Gas Mileage
-
It's Friday, so we're straying slightly afield from covering cars. In this case, we're turning our green lens toward jetliners to look at fuel economy in the sky. Anyone who travels on a jet more than once has likely more than doubled their non-flying carbon footprint, and there are unlikely to be electric jets in our lifetimes. So fuel efficiency takes on great importance in the skies, not only for environmental reasons but because it's a huge expense for airlines over which they have almost no price control. While new technologies are being launched--including diesel aircraft engines and...

How It Works: The Plug-In Ford That Isn't A Hybrid or An EV
For the Friday files, some cool new technology: How about a car that plugs in, but doesn't use that electricity to power the car? Nope, we're not talking about battery electric cars like the 2011 Nissan Leaf. Or range-extended EVs like the 2011 Chevrolet Volt. Or even conventional hybrids adapted...

Cities Want High-Mileage Hybrid Taxis; Judge Says It's Illegal

Remember the 2011 Chevrolet Volt's 230-MPG Claim? Forget It.
Almost a year ago, General Motors launched a little marketing campaign connecting its 2011 Chevrolet Volt range-extended electric car to the figure "230 mpg." As we pointed out at the time, they were basing that projection on a proposed formula for fuel usage patterns that made a lot of assumptions...

More than a year ago, we wrote an article pointing out the flaws in the U.S. practice of measuring a car's gasoline use with the familiar miles-per-gallon (MPG) measure. Now, no less a body than the august National Research Council has agreed with us. As it noted in a pre-publication summary released by the National Academy of Sciences: Fuel economy data cause consumers to undervalue small increases (1-4 mpg) in fuel economy for vehicles in the 15-30 mpg range. Display consumption as well as MPG Its panel strongly urged that the information should be displayed to consumers as fuel consumed...

How Many Million Priuses Would Offset the Gulf Oil Spill?
One million gallons a day is a lot of oil. According to estimates late last week, that could be the daily rate of oil escaping from the Deepwater Horizon well in the Gulf of Mexico. To put that number in perspective, we decided to look at what it would take to compensate just for the lost gasoline...

You'll Save Money With Higher-MPG Cars, But It'll Cost You
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 powertrains must be warrantied in some states for 10 years and 150,000 miles. Their mileage will vary depending on your "duty cycle." Hybrids are at their most fuel efficient in lower-speed and stop-and-go traffic, when their ability to switch off the engine on stops and run short distances solely on...

Hybrids Are For Soldiers Too, Not Just Elite Effete Eco-Wimps
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...

Long-Haul Truckers Beg For Rescue From Nasty Gas-Saving EPA
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 more economical line of direct-injected aluminum small-block V-8 engines for future pickup trucks. Those pickup trucks remain GM's highest-volume single vehicle line, and are very profitable. And the Chevrolet Silverado and GMC Sierra are likely to be outfitted with V-8s for many years to come, so...
