F-Astor Junior is essentially a Formula Ford 1600 style car with more power and a little less weight. With 180 hp but weighing only 395 kg, the car is surprisingly quick around various kinds of circuits even without any downforce generating wings. Yet for the same reason, it's capable of relatively high top speeds for an entry-level open-wheel car. Measured in-game top speed is 244 km/h on my test oval, and speeds up to ~210 km/h can be reached on conventional circuits. All this combined makes the car suitable for various driving styles and close racing!
Not much more to say, hope you like it
