GM reintroduces Tripower name in the worst way possible

The story of General Motors' use of the Tripower moniker begins way back in 1957, when Semon E. "Bunkie" Knudsen, then General Manager of GM's Pontiac division, directed his engineers to inject more performance into his brand's line of V8-powered automobiles. Fuel injection was an option, but hot rodders flocked instead to Tri-Power (marketed way back when with a hyphen), which grafted a trio of two-barrel Rochester carburetors onto a single intake manifold. A legend was born. And that legend was born of performance. At idle and when full power wasn't required, Pontiac's Tri-Power system used just the middle carburetor, which helped make the setup easier to tune. Depending on the year and model, either a vacuum system or a mechanical linkage opened up the two outer carbs, thereby switching from two barrels to six, and allowing the engine to take in more fuel and air. And it was an easy marketing win – six barrels is better than four barrels, right? Because performance! So, when news filtered in that GM has resurrected the Tripower name, those of us who grew up attending classic car shows and wrenching on old Pontiacs did a double-take. And then we all collectively sighed. Turns out that today's Tripower refers to a trio of fuel-saving measures that include cylinder deactivation, active thermal management, and intake valve lift control, according to Automotive News. And, at least for now, it applies to GM's line of fullsize trucks powered by a 2.7-liter turbocharged four-cylinder engine. We're all for saving fuel whenever possible. And we have zero say in how any automaker chooses to market its products and technologies. But, we'll offer our two cents anyway: Relaunching a storied name from the past is fine. Relaunching a storied name from the past while completely overlooking the reasons the name got famous in the first place is only going to irritate the people who remember the name in the first place. Couldn't they just call this new technology package something else?

NHTSA investigating nearly 750,000 GM models over non-deploying airbags

Nearly 750,000 vehicles built by Chevrolet, GMC, and Cadillac are the subject of a National Highway Traffic Safety Administration (NHTSA) investigation due to non-deploying driver-side airbags. While the investigation is ongoing, the agency believes the issue is likely due to rust particles that form on the inflator's connection terminal interface. The list of nameplates included in the investigation includes Chevrolet's Silverado, Tahoe, and Suburban, GMC's Sierra, Yukon, and Yukon XL, plus Cadillac's Escalade, Escalade ESV, CT4, CT5, and XT4. All of the potentially affected vehicles are 2020 or 2021 models, according to a bulletin published on the NHTSA's website. Investigators launched the probe in April 2021 after 15 consumers reported airbag-related issues, including nine who said an airbag malfunction light appeared in the instrument cluster. More alarmingly, the NHTSA is aware of six accidents that caused significant damage to the car's front end yet didn't trigger the driver's airbag. It adds that there are no fatalities linked to the issue, but there are six crashes and eight injuries reportedly blamed on it. No evidence suggests this problem is related to the millions of potentially deadly Takata inflators recalled over the past few years. General Motors is aware of the defect. It sent a technical service bulletin (TSB) to its dealers in March 2021 to address the aforementioned warning light. The note explains the issue is due to "rust particles in the connection terminal interface of the driver's airbag inflator." The company hasn't issued a safety recall yet, however. Whether it will partially depends on the NHTSA's findings. It's currently looking into the scope and the severity of the problem, and it wants to understand its implications on driver safety. Investigators will decide whether General Motors needs to recall the 749,312 cars that are part of the probe when they close their investigation. General Motors has already spent a significant amount of money replacing defective airbag-related parts in its cars. In November 2020, it was ordered by the American government to recall nearly 6 million pickup trucks and SUVs equipped with potentially dangerous Takata airbag inflators. It repeatedly argued that testing proved the inflators were safe, and it petitioned the agency four times starting in 2016 to avoid a recall, which cost an estimated $1.2 billion (about a third of its net income in 2020).
