A standard Cadillac CTS-V is powered by a 6.2-liter, supercharged V-8 that delivers a total of 556 horsepower, which is downright amazing for a sports sedan. From here to 1,309 horsepower is a very long way and requires tons of updates. But this is exactly the amount of power that this CTS-V, known as the most powerful one in the world, happens to have.
In order to obtain this amazing amount of power, the owner of this CTS-V updated the supercharged V-8 with a pair of Precision turbochargers, an air-to-water intercooler and heavy-duty gearbox. With these updates in tow, he now owns the most powerful CTS-V in the world — at least the most powerful one that we know of.
Check out the video to see this 1,309-horsepower CTS-V on the dyno and have a listen to this monster. It is music to our ears.
