That one 1 DF for the added predictor between the base model (mpg ~ 1, row 1) and the next ones, which both include numerical predictors (1 regression coeff each).

The DFs relate to the difference between consecutive models, while the SS column is about the residual squares of the model under consideration (and it remains the same as expected). The anova (or drop1 or whatever) are about comparing nested models.
