GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.

GMC Hummer EV could have had the Chevrolet Avalanche's Midgate

One of the many rumors swirling around the GMC Hummer EV claimed the truck would resurrect the Midgate inaugurated by the original Chevrolet Avalanche. Although we now know there's no way to fully knock down the partition between the cab and the cargo box, the firm revealed the rumor wasn't entirely false. "There was [a Midgate] early on. We opted for the functionality of the drop glass in the back. With the package layout and things like that, it was not advantageous to pursue that one. And, the five-foot bed was kind of the industry standard in regards to price of entry in that segment," explained John Mack, the Hummer's exterior design management, during an interview with Muscle Car & Trucks. The Hummer will go on sale with a five-foot box, and it doesn't sound like a longer bed will be available, so a modern version of the Midgate would have made the model more versatile by giving users the ability to fold down the partition behind the rear seats to carry bulky items, like plywood and ATVs. It's a feature that would have inevitably made the truck more complicated to build, however, because it adds moving parts that need to be sealed. Hinges, seals, and latches in turn add weight, and complexity almost always invites high manufacturing costs. As an electric pickup built with newly-developed components, the Hummer already has enough of each. Motorists who need to carry something that's significantly longer than the cargo box aren't entirely out of luck. As Mack pointed out, the rear window drops into the partition, so owners will have the ability to haul surfboards, lumber, or anything else that's relatively long and reasonably thin by simply pushing a switch. Alternatively, the only thing limiting cargo space when the roof comes off is the sky — or, depending on where you live, bridges. Mack didn't reveal when the Midgate was dropped. GMC launched the Hummer project in April 2019, and it previously released early design sketches that show how the truck transitioned from a sketch to a prototype. As of writing, nothing suggests the Midgate will make a comeback in the near future on any member of the General Motors portfolio. It was introduced in 2001 on the first-generation Chevrolet Avalanche, which went on sale in the United States for the 2002 model year. It later spread to Cadillac's luxed-up variant of the truck, the Escalade EXT, and to the short-lived GMC Envoy XUV.

Truck Trend names GMC Sierra Denali 2016 PTOTY

Citing its best-in-class power, its amenities, and technology, Truck Trend magazine has named the GMC Sierra Denali its 2016 Pickup Truck of the Year. Seven "all-new or significantly revised pickup trucks" were invited to compete, and out of the seven tested categories the Sierra won interior, functionality, and "Empirical," and scored second in highway testing and exterior looks. It beat the Chevrolet Silverado 1500 High Country and Colorado Z71 diesel, GMC Canyon SLT diesel, Nissan Titan XD Pro4X, Ram 1500 Rebel, and Toyota Tacoma TRD Off-Road. In the mag's 43rd annual Four-Wheeler of the Year award, the Range Rover SVR claimed the crown. The Sierra got refreshed this year with new front-end styling with HID headlamps and LED accents, tech features like Apple CarPlay, Android Auto, and wireless phone charging, and optional convenience features like a remote locking tailgate and power articulated assist steps. The big powertrain upgrade was availability of the 5.3- and 6.2-liter V8s with an eight-speed automatic transmission. This is the second time Truck Trend has conferred a PTOTY award, the Ford F-150 walking away with the silverware last year. The nod to the Sierra comes after sister publication Motor Trend named the 2016 Chevy Colorado with the Duramax diesel engine its Truck of the Year.
