Having attended both F1 and IMSA races, I found some distinct differences, and you might be surprised at what I discovered.
Yes, Hendrick Motorsports once ventured beyond the oval tracks and into the world of IMSA sports car racing. So ... took a bold gamble in IMSA’s Grand Touring Prototype (GTP) series.
In 1988, Audi won the Trans-Am Series, in 1989 the Audi 90 quattro was the dominant car in the IMSA GTO ... the Audi R8 GRAND-AM celebrated a GT victory in the 24-hour race at Daytona (Florida).
The IMSA WeatherTech SportsCar Championship includes 10 races in 2025. The season begins with the Rolex 24 at Daytona this weekend.
