At highway speeds, tyre noise and wind noise are noticeable, so the sound insulation of the Isuzu D-MAX is average. While the new generation has improved in this area, there's still a gap compared to passenger cars, especially when the pickup bed is empty and cabin resonance is more prominent.
喺高速公路行駛時，Isuzu D-MAX嘅輪胎噪音同風噪都比較明顯，隔音表現一般。雖然新一代車型喺呢方面已經有所改善，但同私家車相比仍然有距離，尤其係尾斗冇載貨時，車廂共鳴聲會更突出。
