Oh yah, i remember what you were refering to now. It was before they release the car. In the beginning, they were saying that the Max. will be 260HP and the Spec-V will be 180HP. This is months before they were release. Then a month or so before they release the car, they changed both to 175hp and 255 hp. They didn't state a reason, but the official # were 255 and 175.
About the Q45, I always thought it was rated @ 340HP. I could be wrong, but i'm pretty sure it's 340HP.
