Python class instance: laps = 0

The challenge is saying that something is wrong with my laps attribute, and I'm not sure why

racecar.py 
class RaceCar:

    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = 0


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


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

I don't see anything wrong with "laps", but I do see another issue:

In the "run_lap" method, the fuel update calculation references "self.length", but there's no instance attribute by that name. The formula should be using the passed-in argument "length" instead.
