The Full List at a Glance

How Many Car Brands Start With O?

Approximately 15 major car brands start with O, with 4 currently active in global markets: Opel, Omoda, ORA, and Oettinger (as a performance tuner). The remaining 11 are defunct but remain relevant to collectors, historians, and automotive enthusiasts. No other letter in the alphabet has such a stark divide between iconic mass-market brands and ultra-rare specialist manufacturers.

Opel Germany’s Pioneer Brand (1862–Present)

Opel is the most famous and longest-running car brand that starts with O. Founded in 1862 in Rüsselsheim, Germany, Opel began as a sewing machine manufacturer before producing bicycles in 1886 and its first automobile in 1899.

Opel’s History From Sewing Machines to Stellantis

Opel’s automotive journey began with the Opel-Lutzmann in 1899. A partnership with French automaker Darracq (1900–1907) accelerated production. General Motors acquired Opel in 1929, and the brand became Europe’s largest automaker for decades. 

In 2017, PSA Group (now Stellantis) purchased Opel from GM, returning it to European ownership. Today, Opel produces the Corsa, Astra, and Mokka under Stellantis alongside sister brands Peugeot and Vauxhall.

Iconic Opel Models: Corsa, Astra, Insignia

The Opel Corsa remains one of Europe’s best-selling superminis, with over 14 million units sold since 1982. The Astra dominated the compact family car segment, while the Insignia served as Opel’s flagship executive sedan. The Manta coupe (1970–1988) became a cult classic, and the GT roadster (2007–2009) revived the brand’s sports car aspirations.

Where Is Opel Sold Today?

Opel operates primarily in Europe, with strong markets in Germany, the UK (as Vauxhall), and France. Since the Stellantis merger, Opel has expanded its electric lineup with the Corsa-e and Astra Electric, aligning with the EU’s 2035 combustion engine ban. The brand no longer sells in Russia, China, or North America.

Oldsmobile America’s 107-Year Legacy (1897–2004)

Oldsmobile was the oldest surviving American car brand when GM shut it down in 2004. Founded by Ransom E. Olds in Lansing, Michigan, the brand produced America’s first mass-produced car the Curved Dash — in 1901.

Why Oldsmobile Was Called the “Engineering Pioneer”

Oldsmobile earned its reputation through continuous innovation. It introduced the first fully automatic transmission (Hydra-Matic, 1940), the first high-compression overhead valve V8 (Rocket, 1949), and the first modern front-wheel-drive car (Toronado, 1966). The Rocket V8 became the foundation for GM’s muscle car era, powering the 442 and Cutlass Supreme.

The Rise and Fall of America’s Oldest Car Brand

Despite 107 years of production, Oldsmobile struggled with brand identity in the 1990s. GM’s badge-engineering strategy blurred distinctions between Oldsmobile, Buick, and Pontiac. Sales declined from over 1 million annually in the 1980s to just 266,000 in 2003. GM announced the closure in 2000, and the final Alero rolled off the Lansing line on April 29, 2004.

Most Collectible Oldsmobile Models Today

The 1968–1972 442 (four-barrel carburetor, four-speed manual, dual exhaust) commands $50,000–$100,000 in concours condition. The 1966 Toronado — America’s first modern FWD car — and the 1970–1972 Cutlass Supreme convertible remain highly sought after. The Aurora (1995–2003) represented Oldsmobile’s final attempt at premium positioning.

Omoda The New Chinese SUV Brand Taking Over Europe

Omoda is one of the fastest-growing car brands starting with O. Launched by Chery in 2022, Omoda targets young buyers with bold SUV designs and aggressive European pricing.

Omoda’s Rapid Global Expansion (2022–2025)

Omoda debuted in Russia and the Middle East in 2022 before entering Europe in 2023–2024. By 2025, Omoda operates in over 30 countries, including the UK, Spain, Italy, and Australia. The brand’s strategy relies on Chery’s established manufacturing base, one of China’s largest exporters with Omoda serving as the premium-facing sub-brand.

