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 ELR, Nissan Resonance and Ford Atlas win Eyes on Design awards

This year's annual Eyes on Design awards were presented at the end of press days for the Detroit Auto Show on Tuesday. Given out for the best production and concept car designs that debuted at the show, and voted on by an esteemed panel of actual car designers, this year's award for best production vehicle design went to the 2014 Cadillac ELR. The 2014 Chevrolet Corvette, which was the show favorite among Autoblog editors, apparently did not impress the Eyes on Design judges enough with its all-new vent-festooned design.
The award for best concept design was actually split as a tie among the Nissan Resonance and Ford Atlas concepts. Last year's winners were the 2013 Ford Fusion and the Lexus LF-LC concept.
The Eyes on Design organization also presented a new honor this year called the Catalyst Award to Bob Lutz, former Vice Chairman of General Motors. Lutz is reported to have given a defense of design in his acceptance speech, arguing that advancements in quality across the industry as a whole have made good design a key differentiator for buyers.
