Hennessey Performance has released a new video showcasing its HPE1000 upgrade for the Cadillac CT5-V Blackwing. The video features drag races between the super sedan and a stock Chevrolet Corvette Z06.

The Corvette Z06 is equipped with a naturally aspirated 5.5-liter V8 engine, producing 670 horsepower and 460 pound-feet of torque. This allows the mid-engine supercar to accelerate from 0 to 60 miles per hour in 2.6 seconds. However, Hennessey’s HPE1000 upgrade package for the Cadillac diminishes the Corvette’s numbers.

The CT5-V Blackwing comes with a supercharged 6.2-liter V8 engine, generating 668 horsepower and 659 pound-feet of torque. However, with Hennessey’s upgrade, the Cadillac’s output increases to 1,000 horsepower and 966 pound-feet of torque.

In the drag races, the Cadillac easily outperforms the Corvette despite the sedan’s heavier weight of 4,123 pounds compared to the Corvette’s 3,686 pounds.

Hennessey has made numerous upgrades to the Cadillac’s engine, including ported cylinder heads, an HPE camshaft, new valves, lifters, pushrods, and a larger supercharger. The upgrade kit also includes a high-flow air intake, larger heat exchangers, and long-tube stainless-steel headers. Hennessey’s engine management software ensures that all the upgrades work together seamlessly.

According to Hennessey, the upgrades enable the Cadillac to reach 60 miles per hour in 2.5 seconds, which is 0.1 seconds quicker than the Corvette and a full second faster than the stock CT5-V Blackwing. The tuned Cadillac can complete the quarter-mile in a claimed 10.1 seconds and has a top speed of 205 mph.

Cadillac recently updated the CT5 sedan for the 2025 model year, introducing subtle styling changes without modifying the powertrains. The updated CT5 offers a standard turbocharged 2.0-liter four-cylinder engine producing 237 horsepower, or a twin-turbo 3.0-liter V6 engine generating 335 horsepower. Details about the updated CT5-V and CT5-V Blackwing models will be revealed later.

Hennessey has not disclosed the price of the HPE1000 upgrade package, but it is expected to exceed six figures. The CT5-V Blackwing has a starting price of $93,390, including the $1,395 destination charge. The HPE1000 kit comes with a two-year, 24,000-mile warranty.
