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.

Cars with the worst resale value in 2022

Car values are all over the map right now. Used vehicles that were worth a small fortune earlier this year are now coming back to Earth, but the new vehicle supply remains tight. Prices are still elevated overall, but some models have seen more severe price drops. Depreciation strikes almost every model, supply constraint or not, though a few vehicles are leading the way. New research from analytics iSeeCars found that a handful of cars depreciated more than 50 percent over five years, with the BMW 7 Series dropping 56.9 percent and an average price cut of $61,923 over that time. The vehicles with the highest depreciation — or worst resale value — over five years: BMW 7 Series: -56.9% Maserati Ghibli: -56.3% Jaguar XF: -54% Infiniti QX80: -52.6% Cadillac Escalade ESV: 52.3% Mercedes-Benz S-Class: 51.9% Lincoln Navigator: -51.9% Audi A6: -51.5% Volvo S90: -51.4% Ford Expedition: -50.7% iSeeCarsÂ’ research showed that midsize trucks, sports cars, and fuel-efficient vehicles were slowest to depreciate over five years, while itÂ’s clear that luxury brands tend to lose value much faster. As iSeeCarsÂ’ Executive Analyst Karl Brauer explained, used buyers donÂ’t value high-end vehiclesÂ’ features as much as the first owners, so resale values tend to be softer. The tech and options that made the cars so expensive and appealing new donÂ’t add the same value on the used market.

The Nissan Leaf depreciated most among EVs, dropping by 49.1 percent. The average EV depreciation is 44.2 percent, with the Tesla Model S and Model X sliding in right under the bar at 43.7 and 38.8 percent, respectively. As iSeeCars notes, itÂ’s important to be vigilant when car shopping and not let your emotions win over reason. Shiny new luxury cars look great in the showroom, but you could end up taking a bath when you try selling them a few years later on.

de Nysschen pushes to separate Cadillac, GM

Cadillac President Johan de Nysschen continues his push to separate his brand from General Motors. After controversially picking up shop and moving to New York's trendy SoHo neighborhood, de Nysschen has now gone on record as saying that within two years, the brand will enjoy "a far higher degree of autonomy and self sufficiency." That autonomy will include the brand reporting its own financial results, independent of GM. But what would such a move do for Cadillac? Well, as de Nysschen explained it to Automotive News, "Cadillac at this state makes a very sizeable contribution to the overall profit at General Motors." If that's truly the case, separating financial announcements serves to emphasize the prosperous character de Nysschen seems so keen on attaching to his brand. But that's only one phase of Cadillac's push to distance itself from GM. De Nysschen is eager to revamp the company's dealership model so that it stands out from other GM brands, calling it a "very profound focus." Those moves, according to AN, including a change to the current dealer incentive model with a particular emphasis on building the brand rather than nailing sales figures. "If you aren't strengthening the brand perception, you should have less reward," de Nysschen told AN. While his goals seem clear, de Nysschen's statements have left us wondering whether they're also somewhat counterintuitive. Emphasizing Caddy's prosperity to potential consumers while incentivizing dealers to move less metal seems more like a tactical move rather than a strategic one. And there's no telling how the new dealership model will impact de Nysschen's goal to hit 500,000 global sales by 2020. Related Video:
