Fuel Efficiency

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...

To qualify for a $465 government-funded sales subsidy, China will now require automakers to use engines under 1.6 liters and achieving a minimum fuel economy of 37 mpg.

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.

Take a trip to England and at some point you’re likely to sit in the back of a London taxi cab. Just as famous as its New York counterpart, the London taxi cab is known for its tight turning circle, iconic shape and the scores of native Cockney ‘cabbies’ which pilot them. But if...

If you’re an electric car owner who finds that the range you can get from a full charge isn’t anywhere near the distance the dealer claimed, you’re not alone. Rushing to work, carrying excess weight, poor maintenance, inadequate planning and even drive distractions while driving...

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...

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...

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...

Buick announced today that it would price the four-cylinder version of its 2012 Lacrosse large sedan at $29,960. That sneaks the advertised price neatly under the $30,000 mark, although a mandatory $860 destination charge means buyers will see a sticker of at least $30,820 before they start adding...

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...

The 2011 Toyota Prius hybrid gets the best gas mileage rating of any car for sale in the U.S. market today. It's rated at 51 mpg city, 48 mpg highway, for a combined rating of 50 mpg--and that's a number no other car can match. At least, no other car that doesn't plug into the wall for some (2011...
