Yep so apparently the foreign design models do at 120 kph ( 75 mph ). I'm not sure if the US models do or not. I bought mine in March and started playing with it right away including flashing the PCM / ECU. I didn't remove the VSS, or top end limiter parameter but I did see it on the screen at 163 mph. I talked to my friend who is a tech for KIA, and he told me there are two variants one at 154 and one at 163. Not sure what the difference is but I'm guessing tires ( SPEED RATING ). Only thing I see is 18 versus 19. In my opinion the 18s perform better, and of course the 19s look better. This car seems to have a lot of wheel hop in sharp turns, the 19s seem to make that worse. I have an Escort Passport MAX,,, it has a speed warning on it, at 95mph ,,,,, LOL I'd be pissed if every time I got to 75 it went off.
