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."

Chevy Malibu will become 45-mpg strong hybrid with next update

Come next year there'll be no more mild hybrid pretensions for the Chevrolet Malibu - the next-generation sedan will borrow technology from the 2016 Volt and get a proper hybrid powertrain. A 1.8-liter four-cylinder engine gets help from a two-motor drive unit adapted from the Volt for 182 system horsepower, the motor drive powered by an 80-cell, 1.5-kWh lithium-ion battery. Chevrolet says that when combined with features like grille shutters and a lower ride height, it expects the Malibu Hybrid will post a combined fuel economy rating of more than 45 miles per gallon, which would best the hybrid trims of the Ford Fusion, Toyota Camry and Hyundai Sonata. Electric power alone can power the car up to 55 miles per hour, and The Bowtie's first use of exhaust gas heat recovery will help maintain high hybrid performance in cold weather and be used to heat the engine and cabin. The Malibu Hybrid should go on sale in the Spring of next year, for now there's a press release below. Chevrolet Malibu Hybrid Derives Technology from Volt GM estimates combined fuel economy ratings to exceed 45 mpg DETROIT, 2015-03-25 – Chevrolet's recent production announcement of its all-electric vehicle based on the Bolt EV concept, as well as the introduction of the 2016 Chevrolet Volt, will be joined by a strong hybrid version of the next-generation Malibu. Using technology from the 2016 Chevrolet Volt propulsion system, Malibu Hybrid will offer an estimated combined fuel economy rating exceeding 45 mpg, higher than the combined mileage ratings of the Ford Fusion, Toyota Camry and Hyundai Sonata hybrid variants. "The 2016 Malibu Hybrid will offer impressive fuel economy, exceptional driving characteristics and gorgeous styling," said Jesse Ortega, Chevrolet Malibu chief engineer. "Besides leveraging innovation from the Chevrolet Volt, the Malibu Hybrid also has unique features that help improve aerodynamics, like upper and lower grille air shutters to improve airflow and a reduced ride height, all of which help reduce fuel consumption," Ortega said. An all-new direct-injection 1.8L 4-cylinder engine mated to a two-motor drive unit slightly modified from the 2016 Chevrolet Volt drive unit powers the Malibu Hybrid. The drive unit provides additional power to assist the engine during acceleration, for 182 horsepower (136 kW) of total system power.

Dale Earnhardt, Jr. puts his Callaway Corvette and '55 Chevy on eBay

Dale Earnhardt, Jr. has put a couple of his personal cars up for sale on eBay. The first is a 1955 Chevy Bel Air that Junior had reworked by Funkmaster Flex, a bit of a diversion from Flex's more common Ford efforts. Junior's ride has a replacement chassis from Jim Meyer Racing, a 434 small-block tuned by Sharioff Racing to 500 horsepower, and truly thin rubber on what appear to be aluminum billet rims with Junior's former number 8 on the center caps. The interior is all custom and painted to match the outside, and those seats have been completely reupholstered. The second car is a 1999 Callaway C12, the 18th of 19 C12s built that year and featured in a 2002 issue of AutoWeek. It joined Earnhardt's private collection in 2004. Built on the base of a C5 Chevrolet Corvette and using a lot of technical know-how from Callaway's European racing program, the BMW #287 Blue Pearl C12 had its V8 bored out to 6.2 liters and graced with Callaway's Supernatural upgrade; it also has a Callaway coil-over suspension with adjustable dampers. There's new bodywork all around, and when new it cost about $200,000. At the time of writing bidding on the Bel Air was up to $80,100, the C12 was at $63,100. The auction ends Monday morning, and the winning bidders have the option of having their prizes autographed and retrieving the keys from Dale Jr himself if they're willing to go to Moorseville, NC.
