Fuel Economy

Diesels: Dirty and slow, right? Only if you've never left the 1980s. Diesel engine technology has come along in leaps and bounds over the past two decades and the best of today's diesel vehicles easily offer a compromise between performance and economy to best equivalent gasoline vehicles. General...

It's widely accepted in the auto industry that all manufacturers game the test cycles used to establish emissions and gas-mileage ratings. Ask auto engineers about the topic, and they tend to get a faraway look and go silent. But the test cycles established in 1978 and used ever since are far from...

If there's one thing that illustrates the culture difference between the United States and Japan better than anything else, it's the cars everyone drives. In the U.S, the Ford F-Series truck has dominated the sales charts for quarter of a century. The smallest engine available is a 3.5-liter...

Life is so unfair sometimes. Car companies have been dangling the carrot of smaller and more fuel efficient vehicles in front of us for a few years now and though we've managed to grab vehicles like the MINI, Honda Fit and Ford Fiesta (and the Chevrolet Spark is on the way), we're still denied many...

Over several years, Mazda's i-Stop engine start-stop feature has helped owners in other markets to save on their fuel budget—and it's helped commuters in some of the most traffic-clogged areas be a little greener.

It’s official: Mitsubishi’s compact four seat electric car, the 2012 Mitsubishi i, is more fuel efficient than the 2011 Nissan Leaf. Rated by the Environment Protection Agency (EPA) for both fuel economy and range per charge, the Mitsubishi achieved a combined fuel economy of 112 miles...

Much debate will occur--and that's putting it politely--over the next round of gas-mileage standards, which the EPA hopes to finalize next year for 2017-2025 vehicles. Earlier this week, news reports from Washington indicated that the Obama Administration and EPA are pushing for 56.2 mpg as the...

The two Federal agencies that set gas mileage and emissions standards for future cars may propose rules that require corporate average fuel economy to reach 56 miles per gallon by 2025. News reports out of Washington, D.C., indicate that the Obama Administration is urging the EPA and NHTSA to push...

When is a 2011 Chevrolet Volt not a plug-in hybrid? When it covers 2,500 miles between fill-ups. That’s how far Maryland resident Jeff Parmet has driven in his 2011 Chevrolet Volt in the past six months. In fact, he’s just visited the gas pump for the first time since buying the car...

The new car buying process can be quite the task in today’s market. This is especially true with the growing numbers of hybrid and electric cars added to the pool of choices. While hybrids and electrics don’t make up a large percentage of the market, miles-per-gallon (mpg) ratings are...

With gas-mileage standards through 2016 now in place, the EPA and NHTSA are turning their sights toward rules for 2017 through 2025. Proposals are floating around for CAFE standards of up to 62 mpg (which means the vehicles you might buy would average about 50 mpg in actual use). Ah, the hell with...

We've heard this script before. Some agency of the Federal Government proposes a new rule that will affect the design and performance of cars in some way, sometime in the future. Instinctively, reflexively, automatically, viscerally, the industry lashes out. Horror, catastrophe, misery, bankruptcy!...

The all-new, entirely redesigned 2013 Ford Fusion Hybrid sedan may be rated by the EPA as high as 47 or 48 mpg on the city cycle, according to reports on a website that follows Ford news. The redesigned Ford Fusion sedan will be largely identical to the next Ford Mondeo sedan for Europe under the...

Volvo likes to think of itself as a conscientious car company. "Why are we different?" asked Stefan Jacoby, Volvo's German CEO. "We are Swedish; we come from a human-centric company. We do things because they have a purpose for people." Safety, yes, but also green Those things used to revolve...

It happens every time. Gas prices go up sharply, and new car buyers suddenly decide that gas mileage is important--and shop accordingly. With gas around $4 a gallon in many parts of the country, what would you trade for higher miles per gallon? Would you pay more? Would you buy a smaller car than...

The CEO of General Motors, Dan Akerson, told a Detroit newspaper that the Federal tax on gasoline should be raised by 50 cents or $1 a gallon to encourage consumers to buy more fuel efficient vehicles.. In an interview last week with the Detroit News, Akerson said a higher gas tax should be part of...

Unlike other compact cars, the gas-mileage story for the 2011 Hyundai Elantra is simple. There's a single engine, a choice of two transmissions--six-speed automatic or six-speed manual--and any Elantra you order will have the same EPA-rated gas mileage. The figures are 29 mpg city, 40 mpg highway...

We have to admit, we're fond of infographics. This one has three simple parts. It looks at gas prices--which recently rose to an average of $4 a gallon before ebbing slightly--showing national average prices for both three grades of gasoline and for diesel fuel. Then it suggests some driving tips...

With two models--one all about gas mileage, with two transmission options, plus the other one, which has two engines and two transmissions--the 2011 Chevrolet Cruze may take some sorting out if you're looking to maximize your fuel economy. At least there's only one body style for the new 2011...

With a redesigned range of Civic sedan and coupe models, and no fewer than five separate variants, the new 2012 Honda Civic makes an aggressive effort to position Honda at the forefront of gas mileage. Unlike models from other makers, if you order a standard 2012 Civic with the 1.8-liter engine...
