In every aspect of heavy duty performance this engine has set benchmark standards for fuel efficiency, driveability and reliability. The ISMe has a long standing reputation for excellent transient response and higher overall refinement, enabling it out perform larger engines. Structurally, the ISMe is at the forefront of heavy-duty design with a life-to-overhaul goal of one million km. Yet despite all this inbuilt strength the engine weighs only 940 kg, offering a substantial payload advantage.