Omoda 5 vs Omoda E5: Petrol vs Electric

The Omoda 5 (petrol) features a 1.6L turbocharged engine producing 186 hp, priced from approximately £24,000 in the UK. The Omoda E5 (electric) delivers 201 hp from a single motor, with a 61 kWh LFP battery and 267-mile WLTP range — competing directly with the MG4 and BYD Atto 3. Both models share a futuristic exterior design with a distinctive diamond-pattern grille.

Is Omoda the Same as Chery?

Omoda is a sub-brand of Chery, similar to how Lexus operates under Toyota. While Chery handles engineering and manufacturing, Omoda manages branding, marketing, and dealer networks. This structure allows Omoda to position itself as a standalone brand in Europe while leveraging Chery’s economies of scale.

ORA Great Wall Motor’s Electric Cat

ORA (Open, Reliable, Alternative) is GWM’s dedicated electric brand and one of the most intriguing car brands starting with O. Founded in 2018, ORA names its vehicles after cat breeds the Good Cat, Funky Cat, and Lightning Cat — creating instant memorability.

ORA’s “Cat” Naming Strategy Explained

GWM chose feline names to differentiate ORA in a crowded EV market. The Good Cat (hatchback) targets urban commuters, the Funky Cat (compact SUV) appeals to families, and the Lightning Cat (coupe) delivers performance. This naming convention has generated significant social media engagement, particularly in European markets where ORA launched in 2022–2023.

ORA 5 SUV: The 2025 Game-Changer

The Ora 5 a compact crossover SUV launched in China in December 2025 and entered Australia in April 2026. It features a 150 kW electric motor, 58.3 kWh LFP battery, and up to 360 miles CLTC range. The Ora 5 represents GWM’s shift from quirky hatchbacks to mainstream SUV formats, directly challenging the BYD Atto 3 and MG ZS EV.

ORA vs Omoda: Two Chinese O-Brands Compared

Both brands compete in Europe’s affordable EV segment, but ORA leads on electric heritage while Omoda offers lower entry pricing.

OSCA, Oreca & Orca The Racing Trinity Starting With O

Three O-brands dominated motorsport: OSCA (Italian sports cars), Oreca (French endurance racing), and Orca Engineering (Liechtenstein supercars).

OSCA: The Maserati Brothers’ Forgotten Masterpiece

OSCA (Officine Specializzate Costruzione Automobili) was founded in 1947 by the Maserati brothers after selling their original company to the Orsi family. OSCA produced the MT4 racing model and the 1600 GT coupe by Frua, Michelotti, and Zagato. The brand closed in 1967 after MV Agusta’s acquisition. Today, OSCA 1600 GTs command $200,000+ at auction.

Oreca: From French Racing Team to LMP1 Legend

Founded in 1973 by Hugues de Chaunac, Oreca evolved from a racing team into a prototype manufacturer. The Oreca 05 (2015) and Oreca 07 (2017) dominated the LMP2 class at Le Mans, with the 07 remaining the category’s reference chassis through 2025. Oreca also develops the Acura ARX-05 for IMSA competition.

Orca Engineering: Liechtenstein’s Supercar Secret

Orca Engineering produced just 7 cars between 2003 and 2007 in Liechtenstein. The C113 coupe used an Audi twin-turbo V8, while the R113 roadster remained a concept. The SC7 exclusive model and the Beck LM800 prototype represented the brand’s engineering ambition before financial constraints forced closure in 2012.

The Forgotten O Brands: Oakland, Overland, Olcott & More

Beyond the famous names, several obscure car brands starting with O shaped automotive history.

Oakland Motor Car Company (1907–1931)

Founded in Pontiac, Michigan, Oakland aimed to offer luxury cars at affordable prices. GM acquired Oakland in 1909 to compete with Buick. The brand’s most notable achievement was the Model 50 V8 (1916), but it couldn’t survive the Great Depression. GM replaced Oakland with the Pontiac brand in 1931.

Overland Automobile Company & the Willys Connection

Overland (1903–1926) began in Terre Haute, Indiana, before John North Willys acquired it in 1908. The Overland 42 (1910) became an iconic model, and the company evolved into Willys-Overland — the manufacturer of the original Jeep during WWII.

Oltcit: Romania’s Brief Automotive Dream

Oltcit (1976–1991) produced compact cars in Craiova, Romania, in collaboration with Citroën. The Oltcit Club shared mechanical components with the Citroën Visa but featured unique Romanian styling. Production ended after the fall of communism and Romania’s transition to a market economy.

