Cadillac will expand its range of high-performance Blackwing models

Cadillac proved the American sport sedan isn't dead when it introduced the Blackwing variants of the CT4-V and the CT5-V (pictured) in February 2021. Launched to denote a short-lived V8 engine, the nameplate will appear on other go-fast members of the company's range in the coming years, but there's at least one model it will steer clear of. "Blackwing is reserved for really the pinnacle, the purest expression of performance and track capability, and that's what it's going to stand for going forward. [The CT4-V Blackwing and CT5-V Blackwing] won’t be the last Blackwing cars that we do, but you wonÂ’t see one on every vehicle. ItÂ’s not appropriate. I couldnÂ’t imagine doing an Escalade-V Blackwing," said Cadillac engineering boss Tony Roma in an interview with enthusiast site GM Authority. His comments are reassuring, because they confirm that Cadillac won't water down the Blackwing badge by putting it on sporty-looking models that are more show than go. What's next remains up in the air. The CT4 and the CT5 are Cadillac's only sedans as of writing, so the next Blackwing-badged model will either be an electric car, a crossover, or both. Regardless, it should arrive as a truly track-capable hot rod developed for hardcore enthusiasts. For others, Roma also suggested more V-badged cars are in the pipeline, though he stopped short of listing the models the emblem will appear on. Demand for quick crossovers is growing steadily in America, so it's not difficult to imagine an XT4-V, for example. And, an unverified report published in February 2021 claims the Escalade's 6.2-liter V8 will soon receive a 200-horsepower bump thanks to a factory-backed, dealer-installed supercharger. If the rumor is accurate, the 600-plus-horse Escalade could be the V-branded model that Roma alluded to in the interview. "The V-Series lineup has expanded," he said. "You're going to see more of that in the future. We're going to do more V-Series. It's important to our brand, and you'll see it on other products." Related video:

Next Cadillac Escalade interior will have Mercedes-like screens

Not too long ago, we thought we got a glimpse at the next-generation Cadillac Escalade's interior. But as we have learned from the spy photographer who took it, those are actually for a different full-size GM SUV, probably the GMC Yukon. How can we know this? Well, that same photographer caught this SUV, and it has a fancier interior and a key Cadillac interior piece that proves this is actually the Cadillac interior. The big difference with this interior is the instrument cluster and infotainment system. The previous SUV we saw had a pretty conventional interior with plenty of buttons, a screen at the top of the center stack, and an instrument cluster under a plastic hood. On this presumed Cadillac SUV, it has one large monolith containing screens for instruments and infotainment. It's very much like what you'll find in Mercedes-Benz models. Unlike in Mercedes cars, this bank of screens appears to have some curve to it, orienting everything toward the driver. Besides the fancy screens that point to Cadillac, the shifter also clinches this as the Cadillac interior. It's the same monostable lever found in the latest Cadillacs such as the XT6 and CT5. Much of the rest of the interior has been pretty well covered. But we can tell that Cadillac is using some nice wood trim that appears to stretch across the dashboard. The dash itself also looks as though it will be rather low and minimalist. Like past Escalades, this will probably share most of its mechanicals with the Tahoe/Suburban, meaning it too will be making the long overdue switch to independent rear suspension. It will also likely continue to offer the 6.2-liter V8 and 10-speed automatic transmission as the only powertrain choice. We should see the new SUVs in the next couple of years.

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.
