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.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

2020 Ford Explorer ST vs 2019 Dodge Durango SRT: How they compare on paper

For a few years now, the Dodge Durango SRT has been the sole three-row performance crossover from a non-luxury brand. That all changes now that the 2020 Ford Explorer ST is coming to market. Now we have two family crossovers with rear-drive-based platforms vying for buyers that demand practicality and power. As such, there's no better time to dig into their specs to see how they compare. We'll check out each crossover's horsepower, torque, space, capability and prices. The full specs are listed below, followed by some analysis afterward. We also compared the regular 2020 Explorer models to other crossovers in this segment, if if that's not enough, you can check out our car comparison tool. Performance The Explorer and Durango go about making power in very different ways. The Explorer goes the force-fed route with two turbos feeding a 3.0-liter V6, while the Durango's enormous 6.4-liter V8 produces power with air flow au natural. Of the two, the Durango has the greater output of 475 ponies and 470 pound-feet of torque, feeding the flames of everyone that lives by the phrase "There's no replacement for displacement." The Explorer is no slouch at 400 horsepower and 415 pound-feet of torque, though. Performance isn't purely based on power, though. Other factors play a role, such as weight, and in that regard, the Explorer is way ahead. At 4,701 pounds, it weighs a massive 809 pounds less than the portly Durango. This also means that both crossovers are very close in weight-to-power ratio, with the Explorer only slightly worse at 11.75 pounds per horsepower and the Durango at 11.6. Less weight will also play a roll in handling, and the Explorer is likely to feel sprightlier without so much mass to shift back and forth. Semi-related to handling are tire sizes. The Durango features 295-mm wide tires on 20-inch wheels. The Explorer has 255-mm wide tires on 20-inch wheels, but 21-inch wheels with 275-mm tires are available. So the Durango is working with more contact patch, but as we mentioned, it's carrying a lot more weight. 2020 Ford Explorer ST View 20 Photos Interior Space and Practicality Although the Durango SRT is the largest on the outside in every dimension, it loses out to Explorer repeatedly inside. The Ford has more headroom, leg room and shoulder room in nearly every row except the third-row where headroom comes up a bit short.
