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.
