Cadillac specialist, D3 Group, have released images of this all-black, tuned 2013 ATS sports sedan. The already aggressive silhouette is accentuated, while retaining integrity to its original design. A full line-up of body kit wraps the vehicle from front to rear, improving its menacing aesthetic. On top of that, the lowered stance and large rims bring the four-door closer to the tarmac. At this moment, the modification is restricted to cosmetic upgrades; however, the team is working on performance kits to increase the horsepower as well. These parts should start shipping sometime around the beginning of 2013.
