The Hyundai i30 N DCT version features three exclusive functions. N Grin Shift (NGS): Press the "NGS" button on the steering wheel for 20 seconds of maximum power output, followed by a 40-second cooldown. N Power Shift (NPS): Adds a jolt during upshifts under hard throttle. N Track Sense Shift (NTS): Automatically selects optimal gears for track driving, less relevant for Hong Kong.
