The circuit will host the new generation of GTP cars — IMSA’s label for LMDh Hypercars — from Porsche, BMW, Acura and Cadillac. Support races will include the Michelin Pilot Challenge, which will run into the night to prepare for the SportsCar Championship race the following year.
Douglas Boles, IMS president, said that the existing Jumbotron screens at the speedway were so bright that little additional lighting would be needed. He revealed that fans would uniquely be able to camp in the infield, giving it a feel of a true sports car event.
Roger Penske, owner of the circuit, has previously said that he would also like to host a round of the World Endurance Championship (WEC), and has had talks with officials. However a second US race, in addition to Sebring, is not thought to be a priority for WEC.
It will be the first time in nine years that the series has speeded at the circuit. Sebastian Bourdais and Alex Popow won the first IMSA event in 2012, while Christian Fittipaldi and Joao Barbosa won the final IMSA Brickyard Grand Prix in 2014.
