Hi, I normally can answer those answer by myself, but I'm confused for some reason on this one ! Let say we have 3 car. One that does 0-100kph in : A: 4 second B: 5 second C: 6 second Would the actual difference force perceived between the B-C and A-B be the same, or the A-B would feel much more. So is the acceleration calculated in time from 0-100 offer an linear g-force difference or it exponential as the time decrease ? As you probably guessed, it to decide if the P85 would be worth it feeling wise, or the S85 would be just fine and save some hard earned cash !
