Known as the "Sirius Diesel", the 4D65 has the same dimensions as the 4G62 . It was available either naturally aspirated or turbocharged (with an air-to-air intercooler), and was used in most Mitsubishi diesel passenger cars in the eighties and beginning of the nineties. It was developed specifically to be transversally installed in front-wheel-drive cars, unlike the preceding 4D5-series which remained in production for commercial vehicles. The 1.8 TD power figures are comparable to those of the 22 percent larger, 2.3 liter 4D55, with more low-down torque and while being much smoother. The cast-iron block was typical for Mitsubishi, but unusual for diesel engines, in being equipped with
