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.

Jay Leno welcomes a 2016 Cadillac CTS-V into the garage

After checking out a multitude of classic cars and customs over the past few weeks, Jay Leno switches things up with a modern performance machine in the latest video from the garage – a 2016 Cadillac CTS-V. Leno is curious about Caddy's attempt to challenge the BMW M5 and Mercedes-Benz E63 AMG S, and he takes a long, technical look at the sedan with chief engineer David Leone. Not content to just peek under the hood, Leno puts the CTS-V up on the rack to see what it packs underneath the svelte body. Once he gets the lowdown on the Caddy's engineering, it's time for a drive. Leno also flexes his interviewing skills while behind the wheel and gets even more info about the CTS-V's capabilities from Leone. He seems fairly impressed, but Leno's most entertaining question about the 640-horsepower sedan is whether it can do a burnout. He provides a definitive answer to that at the end of the clip.

Cadillac moving to NY as separate business unit

Cadillac is under new leadership, and the automaker is committed to turning itself (back) into a global luxury powerhouse. It's got a strong product offensive (of products currently in showrooms, and much more on the way), and now it will have a new location to call home.
Following earlier speculation, GM has confirmed that it is moving Cadillac's base of operations from Detroit to New York. Lest you think it might rent offices in the Chrysler Building (which is, after all, one of the tallest in the city), the new Cadillac global headquarters will be located in the Soho area with a "multipurpose brand and event space in conjunction with modern loft offices." The company is still evaluating which staff will move along with it to Manhattan, and which will remain in Michigan where technical operations will still be based.
The move from Detroit to New York is the first major change being instituted by new Cadillac chief Johan de Nysschen, who previously undertook a similar shift in moving Infiniti away from Nissan headquarters to its own facility in Hong Kong. Ford had attempted a similar move in relocating its luxury portfolio under the Premier Automotive Group (which then included Lincoln, Mercury, Land Rover, Jaguar, Aston Martin and Volvo) from Dearborn to Irvine, CA, but ended up moving Lincoln (the last one still under the Ford umbrella) back to Michigan. Other luxury automakers like Audi (Volkswagen) and Maserati (Fiat) are headquartered away from their parent companies as well, but have a longer history of independent operation.
