I was driving around in GTA IV: TBoGT and most of the time I drive the semi trucks (Mostly the Phantom) and when people try to attack me, I just start to chase them. Sometimes, they have cars that are slower than the truck, but most of the time, they are in some super jumped up super car or super bike. Now, I know its a semi truck, but I also know for a fact that they accelerate alot faster than the game suggests. I mean the truck in the game has 720HP and I know for a fact that if a diesel engine that size has that much horsepower, I know it has over 2,000 lbs-ft of torque. In case you don't know what that means, it means that, in the beginning of every gear, will surge ahead from the burst of torque being sent to the rear tires. I know how the computers in these trucks are programmed. The computer that controls the gearbox is designed to send all the available torque to the tires to keep the truck moving. With no load on the back of it, it will easily keep up with most 400 HP muscle cars. I think this is something that Rockstar should look into for the next game. Please provide your input below.
