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.

Everything new at the 2019 New York International Auto Show

Transcript: Welcome to the 2019 New York Auto Show. It's the last auto show, and so far it's my favorite of the year. We have a new buggy, compact pickup and trail ready SUV from Volkswagen. Ford brought the new Escape and a new Mustang performance variant, and we have a brand new Toyota Highlander and Subaru Outback. Let's go take a look around. We're here at the New York Auto Show with the Subaru stand. Normally the Subaru stand is just some white carpet and some show lighting. This year it's like we're in a national park. It's ... Frankly, I'm from Oregon. You're from Colorado. Yeah. It's making us feel at home. And in that way what better place and what better people to introduce this Subaru Outback which is pretty much the official car of Colorado and Oregon. Yeah. You actually have to buy a Subaru before they let you move to Colorado. Now instead of climbing up there and taking a look because we've been told we can't do that we're gonna go over there and check out another one. So the exterior, not that different. No. Looks exactly like an Outback. There's actually oddly a little more black plastic trim on the outside. A little too much for me. Right. It's interesting because it kind of slowly went away from that from the beginning because in the beginning the black plastic trim kind of made it an Outback, and now they're kind of bringing it back. I guess they needed to make it more macho. Right. Right. Now we're inside. Inside it looks pretty different. Swank. It's kind of swank for an Outback which has been pretty plain. Now this is the newly available vertically gigantic touch screen here. 11.6 inches. That is massive. This is how big it is when it's turned on ... just for the viewers. Now this is the onyx trim. So with that you get the black mirrors, the black wheels. This upholstery is special to the onyx, so it's gray and black and you also have this green stitching. Yeah, I like this accent stitching. It's kind of neat. Oh there's also a little tray there. Well this is a deep bin here. You can probably fit a phone. There we go. Almost. Yeah there are two USB ports. There's an additional two in the backseat. So this thing here you pop in the cup holder and it gives you a little more space or less space. These are really big, so if you have one of those Nalgene bottles I'm guessing it's going to fit in there. One of my complaints about my Subaru that I own now which is a naturally aspirated Crosstrek is that up in the mountains. It's slow?

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.
