Car makes and models beginning with the letter I

Several car manufacturers and their models start with the letter I. The most recognizable is Infiniti, the luxury brand owned by Nissan, which makes vehicles like the Q50 sedan and QX60 SUV. Isuzu, a Japanese manufacturer, produces trucks and SUVs including the D-Max pickup and MU-X sport utility vehicle. Isdera is a small German sports car maker known for high-performance vehicles. Iso was an Italian manufacturer that built sports cars in the 1960s and 1970s, though the company is no longer in operation.

Beyond full brand names, some individual car models start with I across different manufacturers. Examples include the Chevrolet Impala, the Hyundai Ioniq (an electric and hybrid vehicle line), and various models from the brands listed above. The letter I is less common in automotive naming than letters like C, H, or S, so the list of options is shorter than you might find for other starting letters.

Key Takeaways

  • Infiniti is a Japanese luxury car brand that produces sedans, crossovers, and SUVs sold worldwide.
  • Isuzu manufactures commercial trucks and consumer SUVs, with a strong presence in Asia and other markets.
  • Isdera and Iso are specialty manufacturers—Isdera still produces limited-run sports cars, while Iso stopped production decades ago.
  • Individual car models from other makers, like the Chevrolet Impala and Hyundai Ioniq, also begin with I.

Infiniti: Nissan's luxury division

Infiniti launched in 1989 as Nissan's premium brand, competing with other luxury manufacturers like Lexus and Acura. The brand focuses on sedans, coupes, and crossover SUVs aimed at buyers who want higher-end features and performance than mainstream brands offer. Current Infiniti models include the Q50 and Q60 sedans, the QX50 and QX60 crossovers, and the larger QX80 SUV.

Infiniti vehicles typically come with more powerful engines, upscale interior materials, and advanced technology features than their Nissan counterparts. The brand is sold in North America, Europe, the Middle East, and Asia, though availability varies by region. If you are shopping for a luxury vehicle, Infiniti sits in the mid-to-upper price range compared to other premium brands.

Isuzu: Trucks and commercial vehicles

Isuzu is a Japanese manufacturer founded in 1916 that specializes in commercial trucks, pickup trucks, and sport utility vehicles. The company is known for durability and is widely used in commercial fleets across Asia, Africa, and other regions. The D-Max is Isuzu's popular pickup truck sold in many countries, while the MU-X is a three-row SUV designed for families and commercial use.

Isuzu vehicles are often chosen for work purposes because of their reputation for reliability and low maintenance costs. The brand has less presence in North America than in other parts of the world, though some models are available in the United States. Isuzu also manufactures engines and components for other vehicle makers.

Isdera: German high-performance sports cars

Isdera is a small German manufacturer founded in 1969 that builds limited-production sports cars and supercars. The company is known for hand-built vehicles with powerful engines and distinctive styling. Models have included the Spyder, the Imperator, and the Commendatore, each produced in very small numbers.

Isdera vehicles are expensive and rare, aimed at collectors and enthusiasts who want exclusive, high-performance machines. The company remains active but produces only a handful of cars per year. If you encounter an Isdera on the road, it is a specialty vehicle rather than something you would see regularly.

Iso: Italian sports car maker (historical)

Iso was an Italian automobile manufacturer that operated from 1953 to 1974, known for building sports cars and GT vehicles. The company produced models like the Isetta (a small bubble car), the Grifo (a high-performance sports car), and the Lele (a grand tourer). Iso vehicles were often powered by American V8 engines paired with Italian design and craftsmanship.

Iso is no longer in operation, so you will only find these cars on the used market or in collections. The brand has a following among classic car enthusiasts because of its distinctive design and performance heritage. If you are interested in vintage sports cars, Iso models are considered collectible.

Other car models starting with I

Beyond full brand names, several individual models from other manufacturers begin with I. The Chevrolet Impala is a full-size sedan that has been produced on and off since 1958, with a current generation available. The Hyundai Ioniq is a line of electric and hybrid vehicles designed for fuel efficiency and lower emissions. The Infiniti QX Inspiration is a concept vehicle that previewed future Infiniti design direction.

Some regional or older models also start with I—for example, the Isuzu Impulse was a sports car produced in the 1980s and 1990s. The letter I is uncommon in car naming, so the total number of models starting with it is smaller than for more popular letters.
