Hennessey H1000 Dials Cadillac CT5-V Blackwing up to 1000 HorsepowerJune 27, 2023
Few people would ever find the 668 horsepower Cadillac CT5-V Blackwing to be lacking in power, but for those who desire a little more grunt, famed tuner Hennessey Performance has released a 1000 horsepower version of Cadillac’s super sedan.
Called the H1000, this ballistic Blackwing shaves a full second from the standard car’s 3.5 second 0-60 run, and completes the quarter-mile run in just 10.1 seconds. Hennessey has not provided a top speed yet, but promises “well over 200 miles per hour.” In addition, the H1000 is backed by Hennessey’s 2-year, 24,000 mile warranty.
Performance has been kicked up a notch thanks to a number of key upgrades. First, the Blackwing’s LT4 V8 engine is outfitted with ported cylinder heads, better intake and exhaust valves, and more enhanced lifters and pushrods. These parts are joined by oversized heat exhangers and long-tube stainless steel headers. A high-flow supercharger replaces the factory unit, paired off with a Hennessey Engine Management Calibration (HEMC) upload.
No word on pricing yet, but the standard 2024 CT5-V Blackwing starts at $94,890 with destination, and we expect the H1000 to be quite a bit more.
