At the 2019 Baja 1000, Ford introduced the Ford Bronco R prototype with the drivetrain of the new as-yet unreleased 2021 Bronco with the intent of testing the engine, transmission and four wheel drive system to be used in the production-spec sixth-generation Bronco. The Baja 1000 was thought to be the perfect test for the new off-road vehicle Ford is producing, with 1000 miles of some of the world's roughest terrain. The 2020 race was also tougher after being delayed for 24 hours due to excessive rainfall in the days before the event. With the excessive rainfall, one of the Class One co-drivers Ford used in the race referred to it as the "Mud Bog 1000."
