Be Careful Around Hennessey’s H1000 Cadillac CT5-V Blackwing!

Hennessey is taking the already impressive Cadillac CT5-V Blackwing to a whole new level with its H1000 package, turning this sports sedan into an absolute powerhouse. Straight out of the factory, the CT5-V Blackwing is no slouch, boasting a supercharged 6.2-liter V8 that delivers an already impressive 668 hp and 659 lb-ft of torque.

You have the option of a six-speed manual or a 10-speed automatic transmission, both of which allow the Cadillac to sprint to 60 mph in around 3.5 seconds and reach an exhilarating top speed of 205 mph.

Hennessey decided to take things to a whole new level by thoroughly modifying the LT4 V8 engine. This involves porting the cylinder heads, tweaking intake and exhaust valves, enhancing lifters and pushrods, optimizing the heat exchangers, adding long-tube stainless steel headers, and fine-tuning the ECU calibration. The result? A mind-boggling total of 1,000 hp and 966 lb-ft of torque!

In recent dyno tests, a CT5-V Blackwing H1000 showcased its might, pumping out an impressive 841 hp and 765 lb-ft of torque to the rear wheels. According to Hennessey, this modified H1000 Cadillac CT5-V Blackwing can accelerate to 60 mph in just about 2.5 seconds, blaze through the quarter mile in 10.1 seconds, and exceed the top speed of 205 mph!

John Hennessey describes this H1000 upgrade as a natural choice for the CT5-V Blackwing, substantially boosting power without sacrificing drivability. This transformation positions the Cadillac as the fastest combustion-only luxury sedan globally—a true highlight in a segment that's evolving rapidly.
