Does Isuzu make engines for Toyota?
Not for Toyota's mainstream vehicles. While the two companies have pursued collaboration on certain technologies, Isuzu does not publicly supply engines for Toyota’s current passenger-car lineup.
Historical relationship
Over the years, Toyota and Isuzu have explored areas of mutual interest, especially around diesel engine technology and emissions control. These efforts have been described in various industry reports as technology-sharing initiatives rather than wholesale engine supply agreements. Toyota’s engines for its main models have largely been developed in-house or with other partners, while Isuzu has focused on its own diesel engines and collaborations with other automakers.
Notable points about their collaboration
Below are key elements of the relationship between Isuzu and Toyota related to engines and technology. The list captures what has been publicly discussed without asserting a wholesale engine supply deal.
- Joint development programs on diesel engine technology in the 2000s, leveraging Isuzu’s diesel expertise.
- No public, widely confirmed production contract in which Isuzu-built engines were sold to Toyota for Toyota-branded passenger cars.
- Recent statements emphasize cooperation on cleaner engine technology and emissions improvements, rather than a blanket engine-supply arrangement.
These points indicate a limited, technology-focused relationship rather than a full-scale supplier arrangement for Toyota’s main vehicle lineup.
Current status and future prospects
As of 2024–2025, there is no publicly documented evidence that Isuzu manufactures engines specifically for Toyota’s current passenger vehicles. Toyota remains primarily responsible for its own engine development and sourcing decisions, with collaborations shifting toward broader powertrain and emissions technology rather than supplying complete engines from Isuzu for Toyota vehicles. The two companies continue to collaborate on strategic topics, but not on delivering Isuzu-made engines for Toyota’s mainstream models.
Summary
In short, Isuzu does not routinely manufacture engines for Toyota’s passenger cars. Historical collaboration exists in the realm of diesel technology and emissions, but it has not translated into a dealer-ready, mass-produced engine supply for Toyota’s current lineup. Toyota’s powertrains are primarily developed in-house or with other partners, while Isuzu focuses on its own engine programs and select technology collaborations.

Who manufactures engines for Toyota?
Toyota's engines are manufactured by its own subsidiary, Toyota Industries Corporation, which develops and produces engines for use in many Toyota vehicles, such as the Avensis, Corolla, Crown, and Land Cruiser. In the U.S., manufacturing plants such as Toyota Motor Manufacturing Alabama (TMMAL), Toyota Motor Manufacturing Kentucky (TMMK), and Toyota Motor Manufacturing West Virginia (TMMWV) are also responsible for producing Toyota engines and related components.
Key manufacturers and facilities
- Toyota Industries Corporation: This company manufactures a variety of engines for use in Toyota vehicles worldwide.
- Toyota Motor Manufacturing Alabama (TMMAL): Located in Huntsville, this facility produces a significant number of 4-cylinder, V-6, and twin-turbo engines for models like the Highlander, Tundra, and RAV4.
- Toyota Motor Manufacturing Kentucky (TMMK): This plant, the largest Toyota manufacturing plant in the world, builds engines and transmissions for models including the Camry, RAV4 Hybrid, and Lexus ES 350.
- Toyota Motor Manufacturing West Virginia (TMMWV): Located in Buffalo, this is Toyota's only plant in North America that produces both engines and transmissions, including 4-cylinder engines, transmissions, and hybrid transaxles.
Does Isuzu make Toyota engines?
In August 2007 Isuzu and Toyota agreed to develop a 1.6-liter diesel engine for use in Toyota vehicles sold in European markets.
