Diesel engines have long been popular in bigger cars and have been used in smaller cars such as [[supermini]]s in Europe since the 1980s. They were popular in larger cars earlier, as the weight and cost penalties were less noticeable.<ref name="AG125">{{Cite journal |last=Pirotte |first=Marcel |date=1984-07-05 |title=Gedetailleerde Test: Citroën BX19 TRD |trans-title=Detailed Test |journal=De AutoGids |language=nl-be |location=Brussels, Belgium |volume=5 |page=6 |ref=AG125 |number=125}}</ref> Smooth operation as well as high low-end torque are deemed important for passenger cars and small commercial vehicles. The introduction of electronically controlled fuel injection significantly improved the smooth torque generation, and starting in the early 1990s, car manufacturers began offering their high-end luxury vehicles with diesel engines. Passenger car diesel engines usually have between three and twelve cylinders, and a displacement ranging from 0.8 to 6.0 litres. Modern powerplants are usually turbocharged and have direct injection.<ref name="Reif_2014_11" />

Diesel engines do not suffer from intake-air throttling, resulting in very low fuel consumption especially at low partial load<ref name="Reif_2014_23" /> (for instance: driving at city speeds). One fifth of all passenger cars worldwide have diesel engines, with many of them being in Europe, where approximately 47% of all passenger cars are diesel-powered.<ref name="Tschöke_2018_1000" /> [[Daimler-Benz]] in conjunction with [[Robert Bosch GmbH]] produced diesel-powered passenger cars starting in 1936.<ref name="Tschöke_2018_10" /> The popularity of diesel-powered passenger cars in markets such as India, South Korea and Japan is increasing (as of 2018).<ref name="Tschöke_2018_981" />
