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.

2019 Chevy Silverado 1500 vs. 2019 Ram 1500 vs. 2018 Ford F-150: How they compare

The full-size pickup truck market is seriously hot right now. Both Ram and Chevrolet have introduced completely redesigned trucks, the 2019 Ram 1500 and the 2019 Chevy Silverado, and as the companies slowly roll each one out, more and more information comes to light. We've put together this comparison post to help you keep track of all the features and specifications of each of these new models, along with the updated 2018 Ford F-150. Among the stats we'll take a look at are engines, power, fuel economy, trim levels, weight and more. Weight savings Both the 2019 Ram 1500 and 2019 Chevy Silverado 1500 have gone on a diet for the new model year, similar to the one the F-150 went on in 2015. The Silverado is the weight-loss leader, having shed 450 pounds when comparing quad-cab V8 models. The Ram 1500 lost 225 pounds compared to the current truck. Both trucks achieve their weight loss in part due to the use of aluminum parts. On the Silverado, the hood, doors, and tailgate are aluminum, while on the Ram, just the hood and tailgate are aluminum on the body. Compare that to the F-150, which uses aluminum for all exterior body panels for a total weight loss of up to 732 pounds, which makes the aluminum-intensive F-150 the weight-loss leader. View 160 Photos Engines and transmissions There's only a bit of overlap in powertrains on the Ram 1500 and Chevy Silverado. Each has a V8 for the top engine. The Ram's is a 5.7-liter Hemi V8 making 395 horsepower and 410 pound-feet of torque. The Silverado will once again use a 6.2-liter V8 as its range topper with the same 420 horsepower and 460 pound-feet of torque as the current model. Both of these V8s boast some extra fuel saving technology. The Chevy's 6.2-liter (and some 5.3-liters) comes with the company's latest cylinder deactivation system that can shut off any or nearly all of the eight cylinders. The Ram's V8 boasts an optional 48-volt mild-hybrid system that, in addition to likely helping fuel economy, can provide up to 130 pound-feet of torque right off the line. With the Ram, fuel economy sees an improvement of 2 mpg in the city and combined ratings for 17 and 19 respectively. Highway fuel economy improves by 1 mpg to 23 with two-wheel drive and 22 with four-wheel drive. The Silverado's 6.2-liter V8 only improves city fuel economy by 1 mpg to 16, and actually loses 1 mpg on the highway. The new 5.3-liter engine with the fancy cylinder deactivation does see an improvement over the simpler version.

2022 Chevrolet Silverado and GMC Sierra now cost more, again

GM Authority put Chevrolet and GMC pickup truck prices under the microscope, spying the same macroscopic issues none of us can avoid seeing: Price increases. The 2022 Chevy Silverado 1500 and 2022 GMC Sierra 1500 have been hit with their third price increases this year. The Heavy Duty versions of those same trucks have been given their fourth price increases this year. Starting with the light-duty options, they've been rung up for another $900 across the board, which breaks down to $800 added to the MSRP and $100 added to the destination charge. The mandatory cost for shipping a truck from the factory to the dealer is now $1,795. That destination fee is now more than 5% of the purchase price of the least expensive 2022 Silverado, the Regular Cab Work Truck trim with a Standard Bed and 2.7-liter turbocharged four-cylinder retailing for $36,395 after destination. And that price is $3,200 more than the initial list price from last December. At the other end, the Silverado ZR2 is up $3,400. Average that out, and the Silverado's MSRP has gone up by nearly $700 every month since initial pricing came out. On the GMC side, the bidding starts at $37,195 for the Regular Cab Pro trim with a Standard Bed, a $4,700 increase over pricing announced last October.  Stepping up a tow rating or two, the Silverado HD is now $1,100 more expensive — $1,000 tacked onto the MSRP, the destination charge plumped another $100 to $1,795. The Silvy 2500 HD now starts at $41,295. The Sierra HD turns the screw a few more degrees, going up by $2,100 after the $100 increase for destination. The low bar for the Sierra 2500 HD is $41,995, a $4,100 rise over the price when it hit dealer lots last summer. Whew. Anyone know where the exit is for this "new normal?" Related video:
