Hennessey Powers-Up Cadillac Escalade beyond Recognition

When a giant in the tuning industry like Hennessey meets the almighty Cadillac Escalade then be definitely sure that hell will break loose, the result being no other than an outstanding and outrageous tuning project.

The aftermarket specialists have recently carried out an impressive power upgrade to this Cadillac Escalade seen in the video below, the model now packing a whopping 842 horsepower, and delivering a sprint from 0 to 100 km/h in just 3.9 seconds.

This is at least what the engineers claim, and I personally believe them, since this wouldn’t be the first time they would deliver as promised.

We are not going to spoil all the fun and let you enjoy the video with the Cadillac Escalade`s new power put together by Hennessey. Also, please find below the full details of their project, released by motorward1 auto online magazine.
