One of my friends told me today that there's a secret engine in GT4 you get in multiplayer. He say it's neon yellow and helps upgrade your car's speed.
I haven't heard anything about this, but can anyone confirm this or is he just B.S.ing me?
complete crock of steaming BS! there is no 'secret engine'
Although if you look in options somewhere there is an option to turn on/off catch up, this improves the performance of the players car if they are lagging behind their opponent in multiplayer it certainly isn't an engine or neon yellow though
