im with you on this one sleek stratos. ive long thought too that fuel should play a part in gran turismo. it wouldnt overly complicate anything, and it would add another level of strategy to the game. gran turismo 5 (if they call it that) will definately debut on the playstation 3, and with all that extra processing power, sony should try and simulate more of the actual workings of a car. fuel consumption is a great idea, and should be included, because apart from the car itself, it is one of the most important factors in actually moving the vehicle. ive often wondered if sony have toyed with the idea of a fully simulated fuel management system, or even better a fully simulated engine with wear and tear affecting overall performance. it would be a fantastic of you could 'krypton tune' your car virtually dont you think? to appease the casual gamers, there could always be a switch on the options menu to turn it on or off, just like manual or automatic transmission. personally if it was included, i would be willing to use the option - the more simulation the better in my eyes. one last thing, dont you think that it would be great to have some diesels in the game?
