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.

"Turbo" Chevrolet Camaro is a 700-HP fantasy car come to life [w/video]

For a concept car built to promote an animated movie about a snail that wants to go racing, this thing ain't half bad. The outsized monster you see before you started life as a Chevrolet Camaro ZL1, and then went through a big-time Hollywood makeover before being positioned on the Chevrolet stand here in Chicago.
This 2013 "Turbo" Camaro Coupe is getting the promotion machine ratcheted up for a new DreamWorks tale by the name of, you guessed it, Turbo. Coming this summer, the movie will follow one snail's quest to become a race driver worthy of making the cut at the Indy 500. Like many DreamWorks vehicles before it, we're guessing that the petrolhead snail will star in a movie that adults (especially racing fans) with have no trouble watching with their kids. Check out the trailer below to see if you agree.
As for the car, we're told that it is "instrumental" in transforming Turbo from snail into racer. Helping the beastly pony car in this mighty task, is an ankle-cracking front splitter matched by a ungodly huge rear wing out back, a COPO hood and a supercharged (yes, supercharged) V8 engine making more than 700 horsepower. 24-inch wheels all the way around - 10-inches wide in front and 15-inches wide in back - should allow the "Turbo" Camaro to hook up with ease, as well.

2020 Chevy and GMC HD truck spy shots reveal LED lighting

With Chevy and GMC's 1500 series pickups just starting to roll into dealerships, our attention naturally turns to the Heavy Duty 2500 and 3500 series trucks. We've seen these HD trucks testing already, but thes latest spy photos give us our first good glimpse of the two HD trucks' headlights through some translucent camouflage, and their designs appear very interesting and quite different from each other. The 2020 Chevrolet Silverado HD looks to be getting a striking set of LED lights that flank the grille. A previously released teaser image of the truck shows that the front lighting elements are split by a bulky wing that branches out from a big, upright chrome face, and both top and bottom units seem to incorporate LED slashes. If you look closely at the images, you can easily make out the Chevrolet script cut into the grille's top edge. Amidst a bevy of Chevy test trucks was one lone GMC model in a dually configuration, and the Sierra HD also appears to have some LED accent lighting up front. Unlike the boomerang-shaped Chevy LEDs, GMC's version sports a shoulder-like right angle of light bars. Assuming these are production-level lighting units, it seems the Sierra HD will stick pretty close to the face of GMC's latest light-duty pickup truck. We're still waiting for confirmation on what range of powertrains will be available in GM's next-gen HD trucks, but we're sure there will be both gasoline- and diesel-burning engines on the ordering sheet. We expect to hear official details on the trucks sometime soon.
