The U.S. launch of the 2011 Hyundai Sonata Hybrid has slipped a month, just enough to preclude buyers from taking advantage of a $1,300 Federal tax credit that expires December 31. According to Hyundai, the first cars will now reach dealers in January or perhaps later, rather than in early or mid...

One of the main reasons buyers steered away from the old Ford Explorer sport utility vehicle, according to Ford itself, was its fuel economy. So gas mileage had to be a major selling point for the all-new 2011 Ford Explorer. Like so many new cars and crossovers, the latest model does indeed get...

Just a month ago, we suggested that 40 miles per gallon is the new bragging threshold for subcompact and even compact cars. Now, Hyundai has dropped the gloves (or thrown down the gauntlet) with a clever marketing campaign to contrast it with other makers: It will start breaking out the sales of...

For many years, Honda was routinely awarded the title of greenest carmaker in the U.S. market. But its most recent green cars have stumbled, and a dark-horse competitor is rising fast toward taking the coveted title, conferred every few years by the Union of Concerned Scientists. It's not Nissan...

The shenanigans continue. Just this week the Nissan LEAF was rated at 99 mpg-equivalent by the EPA, raising the ire of our own John Voelcker--and justifiably so. Today, the Volt gets similar treatment and a similar rating, but only in EV mode. Add in the gas-only mode's 37 mpg rating and the...

Sometimes even well-informed industry analysts get it wrong. Or miss the forest for the trees. A recent posting by Pike Research, entlted "Europe Leads, U.S. Lags In Start-Stop Hybrids," correctly notes that adoption of start-stop systems is well advanced in Europe, but lags behind in the U.S. But...

To achieve ambitious 2016 Federal fuel-economy goals, carmakers are working hard to make their engines smaller and more efficient. That's not news. But it's increasingly looking like we'll have a new target for compact cars over the next few years: a rating of 40 miles per gallon highway, from an...

Turbochargers have been with us in volume production only since the Seventies, but superchargers have a long and honorable automotive history. They were used on the Blower Bentleys that won Le Mans 80 years ago, and have appeared ever since on high-performance engines, often larger ones. A boost...

After many months of testing, qualifying, and mechanical challenges--not to mention reams of press releases--today the Progressive Automotive X-Prize announced the winners of its three categories, who will split $10 million in prize money. Both winners in the "alternative" classes for two-passenger...

Reading the news in our automotive world never fails to surprise and delight. Take, for example, our discovery of the soliticitousness exhibited by automakers who care deeply about the delicate and fragile feelings of car buyers. Yes, those same car buyers from whom an independent dealer's job is...

Want to know the fuel economy ratings of a new car you're considering? You probably already know to look at the gas-mileage window sticker. Now, for the first time in 30 years, the U.S. Environmental Protection Agency and the National Highway Traffic Safety Administration are planning a...

It was so much easier just a few short years ago. Luxury cars wafted and sports machines roared, with nary a thought to gasoline consumed. Hybrids were for weenies, and everyone knew their place. But now? A hybrid Ferrari, a hybrid Porsche race car, an electric BMW ... what is the world coming to?...

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...

America loves to complain about gas mileage and the cost of gasoline.  As it turns out, part of the problem is us. A study by the Centers for Disease Control and Prevention found a 1.1 percent increase in self-reported obesity, which translates into extra weight that your vehicle has to haul...

With the 2011 Honda CR-Z headed for dealerships this summer, and the 2010 Honda Insight struggling to make a sales impression, the third of Honda's three new hybrid models is being cued up in Japan. The 2012 Honda Fit Hybrid (which will go on sale in Japan this October as a 2011 model) has now been...

If you're one of the 50 million Americans reached by Ford's marketing today, you'll know by now that the company launched a new 2011 Explorer sport utility. High Gear has covered the 2011 Ford Explorer from pretty much every angle, including our post earlier today on some fuel-saving tricks  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...

It's the Friday before a long holiday, which means most of you aren't around to read this. But for those who are, here's our bit of green-car randomness to launch the Independence Day celebrations. How would you like to own a semi-derelict, half-century-old, very odd-looking German car that holds a...

Like many site editors, we read our traffic stats religiously. Perhaps unlike other site editors, ours frequently make us laugh. We try to provide practical information on navigating your way through the confusing claims made about 'green' cars, whether they're hybrids, clean diesels, or just very...
