The OM616 2.4 liter diesel engines in the U.S. W123's were turbocharged (in other parts of the world a turbo charger remained an option). Afterwards, the OM617 3.0 liter diesel engines in U.S. Turbo diesel models will have "TURBODIESEL" on the rear of the car, but there is no designation between turbo and non-turbo in the model numbers.Įarly Diesel models offered in the United States, up to about 1981, were not equipped with turbochargers. It's good to remember that "TD" does not stand for turbo diesel and instead designates the touring models.

Within the W123 chassis, as it typical for Mercedes of the era, cars were named after their engine size, fuel type, and chassis sub-type.Įngine size was designated by its displacement in liters. W123 is the internal chassis-designation Mercedes-Benz used for their executive line of cars, manufactured between 19.
