Hotter Cadillac CT5-V could use the CTS-V's 6.2-liter V8

Cadillac is in the final stages of testing the high-performance variant of the CT5, prototypes are racking up miles all over the world, and a recent report sheds light on the engine screaming between its punched-out fenders. It's a V8, to no one's surprise, but it's not the twin-turbocharged, 4.2-liter unit many believed the sedan would use. Sources familiar with Cadillac's product plan told Car & Driver the hotter CT5 — whose name hasn't been revealed yet — will receive an updated version of the supercharged 6.2-liter V8 that powered the mighty CTS-V. It developed 640 horsepower in the firm's last German-bashing super-sedan, though where engineers will peg the CT5's output remains to be seen. It will roast the rear tires through a paddle-shifted automatic transmission. The publication explained Cadillac chose the 6.2-liter because it's more compact than the 4.2-liter Blackwing engine it developed for the CT6. The former features a pushrod design, while the latter gets twin overhead cams that make it taller and wider. The CT5 is a new model, but its Alpha platform is older than Cadillac's newest V8. Cadillac hasn't announced what will power the flagship CT5. The model is tentatively due out in showrooms before the end of 2020, so we expect to learn more about it in the coming months. Seeing it in the metal for the first time during the 2020 Detroit Auto Show in June isn't entirely out of the question. What's next? If the report is accurate, the much-hyped Blackwing may end up being an orphan engine. It was developed specifically for the Cadillac brand, and inaugurated by the CT6-V that recently went out of production. The many rumors claiming General Motors will put the engine in other models to recoup its investment are falling like dominoes. It won't fit in the CT5, so there's no reason to believe it will end up in the smaller CT4; its flagship version will likely arrive with a twin-turbocharged, 3.6-liter V6 borrowed from the ATS-V. An earlier report claims the next-generation Escalade won't use the Blackwing, either, because making it fit would cost too much. Looking beyond Cadillac, the only General Motors-owned brand that could use the Blackwing is Chevrolet, since we can't imagine the GMC Yukon will get it if the Escalade doesn't. The Tahoe/Suburban duo is off the table, too.

Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

Cadillac Escalade reportedly getting 200-hp bump from supercharger

Cadillac is preparing to supercharge the Escalade, according to a recent report. The body-on-frame General Motors SUVs that it shares its basic underpinnings with are allegedly in line to receive a big increase in power, too. Released for the 2021 model year, the fifth-generation Escalade eschewed downsizing and launched with a 6.2-liter V8 as its standard engine. It develops 420 horsepower and 460 pound-feet of torque when it's naturally aspirated, and Motor Trend learned from an anonymous source that the optional supercharger will increase the first figure to anywhere between 600 and 625. The eight's torque output will undoubtedly go up, too. The supercharged Escalade won't outgun the sold-out Dodge Durango SRT Hellcat, which gets 710 horses, but it will pack a serious punch. It doesn't sound like the V8 will require significant modifications to handle the extra power because the supercharger kit will likely be installed by dealers, not on the assembly line. This strongly suggests that it's more of a bolt-on job than one that requires taking the engine out and apart to install stronger connecting rods and forged pistons, for example. ECU tweaks will be part of the package, too, and the fuel delivery system may require some upgrades. Interestingly, Motor Trend learned from Texas-based Hennessey that the SUV's ECU is locked to tuners, which adds credibility to the report. Motorists who want more power will need to go through official sales channels, then. Bigger brakes and a firmer suspension won't be part of the package — at least not yet. The same source outlined a true high-performance evolution of the body-on-frame behemoth that will be quicker and tighter to drive. Oddly, it's not being developed by the engineers in charge of Cadillac's V-branded models, according to the report. If the report is accurate, we'll learn more about the supercharged Cadillac Escalade in the coming months, and it might go on sale in time for the 2022 model year. Expect the supercharger to come with a four-digit price tag. Chevrolet's Tahoe/Suburban and GMC's Yukon/Yukon XL will reportedly be available with a supercharger, too.
