v2.5.0.2 - Balancing savegames

[jelledc]

here is my savegame (still ongoing, now 1957), started in 1930: it feels like my cars are really overpowered already, 1200cc 3 inline with torque and rev rating zero, fuel economy 65 and all emission ratings on 10 just to get the power down, still makes 94hp and 151nm torque
