If you were to stroll into your nearestChevrolet
, or Ramdealership
, 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 theEnvironmental Protection Agency
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 turbochargeddiesel
engines – between one another, and between smaller, gasoline-fueled trucks.Consumer Reports
doesn't think it should be this way, and it'sspearheading an effort
(PDF link) to get the government to require manufacturers to publish fuel economy estimates.
Inits own testing
, CR found that heavy-duty pickups powered by Ford's Power Stroke,GM's
Duramax, and FCA'sCummins
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 byConsumer Reports
might be interesting to potential buyers.Click here
