Since the team’s 2004 arrival with the first-gen CTS-V sedan it has amassed 33 wins, 88 other podium, 25 pole positions and taken home five Drivers’ championships and five Manufacturers’ crowns. The program has featured nearly a dozen drivers, including Johnny O’Connell, Michael Cooper, Ricky and Jordan Taylor, Andy Pilgrim, Max Angelelli, Ron Fellows, John Heinricy, Olivier Beretta and Lawson Aschenbach, with Cooper and Jordan Taylor claiming this year’s SprintX title.

Mark Kent, GM’s director of motorsports competition, said: "Throughout 11 years of competition with Cadillac Racing in the Pirelli World Challenge Series, we have taken tremendous pride in our successes…  We also have taken tremendous pride in the level of technology transfer that has occurred between the Cadillacs competing on track and their showroom counterparts.  This technology transfer has helped make the Cadillac ATS-V and CTS-V production models very track-capable and athletic."

Added Rich Brekus, global director of product strategy for Cadillac: "In 2018, we will take a pause in Pirelli World Challenge as we focus completely on our effort in prototype sportscar racing. However, we maintain a regular and open communication with Greg Gill, the World Challenge CEO, and hope to one day return to the Series in some form."

A reason for the program’s end was not given, although the manufacturer has left the door open for a possible future return. Any possible future return would unlikely come with the current-generation ATS-V.Rs, which were built to FIA GT3 specification but never raced in the hands of customer teams, or outside of PWC.
