Season 2 will feature pit stop strategies
You can choose between either 1 stop or 2 stops.
2 stop cars start the race with enough fuel to make it to the 1/3 distance, where they pit and put in enough fuel to make it to the 2/3 distance, where they pit again and put in enough fuel to make it to the end. So they are faster then 1 stop cars because they're carrying less fuel but they have to pit one more time. Also their tires are always fresh.
1 stop cars start the race with enough fuel to make it to the halfway point where they make their only pitstop. Because they start the race with more fuel and take on more fuel at their first pitstop they are slower then 2 stop cars but pit one less time.
1 stop cars have to go longer on their tires, but this only affects them at the end of the race. While they may be on older tires then 2 stop cars heading into their first pitstop, they will be carrying much less fuel then 2 stop cars at that point in time which will make up for their old tires. However at the end of the race when both strategies are at similar fuel levels, 2 stop cars will have fresher tires and a speed advantage.
Which strategy is ideal depends on a number of variables
