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."

2021 Cadillac CT5-V makes a few changes for its second year

An order guide for the 2021 Cadillac CT5-V reveals a number of small changes to the sedan's formula going into its second year on the market. Starting with the superficial, the $1,225 Red Obsession Tintcoat exterior color and the $625 CT5-V-exclusive Royal Spice Metallic depart after this model year. They'll be replaced by Infrared Tintcoat and another color exclusive to this model called Rift Metallic. Since all but Summit White and Black Raven are cost-option Premium hues, the new colors should be expected to add to the price. Materially, the interior finish spiffs up with better-quality Modena leather stitched around the steering wheel rim, and Senza leather on the wheel center.    Next year, wireless Android Auto and Apple CarPlay will come standard, a promotion over the current wired systems. Getting around the infotainment screens will be easier thanks to a rotary dial that can slide laterally to choose menu items. The digital radio moves up to SiriusXM 360L, providing 4G streaming functionality. For the younger drivers in the family, the Teen Driver System will include Buckle to Drive. On the current CT5-V, the Navigation and Bose Premium Audio Package adds the Cadillac user experience with navigation, a 15-speaker Bose audio system, and an eight-inch configurable Driver Information Center display between the dash cluster gauges. For 2021, the eight-inch display is discontinued, so the package gains wireless phone charging. A new Technology Package replaces the current eight-inch DIC with a 12-inch configurable digital gauge cluster that sprouts a head-up display taken from the Driver Awareness Plus Package. The Technology Package will be included in the Platinum Package that right now costs $6,290, and that automatically adds the $4,190 Premium Package and $1,950 Driver Assist and Advanced Security Package. Based on current prices, the order guide indicates the Platinum Package will cost at least $12,430. Because of such bundling, the same package on the 2020 CT5-V 'roids up the MSRP by $13,730. Without ordering the Platinum Package, both the Navigation and Technology Packages will require the Premium Package.
