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.

GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

GM puts 3 million miles on hydrogen fuel cell test fleet

Have General Motors' hydrogen fuel-cell vehicles emitted enough water vapor over the past six-plus years to equal the steam coming out of Old Faithful? Not exactly, but GM has released a few figures related to the Project Driveway initiative it began in 2007. The numbers are impressive, if not quite of the geyser-spouting variety. In all, the General converted 119 Chevrolet Equinox SUVs to run on hydrogen, and those vehicles have just collectively surpassed the 3 million mile mark. And if you were waiting for us to tell you that the distance equals a half-dozen round trips between the earth and the moon, well, there you go. The better news is that the SUVs have combined to save almost 158,000 gallons worth of gas, and some of the vehicles have more than 120,000 miles on them. More than 5,000 drivers have participated in the project. GM reached that landmark about 10 months after it announced that it was working with Honda to accelerate the development of hydrogen fuel-cell powertrain technology. The two companies estimated last summer that it may have something to sell to the public as soon as 2020. For now, you can check out General Motors' press release below. GM Fuel Cell Fleet Tops 3 Million Miles Chevrolet Equinox fuel cell vehicles driven in real world reach milestone DETROIT – General Motors' fleet of fuel cell vehicles recently passed 3 million miles of hydrogen-powered, real-world driving. Some individual vehicles have accumulated more than 120,000 miles. By GM's estimate, using hydrogen to power these vehicles, the fleet has avoided 157,894 gallons of gasoline consumption. This specially equipped fleet of Chevrolet Equinox Fuel Cell vehicles are part of GM's 119-vehicle Project Driveway program, which launched in 2007. Since then, more than 5,000 drivers have provided feedback on the functionality and drivability of fuel cell technology. "Hydrogen fuel cell technology is an important part of GM's advanced propulsion portfolio and we continue to make substantial progress in furthering this technology," said Charlie Freese, executive director of GM's global fuel cell engineering activities. "These vehicles have operated through seven full winters and a wide range of environmental conditions, proving that fuel cells can meet the demands of real-world drivers." Last year, GM announced two fuel cell-related collaborations.
