What Happened to the 387?

I believe the 387 was replaced with the 587, and then that was discontinued and replaced with the 579 ultraloft. Not sure on when they replaced the 387 or 587 but I believe the 579 ultraloft went into production of July this year.
PETERBILT LAUNCHES NEW MODEL 579 ULTRALOFT

 

The original Peterbilt 387 was a coal truck, made from 1975 to 1987.

The name was re-used in 1999 and made through 2009 at the Denton and Nashville plants. It was designed to be more aerodynamic than its predecessors, and had two sleeper lengths, with a raised roof or mid roof, and a day cab option; a glider kit was optional.

It was eventually superceded by the Peterbuilt 587, which was EPA SmartWay certified and had the same cab and sleeper, but with a redesigned hood , headlights, front grille and bumper.

A variety of wheels were available — stud-piloted disc wheels (both regular and heavy-duty), PHP-20/Budd UniMount-10/WHD-8 series, and cast spoke wheels.

Transmissions were made by Spicer, Fuller, and Meritor. Drivers had a variety of computer-driven alarms, to show system faults, low air or oil pressure, and high engine oil, transmission oil, or coolant temperature.

 

I had no idea about the 1975 version of the 387, looked it up and sure enough it’s real. Real heavy duty looking truck too. Was that the only case of Peterbilt reusing a model name?

 

Yes it was as far as I know.

 

June 30 2017 was the last call for the 587. 587 sales dropped in favor of the 579 so the model was discontinued.
