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.

2024 Chevrolet Silverado EV output jumps to 754 hp and 785 lb-ft

A couple of days ago, GMC unleashed its 2024 Sierra EV Denali Edition 1 pickup, the luxury truck division's version of the 2024 Chevrolet Silverado EV. As has been the case between Chevy and GMC for decades, GMC designers worked to put ample visual difference between the two pickups that share the similar underpinnings. Unlike what's been the historical case, GMC announced output figures for the Sierra EV well above those for the Silverado. Preliminary estimates for the battery-electric Sierra with the dual-motor powertrain are 754 horsepower and 785 pound-feet of torque. Chevy revealed the 2024 Silverado EV in January with 664 hp and 785 lb-ft in RST trim. We're not sure what happened after the GMC debut, but the Bowtie has updated the Silverado's output to match the GMC with 754 hp and 785 lb-ft. Chevy truck communications spokesperson Sean Szymkowski submitted a statement to various outlets explaining, "As we prepare for production of the Silverado EV, our engineering team has further refined the estimated performance specs for the 2024 Chevrolet Silverado EV RST First Edition. GM now estimates horsepower to be up to 754 and torque up to an estimated 785 lb-ft when Wide Open Watts mode is engaged." It's possible Chevrolet did so in order to forestall backlash about the disparity, or it's possible the automaker already planned to do so after the GMC dropped. On the ICE side, buyers have got used to powertrain parity, the Silverado and Sierra offering the same engines with the same outputs even with pricing about $3,600 apart on the respective top trims. No matter how the decision was made, the benefits redound to Silverado EV buyers. By the way, the "Wide Open Watts" reference refers to the driving mode required to extract these peak power figures. In the GMC Sierra EV, this is called Max Power Mode. We're still looking for clarity on the output figures in everyday driving modes, we believe those will be the same 510 hp and 615 lb-ft that's the maximum in the lower trim Silverado EV Work Truck.    With a year to wait before the Silverado RST EV reaches reservation holders, and with the Chevrolet Work Truck providing real-world feedback before the RST arrives, don't be surprised at more tweaks made to both the Silverado and Sierra EVs before they hit the market.
