The Mercedes-Benz 190D was a four-door sedan produced from 1983 until 1993 that was most commonly powered by a 2.5-liter diesel engine that produced between 91 and 94 horsepower depending on the model year. A 2.2-liter diesel and 2.5-liter turbodiesel engine were also available in North America in some years.
Early Mercedes-Benz 190D models released for the 1984 and 1985 model year in North America used a 2.2-liter engine that produced 72 horsepower, rather than the 2.5-liter that was offered in subsequent years. The 2.5-liter turbodiesel version of the 190D was only available in 1987. The turbodiesel produced a peak 125 horsepower and 168 foot-pounds of torque, making it nearly 25 percent more powerful than the standard model. Despite the additional power, the turbodiesel-powered 190D took almost 12 seconds to accelerate from 0 to 60 miles per hour. Much of the vehicle's sluggish performance can be attributed to its high curb weight, as the 190D weighed approximately 3000 pounds despite being considered a compact sedan.
The 190D designation was also used for an older Mercedes-Benz model produced from 1958 to 1961. This version of the 190D was powered by an in-line-four diesel engine. These older cars are often distinguished from the modern 190D in discussion by using the internal production numbers for each car. The older 190D was internally referred to as the W120, while the more recent incarnation was the W201.
