VinFast Funding and Investment

VinFast's funding story is different from that of a typical venture-backed startup.

The company has received substantial financial support from Vingroup, its affiliates and external lenders to fund vehicle development, manufacturing facilities and international expansion.

According to VinFast's annual report, around $17 billion had been deployed to support operating expenses and capital expenditure since 2017 by Vingroup, related parties and external lenders.

This capital has helped the company build manufacturing capacity, develop its EV lineup and enter international markets.

VinFast's strategy requires significant investment because automobile manufacturing involves large expenses for factories, research, supply chains, distribution and after-sales services.

Therefore, its funding should be viewed mainly as long-term industrial investment rather than a series of conventional startup funding rounds.

BYD Funding and Financial Strength

BYD has a different financial profile because it is a large established technology and automotive company with significant revenue from its operations.

The company generated approximately RMB 804 billion in revenue in 2025, while net profit was around RMB 32.6 billion.

BYD's large scale gives it the ability to invest heavily in research, manufacturing and international expansion.

The company also has a large engineering and research workforce. Its investment in batteries, electric drivetrains, vehicle platforms and charging technology has helped it develop products across different price segments.

Rather than relying primarily on outside funding to build its business, BYD has increasingly been able to finance expansion through its large operating business and access to capital markets.

VinFast Products

VinFast has developed a wide range of electric mobility products.

Its passenger vehicle lineup includes models such as the VF 3, VF 5, VF 6, VF 7, VF 8 and VF 9. The company is also developing MPVs and commercial vehicles.

VinFast has expanded beyond passenger cars into electric buses and scooters.

This broad product strategy allows the company to target different segments rather than depending on a single vehicle.

In Vietnam, smaller and more affordable models have also played an important role in sales growth.

The company delivered 196,919 electric vehicles in 2025, more than double its deliveries from the previous year.

BYD Products

BYD has one of the broadest EV portfolios among major electric vehicle manufacturers.

Its range includes compact cars, sedans, SUVs, luxury vehicles, buses and commercial vehicles. The company also sells plug-in hybrid models through its DM technology.

BYD's product strategy allows it to compete across different price points.

The company has also developed its own battery technologies, electric platforms and charging systems. Its Blade Battery is particularly important to its EV strategy.

BYD has continued investing in faster charging technology as well. Its newer charging technology is designed to significantly reduce the time required to recharge an EV under suitable conditions.

VinFast Growth

VinFast's recent growth has been driven mainly by the rapid expansion of its electric vehicle business.

In 2025, the company delivered 196,919 EVs, representing growth of more than 100% from the previous year.

Its revenue also increased significantly. VinFast reported approximately VND 90.4 trillion in revenue in 2025, up more than 100% year over year.

Vietnam remains an important market for the company, but international expansion is becoming increasingly important.

India is one of the key markets in this strategy. VinFast is building manufacturing capacity in Tamil Nadu and has been working on its sales and service network in the country.

The company is also expanding in Indonesia and the Philippines, creating a wider Southeast Asian footprint.

BYD Growth

BYD operates at a much larger scale.

The company sold approximately 4.6 million new energy vehicles in 2025, including battery-electric and plug-in hybrid vehicles.

Its international business has also expanded rapidly, with BYD selling vehicles across many markets outside China.

BYD's growth is supported by its manufacturing scale, broad product range and control over important technologies.

The company has also continued increasing its investment in research and development. This includes batteries, vehicle platforms, driver-assistance technologies and charging systems.

Its large production network gives BYD an advantage when it comes to serving different international markets.

VinFast vs BYD: Manufacturing Strategy

Manufacturing is an important difference between the two companies.

VinFast is still building its global manufacturing footprint. Its strategy includes establishing production facilities in important markets such as India while expanding its existing manufacturing operations.

BYD already operates at a much larger manufacturing scale. The company has production facilities in China and has also expanded manufacturing activities internationally.

BYD's vertical integration also means it has greater control over several parts of the vehicle supply chain.

VinFast, meanwhile, is focusing on building production capacity while expanding its international sales and service networks.

Key Differences Between VinFast and BYD

The biggest difference is scale.

BYD is already one of the world's largest new energy vehicle manufacturers, while VinFast is still in a rapid expansion phase.

The companies also differ in their business models. VinFast is primarily an EV-focused automaker, whereas BYD operates across batteries, EVs, hybrids, electronics and clean-energy technologies.

Their international strategies are also different. VinFast is building a global footprint from a smaller base, while BYD is expanding an already large international business.

Another difference is technology ownership. BYD has invested heavily in internally developed battery and vehicle technologies, while VinFast's strategy has focused more heavily on vehicle development, manufacturing expansion and partnerships.

VinFast vs BYD: What the Comparison Shows

VinFast and BYD are both important examples of how Asian EV manufacturers are expanding internationally, but they are at different stages of development.

VinFast is focused on building an international EV brand and expanding its manufacturing footprint. Its rapid delivery and revenue growth show how quickly the company is scaling from its Vietnamese base.

BYD, on the other hand, has reached a much larger operating scale. Its combination of EVs, hybrids, batteries and other technologies gives it a diversified business model.

For consumers, investors and industry observers, the comparison highlights two different approaches to competing in the global EV market: VinFast's expansion-led strategy and BYD's scale and vertical-integration strategy.

Which Brand Has a Stronger Business?

• BYD has a much larger global automotive business, broader product portfolio, extensive manufacturing scale, and strong vertical integration through its battery and EV technology operations.
• VinFast is a newer EV-focused automaker that is still expanding internationally and building manufacturing capacity outside Vietnam.

So, based on scale, established global presence, product breadth, and manufacturing experience, BYD is currently the stronger brand/business. VinFast's strategy is more focused on EV-only expansion and building a global brand.
