GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

GMC Terrain Nightfall Edition is murdered-out for the masses

We've lost track of how many special edition Chevrolet Silverado and GMC Sierra pickups there have been over the past few years. But while some special editions can be kitschy, there's nothing overtly bad about the GMC's Nightfall line. We've already seen the blacked-out look on Canyon Nightfall and Sierra All Terrain X pickups, and now, it's being applied to the Terrain. As with the trucks, the Terrain Nightfall's changes are simple: the chrome-heavy finish is replaced with gloss-black accents where applicable. That's what you'll find on the grille surround, the front and rear fascia accents, the license-plate surround, mirror caps, and roof rack. Like Jay Z said, all black everything. Except for the wheels, of course – those have machined faces with black spokes. The grille inserts aren't strictly black either (they're charcoal), and as counterintuitive as it may seem, owners can choose from three body paints in addition to Onyx Black (Summit White, Graphite Gray, and Crimson Red). The Terrain Nightfall Edition will be offered on the SLE-2 and SLT trims, with prices to be announced closer to its fall 2016 on-sale date. GMC Introduces 2017 Terrain Nightfall Edition The News Ahead of its debut at the New York International Auto Show, GMC today introduced the 2017 GMC Terrain Nightfall Edition – a stylized special edition combining blacked-out exterior details and wheels, with popular technologies such as IntelliLink with available 4G LTE connectivity and Wi-Fi hotspot. It joins the Canyon Nightfall Edition and the all-new Sierra All Terrain X as the latest GMC vehicle to offer an exclusive, personalized appearance with the Terrain's premium features and refinement. Product Details The Terrain Nightfall offers an edgy appearance with 18-inch machine-faced aluminum wheels and gloss black spokes, a charcoal grill with a gloss black surround and accents, gloss black front and rear fascia accents, gloss black rear license plate surround trim, gloss black outside mirrors and black luggage rails. Terrain Nightfall Edition will be offered on SLE-2 and SLT models with four exterior color options: Summit White, Onyx Black, Graphite Gray Metallic and Crimson Red Metallic. On Sale Fall 2016 Quotable "Building on its best year ever, Terrain continues to attract new and style-conscious customers to GMC," said Duncan Aldred, vice president of GMC Sales and Marketing.

What the electric Hummer's size and weight means for its efficiency

The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a huge electric Hummer, think again.  The GMC Hummer EV uses significantly more electricity than other EVs, meaning it produces more pollution upstream.  The electric Hummer weighs 9,000 pounds and its battery weighs as much as a Honda Civic. The new electric Hummer rolls through town without a deafening engine rumble or a cloud of toxic fumes, but it doesn't exactly tread lightly.  The colossal truck weighs an astonishing 9,000 pounds. (Think two Toyota Tacomas, three Honda Civics, or 24 Shaquille O'Neals.) Moreover, the GMC Hummer EV is in many ways a supersized gas guzzler for a new era. It repackages many of the same flaws of hulking SUVs and trucks of years past — and proves not all zero-emission cars are created equal. EVs can be energy guzzlers too On the whole, electric cars use less energy than gas-powered ones. But they aren't all equally efficient.  No surprise here: The Hummer needs more electricity than any other EV on the market to move its elephantine frame. The Environmental Protection Agency rates the pickup at 47 MPGe (miles per gallon of gasoline-equivalent). For comparison, the Tesla Model 3 sedan is nearly three times as efficient, earning a rating of 132 MPGe. The Ford F-150 Lightning, another electric truck, gets 70 MPGe.  This has real consequences: Since the US gets 61% of its energy from oil, coal, and natural gas, the more electricity a car needs, the more pollution it creates upstream.  As the Union of Concerned Scientists put it: "Both EV cars and trucks are much cleaner than their gasoline counterparts, but electric trucks are responsible for more global warming emissions than electric cars simply because trucks are larger and heavier."  The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider The Hummer EV is also resource-intensive to manufacture, requiring a ginormous (and weighty) battery to give people the 300-plus miles of range they desire. You could produce three Chevrolet Bolts with the same battery cells consumed by one Hummer.
