2015 Chevrolet Silverado 1500 Custom Sport Quick Spin

Coincidentally, the week we had the 2015 Chevrolet Silverado 1500 Custom Sport a friend asked, "What would you buy if you could only have one vehicle for everything?" After a week's driving and trailer hauling, very close to first choice would be an American pickup. They're all so good now, you can't lose. And as we found in the Chevy you can go anywhere and haul anything, and you pay no penalty for capability until you try to find an open space on the street to park. Nicely equipped versions like the Custom Sport aren't cheap, but if you need a truck and you like the look of this one, it is really good. Driving Notes The cabin is big and inviting, and everything in it is big and inviting. The materials are nice enough to look and feel swanky but not so lavish that you're afraid to get them dirty. The seats are sized for adult male bears but they don't swallow you up. The sunroof is big enough to be an observatory. It's also quiet. The only time it gets mildly unruly is when you call for power and the engine has to downshift a few gears, otherwise you don't hear the exhaust unless you roll down the window. It looks like it was designed with a T-square. I quite like it, the body-colored bumpers toning things down, the 20-inch wheels doing a much better job of filling those ample arches than the standard 17-inchers. The truck is built for people who take their work and all their gadgets with them. The front console has three USB ports, two 12-volt cigarette lighter ports, and a three-prong 110-volt outlet. The giant cubby at the base of the console has an insert to hold a clipboard or a small tablet. The abyss under the center armrest has one more 12V cigarette lighter, two more USB ports, an SD card reader, and another specialized holder for something the size of a small tablet. There's a WiFi hotspot so the streaming never has to stop. The Chevrolet navigation was trouble-free as usual, and you can input destinations on a QWERTY touchscreen keyboard. Every nav system should be so solid. The Silverado has some of the best feature implementations we've encountered in any vehicle. The lane departure warning and park assist systems don't vibrate the steering wheel, they vibrate the seat. The left, right, and middle of the seat bottom will pulse as necessary, an intuitive, peripheral way to deliver a message that doesn't interrupt your primary focus. The rear-view camera is no longer offset, it's centered.

GM won't pay owners of recalled cars for lost value

Kenneth Feinberg, the man in charge of the General Motors compensation fund dealing with the its widespread ignition switch woes, has issued an informal, two-letter response to the plaintiffs in more than 70 lawsuits seeking redress for lost resale value of their Cobalts: "No." The cases were recently combined into one, but Feinberg told The Detroit News that the fund will deal "only with death and physical injury claims," and that "perceived diminished value" will get no consideration.
ALG, the firm specializing in establishing residual values, determined that Cobalt owners had lost $300 compared to the segment competition and doesn't envision any long-term effects from the recall situation. Feinberg's statement comes in advance of public details on how the compensation fund will work and adheres to GM's long-held position on the matter. The company has already asked a judge to throw out such suits using the pre-bankruptcy defense, even as it stopped using that defense in cases of injury and death.
With plenty of potential gain from the GM suit, however, don't expect the plaintiffs to give up yet. When Toyota was sued for the same reason during the unintended acceleration debacle, it eventually settled the case for between $1 billion and $1.4 billion just to get it over with. Since the 85 law firms involved in the Toyota litigation took home more than $250 million of that total, we shouldn't expect the attorneys to give up on a GM payout, either.

'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).
