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.

Trucks and tidbits from GM's earnings report

General Motors announced this morning that 2018 was a good year for it financially, thanks in large part to the company's performance in North America, which was predicated, according to the company, on "strong pricing, surging crossover sales, successful execution of the company's full-size truck launch, growth of GM Financial earnings, and disciplined cost control." GM reported full-year income of $8.1 billion and EBIT-adjusted income of $11.8 billion. Crossover sales in 2018 were 1,034,808, an increase of 7 percent compared to 2017 deliveries. Throw in the body-on-frame SUVs and the ute number is a total 1,295,700. But let's face it: It is the trucks that really matter. The Chevy Silverado and Colorado, the GMC Sierra and Canyon. Altogether, GM sold 973,463 pickups in the U.S. in 2018. Although Ford gets bragging rights for F-Series sales, GM gets to point out that it has a greater aggregate number. An important factor regarding the trucks and the reported income is that during the last quarter, more than 90 percent of the new 2019 trucks were crew cabs (which have a higher sticker), and at GMC more than 70 percent were Denali and AT4 models (which have even higher stickers). According to reporting by Bloomberg, GM's pickup trucks combine for $65 billion in annual revenue. Clearly when the 2018 sales of the Silverado — 585,581— dwarf the combined sales of both Buick (206,863) and Cadillac combined (154,702), pickups are what matter to the overall health of the company in a way that it is difficult to otherwise achieve. The "disciplined cost control" is something that is very much in the public eye right now, as the company is taking out thousands of its workers, and there is still the "unallocated" plant situation and other plants that will remain under capacity. The numbers in GM's earnings report probably made Unifor members' heads explode in consternation, coming fresh off their Super Bowl ad: " GM, you may have forgotten our generosity, but we'll never forget your greed." But there are a couple of curiosities in the full GM earnings release. One is that so far as its autonomous efforts go, it mentions only that (1) in the first quarter of 2018 Cruise introduced a production-ready autonomous vehicle, and (2) Cruise attracted $5 billion in external capital from SoftBank and Honda. Not a whole lot of love for autonomy. Good thing they have the trucks to fund the program, to say nothing of the external capital.

2013 Chevy COPO Camaro announced with two new engines and manual option

Chevrolet is following up the 2012 COPO Camaro with another limited run of the drag-strip-ready production car for 2013. Ditching the superchargers, the 2013 COPO Camaro can only be equipped with one of three naturally aspirated V8 engines, and other new features include the option of a manual transmission, new front springs, some minor styling changes and a lower starting price of $86,000. All cars are designed to abide by the rules of the NHRA's Stock Eliminator or Super Stock classifications, depending on in which series buyers wish to enter their Chevrolet Camaro.
Returning for 2013 is the 427-cubic-inch V8 producing 425 horsepower, but the new engines include a 325-hp 350-CID V8 and a 375-hp 396-CID V8. Buyers can select to purchase all three engines, and each will be matched with the sequence number of that car; the track-only COPO cars will not have vehicle identification numbers and can't be registered for street use.
Chevrolet is also offering unique enthusiast-specific options such as a COPO Build Book and the opportunity for owners to help assemble their car's engine at the Chevrolet Performance Build Center in Wixom, MI.
