There are some people on this forum whose names I will not mention that hate on hybrids and have absolutely no clue as to how they work. One guy went out of his way to assume that hybriders are fat no-lifes who just sit in their basement listening to dubstep while they hack GT5. Another blatantly told me to leave GTP because I was "hacking the game and ruining the fun for everyone". There is a MAJOR difference between hacking and save-editing. Hacking involves using a jailbroken PS3 to perform actions that cannot be done by means of simple save editing (such as being able to take Standard cars to Photo Travel and racing Karts in Career Mode) while save editing involves editing codes within your save file to trigger different outcomes, such as placing the code from a Corvette C6's engine onto the place for a Camaro Z/28's engine code. When you load up your game, your Camaro will now have a C6 'Vette engine. You do NOT need a hacked PS3 to do this!
Also if so many people are against hybridding, limit the PP or set tire wear/fuel consumption on! Duh! Crazily hacked cars will drain their fuel within 40 seconds of a race and will be limited to 49mph.
