6.8 Liter Commercial Engine

Solenoid controlled common rail injection system delivers 350PS & 300PS And 120.3 kg·m of torque from the 6.8 liter in-line 6 cylinder engine.
The broad flat torque curve proves Hyundai SeasAll’s diesel development capabilities are world-class and beats performance of competition’s comparable models.
Economy is assured by the state-of-the-art fuel Management system featuring Common Rail Direct Injection (CRDI).
