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 will expand Super Cruise to entire U.S. lineup after 2020

General Motors plans to bring its Super Cruise semi- autonomous highway driving technology to its entire U.S. lineup after it rolls it out to all Cadillac vehicles in 2020. Mark Reuss, GM's executive vice president for global product development, made the announcement at the Intelligent Transportation Society of America conference in Detroit. Automotive News reports he also announced plans to offer vehicle-to-everything (V2X) communication in a high-volume Cadillac crossover by 2023 — technology that will also eventually spread across the luxury brand's portfolio. Super Cruise is GM's semi-autonomous, lane-centering driving system that uses lidar mapping, GPS, cameras and sensors. The system offers hands-free driving on the highway, with an infrared camera and lights that track the driver's head position to make sure the driver is paying attention, ready to take over when needed, and not nodding off. If it senses the driver is unresponsive, it can bring the vehicle to a stop on the shoulder and activate OnStar. Super Cruise is already an option on the 2018 CT6 and standard on the Platinum trim model. You can read our First Drive review of the technology here. Meanwhile, Cadillac launched vehicle-to-vehicle technology in the 2017 CTS sedan, allowing equipped Cadillacs to share information regarding speed, direction and location at distances of up to 980 feet to help avoid collisions. By going one step further with V2X, Cadillac can tip off drivers to hazardous road conditions, the status of traffic lights, work zones and threats of crashes. It's the first major announcement from the luxury brand since the departure of former CEO Johan de Nysschen and his replacement by Steve Carlisle in April.
