The Grand Touring Prototype (GTP) division will form the top class of the IMSA WeatherTech SportsCar series, which kicks off with the series' marquee event, the Rolex 24 Hours at Daytona at the end of January. Cadillac and Porsche will also run these cars in the FIA World Endurance Championship, as they chase the biggest sportscar race of all – the Le Mans 24 Hours in its centenary year.
So what does the future of U.S. sportscar racing look like? Well let’s start with a different sense – what does it sound like? “My favorite thing is that I can sit here, with my back to the track, and I can tell you which car is coming by,” says IndyCar ace Colton Herta, who will be a BMW driver in the long-distance events. “I love that. It seems like a really great class, and there’s a lot of talented drivers and cool manufacturers here.”
