The Upfront 924 was designed by Larry Wood. It is based on the Porsche 924, a front-engine sports car from the 1970s and 80s.
The casting was first released in 1979. Model 2500-a with Blackwall (BW) wheels is from that debut year.
The casting features a large, non-opening hood scoop. The name "Upfront" refers to the car's front-engine layout, which was unusual for a Porsche at the time. The initial release was typically in yellow with graphics.
It is a contemporary of other Porsche models like the P-911 and P-928, but represents the more accessible, front-engine entry in Porsche's lineup.
It was released in many colors throughout the late 70s and early 80s. A notable variation is the "Extras" release from 1983.
