental gains isn't relegated just to engine and transmission improvements, or to aerodynamics or weight reduction. Even when we're not talking hybrids, the move to smart electric components can bring some significant gains. Beyond electric power...

Every month, the University of Michigan sends out its weighted average of the gas mileage of all new cars sold the previous month. And for January, the news is good. The new vehicles sold in the U.S. during January scored a sales-weighted average fuel efficiency of 24.5 mpg. That's up 0.4 mpg from...

We tend to like small cars, as a personal preference. But the very smallest of cars often don't get the best gas mileage, and they can feel subjectively unsafe in some driving conditions. So how did our 2013 Chevrolet Spark minicar do on gas mileage? We've concluded that--depending how you use...

There's good news and bad news for green car fans in the latest J.D. Power and Associates Avoider Study. For a decade, that study has interviewed recent car buyers, asking detailed questions about their purchase decisions. As you might guess from the title of the survey, Power focuses not only on...

The Jeep Grand Cherokee isn't usually what people think of when you say "green car," but the new diesel version that's coming for 2014 moves it somewhat closer to that category. Unveiled first thing Monday morning, the 2014 Jeep Grand Cherokee EcoDiesel is part of an updated 2014 lineup for the...

The 2013 Ford C-Max Hybrid is a comfortable, quiet, well appointed five-door compact hybrid hatchback that appears to get 35 to 40 mpg in most real-world usage. But it is not a 47-mpg car, from the bulk of the evidence available. The C-Max is selling well--much faster than the original Prius did...

In olden days, new models for the following year came out in September. Now, they're all over the calendar. The latest example is the 2014 Mazda Mazda6 sedan, of which several hundred already sit in Mazda showrooms across the country. Its highly efficient 184-hp SkyActiv 2.5-liter four-cylinder...

GM's full-size hybrid pickups, the Chevrolet Silverado Hybrid and GMC Sierra Hybrid, for much of the time they've been on sale, have offered the highest gas mileage of any full-size truck on the U.S. market. Yet these hybrid pickups, which were introduced for the 2009 model year, have been...

Ford is now clearly worried about the mileage ratings of its new 2013 Ford C-Max Hybrid and 2013 Ford Fusion Hybrid. Company officials said on Friday that while they complied with all EPA test requirements, a driver's individual style is critical to achieving published fuel-efficiency numbers. Both...

There was exactly one gas-mileage number contained in a pair of press releases Ford issued this morning. It was the prediction that one version of its 2014 Ford Transit Connect small commercial van will achieve "up to" 30 mpg on the highway cycle. It's called counterprogramming: In the midst of...

The past couple of years, auto industry headlines have focused on 2025 and its high benchmarks for corporate average fuel economy. But there's a nearer-term deadline that's fast approaching, and it comes with its own set of emissions and fuel-economy standards. The good news is that many cars on...

Not all green cars are hybrids, diesels, or plug-ins. And with new fuel economy regulations now set through 2025, all cars are going to get more efficient--gasoline cars first and foremost. The new 2013 Nissan Altima mid-size sedan has the highest EPA rating for combined gas mileage of any gasoline...

Mazda is pushing ahead with its plans to offer a clean-diesel four-cylinder engine that could prove to be a strong rival to the TDI four in some Volkswagen and Audi products. While the 2014 Mazda6 will arrive in its lower-priced form with a 184-horsepower, 2.5-liter version of the four-cylinder...

Along with the new, ultra-fuel-efficient 2014 Ford Fiesta with the 1.0-liter EcoBoost three-cylinder engine, Ford's subcompact gets a number of other changes for the 2014 model year. These include a revised interior that adds a 6.5-inch LCD touchscreen display and optional MyFordTouch infotainment...

This is starting to look not so good. It appears that two new hybrid cars from Ford--the 2013 C-Max Hybrid hatchback and the 2013 Fusion Hybrid sedan--may not deliver real-world gas mileage that's anywhere near their 47-mpg EPA ratings. Automotive journalists have been quietly discussing this for a...
