Which car company's logo features three silver diamonds?

Mitsubishi is the car company whose logo features three diamonds.

The emblem is known as the Mitsubishi Three-Diamond Mark, and the company name itself reflects the design: mitsu means “three,” while hishi refers to a water caltrop or diamond-like rhombus. The mark predates Mitsubishi Motors, which was formed in 1970, because it originated with the wider Mitsubishi business group.

Its design combines imagery associated with the Tosa clan, which employed founder Iwasaki Yatarō, and the Iwasaki family crest. The stacked rhombi became a recognizable corporate symbol across Mitsubishi-affiliated companies, including Mitsubishi Motors. On vehicles, the emblem is commonly shown in red, though chrome, silver or monochrome versions can appear depending on the badge, market or promotional image.

The main quiz trap is confusing the logo’s color with its identity. Kia uses an oval or stylized lettering badge, Hyundai uses a slanted H inside an oval, and Subaru’s emblem contains stars. The distinctive three-diamond arrangement points to Mitsubishi.
