GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

Has Chevrolet gotten the formula right with the Malibu?

Since the Malibu's return in 1997, there has been an internal issue with Chevrolet with getting the midsize sedan formula right in its own way. Let's be frank, the Malibu had a boring beginning as a midsize sedan in 1997. We got the dreadful sixth-generation Malibu in 2004 that brought us an SS model that really didn't deserve the SS badge on it. Hell, its saving grace was fleet sales. But the tides seemed to shift when the seventh-generation Malibu came on the scene in 2008. With the determination of making the Malibu more competitive with other cars in its class, a lot of hard work and effort was put into making the seventh-generation Malibu a timeless and well-crafted vehicle. As an owner of a 2012 Malibu 1LTZ, I have to say that Chevy has fully accomplished it. I love the nicely designed exterior, the interior was comfy enough for those long trips to work each and every day, and it was a very quiet car in my opinion. And its fuel economy was decent, not too bad. The New York Times in 2008 referred to it as "A super Accord, but from GM." In some comparisons, the Malibu was ranked higher than the Honda Accord and the Nissan Altima. It also received the North American Car of the Year award. Love it or hate it, the seventh-gen Malibu was an overall big success for GM. But then in 2013 we got the eighth-generation Malibu. GM gave it a botched release, releasing an Eco model first (that was later discontinued), then later in the year GM released the regular Malibu models. Shifting to a new platform didn't help it either. Even though it separated it further from the Impala, which was built on the same platform as the last-gen Malibu, the shrinkage in legroom, its OK design language, and a poorly crafted interior helped contribute to its overall lackluster sales performance. Not to mention the cars in its class got 10x better than the Malibu as well. Just 18 months after the 2013 Malibu went on sale it received a mild refresh to try to help its OK design, but it didn't help at all. The fate of the eighth-gen Malibu was sealed early on. But wait, a new light came from GM early last year. It came in the form of the ninth-generation Malibu. I have to say, when the curtain came off of it last year, a huge sigh of relief came from me. To me it seemed that Chevrolet took that determination it had in crafting the seventh-gen Malibu and increased it this time around.

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.
