It’s been more than 15 years since officials with IMSA's former American Le Mans series and the Society of Automotive Engineers formed a “strategic alliance” with the Environmental Protection Agency and the Department of Energy.

Four manufacturers brought hybrids for the inaugural Grand Touring Prototype class: Acura, BMW, Cadillac and Porsche. Cadillac has stated its ambition to be all-electric by 2030, Harvey said. So it’s looking to learn, develop and “take those lessons into our EV portfolio as we move forward.”Among the greener elements to be found in the prototype cars and garage this weekend are:
