Top 10 Largest Car Rental Companies In The World 2026

The global car rental industry is a massive, multi-billion dollar market dominated by a handful of powerful holding groups and regional champions. These companies manage fleets that number in the hundreds of thousands, operate across dozens of countries, and serve millions of customers each year. As of 2026, the landscape continues to shift, with traditional giants holding their ground and newer players expanding aggressively. Below, we rank the 10 largest car rental companies in the world based on fleet size, global reach, and market influence.

How We Ranked These

Our rankings are based on publicly available fleet data, geographic presence across countries and territories, and annual revenue reports from the companies themselves and industry analysts. We weighed total fleet size most heavily, as it is the clearest measure of operational scale. International reach and brand portfolio diversity were secondary factors. Data is drawn from company filings, NerdWallet analyses, and mobility sector reports from the mid-2020s.

The List Of The Top 10 Largest Car Rental Companies In The World 2026:

1. Enterprise Holdings (Enterprise Rent-A-Car, National, Alamo)

Enterprise Holdings is the undisputed largest car rental company in the world. As of 2022, its combined fleet across the Enterprise Rent-A-Car, National Car Rental, and Alamo Rent A Car brands exceeded 2.1 million vehicles. That figure is roughly four times larger than the fleet of its closest competitor, Hertz, and dwarfs every other operator in the industry.

The company operates in more than 90 countries, with a particularly dense network of neighborhood and airport locations in North America and Europe. Enterprise built much of its business on insurance replacement rentals, giving it a steady stream of customers that other companies cannot match. Its three brands target different segments: Enterprise focuses on local and corporate rentals, National targets business travelers with its Emerald Club program, and Alamo caters to leisure tourists. This multi-brand strategy gives Enterprise Holdings a dominant position across nearly every rental category.

2. Hertz Global Holdings (Hertz, Dollar, Thrifty)

Hertz Global Holdings operates the Hertz, Dollar, and Thrifty brands with a combined fleet of approximately 547,400 vehicles in 2022. The company has a presence in more than 145 countries and territories, making it one of the most internationally recognized names in the industry.

Hertz has long been associated with airport rentals, where it maintains a strong footprint. The company has also made headlines for its aggressive push into electric vehicles, placing large orders with Tesla and other manufacturers to modernize its fleet. While Hertz emerged from bankruptcy in 2021 and has been working to stabilize its finances, its brand recognition and global scale keep it firmly in the number two position. The Dollar and Thrifty brands give it additional reach in the value-conscious segment of the market.

3. Avis Budget Group (Avis, Budget, Payless, Zipcar)

Avis Budget Group manages a portfolio that includes Avis, Budget, Payless, and the car-sharing network Zipcar. Its average rental fleet numbered around 600,000 vehicles in 2022, placing it just slightly behind Hertz in overall size. The company operates in more than 180 countries, giving it one of the widest geographic footprints in the industry.

Avis is the group's flagship brand, known for premium service and long-standing relationships with airlines and corporate travel programs. Budget targets price-sensitive customers, while Payless serves the ultra-budget segment. Zipcar, which the group acquired in 2013, gives Avis Budget Group a foothold in the growing car-sharing market. The company is particularly strong in Europe and North America, and its diversified brand strategy helps it capture customers across different price points and trip types.

4. Sixt SE

Sixt SE, based in Germany, has grown rapidly from its European roots into a genuine global competitor. The company operates more than 3,500 locations across over 100 countries as of the mid-2020s. In 2025, Sixt was voted the number one rental car company in the United States in the USA Today 10Best Readers' Choice Awards, a reflection of strong customer satisfaction and brand perception.

Sixt differentiates itself with a high proportion of premium and luxury vehicles in its fleet, including BMW, Mercedes-Benz, and Audi models. The company also invests heavily in its digital experience, with a well-regarded mobile app and online booking platform. While its global fleet is smaller than those of Enterprise, Hertz, and Avis, Sixt's rapid expansion into North America and its strong quality rankings make it a formidable number four.

