L-13 Series – L500HP, L600, L700, L460GS, L500G6

L-13 Series Engine

12.7 Litre Commercial Engine

The Electronic Unit Injection system (EU)delivers 500-700PS and 232kg-m of torque from the 12.7 litre in-line 6 cylinder engine. The robustly-designed unit was specifically conceived as an 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.

The designs optimize fuel injection and intake porting to improve combustion performance, particularly low-temperature combustion stability though lean air-fuel rationing.

This ensures that we satisfy the world’s strictest exhaust emission standards while providing the smooth, quiet and efficient power for which Hyundai SeasAll is becoming known.


Excellent power and torque in a wide rpm range proves Hyundai Seasall’s diesel development capabilities are world-class and beats the competition’s comparable models. Economy is assured by the state-of-the- art fuel management system featuring electronic unit injectors (EUI).

The electronic engine control system makes it lighter,quieter and more fuel efficient in a surprisingly compact package. The L13 provides excellent value-both at the time of purchase and during operation,it is economical and clean running-both attributes which appeal to the professional mariner.


At the core of Hyundai Seasall’s Advanced diesel technology is a focus on stability, performance, fuel efficiency and reliability: key elements which make their engines world class.
