Weekly Recap: New bosses try to jump-start Cadillac and Lincoln

Both of America's domestic luxury brands seem to be stuck in neutral.
It's ironic that Cadillac and Lincoln got new bosses within days of each other this month. It's also a commentary on the fact both of America's domestic luxury brands seem to be stuck in neutral.

Sunday Drive: Classic American nameplates and one exciting new German

Our look back at last week's biggest automotive stories focuses first on the Jeep Wagoneer, an unequivocal American classic. Not only did the Wagoneer play a pivotal role in kicking off America's current love affair with the sport utility vehicle, it legitimized the Jeep brand in the mind of consumers looking not just for something to ably take them off the beaten path, but to do so in comfort, with the entire family along for the ride. So it comes as little surprise that Jeep decided to take one vintage Wagoneer, modernize it with a 5.7-liter Hemi V8 engine, and put the thing on display as part of its annual Moab Easter Jeep Safari. We're in love. Our next two stories focus on Cadillac. First up is news that the striking Escala Concept is headed for production in 2021 to serve as the brand's flagship luxury sedan. The second story involves Caddy's current top rung, the CT6, which gets a new twin-turbo V8 engine as part of its V-Sport package. And finally, we round out this look at last week's headlines with the 2019 Mercedes-Benz C-Class Coupe and Cabriolet. We're mighty keen to try out Benz's new AMG-fettered turbocharged inline-six engine, and the C Coupe looks like a fine point of entry. As always stay tuned to Autoblog this week for all the latest automotive news. Jeep delivers basketful of concepts for the Moab Easter Jeep Safari Cadillac's striking Escala concept is reportedly headed for production Cadillac CT6 V-Sport wants to take prisoners with 550-hp 4.2L TT V8 2019 Mercedes-Benz C-Class Coupe and Cabriolet revealed ahead of New York

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."
