I think the farthest you can go with typealias and generics is to create an alias of a specialized type, such as:

typealias SportsCar = Cars

If you need a different name for the same generic type, you can just subclass it:

class SportCars : Cars {}

it's not exactly an alias (you cannot use Cars when SportCars is expected, but the opposite is possible), but in a "controlled" environment it can work. I wouldn't use myself though.
