The engine delivered power ranging from 400 to 500 hp . In 1991, Scania introduced a 500 hp version featuring Electronic Diesel Control (EDC) , which allowed it to meet Euro 1 emission standards while producing a massive 2,130 Nm of torque .

The 143M was designed for longevity, with many units exceeding one million kilometers in service without major engine overhauls.

Scania’s engineering focused on delivering high torque at low engine speeds (roughly 1,000–1,450 rpm ), which significantly improved fuel efficiency for heavy loads. Design & Comfort: The "Streamline" Era
