The American tuners from Hennessey have made a living by modifying Cadillac’s top models. This time the chosen one was Cadillac CTS-V, also named Black Diamond. The tuning package mostly features exterior design and styling for this Cadillac, Hennessey deciding to let the performance part untouched. As we surf through the car specifications, we can spot some incredible design changes occurring at this Cadillac, but nothing can compare with the black paintjob specially chosen by Hennessey. The paintjob is something unique today, because of the spectral silver pigment that makes the paint look almost 3D. For an improved sport feeling, Hennessey also changed the transmission to manual. Also, on the design you can choose for several improvements such as Recaro seats and black rims. For power improvements you can have a new pipe system along with the V700 package. This CTS-V Black Diamond is only available for the moment at the Cadillac dealers.
