■ L13 Engine series features

Stable Performance at High Load

The Electronic Unit Injection system delivers 500~700PS and 232~247.5kg·m of torque from the 12.7 liter in-line 6 cylinder engine.
The robustly-designed unit was specifically conceived as a light duty engine with the ability to serve the professional and commercial markets. It has stable performance at high load and responds well to sudden load changes.
Excellent power and torque in a wide rpm range proves Hyundai SeasAll’s diesel development capabilities are world-class and beats the performance of competition’s comparable models.
Economy is assured by the state-of-the-art fuel management system featuring electronic unit injectors (EUI).
