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 Sierra EV Denali Edition 1 teased before tonight's debut

GMC says its Sierra EV Denali Edition 1 battery-electric pickup is "Built to tower above everything you thought an electric truck could be. That’s why itÂ’s the only EV that deserves the name Denali." We will know what the marketing speak means tomorrow (Thursday), when GM's third electric pickup in a year debuts at 5 p.m. Eastern. GMC teased the face of the Ultium-powered Sierra Denali nearly a year ago with an animated rendering. This second teaser on the eve of the debut gives us a better feel for what to expect. The front fascia advertises the product with illuminated GMC lettering at the center of a grille panel defined by an illuminated border. Upside down L-shaped LED lights frame three LED charging status bars. Below those at the bumper edges are what look like four fog lights, two round units above two squared oval units. In back, a glimpse of taillight reminds one of the Hummer EV's spendy rear lights, a Denali badge informing tailgaters what kind of truck they're following. A panoramic glass panel takes up just about the entire roof, save for some sheetmetal at the back where the shark fin antenna rests. Under that roof, one of the seating options will be a ventilated, quilted fabric with "Denali" embroidered in the headrest.  All the other intel must wait another 24 hours. This truck's Chevrolet Silverado EV sibling has been pitched as pricing between $40,000 and $105,000. We've been told the Sierra EV will only come in Denali trim, so expect the feature set and pricing to align more with the Hummer EV, from close to $100,000 once all trims are rolled out to sums well over $100,000. The furnishings could set a new benchmark in glitz for GMC, brand VP Duncan Aldred saying, "We now have an opportunity to evolve SierraÂ’s capabilities and technologies, as afforded by transitioning to an all-electric propulsion while also elevating the luxurious design and comfort associated with Denali." The playbook established so far leads us to believe the Ultium platform will provide a 200-kWh battery and an estimated range of 400 miles, and an output of something like the 664 horsepower and 780 pound-feet of torque in the top Silverado EV trim. Or this limited Edition 1 trim could split the power gap between the Silverado EV and the 1,000-hp Hummer EV.  Reservations open after the debut.
