Launched in 1979, the OM422 was initially derived from the earlier OM402 engine found in models like the 1626S. By increasing the cylinder bore from 125 mm to 128 mm and the stroke from 130 mm to 142 mm, Mercedes created a robust 14.6-liter workhorse. The naturally aspirated OM422 was groundbreaking, shifting its torque peak down to just 1,200 rpm, giving drivers incredible flexibility without needing to constantly downshift on inclines. om422 engine workshop manual
