Cadillac planning more Vsport models

There's a new intermediate class of luxury performance cars emerging. Audi has been doing it for years with its S-line bridging the gap, in many cases, between the standard fare and the full-on RS performance range. BMW's getting in on it with the M Sport line slotting in below the full M models. And now Cadillac is joining the fun with its Vsport offerings.
Models like the CTS Vsport and XTS Vsport are packing a new 3.6-liter twin-turbo V6 with 410 or more horsepower (along with bigger wheels and brakes) to slot in between the standard model and any impending V variant. Well, it appears Cadillac isn't about to stop there.
Speaking with The Detroit News, Cadillac product chief Hampden Tener revealed that, based on the response to the XTS Vsport, the brand is planning more Vsport models. He did not, however, indicate which would be the next to get the slightly sportier treatment. With the full ATS-V expected to pack a version of the same engine powering the aforementioned XTS and CTS Vsport models, an ATS Vsport would have to pack a smaller engine to fit in below. That only leaves the SRX crossover, Escalade SUV and the upcoming ELR hybrid. Food for thought.

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.

2020 Cadillac CT5 revealed, will replace the CTS

Between the end of most of Cadillac's sedan offerings and the launch of the underwhelming XT6 crossover, things were looking dreary at the American luxury brand. But now we get an exciting surprise in the reveal of the 2020 Cadillac CT5 sedan. It's a clean, and arguably conservative-looking sedan, but there are a number of things that have us intrigued. The sedan is clearly the CTS replacement, since the name falls just below the flagship CT6 sedan. Under the hood are two familiar Cadillac engines, a 2.0-liter turbocharged inline-4 and a twin-turbo 3.0-liter V6. Power numbers haven't been announced, but expect each to make similar power to the current CTS: 268 horsepower and 295 pound-feet of torque for the four-cylinder and 420 horsepower and 430 pound-feet of torque for the V6. Rear drive and all-wheel drive are available, and both engines get a 10-speed automatic transmission. The car also adopts the trim level scheme introduced by the XT4 and XT6 crossovers, which means there are just two choices, Sport and Luxury. The Sport model, pictured in gray, has a more aggressive front fascia and dark taillights, while the Luxury model, shown in burgundy, has a more demure appearance and classic red taillights. We only get a glimpse of the interior, and it shows the latest electronic gear shifter shared with Cadillac's recent crossovers, along with a physical knob for interacting with the infotainment system. Cadillac announced that the car will make its public debut at the New York Auto Show, and it will be built at the Grand River factory in Lansing, Mich. We expect to get more details and images of the car when it's revealed at the show.
