官方公佈嘅Hyundai i30 N 綜合油耗為 8.3 至 8.4 L/100km。不過香港實際路面測試（經常開 N Mode）得出嘅油耗約為 10 L/100km，油缸容量 50L，由入滿到著油燈大約可行駛 420 至 450 公里。
The official combined fuel consumption of the Hyundai i30 N is 8.3 to 8.4 L/100km. However, real-world testing in Hong Kong (with frequent use of N Mode) shows approximately 10 L/100km. With a 50-litre fuel tank, it can travel about 420 to 450 km from full to the fuel warning light.
