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."

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

Bring back the Bronco! Trademarks we hope are actually (someday) future car names

Trademark filings are the tea leaves of the auto industry. Read them carefully – and interpret them correctly – and you might be previewing an automaker's future product plans. Yes, they're routinely filed to maintain the rights to an iconic name. And sometimes they're only for toys and clothing. But not always. Sometimes, the truth is right in front of us. The trademark is required because a company actually wants to use the name on a new car. With that in mind, here's a list of intriguing trademark filings we want to see go from paperwork to production reality. Trademark: Bronco Company: Ford Previous Use: The Bronco was a long-running SUV that lived from 1966-1996. It's one of America's original SUVs and was responsible for the increased popularity of the segment. Still, it's best known as O.J. Simpson's would-be getaway car. We think: The Bronco was an icon. Everyone seems to want a Wrangler-fighter – Ford used to have a good one. Enough time has passed that the O.J. police chase isn't the immediate image conjured by the Bronco anymore. Even if we're doing a wish list in no particular order, the Bronco still finds its way to the top. For now (unfortunately), it's just federal paperwork. Rumors on this one can get especially heated. The official word from a Ford spokesman is: "Companies renew trademark filings to maintain ownership and control of the mark, even if it is not currently used. Ford values the iconic Bronco name and history." Trademarks: Aviator, AV8R Company: Ford Previous Use: The Aviator was one of the shortest-run Lincolns ever, lasting for the 2003-2005 model years. It never found the sales success of the Ford Explorer, with which it shared a platform. We Think: The Aviator name no longer fits with Lincoln's naming nomenclature. Too bad, it's better than any other name Lincoln currently uses, save for its former big brother, the Navigator. Perhaps we're barking up the wrong tree, though. Ford has made several customized, aviation themed-Mustangs in the past, including one called the Mustang AV8R in 2008, which had cues from the US Air Force's F-22 Raptor fighter jet. It sold for $500,000 at auction, and the glass roof – which is reminiscent of a fighter jet cockpit – helped Ford popularize the feature. Trademark: EcoBeast Company: Ford Previous Use: None by major carmakers.