5. Europcar Mobility Group

Europcar Mobility Group is the leading car rental provider in Europe, with a network that extends to more than 140 countries through company-owned operations and franchise agreements. The group operates multiple brands, including Europcar for core rentals, Goldcar for low-cost options, and Ubeeqo for mobility services.

Europcar targets both leisure and corporate customers, and its extensive presence in European airports and city centers gives it a dominant position on the continent. While its fleet volume is below that of the big three U.S.-based groups, its European dominance and global partner network make it one of the largest players outside North America. The company has also been expanding its flexible rental and subscription offerings to compete with newer mobility services.

6. Localiza Rent a Car S.A. (Localiza & Unidas)

Localiza, headquartered in Brazil, is the largest car rental company in Latin America. The company operates in more than 10 countries across the region and manages a fleet of several hundred thousand vehicles. Its integration of Unidas, a major competitor, has further strengthened its position in the Brazilian market.

Localiza serves both retail customers at airport and downtown locations and corporate clients through long-term fleet management and leasing. This dual focus gives it a diversified revenue base that is less dependent on tourism than some of its competitors. While Localiza is less global than the top European and U.S. groups, its regional dominance and very large fleet justify its number six ranking.

7. ALD Automotive | LeasePlan (Ayvens)

ALD Automotive and LeasePlan, which merged and now operate under the Ayvens brand, are best known for full-service leasing and fleet management. However, they also operate substantial short-term rental and flexible mobility products that compete directly with traditional car rental companies.

The combined portfolio of Ayvens exceeds 3 million vehicles globally, with operations in more than 40 countries. A significant portion of this fleet is deployed for short-term rentals, replacement vehicles, and flexible subscriptions, particularly in corporate and B2B segments in Europe. Because much of the fleet is dedicated to long-term leasing rather than traditional rent-a-car, Ayvens ranks below the dedicated giants. Still, its massive combined fleet and global corporate reach make it a major force in the broader mobility market.

8. Movida Participacoes S.A.

Movida is one of Brazil's largest car rental and fleet outsourcing companies, competing closely with Localiza in the country's rapidly growing mobility market. The company operates airport and downtown rental locations as well as long-term fleet outsourcing for businesses, giving it a diversified revenue base.

Movida has been expanding its fleet and presence across Brazil and has begun building some regional footprint elsewhere in Latin America. Its fleet numbers in the hundreds of thousands of vehicles as of the mid-2020s. While its scale is regionally concentrated rather than global, Movida's sizeable operations in one of the world's largest automotive markets earn it the number eight spot.

9. CAR Inc. (China Auto Rental / UCAR)

CAR Inc., often known as China Auto Rental, is China's leading car rental provider. The company operates across more than 300 cities in China, with a fleet historically numbering in the hundreds of thousands of vehicles. It focuses on short-term rentals to both leisure and business travelers and has partnered with ride-hailing and travel platforms to increase its reach.

China's car rental market is enormous and growing, driven by increasing domestic tourism and a rising middle class. CAR Inc. commands a dominant position in this market, but its operations are primarily domestic with a limited international footprint. This combination of very large but mostly single-country scale supports a number nine global ranking.

10. OK Mobility (formerly OK Rent a Car)

OK Mobility started in Spain as OK Rent a Car and has diversified into broader mobility services, including subscriptions and leasing. The company has expanded across southern Europe and key tourist destinations, focusing on value-oriented rentals for leisure travelers.

OK Mobility's fleet is significantly smaller than those of the global giants, but it has been growing rapidly. The company is increasingly visible in European tourism hubs, particularly in Spain, Italy, and Portugal. Due to its rising but still modest global scale, it rounds out the list at number ten. OK Mobility represents the kind of agile, regional player that is increasingly challenging the established giants in specific markets.
