Chevrolet Malibu could last until 2024 before joining the dodo

Automotive News pieced together all available intel on the Chevrolet and GMC lineups, trying to ascertain how much life each model might have left. Concerning the Chevrolet Malibu, the answer is not too much, and the historic nameplate's final years don't look like the glory kind. After a major overhaul in 2016 boosted sales for the ninth-generation sedan to 227,881 units, the 2018 sales fell to 144,542, and this year's are down almost 15% through the end of June. The Malibu is one of two Chevrolet sedans still breathing - the other being the Impala for now - but only for about five more years. AN says there'll likely be a refresh in 2022, followed by a visit from the Reaper in 2024. After that, it could be "indirectly replaced" by an electric vehicle, one of the 23 EVs that GM is working on for 2023.     The Impala will meet the ax earlier despite a recent stay of execution. Production is still set to close in January 2020. In the entire GM stable, Cadillac might soon be the only marque with sedans. The Buick LaCrosse has a date with death, and Groupe PSA won't supply Opels-as-Regals forever.  The Sonic hatchback should say goodbye at the end of 2020, a year before the seemingly eternal Spark is thought to die. Two years after that, according to one report, the Camaro will go back into cold storage, perhaps forever, and AN says an "expected redesign of the car in 2021 was reportedly canceled." Finally, let's give one final shout-out to the Chevrolet Cruze, a global nameplate, which in the United States alone outsells the Malibu, outsold the Camaro by a factor of three last year, and absolutely trounces the Impala, Sonic, and Spark. Even that couldn't get a stay of execution. In more uplifting news, everything's happening on the crossover and truck side in the next few years. The Chevy Bolt is due for a refresh next year, even though it has "become more important for self-driving ride-hailing fleets that GM Cruise plans to operate than for consumers." In 2021, the Bolt-based crossover should bow, first in China, then here. It's said to look like "a mix of the Bolt and Trax" in spy shots. Still waiting for a green light: a possible subcompact GMC crossover called Granite that might make it to market by 2023. The full-sized SUV triplets Tahoe, Suburban, and Yukon could show their new faces in 2020. The Silverado might get an updated interior in 2020 or 2021, while the Colorado and Canyon mid-sized pickups won't get attention until perhaps 2023.

'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).

2019 GMC Sierra revealed with CarbonPro bed and new diesel engine

It's only March, and it's already been one hell of a year for trucks. January's Detroit Auto Show saw the reveals of the 2019 Ram 1500, 2019 Ford Ranger and the 2019 Chevy Silverado. The Chicago Auto Show brought new versions of the Toyota Tacoma and Toyota Tundra TRD Pro. Today, we finally got our first look at the Silverado's twin, the 2019 GMC Sierra. The truck features new styling, a new diesel engine and — on the Sierra Denali — a carbon fiber bed. As with every new full-size truck, the Sierra is larger than the outgoing model in almost every dimension, though exact dimensions haven't been revealed. For reference, though, the Chevy Silverado's bed is 7-inches wider than before. The new Sierra grille is more upright than before and features new C-shaped lighting. The Denali gets LED headlights, tail lights and fog lights. Both SLT and Denali trims get unique 22-inch wheels. As we saw in spy photos, the Sierra's interior is mostly just a copy of the Silverado's with some chrome accents sprinkled throughout. If you like the current truck interiors, you'll be pleased with the new model. Those hoping for a wholesale change will be left wanting. The big improvements inside include a full-color heads-up display, trailer hitch assist apps and cameras, and the rear-camera mirror found in models like the Chevy Traverse and Cadillac CT6. Safety and convenience features include a surround-view camera, blind-spot monitoring, pedestrian detection and low-speed automatic braking. Like the Silverado, there's been a significant effort to cut weight in the new Sierra. The 2019 model loses as much as 360 pounds compared to the current truck. It uses aluminum for the doors, hood and tailgate. Steel is still used for the fenders, roof and standard cargo box. The Denali, however, gets the real surprise here. Available only on the top-tier trim, the bed box will be constructed of carbon fiber rather than steel, saving 62 pounds. Carbon fiber only replaces the steel inner panels and floor. GMC says the carbon fiber will also help scratch and corrosion resistance. SLT and Denali models also get a new MultiPro tailgate. This is unique to the Sierra and separate from the Silverado's power assist unit. A new feature that helps one get into and out of the bed using an assist handle. The tailgate step has a maximum weight capacity of 375 pounds. There multiple positions that allow customers to extend the bed, or drop the center vertically to gain easier access to the back.
