Joest Racing
On 18 July 2017 it was announced that Joest Racing would take over the operation of the Mazda RT24-P Daytona Prototype International (DPi) entry in the WeatherTech SportsCar Championship for the 2018 season. Mazda withdrew from the remainder of the 2017 season in order for Joest to spearhead testing and development of the then uncompetitive DPi.
