A pivotal moment in Mazda engine history arrived in the 1960s with the development of the Wankel rotary engine. This was a game-changing innovation that set Mazda apart in the automotive industry. The rotary engine was unique due to its compact size, high power output, and smooth operation.

Mazda’s most famous rotary-engined car, the RX-7, launched in 1978. It became a legend for its performance and unique engine sound. The RX-7’s success on the global stage not only showcased Mazda’s engineering prowess but also solidified its reputation as an innovator.

Embracing Environmental Consciousness

As environmental concerns became more prominent, Mazda adapted its approach towards more eco-friendly engines. In the 1990s, the company introduced the Miller cycle engine in the Mazda Millenia. This engine was designed to improve fuel efficiency and reduce emissions, demonstrating Mazda’s commitment to environmental sustainability.


The most recent chapter in Mazda’s engine manufacturing story is the introduction of the SKYACTIV technology in the early 2010s. SKYACTIV represents a holistic approach to vehicle efficiency which encompasses not just the engine but the entire car.

The SKYACTIV engines are known for their fuel efficiency, reduced emissions, and enhanced performance. This technology reflects Mazda’s dedication to innovation while addressing the modern challenges of fuel economy and environmental impact.


Who Makes Mazda Engines?

Mazda’s engine manufacturing combines the best of both worlds: advanced technology and the irreplaceable touch of human craftsmanship. The heart of this unique blend can be found in Mazda’s Miyoshi Proving Grounds, a facility steeped in history and driven by dedication.

Preserving the Past

Nestled in a lush Japanese countryside, over 40 miles north of Mazda’s headquarters, sits the Miyoshi Proving Grounds. Established in 1974 primarily for diesel engine production, this plant now serves a unique purpose.

It specializes in producing engines in small volumes, mainly for older Mazda models like the first-generation MX-5 Miata and MPV minivan. The plant even supports vehicles as venerable as the Titan commercial truck, sold over 30 years ago.

Handcrafted Engines with a Personal Touch

The real magic at Miyoshi lies in the hands of its dozen skilled workers. Unlike modern mass-production facilities, the engine production process here is remarkably hands-on.

Each engine is built from scratch, with parts manufactured, assembled, and packed by the same set of hands. This personal approach to engine assembly ensures a level of quality and care that is hard to replicate in larger, automated factories.

Reviving Old Production Lines

Miyoshi’s production lines, transferred from the Hiroshima engine plant, are given a new lease of life. These lines, though aged, are meticulously maintained. The process involves cleaning, detailed inspections, and restorations, akin to revitalizing a vintage masterpiece.

The plant’s dedication to quality is evident in every step, from overhauling hydraulic control systems to reprogramming machinery and conducting rigorous quality checks.
