hmm dude I have tested it my self, I own one Vti Oriel prosmatic eagle eye and once the speed hit at 180KM/H, the car engine was smooth but it just doesnt go above that as gear was not providing it the necessary torque, where if its a manual Vti Oriel, it can easily cross 200 or even 210, same is the issue with its acceleration too, and also fuel economy is much much better with manual ..
