NotImplementedError: Where is '__init__' method?

Why is the test code returning that there's no init method when there clearly is. See below:

class Car:

    wheels = 'four'
    doors = 4

    def __int__(self, brand="", model=""):
        self.brand = brand
        self.model = model


my_car = Car()
some_car1 = Car()
some_car2 = Car()

some_car1.brand = "Ford"
some_car1.model = "Mustang"

some_car2.model = "Camaro"
