Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."

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.

2022 Genesis GV70, raging at VW ID.4 tech and thoughts on a new Lexus LFA | Autoblog Podcast #696

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick. This week, they talk about driving the Genesis GV70, VW ID.4 and VW Taos. They talk about ways Chevy could "fix" the Camaro. James ranked all the James Bond films based solely on their starring cars. Next, they reach in the mailbag and discuss the question, "Do you think Lexus will make a successor to the LFA and, if so, what do you guys think it would be like?" After ruminating on that query, they dip into the mailbag a second time to recommend a sporty crossover to a listener in this week's Spend My Money segment.
