Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.

Four recreational vehicle companies in Texas have settled with the EPA over illegal import and sale of off-road vehicles. The 4,000-plus Hammerhead brand vehicles in question were imported without the proper certification, a violation of the Clean Air Act. Some vehicles lacked proper emission control equipment or were manufactured by a company not listed on the certificate application. The settlement totals $560,000 in civil penalties for the companies involved. Read more from the EPA. The Iowa Supreme Court has upheld the state's natural gas tax, which was challenged by the ethanol industry. Ethanol producers, which use natural gas to make ethanol, argued the complicated tax was unconstitutional, as it forced certain plants to pay more than their competitors. Taxes vary by location, and some plants have to tap into interstate pipelines at much higher tax rates rather than get it from a local utility. Now, ethanol producers will work to change the law. "My hope is that people understand that, something may be constitutional but that doesn't make it good public policy," says Iowa Renewable Fuels Association Executive Director Monte Shaw.

Valeo says Audi will launch a vehicle using its electric supercharger next year, with other reports suggesting that car will be the Audi Q7. The company says other unspecified automakers will also use the technology in their vehicles. While the electric supercharger adds to the vehicle's cost and electric energy use, it can improve fuel economy by as much as 20 percent. Read more at Automotive News Europe.

2014 Corvette Stingray meets Tesla Model S in drag strip showdown

They come from two different worlds and have little in common. The Tesla Model S P85 is the sportiest version of this paradigm-punching sedan from California, while the 2014 Corvette Stingray Z51 is a performance-enhanced version of Michigan's recently-updated sports car stalwart. The West Coast car seats five adults and eats electrons like Popeye eats spinach, the Easterner has two passenger places and, surprisingly, sips gasoline like one might bourbon. An attribute they do happen to share is extreme quickness. This similarity is all the excuse Drag Times needed to set the vehicles beside each other at the Palm Beach International Raceway for a bit of mano-a-mano quarter-mile combat. Fortunately enough, cameras were rolling for each of two bouts down the blacktop and the results recorded for our edification and enlightenment. The winner? We won't spoil it for you, but let's just say it's really, really close. How close? Scroll below and watch the video for yourself. Just be warned, the results may surprise you.
