I am unsure what I am missing here.

OK, now let's add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining attribute by length multiplied by 0.125.

Oh, and add a laps attribute to the class, set to 0, and increment it each time the run_lap method is called.

racecar.py 
class RaceCar:
    laps = 0
    def __init__(self,color,fuel_remaining,**kwargs):
        self.color = color
        self.fuel_remaining= fuel_remaining

        for key,value in kwargs.items():
            setattr(self,key,value)

    def run_lap(self,length):
        laps += 1 
        self.fuel_remaining -= (self.length* 0.125)

You're pretty close, but in the "run_lap" method where you increment "laps", it should be "self.laps".

On the other hand, the next line references "self.length" but that's not part of the class. Since it's a parameter of the method it should just be "length".
