The Packin' Pacer was designed by Larry Wood. It is based on the unconventional AMC Pacer, modified into a drag car.
It first appeared in 1977. The model number 2015 corresponds to a 1978 mainline release in the "Flying Colors" series with Blackwall (BW) wheels.
The casting features a massive V8 engine bursting through the hood and a large rear wing. The rear of the car opens up like a funny car to reveal the chassis. The name is a pun on the car's name and its powerful engine.
It is similar in concept to other "funny car" style castings with tilting bodies, but applying this to the quirky Pacer was a unique choice.
The initial 1977 Redline release was yellow. The 1978 version was typically red. It was also released in the "Super Chromes" series.
