It isn’t the most powerful sedan sold in America, but the 2019 Cadillac CTS-V is close. With 640 horsepower, the CTS-V is the most powerful Cadillac ever, and it’s the quickest, fastest, and most powerful sedan General Motors has ever created. But if you want one, you should go out and get one while you can — after a few years on the market, Cadillac has decided to discontinue the CTS-V. After the 2019 model year, it will be replaced by a souped-up version of the brand's larger CT6 sedan. It’ll be called the CT6 V-Sport, and it’ll use an all-new twin-turbo V8 with an estimated 550 hp.
For now, the CTS-V, which is powered by a supercharged V8, is the ultimate high-performance Cadillac. It’s based on the Cadillac CTS, a mid-size luxury sedan that competes with the popular Mercedes-Benz E-Class, BMW 5 Series, and Audi A6. The CTS-V, however — which is built in Lansing, Michigan — takes on the super sedans of the class, most of which are from Germany, including the Mercedes E63 AMG, BMW M5, and Audi RS7.
