1. This 1963 magazine ad for the new ‘Jeep’ Wagoneer prominently claimed the wagon had “DRIVEPOWER”, a slogan for the Wagoneer’s new and improved and exclusive 4-Wheel Drive system. I looked to see if Kaiser Jeep attempted to trademark the term, but there’s no evidence of that at the US Patent and Trademark site. So, the use of the drivepower concept seems to have been brief.

3. This early 1964 Wagoneer Ad defines “DRIVEPOWER” as “Wagoneer station wagon’s new, improved and exclusive 4-wheel drive system” (also published in Popular Science).

4. This 1963 or early 1964 ad promoted a variety of ideas, include “DRIVEPOWER”. The ad also promoted ABC’s “The Greatest Show on Earth”, which was sponsored, at least in part, by Kaiser Jeep (see Jeep rare brochure promoting that show here).

Spotted by Maury, and according to the blurb from this page, this brochure/booklet was apparently released to some Willys-Overland employees following the purchase of Willys-Overland Motors by Kaiser-Jeep in 1953. I could only find a pic of the cover.
