I haven't seen another thread discussing any possible changes to drag coeficient and aero in general yet, and after some car testing I did today I wanted to put this up for discussion. Just bought the F40 in GT6 and set it up just as I had it in GT5. 472hp, stock gearing, stage 3 weight reduction to get it down to that early F40 1100-1200kg weight range. A twin plate clutch fitted because real life cars came with one. Now the top speed of this car is supposed to be around 200mph and in GT5 that was certainly the case. It would almost achieve this speed in 4th before just being able to pull it's 5th gear, so tall was the gearing. And yet, in GT6 this car pulls right through all its gears and does over 370km/h!! What gives? PD has not changed displayed ratios at all in the car settings section. They are the same as they were in GT5, and are the correct F40 ratios despite many wanting to argue in other threads that they are not. The car had an accurate top speed before and now it's just not accurate for a stock car, way too fast. Has anyone else noticed that the cars in general are more slippery in GT6 or something? I'm going to do more testing with other cars but for the moment I can only assume that PD has not modeled drag very well in GT6 or something. Your thoughts everyone?
