Pfister is heavily inspired by Porsche AG. The badge is shaped after a shield divided between a red and a gold section, just like Porsche's iconic logo (the latter being based on the Stuttgart coat of arms). The logo font also closely resembles the one formally used by Porsche.
Pfister Design posters and articles can be seen in certain stores in GTA V, referencing the Porsche Design Group. A Pfister Design store can be found in Rockford Hills, mirroring the existence of a real-life Porsche Design store in Beverly Hills. The player can purchase Pfister-branded polo-shirts and watches in GTA Online .

- "Pfister" is another piece of adult humour by Rockstar, as its pronunciation is similar to "fister", thus alluding to the sexual practice of fisting.
- In GTA San Andreas, a Hispanic female pedestrian will sometimes ask "Have you ever driven a Pfister?" when in a conversation with a pedestrian. Other pedestrians may also ask "Is that a Pfister?"  when complimenting CJ's car. This could mean that the brand was planned to be introduced before GTA IV with the scrapped system of vehicle brands (as seen in carcols.dat).
- In GTA V, whenever the player buys a pink car from a website, the car will be "Pfister Pink" instead of "Hot Pink".
- The announcement image for the Pfister 811, presented on the Rockstar Newswire, follows a design pattern often seen in modern Porsche adverts: image over a white background, the slogan in black, the name of the car in smaller grey letters under the slogan, a small description near the image and the logo in the bottom .
