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.

New Corvette Feature Keeps An Eye On Valets

Face it. If you own a luxury or sports car, whenever you hand the keys to a valet, you imagine the car going on a high-speed joyride like the Ferrari in the 1980s cult movie "Ferris Bueller's Day Off." Now, General Motors has an option on the 2015 Chevrolet Corvette that takes those worries away. The latest version of the sports car, due out in September, has a feature that records where the car goes with a camera mounted in the windshield trim. It also captures audio in the cabin as well as speed, engine revolutions per minute, gear position and G-force. That all helps the car tattle on any valet who doesn't take a slow, direct route to a parking space. GM says it's the most extensive attempt by an automaker to thwart valet joyriders, although it's not the first. The automotive website Edmunds.com says Hyundai and Mercedes offer "geofencing," a feature that sets a perimeter and then notifies the owner's smart phone if a car goes beyond it. Chrysler has a valet mode that caps engine speed and horsepower, while Audi lets owners limit engine speed for valets. With the Corvette, once the owner activates the feature with a four-digit code, the touch screen tells the driver it's in Valet Mode. But it doesn't warn the valet that he's being recorded. The feature also locks the glove box and a storage compartment in the dashboard and shuts down the infotainment system. Valet Mode started off as a performance data recorder for those who take their Corvettes on the racetrack. GM engineers quickly figured out that it had more uses. "Think of it as a baby monitor for your car," Corvette Product Manager Harlan Charles said in a statement. "Anyone who has felt apprehension about handing over their keys will appreciate the peace of mind of knowing exactly what happened while their baby was out of sight." Data and video from the valet mode can be viewed instantly by the owner on the car's 8-inch color screen when the car is parked, or it can be downloaded to a computer. The system could go into more mainstream models if feedback is good on the Corvette, GM spokesman Monte Doran said. The feature is paired with a navigation system and costs $1,795. A 2015 Corvette starts at just under $54,000. Chevrolet Technology Gadgets

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.
