## Resource

In this “Evening With a Legend” episode, we interview Mark Raffauf, IMSA’s Senior Director of Competition, tracing how IMSA’s early relationship with the ACO grew from the 1970s through the creation of GTP, the split from FIA Group C’s fuel-formula approach, and the IMSA-driven development that helped shape cars like the Porsche 962. Mark recounts 1980s GTP’s manufacturer battles and behind-the-scenes antics, then explains the 1990s shift to World Sports Car, Ferrari’s 333 SP, and how rule changes at Le Mans affected competitiveness. He details IMSA’s organizational split that led to ALMS and Grand-Am, the rise of Daytona Prototypes, and today’s cost-control challenges. The conversation culminates in a deep discussion of Balance of Performance, LMDh vs hypercar sustainability, lift-and-coast strategy, and the need for a common future platform beyond 2030, while emphasizing Le Mans as a global mega-event.
