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 patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Which electric cars can charge at a Tesla Supercharger?

The difference between Tesla charging and non-Tesla charging. Electrify America; Tesla Tesla's advantage has long been its charging technology and Supercharger network. Now, more and more automakers are switching to Tesla's charging tech. But there are a few things non-Tesla drivers need to know about charging at a Tesla station. A lot has hit the news cycle in recent months with regard to electric car drivers and where they can and can't plug in. The key factor in all of that? Whether automakers switched to Tesla's charging standard. More car companies are shifting to Tesla's charging tech in the hopes of boosting their customers' confidence in going electric.  Here's what it boils down to: If you currently drive a Tesla, you can keep charging at Tesla charging locations, which use the company's North American Charging Standard (NACS), which has long served it well. The chargers are thinner, more lightweight and easier to wrangle than other brands.  If you currently drive a non-Tesla EV, you have to charge at a non-Tesla charging station like that of Electrify America or EVgo — which use the Combined Charging System (CCS) — unless you stumble upon a Tesla charger already equipped with the Magic Dock adapter. For years, CCS tech dominated EVs from everyone but Tesla.  Starting next year, if you drive a non-Tesla EV (from the automakers that have announced they'll make the switch), you'll be able to charge at all Supercharger locations with an adapter. And by 2025, EVs from some automakers won't even need an adaptor.  Here's how to charge up, depending on which EV you have:  Ford 2021 Ford Mustang Mach-E. Tim Levin/Insider Ford was the earliest traditional automaker to team up with Tesla for its charging tech. Current Ford EV owners — those driving a Ford electric vehicle already fitted with a CCS port — will be able to use a Tesla-developed adapter to access Tesla Superchargers starting in the spring. That means that, if you own a Mustang Mach-E or Ford F-150 Lightning, you will need the adapter in order to use a Tesla station come 2024. But Ford will equip its future EVs with the NACS port starting in 2025 — eliminating the need for any adapter. Owners of new Ford EVs will be able to pull into a Supercharger station and juice up, no problem. General Motors Cadillac Lyriq. Cadillac GM will also allow its EV drivers to plug into Tesla stations.
