GM’s Charlie Wilson was right: Stronger regulations can help U.S. automakers

Charlie Wilson had been the president and CEO of General Motors before being nominated to become secretary of defense by Dwight Eisenhower. During his Senate confirmation hearings, he controversially said, "For years I thought what was good for our country was good for General Motors, and vice versa." And he was right. While car companies aren't necessarily the most progressive when it comes to things that might have the slightest possibility of political blowback, General Motors should be credited for doing something absolutely forthright in this regard with its announcement that it wants the federal U.S. government not to squash the California Air Resources Board's emissions requirements but to actually create a 50-state "National Zero Emissions Vehicle" program that, in the words of Mark Reuss, executive vice president and president, Global Product Group and Cadillac, "will drive the scale and infrastructure investments needed to allow the U.S. to lead the way to a zero emission future." Filing comments to the Safer Affordable Fuel-Efficient Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks is one thing. But a graphic the company developed for this announcement — shown above — is something else entirely, something that is absolutely credible, creative and clever. There is a photo of a Chevrolet Bolt EV driving along a highway, which seems to be in Marin County (based on the blurred San Francisco skyline in the background). Text on the photo states: "It's Time for American Leadership in Zero Emissions Vehicles." It seems to say, in effect, "If we want to make America great again, then we're going to do it by leading in technology, not by retreating behind weakened regulations." General Motors understands that the auto market is globally competitive, and if U.S.-based companies are going to be in the game, then they'd better be able to out-innovate the companies based elsewhere, where emissions and economy standards are not being weakened.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Millionth Corvette now being restored after sinkhole damage

Among the original American sports cars that were damaged by the sinkhole at the National Corvette Museum over a year ago was a 1992 convertible that was the millionth Vette made. And now that milestone vehicle is starting its restoration process. The landmark Corvette's rehabilitation is being carried out by the GM Design Center in Warren, MI, by a team of skilled craftsmen and technicians. The crew is more accustomed to building prototypes and concepts, but will face a new challenge in bringing this millionth Corvette back to its original condition. The white-over-red convertible was one of eight Corvettes that were swallowed up by the sinkhole at the museum in Bowling Green early in the morning on February 12, 2014. Five will be preserved in their compromised condition as part of a display demonstrating the effects of the sinkhole, while the remaining three were earmarked for restoration. The Design Center team has already completely the restoration of the 2009 Corvette ZR1 "Blue Devil" prototype, while the remaining 1962 Corvette will be restored by the museum.

The restoration crew is part of GM's Mechanical Assembly group at the Design Center, which typically spends its time building prototype and concept vehicles. The white 1992 Corvette is a challenge because rather than build an all-new vehicle from the ground up, the workers are trying to preserve the original appearance of a production vehicle. It is the second of three sinkhole-damaged Corvettes that Chevrolet has pledged to restore. The first, a 2009 Corvette ZR1 prototype known as the Blue Devil, was only lightly damaged and was returned to its original condition last fall. The National Corvette Museum will oversee the restoration of the third car, a 1962 Corvette. Five other Corvettes swallowed by the sinkhole will remain in their as-recovered state to preserve the historical significance of the cars. They will become part of a future sinkhole-themed display at the museum. Sinkhole summary On Wednesday, Feb.