Ohta, Otomo & Ogle: Asian and British Rarities

• Ohta Jidosha (1922–1957): One of Japan’s oldest automakers, known for the Tokyo Taxi PA model
• Otomo (1924–1927): Experimental Japanese manufacturer absorbed by Gorham
• Ogle Design (1954–1962): British design house that produced the SX1000 sports car before focusing on industrial design

Luxury & Sports Cars That Start With O

Several O-brands occupy the luxury and performance segments, from classic Italian sports cars to modern German tuners.

The O.S.C.A. 1600 GT by Zagato represents the pinnacle of O-brand luxury, with values exceeding $300,000 for concours examples. 

The Orca C113 had it reached production would have competed with Porsche and Ferrari in the 2000s supercar market. The Oldsmobile Toronado (1966) remains the most accessible luxury O-car, with clean examples available from $15,000.

Oettinger: The German Tuner That Elevates VW Group Cars

Oettinger Sportsystems (founded 1946) is Germany’s oldest automotive tuner. Specializing in Volkswagen, Audi, SEAT, and Škoda vehicles, Oettinger offers performance-enhanced engines, suspension upgrades, and custom interiors. 

Unlike mass-market brands, Oettinger operates as an official OEM partner, meaning its modifications retain factory warranty coverage.

O.S.C.A. 1600 GT: A Six-Figure Italian Classic

The OSCA 1600 GT (1959–1963) was bodied by Italy’s greatest coachbuilders: Frua, Michelotti, Zagato, Fissore, and Vignale. With a 1.6L twin-cam engine producing 125 hp and a sub-900 kg curb weight, the 1600 GT delivered genuine sports car performance. 

Only 128 units were produced across all body styles, making it one of the rarest Italian classics available.

Common Mistakes When Researching O Car Brands

Avoid these errors when researching car brands that start with O.

Don’t Confuse Omoda With ORA (Different Companies)

Omoda is owned by Chery; ORA is owned by GWM. Both are Chinese, both start with O, and both sell electric SUVs in Europe — but they are direct competitors, not related brands. Omoda focuses on SUV formats, while ORA began with quirky hatchbacks.

Why “O.S.C.A.” and “OSCA” Are the Same Brand

O.S.C.A. (with periods) and OSCA (without) refer to the same Italian manufacturer. The periods reflect the Italian abbreviation style (Officine Specializzate Costruzione Automobili), but both spellings appear in historical records and modern auction listings.

The Opel-Vauxhall Relationship Explained

Opel and Vauxhall are sister brands under Stellantis. In the UK, Opel models are rebadged as Vauxhall (e.g., Vauxhall Astra = Opel Astra). The cars are identical mechanically, with only badges, steering wheel position, and trim differences. This relationship confuses many buyers researching “car brands that start with O” because Vauxhall starts with V.

O Brand Logos: Visual Guide & Design Evolution

Car logos that start with O reveal fascinating design stories.

How Opel’s Lightning Bolt Logo Has Changed Since 1862

Opel’s logo evolved from a simple “O” in the 1860s to the Zeppelin-inspired circle (1910), then the blitz (lightning bolt) inside a ring (1964–present). The lightning symbolizes speed and electrical energy fitting for Opel’s modern EV transition. The current logo, introduced in 2016, features a sleeker 3D blitz.

Oldsmobile’s Rocket Symbol: An American Icon

Oldsmobile’s Rocket logo introduced in 1948 alongside the Rocket V8 — became one of America’s most recognizable automotive emblems. The rocket symbolized post-war optimism and technological progress. Even after Oldsmobile’s closure, the rocket remains a cultural icon, appearing on merchandise and in classic car restoration communities.

Modern O Brand Logos: Omoda vs ORA Design Language

Omoda’s logo features a diamond-shaped “O” with sharp angles, reflecting its SUV-focused, bold positioning. ORA’s logo uses a circular “O” with a cat-eye motif, reinforcing its feline naming strategy. Both logos avoid traditional automotive imagery (wings, shields) in favor of tech-forward minimalism, a hallmark of modern Chinese brand design.
