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.

Chevy Silverado edges Ram 1500 in Consumer Reports two-truck shootout

Forget Corvette versus Viper. When it comes to important head-to-head comparisons, fullsize trucks are where domestic automakers really care. And until the redesigned Ford F-150 makes its debut, the Chevrolet Silverado is going to have plenty to brag about thanks to a new Consumer Reports shootout against the Ram 1500.
It was a tight race among these V8-powered titans, but the all-new 2014 Silverado (and its GMC Sierra twin) barely edged out Ram's updated pickup with a score of 81 points - enough to make it the institute's top-rated fullsize truck on the market. Its narrow victory over the Ram, which finished just three points back, was due to its superior fuel economy, better towing and payload capacity and conveniences like a lower step-in height, easy-to-use tailgate and rear bumper steps that make loading and unloading less of a chore.
Importantly, CR notes that buyers with less heavy-duty truck needs might actually prefer the Ram over the Chevrolet, since its high points include a smoother ride thanks to its coil spring rear suspension, dominant infotainment system with Uconnect, and a big thumbs up for the available Hemi engine and eight-speed automatic transmission.

2018 GMC Sierra Denali 1500 Drivers' Notes | Chrome cowboy

No matter how much automakers want to charge for trucks, it seems there will be a market. Ford, Ram and GM all have trucks that can push well over $60,000, something that would sound unbelievable even 10 years ago. That brings us to the 2018 GMC Sierra Denali, GM's top dog in the pseudo-lux truck segment. It's packed with tons of goodies and features, but it's starting to feel a little long in the tooth. Still, GM trucks are some of the best selling vehicles in America, so it seems customers don't mind the age. Associate Editor Reese Counts: I've said it before, but I'm not a big truck guy. Give me a Colorado or Tacoma over any of the full-sized behemoths rolling off assembly lines today. Still, I do enjoy taking one home on occasion, especially one as comfortable and well appointed as this Sierra Denali. There's leather and wood and contrasted stitching throughout. The problem is that it's all a veneer over what's becoming an extremely dated truck, though a new one is on the horizon. There's one big thing that truly bothers me about this truck: no keyless entry or ignition. Don't get me wrong, I have no problem doing things the old-fashioned way, but when literally every other competitor at this price has keyless as standard equipment, the fact that GMC (and Chevy for that matter) still require you to pull out a fob and stick a key into an ignition is really glaring. It has to have something to do with the platform, as GM makes plenty of vehicles that don't require a key. One thing that doesn't feel dated is the ride and performance. This truck is equipped with GM's Magnetic Ride Control, and it works wonders for the Sierra's comfort. It would be even better if it wasn't wearing some gaudy 22-inch wheels, but it's still better than a lot of trucks out there. The powertrain, too, is a nice bright spot. The eight-speed automatic is smooth and never feels lost in the hunt for better fuel economy. The 6.2-liter V8 feels strong, and power comes on smooth and easy. Ford's EcoBoosts may win on fuel economy, but there's nothing like a big, burly V8. Senior Editor, Green, John Beltz Snyder: Despite the massive amounts of guilt I feel every time I put my foot to the accelerator, big trucks — something of which I used to steer well clear — are beginning to warm up on me. That being said, others have made more of an impression on me than this Sierra.
