Hennessey Launches Tuned Cadillac CT5-V Blackwing Making 1,000 HP

Hennessey has a major power upgrade for the Cadillac CT5-V Blackwing. It overhauls the engine to produce a prodigious 1,000 horsepower and 966 pound-feet of torque, which is a whole lot more than the stock 668 hp and 659 lb-ft.

The supercharged 6.2-liter V8 receives quite a bit of work to achieve the additional power. Hennessey adds ported cylinder heads, an HPE camshaft, and new parts for the valves, lifters, and pushrods. A larger supercharger replaces the stock unit. Other tweaks include installing oversized heat exchangers, high-flow air intake, and stainless steel headers. Revised engine management software makes the most of these new parts.

Hennessey claims its 1,000-hp Cadillac CT5-V Blackwing can reach 60 miles per hour in roughly 2.5 seconds – versus around 3.5 seconds in stock form. The higher-powered sedan can cover the quarter-mile in 10.1 seconds. The tuner only says the top speed tops the standard model's 205-mph top speed.

Beyond the power upgrade, Hennessey leaves the CT5-V Blackwing alone. For example, it still rides on the Magnetic Ride Control 4.0 suspension. The factory offers carbon-ceramic brakes as an option, and they weigh 53 pounds less than the standard steel rotors.

The Blackwing's cabin features a 12.0-inch digital instrument cluster with three display modes: Tour, Sport, and Track. There are also features like launch control and a Performance Traction Management system.
