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."

Cadillac upgrades ATS sedan to match new coupe

The big news when it comes to the Cadillac ATS for 2015 is surely the addition of the new coupe model, but that doesn't mean that Cadillac has forgotten about the sedan as well. In fact GM's luxury brand has rolled out a few choice enhancements for the four-door to bring it more in line with the new coupe.
Among those changes that we spotted a couple of weeks ago is a new front fascia that incorporates the brand's new wreath-less emblem, and a sleeker front bumper. The interior has been upgraded as well with new trim options as well as some new tech including Siri Eyes Free functionality, dictated text messaging and optional inductive smartphone charging.
Though the ATS Coupe does away with the base engine, sedan buyers can still opt for the 2.0-liter four with 202 horsepower and 191 pound-feet of torque. The 3.6-liter V6 carries over unchanged at 321 hp and 275 lb-ft, but the 2.0-liter turbo four gets the upgraded torque rating of 295 lb-ft (the highest in the range) to go with its 272 hp. Some new color choices are also among the upgrades you can read more about in the press release below.

GM recalling 117,000 sedans, crossovers, SUVs, pickups and vans

General Motors has issued a stop-sale to dealers and has notified the National Highway Transportation Safety Administration of its intention to recall 117,000 vehicles in the United States, Canada and Mexico. Of those vehicles, only 4,500 are at dealerships.
The affected vehicles include the Cadillac CTS and Chevrolet Impala sedans, fullsize SUVs (Cadillac Escalade, Chevy Tahoe and Suburban and GMC Yukon and Yukon XL), Lambda-platform crossovers (Chevy Traverse, Buick Enclave and GMC Acadia), heavy-duty pickups (Chevy Silverado HD and GMC Sierra HD) and fullsize vans (Chevy Express and GMC Savana). The sedans and body-on-frame SUVs include model years 2013 and 2014, while the CUVs, heavy-duty pickups and vans are limited to MY2014.
GM confirmed the recall to Autoblog via an emailed statement (which we've included below). According to the statement, the issue at hand in what is the company's 69th recall of 2014 covers the chassis-control module. Automotive News is reporting that a problem in the chassis-control system could cause a short in the module, which could cause the engine to stall or fail to start. The fault could also affect the trailer-brake control, provided it's equipped.
