IMSA and the TUDOR United SportsCar Championship are, once again, having an identity crisis. Heading into the 2014 season, IMSA needed to find a way for ALMS LMP2 and Grand-Am Daytona Prototype entries to coexist. A season and a half later, things on track are looking pretty good. While there are still balance of performance issues to be finessed (top-speed, pace on restarts), both platforms have proven to be capable of topping timesheets and winning races.
The 2017 season will bring sweeping changes to both ACO and IMSA prototype regulations. IMSA has once again found themselves tasked with reaching a compromise between stakeholders with vastly differing objectives. For the FIA and ACO, the 2017 regulation changes will try to steer the category towards a more financially accessible future. In stark contrast to their European associates, IMSA may well be fighting to keep prototype racing viable in the North American market.
