Following its October approval of E15 gasoline for 2007 or newer cars, the U.S. Environmental Protection Agency is to announce today that it will expand the approval to cars from the 2001 through 2006 model year as well. E15 contains 15 percent ethanol, half again as high as the legal maximum today...

With all the hoopla surrounding this week’s 2011 Detroit Auto Show, we’re quite surprised to learn that Chrysler has yet another major announcement to make, this time together with the Environmental Protection Agency. The two groups are set to announce a new research and development...

Some of the first emissions regulations in the world came about because of the way the Los Angeles Basin is shaped. Reports of smog in southern California started with the Conquistadors, and by the Sixties, LA was notorious for its foul air. California began regulating auto emissions before the...

If the idea of measuring the efficiency of an electric car, which burns no gasoline, in miles per gallon still irks you, spare a thought for our green car expert John Voelcker who goes to some length in this previous article to try and explain why the EPA deems it fit to do so. While that previous...

Start-stop systems, which shut off car engines when the vehicle comes to a stop, have been offered in Europe for several years. But until now, no automaker other than Porsche has offered them on U.S.-market cars. That's about to change. Ford said yesterday it will offer the systems on some of its...

Today's small cars are better than they've ever been, even if few of them are among the EPA's all-time gas mileage champs. And spurred by tighter fuel-economy laws, 40 miles per gallon on the highway is becoming the new target for subcompact and even compact cars. There's just one little problem...

Every now and then, readers write to grumble about new cars and their gas mileage. The gist is usually something like this: You wrote that the new 2011 [Make & Model] gets 40 mpg highway? Well, big whoop-de-doo. I always got at least 45 mpg in my 1992 Geo Metro, and it was a whole lot cheaper...

Compact cars are pretty much a known quantity, and hence easy to visualize. Many are headed for 40-mpg highway ratings, and Hyundai recently threw down the gauntlet in saying it would start to report sales of 40-mpg vehicles--and challenged other makers to do the same. Imagine a compact car,and...

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...

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...

So it's come down to this, has it? The U.S. car-buying public is apparently so stupid that the Environmental Protection Agency has to rate the efficiency of an all-electric car that burns no gasoline in ... miles per gallon. [facepalm] That's the only possible reaction to the news this afternoon...

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...

GM has managed to deliver on its promise of segment-leading fuel economy for its new 2011 Chevrolet Cruze Eco model, with the EPA announcing this week that the fuel efficient sedan will return 28 mpg in the city and up to 42 mpg on the highway when equipped with a manual transmission. The numbers...

Well, now we know the numbers. And there are a lot of them. The U.S. Environmental Protection Agency and Department of Transportation jointly proposed cutting greenhouse-gas emissions from medium and heavy duty trucks by 10 to 20 percent, starting in 2014 and extending through 2018. (The actual...

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...

Whether it's the rather bland styling or the underwhelming stats, the 2011 Lexus CT 200h hasn't achieved much in creating buzz in the headlines. In fairness, hybrid power, low emissions and claims of high fuel efficiency don’t mean much without the all important EPA-rated fuel economy figures...

With electricity not always generated through renewable methods, it can be hard to claim that an EV is truly zero-emissions. It's generally accepted that you aren't pumping any gasses out the back as you drive along, though. Well, the car shouldn't be anyway... Despite this, electric vehicle...

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...

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...
