I was reading where the 300D Turbo 3.0 liter was the fastest diesel powered passenger car when it was introduced. Of course, Mercedes-Benz has topped that with the intro of the E300 Turbodiesel a few years back.

According to this source, it claimed a top speed of 129 MPH for the '87 300D Turbo. Considering horsepower, torque, and aerodynamic drag, this figure sounds just about right.
