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.

2015 Chevrolet SS Review [w/video]

The Chevrolet SS is one of the best cars no one's buying. It's a Bowtie-badged version of the Australian Holden Commodore with a 6.2-liter LS3 V8 under the hood. It's got a six-speed manual transmission, General Motors' sophisticated Magnetic Ride Control suspension, and rear-wheel drive. It's a fullsize sedan that comes with every possible amenity you could want. And it's less than $50,000. Chevrolet sold 2,479 SS sedans in 2014. That means it was outsold by every other vehicle the automaker offers, even the police fleet-only Caprice. (I'm only talking about cars that were on sale for the full 2014 calendar year, of course.) The aforementioned manual transmission and MRC suspension were added for 2015, but it's not clear if that's helping. The SS is down 7.7 percent through June of this year, compared to 2014's numbers. But hey, at least it's finally outselling the Caprice. What a damn shame. Granted, GM only planned to sell a few thousand of these each year, but as enthusiasts, this a car we should be gobbling up. It's the closest we'll get to a four-door Corvette, and with the 2015 model year updates, that statement is more true than ever. People often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Aside from the manual gearbox and magnetorheological suspension, the SS is largely unchanged through its year and a half of sales. But that's no bad thing – we were thoroughly impressed with the SS when we first tested it at the end of 2013. Outside, the SS looks the same, which is a bummer. It is not an attractive car, and the chrome brightwork on the side vents and wheels doesn't help. That said, the sedate styling puts it under the radar – more so than competitors like a Dodge Charger 392, anyway. But maybe it's too under the radar. Even in the new, "Some Like It Hot Red" color (yes, really), photographer Drew Phillips reports that people often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Exterior styling is our only gripe with the SS. Moving inside, there's a lot to like. This is easily one of Chevy's nicest, well thought-out interiors (thanks, Holden), with premium materials and tons of equipment. The Chevy MyLink infotainment system carries over, and now features 4G LTE and wifi connectivity. The touchscreen is a bit slow to respond, but otherwise, it's bright, well organized, and packed with functionality. This is easily one of Chevy's nicest, well thought-out interiors.

Hybrid, Plug-in Hybrid and EV Buyer's Guide: Which one do you want?

If you're shopping for a new vehicle these days, there's a litany of acronyms, buzzwords, and technobabble to further complicate an already difficult decision. But if you're looking at a green powertrain, you have three basic choices to compare: hybrid, plug-in hybrid and "EV" or, electric vehicle. So what are they and which one — if any — is right for you? Research your next new vehicle using Autoblog's Car Finder. Gasoline-Electric Hybrids By now, most people are familiar with the concept of a hybrid car. Thank Toyota's Prius for that. At its most basic, a hybrid vehicle has two powertrains, one gasoline and one electric, which work together for maximum efficiency. At low speeds, the engine can shut off entirely, relying solely on the battery for propulsion. The battery is either charged as you drive by converting kinetic energy into potential energy via a complex regenerative braking system, or directly off of the gas motor. This is a very hands-off, behind-the-scenes system as all the driver has to is put in gas and drive as normal. Hybrids come in all shapes and sizes and, according to the EPA, range in fuel economy from 58 mpg for the Hyundai Ioniq Blue all the way down to 13 mpg for the Ferrari LaFerrari Aperta. Best For: Anyone who want to see their fuel consumption go down without many sacrifices. You can easily find a hybrid sedan, hatchback, crossover, SUV or even a pickup truck (i f you can find one). Best of all, a hybrid requires no special equipment to be installed at home, or added work for the driver. Hybrids do cost more than traditionally-powered competitors, so make sure to compare projected fuel savings with how much extra a hybrid will cost – it may take a surprisingly long time to break even. The EPA provides a handy calculator for this very purpose. Our Favorite Hybrids: 2017 Toyota Prius 2018 Hyundai Ioniq Hybrid 2017 Ford Fusion Hybrid Plug-In Hybrids Sometimes referred to as a PHEV, or plug-in hybrid electric vehicle, this is a baby-step towards full electrification. Armed with a much larger battery pack than a hybrid, PHEVs can go between 12 ( Mercedes-Benz GLE550e) and 97 ( BMW i3 w/Range Extender) miles on electricity alone depending on the model and your driving style. Like a normal hybrid, the driver is largely unaware of which power source is currently in use, even as they switch over — either because the battery is drained, or the driving circumstances require more power.
