Maarten got certain things right and certain things wrong.
The base of the car, the box of the car all just mention one name: Politoys. You do not find Penny. On top of that, the references you mention are older and are not entirely up to date.
The name Penny on certain cars of the "newer" series, as per your picture, comes from the fact that certain cars have been reissued with less detail and plastic wheels.
As with many brands of toy and scale cars, it is not always as clear cut as we would like it to be. I can understand the confusion, but "Penny Politoys" on a sales site is just to attract buyers and is wrong. In 1:60ish scale you had - chronological - Penny series with rubber wheels and rather accurate casts, Politoys series, with plastic "speed wheels" and cruder casts, where certain Penny have been reissued with a less detailed cast and plastic speed wheels and then Polistil (RJ-series). Briefly, at around 2000, the name Polistil reappeared in this scale, but were in fact "RealToy"-cars with a different base. This last series, for example, is not mentioned in any of the resources online.
Once again: This particular toycar has a packaging and a base mentioning "Politoys" and the car is identified on both the box and the base of the car as "Abarth 2000". That is the answer I am sticking with.
