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."

General Motors and EVs: No stranger to firsts, but where's the leadership?

2015 is already shaping up to be the year of "affordable, 200-mile EV" concepts. Nissan and Tesla have each been talking about them for some time, the latter promising to unveil its Model 3 at the North American International Auto Show in January before balking when the time came. Instead, Chevrolet beat them all by unveiling the Bolt concept at the same event, followed shortly thereafter with suggestions of a 2016 launch – potentially offering the first nationwide EV with anything close to that range. It was the ballsiest EV-related move General Motors has made in a quarter century. But will it remain so? Exactly 25 years before the Bolt rolled up onto the turntable, then-Chairman Roger Smith unveiled GM's last ground-up EV concept, the even-more-unfortunately-named Impact, at the Los Angeles Auto Show in January 1990. A few months later, he surprised most of his colleagues by announcing its intended production in honor of Earth Day. It was the first modern foray into electric vehicles for the US by any automaker, one that was rewarded by the State of California with what is now known as the Zero Emissions Vehicle mandate. The program not only forced other automakers into competing with Roger's pet project, but inspired all of them to fight it like small children against bedtime. Some years later, the drivers themselves weighed in, with a biting documentary about that obstinance and the leadership it cost both GM and the country. Within months, GM was first back into the fray of plug-in vehicles. Many criticized the company for starting with a PHEV rather than jump straight back into EVs. The choice wasn't totally out of the blue – even EV1 was meant to be followed by a PHEV. And especially on the heels of Who Killed the Electric Car?, some skittishness was understandable: even a successful EV would invite a "we told you so" public reaction, underscoring their mistake in ending the EV1 program. If a new EV didn't do well, they'd be convicted in the public eye as serial killers. All while seeking a federal bailout. For all the flak, the resulting Chevy Volt was and is a better car than GM has ever gotten credit for. But the company seemed to grow weary of having to overcome its varied past, and while the current owners remain happy, much of the stakeholder and community engagement that so effectively built early goodwill and sales growth faded not long after launch. Marketing has been spotty in both consistency and effectiveness.

Chevy Silverado HD gets the Custom Sport treatment

Everyone remember the Silverado 1500 Custom Sport Chevrolet showed at the 2015 Detroit Auto Show? Good. Now, the company has applied the same styling treatment to its heavy-duty pickups, introducing the 2500 and 3500 Custom Sports. The two trucks appeared today at the 2015 Denver Auto Show. A monochromatic look is the order of the day, with the heavy-duty Silverados getting body colored bumpers both fore and aft as well as a body color grille. Chrome accents sit in said grille, while the shiny finish can also be found on the door handles and mirrors. Buyers of the 2500 Custom Sport will get five-spoke, 20-inch, polished wheels, while the brawnier 3500 gets 18-inch polished hoops as standard (dualies are downgraded to 17-inchers).
