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."

Which of these five plug-ins should win the 2017 Green Car of the Year?

It's going to be a competitive race for the 2017 Green Car Of The Year. With a minivan in the running for the first time in ages, the five finalists announced by Green Car Journal today include five very different plug-in vehicles. As Ron Cogan, the editor and publisher of Green Car Journal, said in a statement, "electrification is now considered by most automakers an essential technology for current and future high-efficiency models." Let's check out the list: Toyota Prius Prime, the updated plug-in version of the world's best-selling hybrid. Chevy Bolt, GM's all-new entry into the long-range EV game. Chrysler Pacifica, a family hauler with the ability to go 30 miles on electric power. Kia Optima. The nomination is for the full line-up, but really the hybrid and plug-in hybrid models are the green stars here. BMW 330e iPerformance, one of the automaker's many new plug-in hybrids that bring battery power to models outside the i sub-brand. Green Car Journal will announce the winners at the Los Angeles Auto Show on November 17th, along with some, "other green transportation announcements," whatever that means. Last year, the winner was the 2016 Chevy Volt, the first model to snatch up two wins. Which do you think should win this year?

Why does Chevy want to trademark Camaro Krypton?

The Chevrolet Camaro and Ford Mustang have the type of long-lived rivalry that is often found in the pages of comic books. Is the Camaro the Kryptonite to the Mustang's Superman, though? We might get to find out soon, if two recent trademark filings are any hints. On May 5, General Motors filed trademarks in the US for both Krypton and Camaro Krypton (not pictured above). While the move seemed potentially timed with the release of Batman v Superman: Dawn of Justice next year, engineer Al Oppenheiser shot that theory down to The Detroit Free Press. "I think that's just Internet buzz, which is great," he said to the newspaper about the alleged connection. "It's another thing about this segment of cars: there's always Internet buzz." Rather than a special edition connected to next the superhero film, Oppenheiser speculated something else. "Sometimes when we come up with a new color in our studios, they just apply [for a trademark] in case we ever use it," he said to The Detroit Free Press. "We never said we're going to do anything with that color." Still, as Superman's home planet and part of the name for the mineral that can harm him, Krypton undoubtedly has a superhero connection. To maintain the link to the comics, such a color would likely be a shade of green. Although, depending on the depiction in the books, the exact hue can vary between bright neon and a darker tone.
