GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

GM's Super Bowl ad puts Will Ferrell and EVs in Netflix shows

GM is kicking off the automotive Super Bowl commercial season with EVs and Will Ferrell. The ad highlights GM's new relationship with Netflix in which the automaker's many upcoming electric cars and trucks will appear. More specifically, the ad has Will Ferrell appearing in settings from major Netflix TV movies and shows such as "Army of the Dead" and "Squid Game," talking about how there's no reason not to have EVs there. And then he also appears with EVs in shows where they don't make sense, such as "Bridgerton" and "Stranger Things," but only to reassure people that Netflix won't be shoving new cars where they don't fit in. The GM lineup on display is pretty varied, with the GMC Sierra EV, Hummer EV, Chevy Blazer EV, and Cadillac Lyriq all making appearances. Most interesting is the Chevy Silverado EV Trail Boss in the "Stranger Things" part. Chevy hasn't said much about it beyond a teaser and saying it'll be a late addition to the line. It looks pretty much like the truck in the teaser with the black plastic front fascia and fender flares. But it gets different wheels, Trail Boss badges on the rear pillars, and a gloss black roof like the RST trim. Related video: 2024 Chevy Silverado EV | 2022 Chicago Auto Show

Dodge vs. Chevy tug-of-war taken to the extreme

They say "idle hands are the devil's playground," but said playgrounds grow to Disney-sized proportions when a pair of jacked-up trucks, two egos, a chain and an empty mall parking lot are involved. Proof of this is the video below, which shows a Cummins-powered Dodge Ram circa 2006 to 2008 chained tail-to-tail with what looks to be a gasoline-powered Chevrolet Silverado from the late 1990s or early 2000s.
We don't necessarily have to tell you who wins this battle, but we'll let you see for yourself the lengths the "winning" driver goes to prove his point. There's plenty of foul language in the video below, so beware that this might be Not Safe For Work, and not that we should have to tell you, but please, do not try this at home.
