In Automobilista 1, you could set different performance and reliability characteristics for different skins. This lead to mods that had realistic differences between cars. However this seems to be missing in AMS 2. The only thing that makes modded drivers different in new mods is differences in their talent files. Thats all well and good for realistic results but because that doesn't affect the player, the player can win a race while their teammate finishes 24th provided they have their AI set at their level. This kinda takes away from singleplayer, as you are pretty much always aiming for wins and can't challenge yourself by picking a slow car. It would also add to career mode in the future. I do hope this feature makes a return. I don't like winning races in a Minardi.
