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."

2016 Chevy Malibu gets premium looks, hybrid model

The Chevrolet Malibu was once an automotive icon, but its modern reputation is one for underachievement. A new 2016 model seeks to restore the storied nameplate with improved styling, more interior room and a new hybrid version. It debuts Wednesday at the New York Auto Show. Put simply, "the goal was to put Chevrolet back in the midsize car segment," said John Cafaro, the brand's executive director of car design. In a crowded arena with 2.2 million sales up for grabs annually, Chevy has not been a player. Last year, the brand sold 188,519 Malibus, a six-percent decline from 2013, and fewer than half the number of Toyota Camrys and Honda Accords sold. Despite awards from J.D. Power and Associates and the Insurance Institute for Highway Safety, Chevy knew the Malibu needed a big change. New Skin, Lighter Bones The redesign has been in the works for at least three years. Although the Malibu is still based on GM's Epsilon 2 platform, the underpinnings are more derivative of the Impala than the outgoing model. The body structure makes greater use of high-strength steel, which helps reduce weight by 300 pounds. Size is more Impala-like as well, with 2.3 inches more overall length and a 3.6-inch wheelbase stretch contributing to greater interior space. A new skin covers the Malibu's lighter bones, and design language from the Impala gives its sibling sedan a fresher, more upscale appearance. To execute this premium appearance, Chevy turned to 25-year-old designer Jaymer Starbody, a four-year General Motors veteran and graduate from Detroit's College for Creative Studies. He described the new Malibu as having a "wheel-oriented" design, and the car looks poised to pounce from certain angles. Though the 2016 Malibu is the same width as before, designers stretched the creases and angles in the sheetmetal to create a flatter, sleeker appearance. The hood and cowl are lower, and the Malibu's face sparkles with LED running lamps on the top trim levels. Inside, the roomier cabin has a new center stack, satin chrome accents on the interior panel and a console storage area designed for mobile devices. Chevy MyLink with a seven-inch color touchscreen is standard on lower trims, and the top model upgrades to an eight-inch screen. Perforated leather seats and ambient lighting are also available options. The cabin was designed to look high-tech, but still remain easy to use, according to Chevy interior design director Crystal Windham.

GM to invest $150 million in Flint to boost heavy-duty pickup production

FLINT, Mich. — General Motors President Mark Reuss said on Wednesday that the automaker is investing about $150 million at its Flint Assembly plant in Michigan to boost production of heavy duty trucks by another 40,000 vehicles a year. Reuss announced the investment at the Flint truck assembly plant wearing a United Auto Workers pin. The Detroit automaker had announced back in February it was adding 1,000 jobs in Flint to build a new generation of heavy-duty pickup trucks. GM did not say that the latest investment would add more jobs at the plant, but Reuss said there could be opportunities to add workers as the launch of the automaker's new trucks progresses. GM has been under pressure from President Donald Trump and lawmakers of both parties to add jobs in the United States after it said last November it would idle the Chevy Cruze assembly plant in Lordstown, Ohio, and likewise had no new products for three other U.S. manufacturing plants. The Flint investment will include upgrades to the plant's conveyors and other new tooling, and will be completed in the first half of 2020. GM has invested more than $1.6 billion in the plant since 2013. Last month, GM said it would invest $24 million to increase truck production at its assembly plant in Fort Wayne, Indiana, which makes Chevrolet Silverado and GMC Sierra models. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM's Chevrolet and GMC brands have long trailed Ford's F-series heavy duty trucks in the lucrative segment. The new Chevrolet and GMC heavy duty trucks have been re-engineered to tow heavier trailers, and keep pace in what has become an arms race among the Detroit Three automakers to claim superior torque and towing capability.
