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.

Jay Leno welcomes a 2016 Cadillac CTS-V into the garage

After checking out a multitude of classic cars and customs over the past few weeks, Jay Leno switches things up with a modern performance machine in the latest video from the garage – a 2016 Cadillac CTS-V. Leno is curious about Caddy's attempt to challenge the BMW M5 and Mercedes-Benz E63 AMG S, and he takes a long, technical look at the sedan with chief engineer David Leone. Not content to just peek under the hood, Leno puts the CTS-V up on the rack to see what it packs underneath the svelte body. Once he gets the lowdown on the Caddy's engineering, it's time for a drive. Leno also flexes his interviewing skills while behind the wheel and gets even more info about the CTS-V's capabilities from Leone. He seems fairly impressed, but Leno's most entertaining question about the 640-horsepower sedan is whether it can do a burnout. He provides a definitive answer to that at the end of the clip.

Junkyard Gem: 1973 Cadillac Eldorado

The 1971-1978 Cadillac Eldorado was a gloriously ridiculous personal luxury coupe, packing a monstrous 500-cubic-inch V8 (that's 8.2 liters for you freedom-hating metric types) under its acre-sized hood for the first five years of production. Fuel economy was comfortably into single-digit territory, which meant you had to be a real high roller to be able to feed a new Eldo after OPEC turned off the oil spigot. I found this '73 in a Denver wrecking yard earlier this spring. View 18 Photos This car appears to have been sold new in Denver, and the extensive bodywork and sanded areas indicate that it was someone's project car prior to coming to the end of the line. The front-wheel-drive system used in the Cadillac Eldorados and Oldsmobile Toronados of this era was known as the Unified Powerplant Package, and it used a longitudinally-mounted engine feeding a chain-drive setup that proved to be amazingly sturdy and reliable. So sturdy, in fact, that it was used in gigantic front-wheel-drive GMC motorhomes. Everyone agrees that these cars are cool, but few are willing to rescue a rough example and take on the difficult and expensive job of a full restoration. This one isn't rusty, but that wasn't enough to save it. Related Video:
