Next-gen GMC Sierra spied with diesel power

The next generation of GM trucks is arriving soon, and we're expecting a huge leap forward over the current lineup. The Chevy Silverado and the GMC SIerra sell extremely well, but haven't done much to move the segment forward in a long time. The Ford F-150 has an all-aluminum body and turbocharged V6 power. The Ram 1500 gained a diesel and coil spring suspension. These spy shots show that diesel may be in the cards for GM. Some quick shots and copious use of flash show what is most likely a tank for diesel exhaust fluid and a diesel particulate filter, both necessary equipment for any modern diesel. It's unclear what form factor that engine will come in, though GM has a number of engines to choose from, including the 2.8-liter inline four that's found in the Colorado and Canyon, though that may be a little light duty for the Silverado and Sierra. Other rumors surrounding the trucks suggest a move to an aluminum cab while retaining a steel bed. That seems like a reasonable move for GM, even if the company was attempting to shame Ford for its move to aluminum a few years ago. Look for more news as early as the Detroit Auto Show in January.

'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).

Volvo and GM team with Amazon for in-car deliveries

Volvo and GM are the first automakers to pair their vehicles with a new service from Amazon that lets owners have their packages delivered inside their cars, without them having to be there. The service will initially be rolled out in 37 U.S. cities at no extra charge to Amazon Prime members with a Volvo On Call or OnStar account, and it works with same-day, two-day and standard shipping. It's intended as an alternative for people who don't want to risk having their package stolen from their front porch or receive deliveries at their workplace, and both automakers say it's an example of how they're embracing innovation as a way to make their customers' lives easier. Volvo released a video (above) showing how the service works. Users download the Amazon Key App (or " Ama-zin," as the narrator pronounces it) and link their Amazon Prime account with their Volvo On Call account — or OnStar, in the case of GM-branded vehicles. Once they register their delivery location in a publicly accessible location, users can select the "In-Car" option at checkout. They get a notification when the delivery is en route and once it's completed and the car is relocked. Volvo has been offering in-car delivery in certain European countries since 2015 through its Volvo On Call platform, which enables services like the ability to send calendar-based navigation destinations directly to the vehicle, find nearby gas stations and help locate the vehicle when you forget where you parked it. Volvo says the platform is now available in roughly 50 countries and covers more than 90 percent of its global sales. The service is compatible with 2015 or newer Volvo, Buick, Cadillac, Chevrolet and GMC vehicles. Volvo says it's available to the majority of Volvo owners, while GM says more than 7 million vehicle owners can qualify. The service is expected to roll out to more cities later.
