The Veloster N in "N mode "is not street friendly unless it a smooth road..... It's quite radical and harsh unless your street racing and at that it's still better in Sport+ mode for street use, with some custom tweaks in the "Custom mode." That being said, when are you going to purchase one?
The video author says, you can change rev match on the fly but he doesn't explain, it has to be done thru the Custom Mode or by changing drive mode on the fly, it's not that easy. You just can't push the rev match button, as it's either on or off with the button alone. The on three levels of the rev mode are changed in separate drive modes or you can turn it off all together. White in Normal Drive Mode, Yellow in Sport Mode and Red in N Mode. Or as I said before, use the rev match button alone to turn it off or on. He didn't explain it very well.
