A SNAIL Sanctioned event - Open to all Welcome to the DriveTrain Challenge (DTC). We are a tuning prohibited event that requires all participants to use four different drivetrains and uses the Performance Point system in Gran Turismo as a limiter on the nights racing. Here is how it works. Each week a PP Limit is chosen. This weeks PP limit can be found by clicking on the Calendar image above. You must choose 4 cars that the total combined PP value does not exceed the limit for the event. Each car can only be used in one race. Additionally you must use 1 of each of the following drivetrains in your lineup: FF- Front Engined/Front Wheel Drive 4WD - 4 Wheel Drive (any engine position) FR - Front Engined/Rear Wheel Drive MR/RR - Mid Engine(or Rear Engined)/Rear Wheel Drive When Calculating the PP total the value is for a un-tuned, non power limited car with an oil change. This is what is referred to as the Known PP* value for the car. The list of Known PP values can be found by clicking on the car image above. The Event Qualifying and the first race take place at a track chosen by last weeks runner up. This weeks qualifying track can be found by clicking on the Calendar image above. The next three races will take place at tracks chosen by the winner of the previous race. The winner can pick from the eligible track list that can be found by clicking on the track image above. Additionally the list is broken up in to three groups. Each group can only have one track chosen from it in a nights event. Additional rules and guidelines can be found here. Thats it. I hope you come give it a try! Joby *Some cars have a modified PP Please refer to this list for more details.
