In motor racing, BTC Touring was the set of new regulations for the British Touring Car Championship (BTCC) introduced in 2001 BTCC, after the demise of the Supertouring category. The cars were based on standard bodyshells, but were allowed significant modifications to turn the car into a racecar and differentiate it from the Super Production class that would run alongside BTC Touring in the 2001 BTCC.

For the 2003 Rolex Sports Car Series season, the Grand American Road Racing Association (GARRA) announced that they would stop support of their two premier open cockpit classes, known as SRP-I and SRP-II. These cars, mostly modified from Le Mans Prototypes, were technologically advanced and could reach high speeds, specifically on the Mulsanne Straight at the 24 Hours of Le Mans.

From 2017 forward, a new generation of Daytona Prototypes, branded Daytona Prototype International (DPi), has been replacing the original tube-framed Daytona Prototypes.

A Daytona Prototype International (DPi) is a type of sports prototype racing car developed specifically for the IMSA WeatherTech SportsCar Championship, as their top class of car, acting as a direct replacement, and spiritual successor of the Daytona Prototypes. They are named after the main series event, the Rolex 24 at Daytona. The class made its racing debut at the 2017 24 Hours of Daytona.
