GM to restore legendary Corvette damaged in sinkhole accident

Car lover's hearts' sank when they saw images of bent and destroyed classic Corvettes at the bottom of a sinkhole last February after the floor of the National Corvette Museum gave way. General Motors announced Wednesday it would restore the one millionth Corvette ever produced to its former glory. The 1992 convertible was heavily damaged when a 40-foot deep sinkhole opened beneath a bevy of rare cars at the National Corvette Museum in Bowling Green, Kentucky. Since then, GM has been slowly restoring the classic cars, though five of the eight that caught in the sinkhole were determined to be too damaged to repair. This November, the 2009 Corvette ZR1 Blue Devil was the first car to be returned in mint condition to the Museum, according to Autoblog. It suffered significant damage but was still drivable after being pulled out of the debris. The one millionth Corvette is still in bad shape. The automaker is estimating six months worth of work to restore the car, which sustained paint scratches, rear-suspension damage and a mangled front fender.

GM to invest $632 million in Indiana plant for future pickup truck production

General Motors plans to invest $632 million in its Fort Wayne, Indiana, assembly facility to prepare the plant for future internal combustion engine full-size light duty trucks, it said on Monday. The investment will be used to support new conveyors, tooling and equipment for the plant that manufactures GM's Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. GM has detailed more than $2.3 billion in planned investment in a series of announcements since last week as it works to retool existing North American auto plants and introduce more efficient next-generation internal-combustion full-size trucks and SUVs. Another investment announcement is planned later this week. The largest U.S. automaker is continuing to make big investments in gas-powered vehicles even as it vows to stop building them in 2035. Last week, GM said it was investing more than $500 million in its Arlington, Texas, assembly plant to prepare it for production of internal combustion engine full-size SUVs. GM faces increasingly stringent emissions requirements from California and the Environmental Protection Agency (EPA). Last week, GM also said it plans to invest more than $1 billion to re-tool two manufacturing sites in Flint, Michigan, to prepare for a new generation of its heavy-duty trucks. The Texas announcement highlights the company's commitment to continue "providing customers with a strong portfolio of (internal combustion) vehicles for years to come," GM said last week. On Tuesday, GM said it would invest C$280 million ($210 million) in its Canadian Oshawa Assembly to produce the next-generation internal combustion engine full-size trucks. GM paid $128.2 million in fines for failing to meet Corporate Average Fuel Economy (CAFE) program requirements for 2016 and 2017, records released recently show. The EPA in April proposed requiring a 56% reduction in projected fleet average emissions over 2026 requirements.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
