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.

Recharge Wrap-up: EV torque secrets, UC Davis maps future of biofuels

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellulosic and algae-based biofuels. The paper suggests ways the US could use these three routes together in different areas, and predicts the payoffs in terms of carbon emissions could be significant if the right people are willing to risk the capital. After all, financial advisers are always telling investors to diversify their portfolios to manage risk and rewards in the same way.

The seventh round of the inaugural all-electric race season, which was moved from Los Angeles to the streets of Long Beach, will offer fans free grandstand and general admission. The race, which takes place on April 5, 2015, will use a 1.6-mile portion of IndyCar's Grand Prix of Long Beach. Read more at LA Times. Polaris is now offering its 2015 GEM electric vehicles, including the new street-legal eM1400 LSV. The passenger and utility vehicles come in two- to six-passenger configurations, many of which are street legal on roads with posted speed limits of up to 35 miles per hour. The eM1400 LSV utility vehicle seats two, offers 1,250 pounds of payload, 1,250 pounds of towing capacity, a top speed of 25 mph and a range of up to 45 miles. Its on-board charger plugs into any standard 110-volt outlet. Read more at Hybrid Cars and check out all the different configurations yourself at the Polaris website. In EVs, more torque does not always equal faster. Green Car Reports found this out when driving the Fiat 500e (with 147 pound-feet) against the similarly weighted Chevrolet Spark EV (with 400 pound-feet). The secret is, at least in part, in the gearing. The Fiat has a 9.6:1 reduction gear, making it quicker at lower speeds despite having far less available torque, while the Chevy uses a 3:1 ratio. The trade-off though, is in top speed. Furthermore, Chevy electronically limits the torque delivery at low speeds, as 400 pound-feet is a lot of launch for the little Spark EV to handle.

2016 Chevy Colorado Duramax makes 369 lb-ft for $3,730 premium

Since announcing the new Chevrolet Colorado in late 2013, there has been absolutely no secret that the 2.8-liter Duramax diesel would wind up under the hood of the midsize pickup truck for the 2016 model year. It has been a long wait for those wanting the oil-burner, but thankfully, the anticipation is nearly at an end. Chevy is finally officially unleashing details about the four-cylinder, which churns out 181 horsepower and 369 pound-feet of torque. The diesel is available in both LT and Z71 Crew Cab trims, and there's the choice of two- or four-wheel drive. All come with a six-speed automatic gearbox with a standard automatic-locking rear differential. An electronically controlled two-speed transfer case comes on four-wheel drive models, as well. The Z82 trailering package also arrives on all of the Duramax pickups and includes an exclusive integrated trailer brake controller. The first shipment of diesels arrives at dealers this fall with a price of $3,730 on top of a comparably equipped version with the 3.6-liter V6. Customers opting for the Duramax are getting more capability from the Colorado. With a 7,700-pound tow rating on two-wheel drive examples (7,600 pounds with four-wheel drive), drivers can haul 600-700 pounds more behind the truck than its petrol V6 counterpart. Fuel economy numbers haven't been announced yet, but are expected to top the gasoline versions. The engine is also B20 bio-diesel compatible. Beyond being just a good hauler, Chevy is throwing cutting-edge tech into these models. For example, this is the company's first application of a Centrifugal Pendulum Vibration Absorber on the transmission's torque converter. The device is a dampener that cancels out torsional vibration from the engine for a more comfortable ride for occupants. There's also a driver selectable exhaust brake system that uses engine compression to help slow down the truck and reduce brake wear.
