Hennessey is not any stranger to the world of high-performance autos. The American tuning firm takes some already vastly potent machines and takes them to complete new heights. The newest to obtain the Hennessey remedy is the Cadillac CT5-V Blackwing. The Blackwing is already Cadillac’s strongest manufacturing automobile, and it's now pushing 1,000 hp due to the varied adjustments that Hennessey has made to it.
