Daytona Prototype
For the 2003 Rolex Sports Car Series season, the Grand American Road Racing Association (GARRA) announced that they would stop support of their two premier open cockpit classes, known as SRP-I and SRP-II. These cars, mostly modified from Le Mans Prototypes, were technologically advanced and could reach high speeds, specifically on the Mulsanne Straight at the 24 Hours of Le Mans.
From 2017 forward, a new generation of Daytona Prototypes, branded Daytona Prototype International (DPi), has been replacing the original tube-framed Daytona Prototypes.
Daytona Prototype '2008–11
For 2008, new chassis designs were allowed to be submitted, with several companies purchasing the rights from existing entries. Lola Racing Cars, in association with Krohn Racing, purchased Multimatic's entry for the construction of a new prototype under the name Proto-Auto. Dallara later purchased Doran's entry as well, with assistance from SunTrust Racing. Cheever Racing purchased Fabcar's license and developed under the Coyote name, with assistance from former manufacturer Picchio.
