When you spot a sharp geometric diamond shape on the front grille of a vehicle, you're looking at Renault, the prominent French automotive manufacturer. However, car emblem history gets a bit more crowded than people realize. Another major global automaker, Mitsubishi, uses a distinct three-diamond cluster. Knowing which brand uses a diamond logo depends on whether you mean a single prominent rhombus or a triple-diamond emblem.
Let's look straight at the primary contender, how these logos came to be, and what they actually represent.
Renault and the Single Diamond Logo
The single geometric diamond—often styled as a rhombus—belongs exclusively to Renault. If you see a modern hatchback, SUV, or electric vehicle in Europe or other international markets with sleek, sharp lines forming a diamond shape, it's a Renault.
The emblem didn't start out as a diamond. When Louis Renault founded the company in 1899, the badge featured intertwined initials. Over the next two decades, the shape shifted due to manufacturing realities and design trends. As extensively documented in detailed coverage by Reuters, the implications are widespread.
How the Renault Diamond Was Born
In 1925, Renault needed a fresh look that fit the sharp, angular lines of its vehicle hoods and accommodated the front-mounted horn grille mandated by regulations. Designers integrated the grille shape into a rhombus, creating the first official diamond emblem.
Over the decades, the logo evolved through several notable phases:
- The 1925 Rhombus: The debut of the angular diamond shape set against horizontal hood lines.
- The Vasarely Redesign (1972): Famed artist Victor Vasarely modernized the badge into a clean, three-dimensional striped diamond without text.
- The Modern Flattening (2021): Renault unveiled a minimalist, "flatified" optical-art version of the diamond to suit digital screens and modern electric vehicles.

Mitsubishi and the Three-Diamond Emblem
If the logo you're thinking of features multiple red diamonds clustered together, you're looking at Mitsubishi. While it isn't a single large rhombus like Renault's badge, it's universally known as a diamond-based emblem.
The name "Mitsubishi" translates directly from Japanese: mitsu means three, and hishi (which changes to bishi in compound words) means water chestnut or diamond shape, referring to the rhomboid geometric form.
The Family Crest Origins
The Mitsubishi symbol originated from a combination of two family crests in the 1870s. Founder Yataro Iwasaki used the three-leaf oak crest of his family and the three-tiered water chestnut crest of his feudal lord. Merging these concepts produced the iconic three-diamond arrangement. Each red diamond represents a core corporate value: integrity, reliability, and success.
Other Brands With Diamond-Adjacent Badges
People often confuse other geometric car emblems with diamonds. Clearing up these common mix-ups helps you identify vehicles quickly on the road.
Chevrolet
Chevrolet uses a badge commonly called the "bowtie," but many casual observers mistake its slanted, four-sided polygon shape for a tilted diamond or cross. Founded in 1911, William C. Durant introduced the bowtie design, though its exact origin remains a subject of debate within automotive lore.
Dodge
Older Dodge models and performance lines have used various crests, shields, and geometric shapes. While Dodge historically relied on ram horns and text, its modern performance arm, SRT, utilized aggressive angled shapes that casual viewers sometimes misidentify as abstract diamonds.
Borgward
A historical German car brand that experienced a revival, Borgward featured a distinctive diamond-shaped badge divided into quadrants with red and silver coloring. While rarer today, vintage Borgward models frequently pop up in classic car collections.

Common Mistakes When Identifying Car Logos
When trying to spot car brands by their emblems, drivers often make a few predictable errors:
- Confusing Renault with Chevrolet: Because both badges feature four-sided geometric shapes, people unfamiliar with European imports sometimes mix up the Renault rhombus with a stylized Chevy bowtie.
- Assuming all diamonds mean luxury: Unlike luxury badges that use golden shields or prancing animals, diamond logos belong to mass-market and mainstream global manufacturers.
- Overlooking vintage iterations: Many brands altered their logos drastically between the 1920s and 1980s. A Renault from 1930 looks vastly different from a modern 2026 electric model, even though both use the diamond concept.
